Line Artifacts > 1mm (mm/Macro TPH Banding)
When a line runs the length of the film in the print direction — anywhere from a narrow 1-5 mm band to a wide band over 5 mm — you're looking at thermal-head (TH) banding, and the fix path is TH cleaning, escalating to a printhead calibration if cleaning alone doesn't clear it.
Applies to
DryStar 5300 (Type 5365/100)
Personnel
1 technician · Service-level technician — reads an STI2 test image for the banding pattern, cleans the thermal head per chapter 3.6, and runs a printhead calibration from the service menu if cleaning alone doesn't clear it (derived — source does not assign a formal skill-level label to this section).
