Possible Solution(s)
Possible low or fluctuating AC line
voltage; try moving the printer to
another circuit. Other causes can
include a faulty Power Supply PCB,
Main Logic PCB, or printhead.
If the condition persists, possible
faulty Main Logic PCB (see Section
4.4).
Wait. Allow the printhead to cool
before resuming operation. If the
condition persists, verify that
environmental conditions are within
specification for the printer.
Possible Solution(s)
Cycle power OFF and ON. If the
fault does not clear, adjust the +24
VDC supply voltage or replace the
Power Supply PCB; see Section 4.5.
WARNING! Use extreme
caution when measuring voltages.
Cycle power OFF and ON. If the
fault does not clear, replace the
Main Logic PCB; see Section 4.4.
