1. Rad or fluoro gain calibration requires repetition (common)
2. Paxscan detector has defect requiring mapping (occasional)
3. Paxscan detector defective (occasional)

First check

Repeat rad and fluoro gain calibration

Test point: Gain calibration with empty field
Expected: Artifact removed from images

2 more checks with pass and fail actions, 3 corrective actions, and part numbers are in ServiceForge. Connect ServiceForge to your AI

Calibration: Drive motor brake and movement caution

Verify brake engagement/release function and drive chain operation

Ranked causes

1. Drive motors require functional brake and movement verification (common)
2. Left drive motor requires speed and directional calibration (common)
3. Right drive motor requires speed and directional calibration (common)

First check

Squeeze handle without directional pressure

Test point: Drive handle, drive chains
Expected: Click sound; chains do not move

Calibration: Lateral shift hydraulic fluid and pressure caution

Purge air from hydraulic lines, verify fluid level, and assess pressure switch operation.

Ranked causes

1. Air in hydraulic lines causing gurgling noise (common)
2. Low hydraulic fluid level (occasional)
3. Pressure switch requires adjustment (occasional)

First check

Bring x-stage back so telescoping column sits over lift cylinders

Test point: X-stage position
Expected: Telescoping column positioned over cylinders
