Ink Valve Failure
This is a challenging repair. If you have a current service contract this would be a covered repair but does not include shipping to Printware for the repair. The first video covers removing the print engine and the second video details replacing the ink valve.
CAUTION! Please be sure the Waste Ink Tray and Service Station are removed from the Print Engine before turning the print engine on its side. This will help reduce the chance that waste ink will run out of these items and into areas it should not be, causing damage and creating a lot of cleanup time. Try to finish this procedure as quickly as possible. Once the print engine is upright again, re-install the Waste Ink Tray as soon as possible.
