Initial print quality check
Before troubleshooting print problems, perform the following:
• Make sure that the printer is located in an area that follows the recommended operating environment
and power requirement specifications.
• Check the status of supplies. Replace supplies that are low or empty.
• Load 20‑lb (75-80 g/m
2
) plain letter or A4 paper. Make sure that the paper guides are properly set and
locked. From the control panel, set the paper size and type to match the paper loaded in the tray.
• From the control panel, navigate to Settings > Troubleshooting > Print Quality Test Pages.
• Print and keep the Menu Settings Page. The original page is used to restore the custom settings if
necessary.
• On the Menu Settings page, check if the print resolution is set to 600 dpi and the toner darkness is set
to Normal.
• Check the toner cartridges for damage, and replace if necessary.
• Make sure that the correct print driver is used to prevent print problems. If the wrong print driver is
installed, then incorrect characters could print and the copy may not fit the page correctly.
