Try the following solutions to resolve the issue. Solutions are listed in order, with the most
likely solution first. If the first solution does not solve the problem, continue trying the
remaining solutions until the issue is resolved.
• Solution 1: Align newly installed print cartridges
• Solution 2: Incorrect type of paper is loaded in the paper tray
• Solution 3: Make sure the protective tape is removed from the print cartridges
• Solution 4: Check if print cartridges are fully inserted
• Solution 5: Print cartridge might be defective
Solution 1: Align newly installed print cartridges
Solution: You must align the print cartridges to ensure excellent print quality.
To align newly installed print cartridges
1. When prompted, ensure plain white letter or A4 paper is loaded in the paper tray,
then press OK.
NOTE: If you have colored paper loaded in the paper tray when you align
the print cartridges, the alignment will fail. Load unused plain white paper into
the paper tray, and then try the alignment again.
The product prints a test page, aligns the print cartridges, and calibrates the
printer.
2. Load the page print side down on the right front corner of the glass, and then
press OK to scan the page.
When the On button stops flashing, the alignment is complete and the page can
be removed. Recycle or discard the page.
Cause: You installed new print cartridges that needed alignment.
If this did not solve the issue, try the next solution.
Solution 2: Incorrect type of paper is loaded in the paper tray
Solution: If you have colored paper loaded in the paper tray when you align the
print cartridges, the alignment fails. Load unused plain white letter or A4 paper into
the paper tray, and then try the alignment again. If the alignment fails again, you might
have a defective print cartridge.
