• Horizontal white lines

Canon PIXUS Printhead

What can be done to try to remedy these issues?

1. Clean the cartridge print head nozzles using alcohol and a cotton swab. The nozzles could be clogged, which leads to uneven dispension of ink. It's also possible to clean the print head via your printer's software (if there is a "Head Cleaning" or equivalent option).
2. Verify that the paper type in the printer matches the paper type listed in the printer's setup.
3. Check that the print head ribbon is securely attached, as it could have come loose.
4. Disconnect the printer from its electrical outlet, and clean the print head electrical contacts with alcohol to remove any paper dust that may have accumulated.
5. Restart both the PC and the printer, and then make sure that all connections are tightly secured.

If the above tips are not successful in solving your printer problems, then I would look at possibly replacing the ink cartridge altogether, as it may be an issue with the print head itself.
