Toner Not Installed Properly

Non-recognition errors can occur if the toner is not installed correctly. As mentioned earlier, there are two main types of laser toner cartridges: those integrated with the drum unit and those that are separate. It's important to be aware of this distinction because the installation process varies between them.

For more information, you can check out our how-to-install ink and toner cartridges video. Alternatively, you can follow the steps below, which are generally applicable to most laser printer models.

Toner Integrated to Drum

1. Step 1.
   Gently remove the toner cartridge from the printer while wearing rubber gloves, taking care not to touch the sensitive components. It's a good practice to place the cartridge assembly on a disposable piece of paper to avoid any potential toner spills.
2. Step 2.
   Next, realign the new toner cartridge with the tracks inside the printer and gently push it until it clicks into place. If toner gets on your clothing, wipe it off or wash it with cold water immediately.

Toner Not Integrated to Drum

1. Step 1.
   Wearing rubber gloves, remove the drum unit and toner cartridge assembly from the machine. Putting the assembly on a disposable piece of paper is a good idea in case you spill any toner.
2. Step 2.
   Next, take the toner cartridge out of the drum unit and carefully reinstall it back into the drum. Make sure it's firmly in place and locked into position. If you get toner on your clothing, wipe it off or wash it with cold water immediately.
3. Step 3.
   Finally, align the drum unit and toner cartridge assembly with the tracks in the printer and slide it in until it clicks into place.

Toner Installed in the Wrong Color Slot

This is common for a laser printer that uses multiple toners.

• If you have the right toner for your printer, check if it is installed in its correct color slot. Each cartridge should be labeled with the color it represents.
• If it is installed in the correct color slot, turn the printer off and back on to reset the system.

For installation instructions, check our how-to-install ink and toner cartridges video for more information.

Dirty Toner or Printer

Proper maintenance of the toner cartridge and printer, including cleaning them, is essential for ensuring the longevity and optimal performance of your toner and printer. Failure to maintain them may result in them becoming dirty, damaged, or clogged, which could interfere with the printer's ability to recognize toner.

1. Step 1.
   Prepare rubber gloves, mask, toner vacuum (not regular vacuum), activated toner cloth, isopropyl alcohol, cotton swabs, and paintbrush.
2. Step 2.
   Let your printer cool down prior to cleaning for an hour before cleaning so you don't electrocute yourself.
3. Step 3.
   Wear rubber gloves and a mask before removing the printer's toner cartridge and drum unit. Place them in an area that is away from sunlight. Be careful not to touch the surface of the drum unit to avoid damaging it.
4. Step 4.
   Wipe your toner cartridge(s) using an activated toner cloth. As you wipe, place the toner cartridge on a second activated toner cloth to remove any excess toner. This helps to clean the cartridge and prevent any leftover toner from getting onto other surfaces.
5. Step 5.
   Place the toner vacuum inside the printer chassis and use it to slowly remove any spilled toner from the internal components. Be sure to avoid touching any internal surfaces inside the printer with the vacuum.
6. Step 6.
   Use a paintbrush to clean any hard-to-reach spots, including any narrow and deep openings or cracks in the printer where toner powder may have accumulated. Use the toner vacuum to get rid of any dust or debris that was left behind after removing all of the toner from these crevices.
7. Step 7.
   Next, dip a cotton swab in Isopropyl alcohol and gently rub the corona wires with it. Make sure to clean both sides of the wires and change the cotton swab when necessary. Be careful not to apply any pressure since the wires are fragile and expensive.
8. Step 8.
   Clean the paper feed roller after cleaning the corona wires. Using a cotton swab dipped in Isopropyl alcohol, clean the paper feed roller by rubbing it in a circular motion to eliminate any toner build-up. Remember to replace the cotton swab when necessary.
9. Step 9.
   Reinstall all the parts you removed, including the toner cartridge and drum unit, and close the printer but don't turn it on yet.
10. Step 10.
    Clean and disinfect the outside of your laser printer. Use an activated toner cloth and Isopropyl alcohol to remove any dust and debris that has accumulated on the exterior surface of your printer.
11. Step 11.
    Turn on your printer and check if your laser printer recognizes the toner this time.

