Control Panel
To diagnose some problems, check the printer’s control panel, 
as described below.
Follow the guidelines in this table when you check the control 
panel lights:
Replacing an Ink Cartridge
❏ When the red   ink light flashes, one or more ink 
cartridges are low on ink.
❏ When the red   ink light stays on, you need to replace the 
cartridge(s).
When you print, you’ll also see a message on your screen 
telling you which cartridge is low or empty. 
When a cartridge is more than six months old, you may need 
to replace it if printouts don’t look their best. If the quality 
doesn’t improve after cleaning and aligning the print head, 
you can replace the cartridge even if the red   ink light is off.
