Print Head Maintenance
If your printouts become too light, or you see dark or light bands across them, you may need to clean the
print head nozzles. Cleaning uses ink, so clean the nozzles only if print quality declines.
You can check for clogged nozzles before you clean them so you don’t clean them unnecessarily.
Note: You cannot clean the print head if ink is expended, and may not be able to clean it when ink is low.
You must replace the ink pack first.
