If your printouts have incorrect colors, try these solutions: Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software. Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary.
Check the Ink Cartridge Installed. One of the most common reasons behind color printing issues in the Canon printer is an empty cartridge. You should first check whether your cartridge still has ink. First, open the printer`s front door and remove the cartridge slowly and carefully.
If you accidentally insert your inkjet`s cartridges in the wrong color slots, most printers sense the error through circuits that check installed consumables and alert you with an on-screen message. Until you correct this type of installation mixup, your printer simply won`t operate.
Print color mismatch refers to a shift in the positions of colors that may occur when printing one image with multiple toner cartridges, causing printouts to appear blurry.
If the print positions slightly shift for the respective colors, use the following procedure to perform color print mismatch correction. Press (Settings/Registration) <Adjustment/Maintenance> <Adjust Image Quality> <Auto Correct Color Mismatch>.
If you install the wrong ink cartridge in your printer, you will likely receive an error message on your printer display that prevents you from using the printer. Printers are smart and most will be able to tell right away if the wrong cartridge is installed.
Printer damage

Yes, using refilled ink cartridges can actually cause permanent damage to your printer.

The error code you have is an indication of an internal problem with the printer. The best thing you can do is try resetting the printer using the instructions in this document. If resetting works – the printer will clear the error and continue to work.
Check for issues with the ink cartridges

Very low ink levels, using non-HP cartridges, and rough handling can cause print quality issues. Replace any non-HP or refilled cartridges with genuine HP cartridges. HP supplies are available from the HP Store and local retailers.

Make sure that none of the ink cartridges are empty. If the cyan or yellow run out, you`ll get a definite red/pink hue to the printouts. – Verify that the paper type setting in whatever application you`re using, matches the paper type you`re using.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.