Laser Printer Regional Coding

If you purchased your printer in Region A and tried to install toner cartridges purchased in Region B, your printer will not accept them due to region coding enforcement. This applies to some printers, regardless of whether you are using original or remanufactured cartridges.

Before following the steps below, it's important to determine if your printer has region coding. To do this, simply search for your printer model and the term "region coding" on Google. For example, you can search for "HP DeskJet 2700 region coding."

If the results show that your printer does not have region coding, you can check the other reasons why you're experiencing non-recognition problems. If your printer does have region coding, you have several options:

• Option 1:
  You can choose to continue purchasing cartridges from your previous region, but keep in mind that this can be costly due to shipping and additional fees.
• Option 2:
  You can try swapping the cartridge part with the chip on it. However, this should only be attempted with caution and at your own risk. There are YouTube tutorials available to guide you through the process.
• Option 3:
  Reach out to your printer manufacturer and inquire about the possibility of changing the region code of your printer. It's important to note that the initial support staff may not be familiar with this option. In such cases, politely request to speak with a supervisor or manager who can provide further guidance on resolving the issue. Please be aware that printer manufacturer support may not extend assistance if you are using third-party cartridges.
• Option 4:
  If you want to minimize any potential risks, it may be worth considering purchasing a new printer that is specifically designed for the region you have relocated to. Look for a printer that offers features such as the ability to disable cartridge protection, no region lock, and the option to turn off automatic firmware updates. These features will provide you with the flexibility to use cartridges from different manufacturers and give you greater control over the printer's software.

Printer Firmware Problem

If you are using third-party toner cartridges, check your printer's firmware to see if it has been updated. Printer manufacturers like HP and Epson release firmware updates not just to fix bugs but also to restrict the use of third-party toner cartridges. If this is the case, you may need to downgrade your printer's firmware version to continue using remanufactured toner cartridges. You can follow our downgrade instructions for HP and old firmware download steps for Epson.

Other Possible Reasons

Printer manufacturers have implemented measures to limit the use of third-party ink or toner cartridges, apart from firmware updates. HP's HP+ program is an example of such measures. When you activate HP+ on a compatible printer, it will only work with genuine HP cartridges throughout its lifespan.

Obstructions

Check if there are any obstructions or debris inside the toner cartridge slot that may be preventing the cartridges from seating properly. If you find any debris, remove it carefully. If you don't see any debris, but notice dirt or dust inside the slot, clean it by following the 'Dirty Toner or Printer' steps under Toner Not Recognized Error.

Toner Not Fully Seated.

Another possible reason for this laser printer toner problem might be that one or more toner cartridges are not sitting correctly. In most cases, the black cartridge lock on the left side of the printer may be broken, causing the black toner cartridge to stick out on the left side and preventing the door from closing.

To know if this is really the case, you can remove all the toner cartridges and try to close the printer door. If it closes, it means that the toner(s) is not fully seated. Follow the steps below to fix this:

Solution:

1. Step 1.
   Remove all toners.
2. Step 2.
   Install one toner at a time, starting at the bottom and working your way back, closing the door each time a cartridge is installed.
3. Step 3.
   If the black toner won't close, look on the left side and find a beige, black, etc, piece hanging down where the toner slides in.
4. Step 4.
   Use a small piece of cardboard to move the piece up and out of the way, and then use the cardboard as a shim to hold the piece up while inserting the toner.

Tab in the Printer

If the previous solution does not work, it is possible that a printer tab may be preventing the door from closing properly.

Solution:

1. Step 1.
   Check for a tab in the printer hanging down. Sometimes it is white in color and located in the upper left corner. This varies depending on your printer's brand and model.
2. Step 2.
   Once found, push the tab up to snap everything in place. The door should now close completely.

