Note: If the Resume light continues to blink or if the cradle doesn't move to the right side of the printer, take out both cartridges and reinsert them. When a print cartridge starts to run out of ink, replace it. If you do not have a replacement, leave the empty print cartridge in the cradle of the printer. The printer will not print with only one print cartridge installed. We recommend you keep spare print cartridges on hand.
