Kodak 800 SERIES service manual Clearing Cartridge Misfires, Multiple Cartridge Failures

NovaJet 800 Series Service Manual

Clearing Cartridge Misfires

-Press lightly against jets with a water/alcohol moistened lint-free cloth. Blot gold jet plate area, do not wipe.

-Insert cartridge and initiate a Color Test @ 100% in the 2-pass mode.

Note: running the color test in the single pass mode severely reduces printhead resistor life.

For severe clogs use ultrasonic cleaner (30-40 sec) or hot water (10-15 sec) to break down kogation (clogging of jet plate holes) at nozzle.

Figure 4-13. Adjacent Jet Misfire (Cyan).

Note: Adjacent misfires in the prime pattern will cause microbanding. These types of misfires must be manually compensated or cleared through cleaning procedures.

Multiple Cartridge Failures

-Assuming cartridges/flex driver cables are clean and connectivity is good recommend to customer to replace service station (should be replaced every 6 months). Check ink lot codes of possible contamina- tion. Contact technical support.