Wrong Toner Cartridge

Ensure to use the correct toner cartridge for your printer, as not all cartridges that look the same will work. If you're not sure which toner to use, check out our tips on how to find the correct toner for your printer.

Here are some steps to help you find the right toner cartridge for your printer:

• Option 1:
  Look for the cartridge model number on the top or front of an empty laser toner cartridge. The model number is usually a combination of numbers and letters, such as TN227.
• Option 2:
  Check your printer manufacturer's website. Enter your printer model on the manufacturer's website, and you'll see a list of compatible toner cartridges. You can find your printer model in the manual.
• Option 3:
  If you're still unsure, reach out to the printer manufacturer's support team for assistance. Don't hesitate to ask for help.

Obstructions or Debris

Make sure there is nothing blocking the toner cartridge slot in your printer that could prevent the cartridges from fitting properly. If you see any debris inside, remove it carefully. If there is no debris, but there is dust or dirt, you can clean it by following the steps under the 'Dirty Toner or Printer' section in the Toner Not Recognized error guide.

Did not Remove Tape or Plastic Coverings

Make sure to remove any protective coverings, plastic strips, or tabs from a new toner cartridge before installing it into your printer. These coverings may prevent the cartridge from fitting properly, so removing them before use is important. Check our how-to-install ink and toner cartridges video for more information.

Installed in Wrong Color Slot

If you have a laser printer that uses multiple toners, it's important to ensure each toner is installed in its correct color slot. This information can usually be found on the cartridge label, which indicates the color it represents. If you have the right toner for your printer, but it doesn't fit, double-check the color slot. For detailed installation instructions, you can also refer to our how-to-install ink and toner cartridges video.

Toner Not Installed Properly

Non-recognition errors may occur if the toner cartridge is not installed properly. Laser toner cartridges come in two main types: those integrated with the drum unit and those not.

If you are unsure how to install the toner cartridge correctly, check our how-to-install ink and toner cartridges video for more information. Alternatively, you can follow the steps provided in the 'Toner Not Installed Properly' section of the 'Toner Not Recognized' error guide.

For New Remanufactured Toner Cartridges

1. If it's new, double-check that the toner cartridge is the right toner for your laser printer.
2. Ensure that you remove any protective coverings, plastic strips, or tabs attached to the toner cartridge before installing it.
3. Remove and reinstall the toner cartridge properly and securely into the correct slot.

If you have installed a new remanufactured toner and are still encountering errors, you can try resetting the toner chip using a reset tool. Keep in mind that this may not always work, and some printers may not recognize refilled cartridges even with a reset chip. In such cases, you can try overriding the error message using the following options:

• Option 1:
  Press and hold the "Cancel" or "Stop" button on your printer for 10 seconds. This should reset the printer and allow it to recognize the remanufactured toner cartridge.
• Option 2:
  Access the printer's settings menu and look for an option to disable the "Cartridge Check" or "Toner Check" feature. Disabling this feature will prevent the printer from checking the cartridge's authenticity and may enable you to use the remanufactured toner cartridge without any issues.

For Non-new Remanufactured Toner Cartridges

1. Remove the toner cartridge from the printer and assess its weight. If it feels light, it's likely near empty and should be replaced promptly. Printing with an empty toner cartridge can damage your printer and result in poor print quality.
2. If the toner cartridge still feels heavy, gently shake it from side to side. This can help redistribute the remaining toner and allow it to be used more effectively.
3. Clean the contacts on both the toner cartridge and inside the printer. Dust or debris on these contacts can disrupt communication between the printer and cartridge. Refer to the 'Dirty Toner or Printer' section under the 'Toner Not Recognized' error for detailed instructions on cleaning the contacts.

If none of the above works, we suggest trying to override the error message by following the steps mentioned in 'New Remanufactured Toner Cartridge' section under 'For New Toner Cartridges'.

Poor Print Quality Due To Toner Cartridge Problems

Low Toner Level

When the toner level is low, the printer may produce faded or light printouts. Ensure that the toner cartridge is not empty and replace it if necessary, as continuing to print with an empty toner cartridge can cause damage to your printer and result in poor print quality. To check if your toner is really running low, you can follow the tips below.

