Important for repacking and resetting of the Maintenance Cartridge as well as Nozzle1 checks.

Do nothing else in Service Mode except if you know what you are doing and have reference to an actual Service Manual.

1. Nozzle1 test : (gives TRUE nozzle check pattern for you ACTUAL head discharge output pattern) Very Revealing for true condition of BOTH sets of Nozzles From EACH of your print heads
2. Waste Ink Chip resetting : Repack your own waste tank and save Money. Chip MUST BE reset and waste tank repacked BEFORE the cartridge shows as full.
