correct the problem.
SCALE INOPERATIVE/BLANK DISPLAYS
1. Check AC power at outlet.
2. Check Voltage on Main Logic PCB. If voltages are zero, check Power Supply.
3. If test point voltage is good replace Main Logic PCB.
4. Check Display Cable on Main Logic PCB and Operator Display PCB. Check
Display PCB.
KEYBOARD INOPERATIVE
1. Check keyboard connection on keyboard controller PCB.
2. Check Keyboard controller connection to Main Logic,
ensure all connections are secure.
3. If all connections are secure and keyboard is inoperative:
a) Replace keyboard controller PCB.
b) Check keyboard once again.
c) If Keyboard is still inoperative, replace keyboard.
SCALE WON'T ZERO (DISPLAY "PUT PLATTER ON" or "ZERO NOT CAPTURE")
1. Check platter and spider for obstructions. Turn power off, then back on.
2. Recalibrate.
3. Check Load Cell supply voltage.
4. Replace Load Cell.
LOSING PROGRAMMED DATA
1. Check Error Report of Service Mode.
2. Check Main Logic voltage at test points.
3. Replace Main Logic PCB.
PRINTER WON'T DELIVER LABEL
1. Check printer for obstructions.
2. Check if there is a label which has not been removed.
3. Check Take Label sensor obstructions.
4. Clean Take Label sensor.
5. Test Take label sensor with SENSOR TEST in Service Mode.
6. Check harness from Printer to Main PCB.
7. Check label stepper motor.
8. Replace Main Logic PCB.
INCORRECTLY INDEXES LABELS
