Product		Kodak^® Lotem^® 400 Quantum platesetter

Error		`Drum is in error state`

Symptoms		When a job is sent to a Lotem 400 Quantum platesetter, the platesetter stops operating because the data transfer times out, and an error message appears.

Solution		To resolve this problem, perform the following series of checks: Run diagnostics. Check the wiring that controls the drum-command paths. Verify that the Inhibit LED is always on when the drum driver error appears. Verify that drum movment is not obstructed. Check whether the head grippers are pressed against the rollers. If they are, lower the value of the IO OBJECTS\Loading System\Drum\Unload Gripper Actuator To Unload Tray (mm) parameter to 250. Reload the defaut NVS and Flash files on TMCE. Replace the drum driver and D-box.
