Failures

Description:
The power LED is lit, but the printer has one of the following
faults:
- The printer refuses to start up.
- The program execution is halted.
- Stepper motors do not work.
Possible Causes and Suggested Remedies:
• Flash or DRAM SIMMs not properly fitted.
- A SIMM is not fully inserted in its socket. Remove all SIMMs
and fit them back again, making sure they are being firmly held
by the snap-locks.
• No Boot Flash SIMM in socket ROM2.
- A Flash SIMM containing a boot sector must be fitted in socket
ROM2, or the printer will not start.
• Startup error.
- Execution of the initial boot sequence can be checked as
described in chapter 15.6. If the execution stops prematurely,
note when it happens and contact our Technical Product
Support dept.
