Print Quality Issues

Cartridge Misfires (Intermittent Banding)

Cartridge or print head misfires (clogged jets or misfiring jets) lead to
microbanding in prints and can cause operational downtime. The
Prime pattern tests all cartridge jets. Activate the Prime pattern
several times to verify the problem. Any clogged jet or misfiring jet
should be cleared through cleaning of the cartridge jet plate (See
'Routine Maintenance') or through Manual Jet Bypass (up to 20 jets
may be manually bypassed in each color to maintain satisfactory
print performance).
Note 1: Satisfactory print performance is defined for each give
mode:
2x4 mode
1x8 mode
1x4R
1x4L
Note 2: Warranty is applied to cartridges that have 10 or more
defective jets (100% filled blocks only.)
