Chapter 17 — Troubleshooting
17.4 CPU Board Failures
Description:
The power LED is lit, but the printer has one of the following faults:
• The printer refuses to start.
• The program execution is halted.
• The stepper motor does not work.
• At startup, the message “Starting” is displayed followed by the message
“Timed Out.”
Possible Causes and Suggested Remedies:
• Flash or SDRAM SIMMs not properly fi tted.
- A SIMM is not fully inserted in its socket. Remove all SIMMs and fi t
them back again, making sure they are being fi rmly held by the snap-
locks.
• No Boot Flash SIMM in socket J20.
- A Flash SIMM containing a boot sector must be fi tted in socket J20,
or the printer will not start.
• Fluttering voltages.
- Check voltages on the CPU board test points, see Chapter 13.4.
If a voltage fl utters with an interval of approximately one second,
there may be a short-circuit on the CPU board. If a voltage is miss-
ing, there is probably an error in the power supply unit or the driver
board, see Chapters 17.5 and 17.6.
• Startup error.
- Execution of the initial boot sequence can be checked as described in
Chapter 15.5. If the execution stops prematurely, try changing to a
Flash SIMM that works in another printer. If that does not help, note
where the startup sequence is halted and contact Intermec’s Printer
Product Support dept.
- If there is no reaction neither on the display nor on the serial channel,
there is a major error on the CPU board. Check the Flash and
SDRAM SIMMs by installing them in another printer. Inspect the
CPU board visually in the area of the processor (U13) and the sup-
port chip (U30). If no obvious fault is detected, replace the CPU
board.
