Perform Print Head (TH) Calibration

Recalibrate the DryStar 5300's thermal print head (TPH) profile whenever vertical stripes become visible in the medical service test image — after the TH cleaning procedure has already been run, since this calibration only compensates macro-TPH banding wider than 10-15 mm, never sharp-edged artifacts.

Applies to
DryStar 5300 (Type 5365/100) — source Chapter 3.6, Repair and Service: Adjustments and calibrations, Edition 1, Revision 7 (2006-01-26), §2.3 Print Head (TH) Calibration.
Personnel
1 technician · Service-level technician — operates the Service Command Session web UI (not the key-operator menu), measures a printed calibration sheet's 32 fields with an external calibrated densitometer, enters the readings into the browser table, evaluates the resulting medical test image for macro-banding, and follows the repeat-or-replace-drum decision branch. Requires the TH cleaning procedure (chapter 3.6 §3.2) to already be complete before starting (derived — source does not assign a formal skill-level label to this section).
