Artifacts | Symptoms | Error codes | See also | Troubleshooting guides

Artifacts

• Artifact gallery
• Cloud or blotch-shaped artifacts appear in solids
• Missing a partial swath
• Bad hotlink cable (10-4968B or 10-3518B) can cause plot problems on TS VLF
• Light and dark lines between swaths on alternate plates
• GDAPI jobs have banding on-press

Symptoms

Chiller | Desiccant box | Edge detection | Firmware | Safety loop | Shutter

Chiller/coolant

• Chiller hose connections leak coolant
• The coolant in the chiller reservoir is clear
• Low levels of coolant in the cooling loop can contribute to chiller failure

Desiccant box

• Power supply to desiccant box is unreliable

Edge detection

• Print Console Sometimes Causes Subscan Shifts on Trendsetter NEWS Devices
• I upgraded my head firmware, and now edge detect doesn't work.
• Unable to find the edge of a plate, or subscan image shift

Firmware

• Parameters Change when Loading or Upgrading Head NVS

Safety loop

• Temperature or Safety Loop errors occur intermittently with no apparent cause

Shutter

• Shutter error—the focus sum suddenly drops to zero, the shutter is stuck, or you see error message [17686]
• Shutter sticks open, sticks closed, or does not operate smoothly
