Log Message
Processor failed to
warm up when heater
turned on
There are three primary causes for this error:
1. The processor-measured temperature has not locked into ±0.15 °C of the
set point for at least 20 seconds before the end of the warm-up time allotted.
The processor electronics have failed. For this case, the allotted time for
warm-up will expire. (Resolution: Replace the board.)
2. There was a failure to heat or the warm-up rate was too slow (=/< 3 °C per
minute). For this case, the failed SSR status bit should be set. Either the
solid-state relay (SSR) or mechanical power relay has failed. (Resolution:
Replace the board.)
3. The environment may be too cold or the power source underrated.
(Resolution: Repeat the warm-up cycle.)
• The allotted time is calculated from the initial processor drum temperature.
• The error clears only when imager power is cycled.
The imager can only print jobs that were in process when the error occurred.
The spooler can still accept jobs, but the jobs will not print until the error is
resolved. All jobs that were in process when the error occurred will reprint
completely when the error is resolved. [SI-1]
1. Shut down the laser imager, then restart the laser imager.
2. If the error persists, call for service.
