Status reporting commands
See also Status Reporting on page 69.
A status enquiry results in response ACK (6) if all sensors are clear, but NAK (15) + code if one
or more sensors report some condition.
A status enquiry command can only return one status code at a time. If there are two or more
simultaneous conditions, each condition should be cleared and the status enquiry repeated in
order to get a complete report of all status codes.
Note • All status commands are immediate, that is they pass the print queue and are
answered directly.

NAK 2 Cutter jammed
NAK 3 Out of paper
NAK 4 Printhead lifted
NAK 5 Paper-feed error. No paper detected in presenter although 10 cm has been
printed. Paper might be wound around the platen or, in some way, has been
forced above the presenter module.

NAK 0E Wrong firmware type or target for firmware loading
NAK 0F Firmware cannot start because no firmware is loaded or firmware
checksum is wrong.
NAK 10 Waste bin timed out. If the customer doesn’t take the paper and the printer
clears the presenter due to a timeout, the pending error bit is set and status
code NAK 16 is reported.
NAK FF Undefined error
Note • Errors 2, 5, and FF are terminal faults that require you to reset the printer before it will
be operable again. The printer automatically recovers from the other conditions as soon as
the cause is corrected.
