The following error codes should not occur, but if they
do, they indicate one of the following:
• 5256 planar failure
• Transmission errors
• S/34 microcode failure
Error codes 21 and 25 indicate that the controller
received status bits from the 5256 that are not used by
the 5256. Errors 47 and 48 indicate 'forms stop' or
'forms position check' from the printer with the ' unit not
available' bit off (Ready). Error 49 results if the printer
indicates outstanding status in poll response frame 1,
but the response to the 'read status' command showed
none. Error 32 indicates a hard, slow speed Ciheck
without another print mechanism error.
