Processor Banding and Density Variations
Purpose
The purpose of this service bulletin is to communicate how to correct banding and density variations
within the PROCESSOR ASSEMBLY.
Problem
1. Horizontal banding that appears to repeat at a 2-inch interval, often more evident down the
center of the film when viewed in portrait mode.
2. Variation in density from one side of the film to the other, when the film is viewed in portrait
mode.
Cause
1. One or 2 ROLLERS of the set of 3 PROCESSOR PRESSURE ROLLERS is slightly out of
round causing differences in the pressure applied to the film during development. In severe
cases, some of the nickel plating will be worn off of a portion of the defective ROLLERS.
2. The LOWER FELT PAD in the STRIPPER ASSEMBLY may not be seated tightly against
the front metal portion of the STRIPPER BAR, or the felt may have become detached on one
end, or an UPPER FELT PAD has been installed in the LOWER PAD position.
Solution
1. Replace the set of 3 PRESSURE ROLLERS with a new set, SP78-8113-2102-1.
2. Replace or reposition the LOWER FELT PAD, SP78-8113-2069-2.
