Colors do not line up properly

Check the print cartridges

The print cartridges are automatically aligned when a cartridge is replaced. However, you might notice improvement in the print quality by performing the alignment procedure yourself. See Using the print cartridges.

Check the graphics placement

Use the zoom or print preview feature of your software to check for gaps in the placement of graphics on the page.

Lines or dots are missing from text or graphics

The printer may be in Ink-backup Printing Mode

The printer enters Ink-backup Printing Mode when one of the print cartridges is empty or removed. Replace the missing print cartridge with a new one (see Inserting the print cartridges).

Verify the ink levels of the print cartridges

One of the print cartridges may be low on ink. To view the ink levels, print a diagnostics page (see Printing a diagnostics page). For Windows, if the Toolbox is installed, you can find ink-level information by clicking the Estimated Ink Level tab. If the print cartridge is low on ink, replace it (see Inserting the print cartridges).

The print cartridges may need to be cleaned

Perform the auto-clean procedure (see Cleaning the print cartridges).

Check the print cartridge contact pads

The print cartridge contact pads might need cleaning. See Using the print cartridges.
