Print a cleaning page
Print a cleaning page to remove dust and excess toner from the fuser if you are having any of the following
problems:
● Specks of toner are on the printed pages.
● Toner is smearing on the printed pages.
● Repeated marks occur on the printed pages.
Use the following procedure to print a cleaning page.
1. From the Home screen on the product control panel, touch the Setup button.
2. Touch the Service menu.
3. Touch the Cleaning Page button.
4. Load plain letter or A4 paper when you are prompted.
5. Touch the OK button to begin the cleaning process.
The product prints the first side and then prompts you to remove the page from the output bin and
reload it in Tray 1, keeping the same orientation. Wait until the process is complete. Discard the page
that prints.
Inspect the toner cartridge for damage
1. Remove the toner cartridge from the product, and verify that the sealing tape has been removed.
2. Check the memory chip for damage.
3. Examine the surface of the imaging drum on the toner cartridge.
CAUTION: Do not touch the roller (imaging drum) on the cartridge. Fingerprints on the imaging drum
can cause print-quality problems.
4. If you see any scratches, fingerprints, or other damage on the imaging drum, replace the toner
cartridge.
5. If the imaging drum does not appear to be damaged, rock the toner cartridge gently several times and
reinstall it. Print a few pages to see if the problem has resolved.
Check the paper and printing environment
Use paper that meets HP specifications

● The printing is too light or seems faded in areas.
● Specks of toner are on the printed pages.
● Toner is smearing on the printed pages.
● Printed characters seem misformed.
