Problem - - EC27 occurs after replacing the FAZ FILTER.
Cause - - The FAZ FILTER is bulging in the middle, which puts pressure on the UPPER PROCESSOR
ENTRANCE GUIDE PLATE.
Solution - - Replace the FAZ FILTER with one that does not bulge in the middle.
Problem -- Film did not get a positive start into the PROCESSOR because:
1. Bowed ENTRANCE GUIDES caused by overtightening of the mounting hardware during production.
The bow produces a high resistance in the film path. See Solution 1.
2. Metal ENTRANCE ROLLER is slipping on its SHAFT. See Solution 2.
3. Rubber ENTRANCE PINCH ROLLER has glazed or hardened and is no longer grabbing the leading
edge of the film. See Solution 3.
Solutions
1. Remove the PROCESSOR ASSEMBLY and loosen the SCREWS and/or NUTS holding the
ENTRANCE GUIDES (located on the under side). Check that the GUIDES are no longer bowed, then
tighten the hardware only enough to keep the GUIDES from bowing.
2. Remove the metal ENTRANCE ROLLER and check that the DRIVE SIDE SHAFT is securely attached
to 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 secure the SHAFT, install a new ROLLER
78-8100-0293-7.
3. Clean the rubber ROLLER with alcohol. If the surface is not soft and supple after cleaning, install a new
ROLLER 78-8113-2104-7.
TECH TIPS
A quick way to check SWITCH functionality is to open the TOP COVER and defeat the COVER
INTERLOCK. Put the LASER IMAGER in a Ready Condition (or warming up), i.e., FILM TRAY inserted
and FILM SAVER only partially removed. Flip open the TOP WIRE FILM GUIDE and insert a piece of
FILM into the PROCESSOR ENTRANCE CHUTE all the way until it hits the PROCESSOR ENTRANCE
ROLLERS. If the PROCESSOR ENTRANCE SWITCH is functioning and it detects the FILM, it will cause
an EC27 to be displayed on the LOCAL PANEL.
THEORY
"REMOVE FILM FROM DEVELOPER AREA (27)" is a SWITCH time--out error.
Error 27 occurs when FILM has not triggered the PROCESSOR EXIT SWITCH/SENSOR within 50
seconds after it triggered the PROCESSOR ENTRANCE SWITCH/SENSOR. In this case, the FILM
should be found inside the CLAM SHELL, not sticking out of the PROCESSOR EXIT ROLLERS. The
PROCESSOR MOTOR gets turned off as soon as the error is detected, so the FILM should not change
position after the error is reported.
