Print a cleaning page
During the printing process paper, toner, and dust particles can accumulate inside the printer and can cause
print-quality issues such as toner specks or spatter, smears, streaks, lines, or repeating marks.
Use the following procedure to print a cleaning page.
1. On the printer control panel, press the OK button.
2. Open the following menus:
●
Service
●
Cleaning Page
3. Load plain letter or A4 paper when you are prompted, and then press the OK button.
A Cleaning message displays on the printer control panel. Wait until the process is complete. Discard the
page that prints.
Visually inspect the toner cartridge
Follow these steps to inspect each toner cartridge.
1. Remove the toner cartridge from the printer.
2. Check the memory chip for damage.
3. Examine the surface of the green imaging drum.
CAUTION: Do not touch the imaging drum. Fingerprints on the imaging drum can cause print-quality
problems.
4. If you see any scratches, ngerprints, or other damage on the imaging drum, replace the toner cartridge.
5. Reinstall the toner cartridge, and print a few pages to see if the problem has resolved.
Check paper and the printing environment
Step one: Use paper that meets HP specications
Some print-quality problems arise from using paper that does not meet HP specications.
●
Always use a paper type and weight that this printer supports.
●
Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles,
voids, staples, and curled or bent edges.
●
Use paper that has not been previously printed on.
●
Use paper that does not contain metallic material, such as glitter.
●
Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in
Inkjet printers.
●
Use paper that is not too rough. Using smoother paper generally results in better print quality.
