37,0XX.xx Errors - PEST Faults

AC power supplied by power sources such as uninterruptible power supplies (UPS's)
or DC-to-AC inverter systems, may not supply enough current to properly power up
the printer. In these cases, the printer may report printhead jet-stack or reservoir
heater disconnect, drum heater, or preheater errors (37,002.47 thru 37,012.48). Verify
the AC power source prior to troubleshooting a printer exhibiting any of these errors.
For wiring diagrams to aid in diagnosing PEST faults, see "Wiring Diagrams" on
page 10-1.
