Introduction
This field repair case covers a TS VLF focus acquisition fault recorded as 2 . . 2 . . TS VLF TS VLF / error . Fault symptom TS VLF TH1.0 2 . . What the error message means error - edge detection. The case is written for service teams who need to separate CRB signal, Z-stage focus position and laser parameter checks before making component replacement decisions. Case reference: RS-20260514-0001.

Final test result
After stabilization, readiness checks and standardized proof outputs were exercised to validate production viability.
Technical notes
Focus faults are not synonymous with laser head failure for Kodak thermal CTP stacks. Compare edge-find vs focus-scan stages distinctly. Striping/white-line symptoms may correlate with LVD/actuation optics, cleanliness, modulation health, focal plane stability — evaluate in parallel.