1. Step 1.
   Remove the toner from the printer and assess its weight.
2. Step 2.
   If it's still heavy, proceed to Step 3. If it feels light, replace the toner cartridge immediately to not damage the printer.
3. Step 3.
   If the toner cartridge is new or has enough toner, wearing rubber gloves, shake it gently sideways up to 6 times to redistribute the toner powder. Once done, install it again.

Dirty Toner and/or Printer Components

Dust or debris on the contacts can cause blurred or smudged prints. For instructions on how to clean it, you can follow the steps in 'Dirty Toner or Printer' under 'Toner Not Recognized' Error.

Toner Buildup Inside The Printer

Take a close look inside the printer, focusing on areas where toner buildup is likely to occur. Pay attention to the toner cartridge cavity, the paper path, and the drum unit. If there's a toner buildup, then it is the reason why you're getting blurred or smudged prints. That said, you also need to clean it. For instructions on how to clean it, you can follow the steps in 'Dirty Toner or Printer' under 'Toner Not Recognized' Error.

Deformed or Damaged Toner Cartridge

Toner cartridges can get deformed or damaged when mishandled, installed incorrectly, or due to some environmental factors like exposure to extreme temperatures, humidity, or direct sunlight. That said, carefully examine the exterior of the toner cartridge for any visible signs of deformation, cracks, or other damage. Pay attention to the drum surface and the connections and contacts on the cartridge. If damaged, replace it before using your printer again.

Poor Print Quality Due To Paper Problems

Type of Paper Used

• Incompatible paper.
  Only use printer paper that is designed for laser printers. These papers are manufactured to meet the necessary specifications for reliable printing and minimize print issues. Incompatible paper, such as paper designed for a different printing technology (e.g., inkjet paper), may not be suitable for laser printers and can cause issues with print quality.
• Low-quality paper.
  Low-quality paper may have uneven surfaces or excessive moisture content, leading to poor toner adhesion and potential smudging. Paper Coating. Coated or glossy paper has a smooth, shiny surface that can affect toner adhesion. If the toner is not properly fused to the paper surface, it can lead to smudging or smearing.
• Recycled or Heavily Textured Paper.
  Recycled paper often has a rougher texture due to its composition, which can cause uneven toner distribution and result in blurred or smudged prints. Heavily textured paper, such as linen or textured cardstock, can also disrupt the smooth toner transfer process and impact print quality.

1. Choose high-quality, laser-compatible paper.
   Look for paper specifically designed for laser printers.
2. Select the appropriate paper weight.
   Different types of documents may require different paper weights. Ensure you're using a paper weight that is suitable for your print job. Thicker papers generally offer better print results and are less prone to smudging.

Paper Jams

Paper jams can disrupt the printing process and result in lines or streaks on the page. Clear any paper jams and remove any debris from the printer to prevent this issue.

Misaligned Paper

Ensure that the paper is loaded correctly in the tray and that it is not skewed or misaligned. If it is, adjust the paper guides to ensure proper alignment.

Poor Print Quality Due To Laser Printer Drum Problems

Worn-out Drum or Fuser

To determine whether it's the drum or fuser that is causing print quality issues in your laser printer, you can follow these steps:

1. Step 1.
   Start by printing a test page from your printer. Make sure to use a plain white sheet of paper for the test.
2. Step 2.
   Carefully examine the test page for any print quality issues and analyze the print defects. Blurred or smudged prints that are consistent throughout the page are more likely caused by a worn-out drum. On the other hand, if the print defects are mainly concentrated in a particular area of the page, it could indicate a fuser problem.

If you have identified the worn-out component, ensure to replace it before using the printer again.

Scratched or Dirty Drum

Carefully examine the surface of the drum for any visible scratches, marks, or dirt. The drum is a cylindrical component usually positioned near the toner cartridge. It is responsible for transferring the toner onto the paper during printing.

