Ink Contamination on Yellow Printhead
Description of problem
In certain circumstances, the Yellow Printhead is cross-contaminated by aerosol coming from the Black Printhead. This occurs when the aerosol removal system in the Service Station ceases to work.
When this problem occurs you will actually see nozzles out and misdirected. In this situation Printhead Recovery will not help to resolve the problem since this is a permanent problem and eventually degrades the life of the Printhead.
Corrective Action
1. Replace the Yellow Printhead and the Black Printhead Cleaner.
