Symptom
Downloads consistently fail
Flash SIMM won't copy
Table 3. General Symptom List
Printer Operation
NOTE: Most download problems are detected by software
during the procedure and communicated by LCD
messages. If downloads fail consistently with no
messages or with erratic messages, suspect a
hardware failure.
1. Power off the printer. Remove the paper path or pedestal
top cover. Check the I/O cable connections from the host
to the printer. Check the parallel cable connection at J112
on the controller board. Inspect all cables for damaged,
bent, broken, or burnt pins. Replace any damaged cables.
Reconnect all I/O cables; make sure all connections are
clean and tight.
2. Remove the flash SIMMs. Inspect the flash SIMM sockets
on the controller board. If any socket pins are bent or
damaged, replace the controller board.
3. Check that customer has the right size SIMMs for the
emulation. (See page 189) Install SIMMs that support the
emulation software.
4. Power up the printer. Download the emulation (page 150).
If the download fails, activate the Boot Diagnostics Menu
(page 118) and run MISC UTILITIES / RUN MEMORY
TESTS. If memory fails test, replace the DRAM. If memory
tests OK, replace the flash SIMM(s).
5. Power up the printer. Download the emulation (page 150).
If the download fails, replace the controller board.
1. Power off the printer. Remove the flash SIMMs. Inspect
the flash SIMM sockets on the controller board. If any
SIMM socket pins are bent or damaged, replace the
controller board.
2. Make sure the blank SIMM is the same size as the SIMM
to be copied. Install the SIMMs, making sure they are fully
and correctly seated. Power on the printer. From the Boot
Diagnostics menu, select and run MISC UTILITIES /
COPY FLASH SIMMS. (See page 118.) If the
DESTINATION NOT DETECTED message appears, the
blank SIMM is not a type supported by the boot code on
the original SIMM. If SOURCE LARGER THAN
DESTINATION appears, the blank SIMM is not large
enough to contain the code on the original SIMM. If the
SIMM does not copy or the ERROR WRITING TO FLASH
message appears, replace the blank SIMM.
3. Power on the printer. From the Boot Diagnostics menu,
select and run MISC UTILITIES / COPY FLASH SIMMS. If
the new SIMM does not copy, replace the controller board.
