The Procedures
69
Power on “hang” condition
1. Remove the paper path or pedestal top cover. Check all cable
connections to the CMX controller board and the power supply board.
Connect cables.
2. Power up the printer.
If the printer “hangs,” replace the CMX controller board.
3. Power up the printer.
If the printer “hangs,” replace the power supply board.
POWER SAVER MODE Message
1. This is a status message. The printer is in low–energy idle state, all fans
and higher voltages are off, only +5Vdc logic circuits are active.
No action required, but you can press the PAPER ADVANCE key to
revive the printer from power saver mode.
POWER SUPPLY HOT Message
NOTE: The printer has sensor circuits that sample the operating temperature
of key components of the power supply. When higher than normal
temperatures are sensed, print speed is automatically reduced. If the
printer runs at reduced speed for an extended period of time, the
POWER SUPPLY HOT message is sent to the LCD and printing
stops, allowing printer components to cool down. Pressing the
CLEAR key resumes the print task. Check the operating
environment. A severe environment is one with an ambient
temperature at or above 40° Celsius (104° Fahrenheit) or is dirty
enough to create blockage of the cabinet fan vents. The printer must
never be run at ambient temperatures greater than 40° Celsius (104°
Fahrenheit). If the printer is located in such an environment, relocate
it to a cooler, cleaner area.
1. Inspect printer environment for severity. (See NOTE above.)
Advise the user to move the printer to cooler, cleaner location.
2. Check the kinds of print jobs the user is running: look for very dense
graphics and layouts.
Advise the user to run jobs in smaller batches.
3. Power off the printer. Remove the paper path or pedestal top cover.
Check that the power supply guard/air deflector is correctly positioned
over the power supply board. WARNING:
DO NOT TOUCH THE
POWER SUPPLY, but hold your hand close enough to check for heat
radiating off the power supply board.
If the power supply is noticeably hot, replace it.
4. Check that all fan cables are connected.
Connect all fan cables.
