To maintain print quality, thoroughly clean the mopier/printer:

Every time the toner cartridge is changed
After printing approximately 15,000 images
Whenever print quality problems occur

Component	Cleaning method/notes
Outside covers	Use a water-dampened cloth. Do not use solvents or ammonia-based cleaners.
Inside general	Use a dry, lint free cloth. Remove all dust, spilled toner, and paper particles.
Paper pickup, feed, and retard rollers	Use a water-dampened, lint-free cloth.
Separation pad	Use a dry, lint-free cloth.
Registration roller	Use a dry, lint-free cloth.

CAUTION: To avoid permanent damage to the toner cartridge, do not use ammonia-based cleaners on or around the mopier/printer.

WARNING: Before beginning these steps; turn off the printer and unplug all power cords to avoid shock.
Avoid touching the adjacent fusing area in the left door, it may be hot

Cleaning spilled toner

Defective toner cartridges can cause toner leaks. After a paper jam has occurred, there may be some toner remaining on the rollers and guides inside the printer. The images that print immediately after the jam may pick up this toner.

Clean spilled toner with a cloth slightly dampened in cold water. Do not touch the Transfer roller with the damp cloth.

Do not use a vacuum cleaner unless it is equipped with a micro-fine particle filter.

HP LaserJet Printers - Touching or Cleaning the
Transfer Roller and Print Quality Issues

ISSUE: Cleaning an HP LaserJet printer's transfer roller with inappropriate materials, or touching it with fingers may damage the roller and cause print quality issues.

SOLUTION: If the transfer roller is causing print quality problems, clean it with a dry, lint-free cloth. During the cleaning process, do not touch the transfer roller with fingers. Replace the transfer roller if cleaning it does not eliminate the print quality problem.

SUMMARY: The Transfer Roller in an HP LaserJet Printer is a long (at least 8 inches) black sponge roller that sits horizontally under the toner cartridge (in most HP LaserJet printers). This roller is responsible for transferring the electrical charges that hold the toner particles in place on the page before the fusing process.

Oils from the skin can cause the roller to be less effective in transferring these charges to the paper. This can result in areas on the printout where toner is faded or missing.
