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 (cabinet
model) or electronics barrier panel (pedestal model).
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. Power on the printer. Download the emulation (page 194).
If the download fails, replace controller.
