Diagnosing Inkjet Banding Without Random Adjustments

Record the banding pattern, run the prescribed diagnostic checks and change one variable at a time. Different causes can produce similar-looking lines.

Capture a useful baseline Save the file, print mode and media information and photograph the defect at a useful scale. Compare the nozzle-check result with the machine instructions. Note whether the problem follows the artwork, repeats across the media or appears only under one mode.

Test a single explanation Use a known test file and the approved media setup. Follow the manufacturer’s alignment or feed procedures where indicated. Keep before-and-after output instead of altering several RIP controls at once. Escalate unresolved defects with the complete record.
