Technical Bulletin
11-08/01 EC27 or EC28 - Film Stopping in Processor (Reissue)
This Technical Bulletin is a revision and reissue of Technical Bulletin 14-04/01, EC27 - Film Stopping in
Processor.
Problem
Film moves through the PROCESSOR too slowly and the software times out, producing an Error Code 27
or Error Code 28.
Cause
Film did not start correctly into the PROCESSOR. There are several possible causes, in addition to CPU
PWA resistors R36 and R39 (see Technical Bulletin 21-11/98):
1. Bowed ENTRANCE GUIDES caused by over-tightening the MOUNTING HARDWARE. The bow
produces a high resistance in the film path. (See Solution 1.)
2. Metal ENTRANCE or EXIT ROLLER has broken loose from their SHAFT. (See Solution 2.)
3. Rubber ENTRANCE and EXIT PINCH ROLLERS are coated or hardened and cannot capture the
leading edge of the film. (See Solution 3.)
4. The ends of the SHAFT of the rubber ENTRANCE and EXIT PINCH ROLLERS are contaminated
and do not rotate freely in their BUSHINGS.
Solution
1. Remove the PROCESSOR ASSEMBLY and loosen the SCREWS and/or NUTS that secure the
ENTRANCE GUIDES (located on the underside). Check that the GUIDES are not bowed., then
tighten the HARDWARE only enough to keep the GUIDES from bowing.
2. Remove the metal ENTRANCE or EXIT ROLLERS and check that each DRIVE SIDE SHAFT is
correctly installed on the ROLLER. If it is not, remove the SHAFT, put a small drop of epoxy in the
ROLLER and slowly press the SHAFT back into the ROLLER. If you cannot install the SHAFT,
replace the ENTRANCE ROLLER (78-8100-0293-7) or EXIT ROLLER (78-8100-0431-3), as needed.
3. Clean both rubber ROLLERS with alcohol. If the surface is not soft and supple after cleaning, replace
the ROLLER (78-8113-2104-7).
4. Remove the ROLLERS from their BUSHINGS in the PROCESSOR and clean the ends of the
SHAFTS with a SCOURING PAD or STEEL WOOL until they are smooth. Clean the insides of the
BUSHINGS to remove any contamination. Check that the BUSHINGS rotate freely on the ends of the
SHAFTS before installing in the PROCESSOR ASSEMBLY. If the BUSHINGS are scored or still do
not rotate freely, install new BUSHINGS (8E2021, set of 2).
