CM02: Color Contamination Repeated at Beginning of Every Page
CM02 displays as small amounts of color contamination that appear on top of a
page. The contamination is reduced after a couple of pages.
Picture of Color Mixing: Color Contamination
The printhead is covered with ink somewhere and the ink keeps wicking back to the
channels. This happens most often on printheads with paper guides since ink wicks
beneath the paper guide and forms a reservoir of ink that damages future prints.
Solution
1. Verify that the defect is beyond the threshold. If beyond the threshold, continue to the
next step.
2. Check if the correct maintenance process is applied (KWS + IPS). Use the correct
maintenance profile and re-evaluate the performance.
If not resolved, continue to the next step.
3. Run the color mixing recovery process (maint_clear_color_mix 1) and re-evaluate the
plots.
If not resolved, continue to the next step.
4. Power off the printer, remove the printhead, and thoroughly clean it manually.
5. If there is a paper guide, remove it and clean underneath it. If not resolved, contact
Customer Service and report error code CM02-03: Servicing process not effective.
