Locating the Cause of Scratching in the PROCESSOR/DENSITOMETER Area
1. Close and latch the PROCESSOR COVER.
2. Transport another sheet of film.
3. As the leading edge of the film arrives at the TRANSPORT ROLLERS just ahead of the
DENSITOMETER TURNAROUND, use the strip of film to actuate the DENSITOMETER/EXIT
SENSOR (to avoid a film jam error). Leave the SENSOR actuated for 10-15 seconds.
4. Grasp and remove the film before it enters the TURNAROUND.
5. Examine the film. If it does not have scratches, the problem is in the
DENSITOMETER/TURNAROUND. If it has scratches the problem is ahead of the DENSITOMETER
(FILM DIVERTER, FELT PAD, etc.). Advance to the next step to isolate the problem.
6. Lift the PROCESSOR HEAD SHIELD to expose the FILM DIVERTER and FELT PAD.
7. As the film enters the PROCESSOR, use the strip of film to actuate the DENSITOMETER/EXIT
SENSOR.
!
Caution
The film is hot after it passes over the heated DRUM. Use gloves while grasping and handling it.
8. Grasp and remove the film just after it passes the FILM DIVERTER. DO NOT allow it to touch the
FELT PAD.
9. Examine the film. If it has scratches, the FILM DIVERTER is the problem. If it does not have
scratches, the problem is the FELT PAD or the COOLING PLATE.
10. See paragraph 7-6-5 for recommendations for removing the cause of film scratches.
