NovaJet 800 Series Service Manual

Perform ‘Cartridge Maintenance & Testing’ before calling technical support or your service representative. These steps must be performed before cartridges will be replaced in any event.

Cartridge Maintenance & Testing

ENCAD cartridges are engineered for optimum reliability and compatibil- ity with ENCAD inks. If diminished print quality is observed, please follow these simple steps:

1.Scroll through the printer display to obtain total ink throughput. If the cartridge displays greater than 100% or 500 ml of ink throughput, the cartridge has reached its warranted life. ENCAD’s cartridge management system assures the highest quality and reliable productivity through the useful life of the cartridge, which may extend beyond the cartridge warranty period. In order to ensure the quality of output, the cartridges will shut off after 1280 ml (NJ850) or 1500 ml (NJ880) of ink throughput. If the cartridge has reached the end of its life it should be replaced. If not, go to Step 2.

2.Enabling open jet compensation (see ‘Manual Jet Bypass’) will often dramatically improve print quality. If enabling open jet detection and/or activating the manual jet bypass feature on problem jets (clogged/misfiring jets) found in the Prime pattern does not improve image quality, go to Step 3.

3.Cleaning the jet plate with distilled water and a lint-free cloth should clear any jets stopped by dust particles or other physical obstructions. Vigorously blot the gold jet plate area on the bottom of cartridge with the heavily dampened lint-free cloth. Repeat several times. For cartridges which have not been used for longer