• If dirty, clean it.
  Dirt or debris on the drum can also interfere with the smooth transfer of toner and affect print quality. Gently clean it using a lint-free cloth or a soft, dry brush. Be cautious not to apply excessive pressure or touch the drum with your fingers, as it is a sensitive component.
• If scratched, replace it.
  Scratches on the drum can cause toner to accumulate in those areas, resulting in lines or streaks on the printed page. If you observe visible scratches or marks on the drum surface, it is recommended to replace the drum unit. Scratches cannot be repaired, and a damaged drum can significantly impact print quality.

Other Reasons for Poor Print Quality

Worn-out Wiper Blade

Replacing the worn-out wiper blade can help improve print quality, as it ensures proper cleaning of the drum or imaging unit and prevents toner buildup that can lead to print defects like lines or streaks on the page. To check if it is indeed causing the print quality issue, you can:

1. Step 1.
   Locate the wiper blade. The wiper blade is usually positioned near the drum or imaging unit. It is a thin, rubber-like strip that moves across the surface of the drum or imaging unit to clean off any excess toner.
2. Step 2.
   Inspect the wiper blade. Carefully examine the wiper blade for signs of wear or damage. Look for any visible cracks, tears, or unevenness in the blade's surface. A worn-out wiper blade may appear frayed or worn down.
3. Step 3.
   Check for toner residue. If the wiper blade is worn out, you may notice an excessive buildup of toner residue around the blade or on the drum or imaging unit. This can indicate that the blade is not effectively cleaning the drum or imaging unit surface.

If you observed significant wear or damage to the wiper blade, or if you have noticed an excessive buildup of toner residue around the blade or on the drum, then it is time to replace it.

Printer Driver Issues

Ensure that you have installed the correct printer driver for your printer and that it is up to date. Outdated or incorrect drivers may affect print quality.

Damaged Transfer Roller

If the transfer roller is damaged, you will need to replace it. The transfer roller is typically located underneath the toner or imaging unit. It is a long, cylindrical roller that comes in direct contact with the paper during the printing process. To check if it's the root cause, follow the following:

1. Step 1.
   Locate and inspect the transfer roller. Carefully examine the surface of the transfer roller for any visible signs of damage, such as scratches, dents, or worn-out areas. Damage to the transfer roller can disrupt the smooth transfer of toner, leading to lines or streaks on the printed page.
2. Step 2.
   Replace the transfer roller if damaged: If you observe any significant damage or wear on the transfer roller, it is recommended to replace it. Damaged transfer rollers cannot be repaired, and a replacement roller is necessary to restore proper printing functionality.

Calibrate with a tool.

You can calibrate your computer screen using an advanced calibration tool like a colorimeter or spectrophotometer. Note that using a calibration tool will help you achieve the same level of accuracy as professional calibration tools.

Calibrate without a tool.

If you choose to calibrate without a tool, you can use the built-in calibration tools on your computer's operating system.

For Windows PC:
Windows Search > search for 'display calibration' > Calibrate display color. (Adjust the brightness, contrast, and color settings as directed on the screen until the colors appear true to color.)

For Mac:
System Settings > Displays > Color > "Calibrate". (Using the toner vacuum, take out any remaining dust or debris after removing all of the toner from these gaps.)

To clean the printer, follow the steps below:

1. Unplug the laser printer and let it cool for an hour before cleaning to prevent burns from hot printer parts.
2. Carefully uninstall the toner cartridge and dispose of it in a sealable plastic bag.
3. Use sturdy, flat-edged cardboard to scrape the toner out of the printer, storing it in the same sealable plastic bag.
4. Wipe away the remaining toner powder inside the printer using a dry lint-free cloth or paper towel. Avoid dampening the cloth or paper towel, as damp wipes can cause toner powder to stick to printer components and damage them during operation. For additional instructions on how to clean laser printer, you can follow the steps in 'Dirty Toner or Printer' under 'Toner Not Recognized' Error.
5. Use a broom and dustpan, if necessary, to sweep any remaining toner powder on the floor.
