RIBBON LATCH NOT ENGAGED
The ribbon pinch roller in the thermal printer is not in place against the
ribbon drive roller.
RIBBON NOT DETECTED
The thermal printer ribbon optic detected that the ribbon roll is empty or
the ribbon is torn.
SECURITY FUSE VIOLATION
The device security fuse has been programmed. A load, program, or
verify operation will give this error.
SUMCHECK ERROR
The data sumcheck calculated by the 2500 during the file download did
not match the sumcheck written in the data file. This problem could be
caused by an incorrect device selection.
UNABLE TO LOWER BEAM
The beam will not move down, or the beam is lowering and the beam
down optic is not operating correctly.
Run the Optics diagnostic test to check the beam down optic. Clean,
adjust or replace the optics based on the test results.
Low air pressure may be too low. Confirm that it is set to 40 PSI.
Ensure that no object is blocking the beam’s complete vertical movement.
Ensure that the beam up solenoid (4) and cutoff solenoid (3) are
functioning properly.
UNABLE TO PICK UP DEVICE,
PRESS START
Vacuum is not being achieved.
High air pressure may be too low. Confirm that it is set to 75 PSI.
The device is not positioned on the chuck properly. Check the track
width adjustment and the beam alignment to the device.
The chuck you are using may be dirty or may not be the correct type for
the device package. Check the chuck and replace it with the correct one.
Clean or replace the chuck tip.
The vacuum generator may not be operating correctly; it may be leaking,
or its filter may be clogged. Run the Optic diagnostics test to check its
operation.
The vacuum switch or the circuitry on the controller board (or connector)
may be faulty. Check the LED on solenoid 7. Check the 24V supply used
for the vacuum generator solenoid on the controller board at J1.
The solenoid for the vacuum generator may not be operating correctly.
Check the Solenoid diagnostics test.
The chuck or vacuum line may be leaking.
UNABLE TO RAISE BEAM
The beam will not move up. Check optic tests and run solenoid test 4.
Low air pressure may be too low. Confirm that it is set to 40 PSI.
Check to see if an object is blocking the beam’s vertical movement.
Lubricate the beam shafts.

ProMaster 2500 User Manual 6-5
Check to see if the beam up solenoid (4) is functioning properly. Check
the red LED on the solenoid itself (see Figure 5-16) to see if it turns on
during the test. Use a small hex wrench to depress the manual test button
on the side of the solenoid to see if the beam rises. If it does not move up,
check the air pressure or check for leaks in the air line. Replace the
solenoid if necessary.
UNABLE TO RELEASE DEVICE,
PRESS START
Low air pressure may be too low. Confirm that it is set to 40 PSI.
Check the blow off solenoid diagnostic test (test number 5).
Vacuum does not shut off. Check S7 solenoid LED on handler controller
board while running the solenoid test.
Check the vacuum generator solenoid (7) to see if the LED goes on and off
when the test is run.
VERIFY FAIL, PASS X
Low (pass 1) or high (pass 2) verify of the data in RAM with the data in
the device has failed to match.
