troubleshooting problems with the color or black print cartridge
If the yellow arrow points to a print cartridge problem icon, the print
cartridge is either missing, improperly installed, defective, or is the wrong
print cartridge for the printer. To correct the problem:
1.
Insert the proper print cartridge if one is missing.
The printer needs both a black print cartridge and a color
print cartridge.
2.
Remove and reinsert the print cartridge if both print cartridges
are installed.
3.
Verify that the correct print cartridges are installed if there is still
a problem.
4.
Replace the cartridges if the problem persists.
solving problems with low ink
If the arrow points to the color or the black low ink icon, replace the relevant
print cartridge.
verifying that the problem is solved
If the arrow points to the print cartridge OK icon, both print cartridges are
operational and the problem is solved.
