How to prevent ghosting in printing? Here is complete analysis and solution for printer printing ghosting problem.
When the printer experiences repeated blurred text or images, you can locate and solve the problem from multiple dimensions such as consumables, hardware, software, etc. according to the following systematic investigation plan.
1. Core causes: consumable failure
1) Toner cartridge/inkjet cartridge aging
Laser printer
Failure mechanism: The long-term use of toner cartridge photosensitive drum results in surface wear, or residual toner causes repeated development.
Repair plan:
① Remove the toner cartridge after power is cut off and use a lint-free cloth to gently wipe the surface of the photosensitive drum (avoid scratches);
② If the cleaning is ineffective, you need to replace the toner cartridge of the same model.
Inkjet printer
Failure mechanism: The nozzle blockage causes uneven distribution of ink, or the ink leaks ink to cause diffusion.
Repair plan:
① Perform the printer’s own “spray head cleaning” program (usually set in the control panel or driver);
② When multiple cleanings are ineffective, the ink cartridge needs to be replaced.
2) Consumable quality issues
Fault manifestations: Inadequate adhesion of inferior toner or excessive viscosity of ink, resulting in ink trace deviation.
Solution: Replace original or compatible consumables and avoid using inferior substitute products.
2. Hardware troubleshooting
1) Fixing component exception
Laser printer
Fault characteristics: Insufficient temperature of the fuser roller or the coating falls off, resulting in the toner not completely cured (representing that powder is easily lost in the printing).
Solution: Contact the official after-sales service to replace the fixing assembly, it is not recommended to disassemble it by yourself.
Inkjet printer
Non-hardware problems: When the paper is not dry, it is stacked and stored, and ink is contaminated to cause similar ghosting. You need to adjust your usage habits.
2) Contamination of transfer parts
Fault mechanism: The laser printer transfer belt/transfer roller absorbs toner, causing secondary transfer overlap.
Repair plan: After turning off the power, use alcohol cotton pads to clean the transfer parts (involving disassembly operation, it is recommended to be handled by a professional).
3. Software and settings optimization
1) Improper printing parameters
Failure: Image algorithm distortion in low resolution mode, or advanced image processing is not enabled.
Solution:
① Select “High Quality” or the highest resolution mode in the printing settings;
② Check the “Enable Advanced Image Processing” option (some drivers support).
2) Driver issues
Fault manifestation: The driver version is too low or conflicts with the system, resulting in abnormal image transmission.
Solution:
① Uninstall the existing driver, go to the printer official website to download the latest version and reinstall it;
② Try to use a temporary replacement for “general driver” (such as the PCL/PS driver that comes with Windows).
4. Influence of external factors
1) Inappropriate paper selection
Failure manifestations: Moist, too thin or rough paper can easily lead to uneven ink penetration.
Solution: Replace dry, flat adapter paper and match the corresponding paper type in the print settings.
2) The environment humidity is too high
Failure mechanism: When the humidity exceeds 60%, the paper absorbs and expands, affects the paper removal accuracy.
Solution: Keep the ambient humidity between 40%-60%, and keep the paper sealed to avoid long-term exposure.
5. Daily maintenance and calibration
1) Internal cleaning
How to operate:
① Use a dry cloth or cleaning rod to wipe key parts such as paper feeding wheels, toner cartridge slots after power is cut off;
② The laser printer can remove the toner cartridge and use a soft brush to clean the remaining toner inside.
2) Equipment calibration
Scenarios: The printhead/ink cartridge is offset after replacement of consumables or long-term use.
Operation method: Run the “Calibration Print Head” or “Align Ink Cartridge” function in the printer settings.
6. Special scene processing
Specific file ghosting: Check whether the file layers overlap and whether the transparency settings are abnormal (such as PDF/PS format files).
Continuous printing failure: The printer overheating causes the performance of the components to decline. It is recommended to pause the use for 10-15 minutes before trying again.
Problem solving priority
Consumable inspection: Priority cleaning or replacement of the toner cartridge/ink cartridges will be resolved by over 80% of ghosting problems.
Setting adjustment: Optimize printing resolution and paper parameters to ensure the basic configuration is correct.
Driver update: Fix software compatibility issues to avoid failures caused by driver exceptions.
Hardware cleaning: Professional cleaning or replacement for fixing and transfer parts.
Professional repair: If the above steps are invalid, contact after-sales inspection of hardware components such as fixing films, lasers, etc.
Experience tips:
Laser printer ghosting is mostly related to toner cartridges and fixing components, while inkjet printers need to focus on the nozzle and ink status;
It is recommended to clean the printer internally once a month, which can effectively reduce the incidence of failure.
