  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.

NOTE: If you use a remanufactured toner cartridge, we do not encourage updating your printer's firmware.

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. For more information, you can read our article on the HP+ program.


2. Printer Door Open Error Status

When the cartridge door is not fully closed, an error message will be displayed. To resolve this, open the cartridge door and then securely close it against the body of the printer. If this doesn't work, we have listed the other reasons below:

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.
NOTE: The transfer belt holds the toner in place without the lock, so this solution should work effectively.

 

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.

4. Low Toner/Toner Life End/Replace Toner Error

The steps to fix a laser toner end-of-life error may vary depending on the printer model and manufacturer. Most of the time, simply resetting the printer to its factory default settings and unplugging the printer for 15 minutes do the work. However, if it doesn't work, check the following:

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.
Important Note: After successfully bypassing the 'Low Toner' error, monitoring the toner level is crucial. Lift the cartridge and assess its weight to check the toner level. It's likely near empty if it feels light and should be replaced promptly. Continued printing with an empty toner cartridge can damage your printer and result in poor print quality.

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 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.
What to do:
  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.

6. Printer Printing Wrong Colors

If your laser printer is using four colors - black, cyan, magenta, and yellow, eventually, one color may run out before another. For example, if you're printing a forest scene and the leaves appear more yellow than green, your cyan cartridge may need to be replaced.

Cartridge to troubleshoot if:
  • Trying to print BLUE, but it looks CYAN, then troubleshoot your MAGENTA.
  • Trying to print BLUE, but it looks MAGENTA, then troubleshoot your CYAN.
  • Trying to print RED, but it looks YELLOW, then troubleshoot your MAGENTA.
  • Trying to print RED, but it looks MAGENTA, then troubleshoot your YELLOW.
  • Trying to print GREEN, but it looks YELLOW, then troubleshoot your CYAN.
  • Trying to print GREEN, but it looks CYAN, then troubleshoot your YELLOW.
Solution:
  1. Check toner levels.
    Make sure that your cartridges have enough toner and that they are correctly installed. If there's little to empty toner, you will need to replace the cartridge.
  2. Check the color settings.
    Make sure that your printer's color settings are set to the correct color mode. For example, if you're printing a photo, make sure that the color mode is set to "photo" or "color" rather than "black and white" or "grayscale."
  3. Clean printer and components regularly.
    If you've tried other troubleshooting methods and the problem persists, you can clean your printer and other components as a last resort. For instructions on how to clean it, you can follow the steps in 'Dirty Toner or Printer' under 'Toner Not Recognized' Error.

7. Print Color Not Matching the Screen Color

Here's how to fix the issue of print colors not matching the screen colors by calibrating your computer screen. Note that specific options and settings may differ based on your printer and operating system. Below are the general steps:

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.)


8. Leaking Toner Cartridge

To handle toner leaks properly, take the following precautions:

  • Use toner vacuum only. Avoid using regular vacuums in vacuuming spilled toner powder as it can create a static charge and potentially shock you.
  • Wear a non-surgical face mask to avoid inhaling toner powder.
  • Put on rubber gloves to prevent skin irritation.

To clean the printer, follow the steps below:

Leaking toner cartridge.
  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.
NOTE: If the toner spill is extensive, it's best to hire a qualified copier servicing professional to clean your printer.

 

9. Squeaky or Grinding Noises from Printer

Unusual sounds from the printer often occur due to the moving and rotating parts such as the toner cartridge, imaging drum, fuser unit, and printer gears. Below are the main causes of unusual sounds in the printer, along with steps to locate and troubleshoot them:

1. Toner Cartridge Problems

To troubleshoot the issue, start by replacing the toner cartridge. If the problem is resolved after changing the cartridge, it suggests that the toner itself was causing the sound.

To address this issue, find the gears of the toner cartridge in the provided photo. Apply a small amount of specialized grease for mechanical parts using a Q-tip to lubricate the gears. Once lubricated, reinstall the previous toner cartridge. If the problem persists even after lubrication, please refer to the other potential causes of the noise mentioned below.

2. Cartridge Drum Problems

Drum axle or pin.
Drum Axle or Drum Pin

The drum gears rotate against the drum axle or pin. Over time, the plastic material of the drum gear can wear out. To address this, apply a small amount of specialized grease for mechanical parts to lubricate the drum pin using a Q-tip. Additionally, lubricate the inside of the drum gears while being cautious not to damage the drum itself. It is important not to use excessive lubricant as it may drip onto the printed page and cause smudging or other issues.

Copper Contact in Drum

Inside the drum, there is a copper contact that serves as an electrical connection. To ensure proper functionality, lubricate this copper contact with a small amount of conductive grease specifically designed for electrical contacts using a Q-tip. It's important to avoid using regular grease as it may interfere with the electrical conductivity. Take care not to bend or damage the electrical contact while applying the conductive grease.

OPC Drum and Wiper Blade Contact Point

If you hear a strange banging noise from your laser printer, lubricate the contact areas between the wiper blade and the OPC drum to reduce friction. Smooth movement of the wiper blade is crucial for cleaning off remaining toner. Insufficient movement can damage the blade and drum, causing the noise. To prevent this, use a specialized drum lubricant like zinc stearate. Dampen a lint-free cloth (or applicator specifically designed for lubrication purposes) with a small amount of the lubricant and gently apply it to the contact areas. This will reduce friction and resolve the printer's noise issue.

Developer Roller Contact

The developer roller contact rotates against a metal plate. To ensure smooth operation, apply a small amount of conductive grease to lubricate the contact area using Q-tip. If the contact of the magnetic roller is damaged, it can result in a clicking sound.

3. Fusers' Roller Bushings

If you hear a noise for a few seconds after you finish printing, it could be coming from the fusers. When the bushings wear down, they may create a squealing sound as they make contact with the rotating metal of the fuser roller shaft. If you prefer not to replace the bushings, you should at least apply high-temperature lubricants to the contact point between the bushings and the rotating metal of the fuser roller shaft using a Q-tip. Remember that fusers reach temperatures of 100 degrees or higher, so regular lubricants should not be used. Remember, less lubricant is better in this case.

4. Printer Drive Gears

If you have tried the above steps but to no avail, then the issue might be caused by the printer gears. The printer drive gears can become worn over time, and even minimal wear can lead to noisy printing. Although the wear may not be easily visible upon visual inspection, it can still impact the printer's performance. To address this issue, lubricate the gears using a specialized grease designed for mechanical parts using a Q-tip. It is important to use the appropriate amount of grease, as using less is generally better for optimal functioning.

5. Printer Cooling Fan

Printers often have a cooling fan positioned behind a grid to ensure proper ventilation and prevent overheating. However, because the fan is in constant motion and rotation, it can sometimes produce unusual noises.

Reduce printer fan noise with foam padding. Worn fan bushings can create a loud friction sound when the lubricant dries up. To reduce the noise, apply foam padding around the fan. This helps reduce the noise caused by the fan when it starts to wear out and the lubricant dries up.

6. Paper Feed Rollers' Shaft

One more rotating part that can cause issues is the paper feed rollers. It's important not to lubricate the rollers themselves as they come into direct contact with the paper during the feeding process. However, you can lubricate the shafts of the paper feed rollers using a grease specific for mechanical parts to ensure smooth rotation and operation.
