down a solid band of color with 33% ink load.
Color Test Failures:
-Example A above depicts complete ink starvation in magenta. This problem may be corrected by using the EasyPrime and establishing the required pressure inside the cartridge. Replace septum connector/needle if repeated attempts continue to fail.
-Example B above depicts partial ink starvation in magenta (ink fires at 100% at the beginning of each pass but then starves). This problem can be corrected by ensuring 19 ml of ink is present
inside the cartridge (level must be between 8 ml and 35 ml for proper operation – refer to NOTE below).
NOTE: To install ink into a cartridge or to verify proper cartridge ink level obtain syringe with tube extension from accessory kit. Pull 20 ml of ink into syringe. Lift cartridge stall position valve to up position to cut off ink flow. Temporarily remove septum connector from cartridge. Install ink into cartridge by depressing syringe plunger; pull back on plunger to remove excess ink (if any). Reconnect septum needle to cartridge and close valve actuator (lower) to restore ink flow to cartridge. The cartridge will need to be primed to restore negative pressure inside cartridge – refer to step 3 above.
5.Activate the Prime pattern.
Select UTILITY MENU – PRIME. Verify all colors are printed. Verify no clogs are present in the prime pattern. Manual or automatic jet compensation is provided up to 20 jets in each cartridge. Ensure the integrity of the diagonal lines are consistent and smooth. Clean or replace cartridge if unsatisfactory.
