TROUBLESHOOTING
2.
FILMS ARE TOO LIGHT
A. Confirm the following initial requirements for AT2000XR Automatic film processing;
1. Proper X-Ray exposure setting, underexposure will create light films.
2
Film is not outdated (within manufacturer's recommended processing life) or defective.
3
Film used is designed for Automatic Processing
4
Film / screen combination is correct per manufacturer's specifications.
5. Films are PROCESSED AFTER READY LIGHT ILLUMINATES.
6. Chemistry used is designed for roller transport processors.
B. Check the chemistry agitators freely spins (chemistry circulation) - Disassemble the agitator assemblies
as depicted in the BASE ASSEMBLY section, (page 48). Analyze the agitator per the check sequence
listed in TROUBLESHOOTING GUIDE SECTION 1 - CHEMISTRY AGITATOR PROBLEMS
C. Check the chemistry temperature for being too COLD (temp. setting of 82°F NOT achieved) -
Preview the processor's temperature setting as follows; POWER ON, push and hold the DISPLAY SET-
TEMP button on the keypad. The value displayed will start flashing, if NOT 82° then a readjustment
must be made as follows;
1. Open the flip lid on the top side of the Electronics Module, push and hold the DISPLAY SET- TEMP
button on the keypad and rotate the potentiometer until 83 is displayed.
2. Once reaching 83, slowly rotate counterclockwise until 82°F is achieved. (The processor's heat
control & display can be reviewed FUNCTION MODES FUNCTION CHART, page 15)
3. If chemistry temperature is below 82°F, and the display pre-set is 82°F - Analyze the heat control
components per the check sequence listed in TROUBLESHOOTING GUIDE SECTION 1 -
CHEMISTRY TEMPERATURE CONTROL PROBLEMS, Item D provided on page 27.
D. Check the CHEMISTRY REPLENISHMENT level control and pumping rate;
1. Inspect the both developer & fixer Drain Tube washer condition - Must be in good condition
2. Confirm that both developer & fixer Drain Tubes firmly seat in their drain sockets.
3
Analyze the chemistry replenishment for insufficient amounts per the check sequence listed in
TROUBLESHOOTING GUIDE SECTION 1 - REPLENISHER PUMP PROBLEMS provided on
