Kodak 800 SERIES service manual Failure Analysis, Cartridge Tubing Needle and Septum

NovaJet 800 Series Service Manual

Failure Analysis:

1.Ensure the cartridge is properly primed and pressure has been established inside the cartridge (see SetUp procedures) Note: When priming the cartridge it is important to ensure the suction end of the EasyPrime or NovaPrime assembly is flush against the cartridge jet plate. Prime cartridge using 3 consecutive 1 second bursts and then wait 5 seconds, repeat 4-6 times over a 1 minute period. A sucking noise should be heard from the EasyPrime or NovaPrime when procedure is performed correctly.

2.Ensure the reservoirs are properly attached to the female valves otherwise this may cause ink starvation in the ink delivery system after only 10 minutes of print operations.

3.Ensure the cartridge needle septum connector assembly is tightly secure. The assembly is composed of three parts which must be tightly twisted together (do not overtighten!). Also, ensure the printer is level on floor. A height difference from one side of the printer to the other can also cause ink starvation.

4.Ensure the septum/cartridge tubing needle is properly connected between the cartridge and carriage assembly. Replace reservoir tubing needle and/or cartridge tubing needle if pressure is lost after the procedure has been performed (a leak is present in the line).
