Action Codes in Sense Byte 2
The action codes in sense byte 2 classify the exception to assist host-exception recovery and allow
printing to continue. The action codes listed are the only ones returned by the printer.
Action Code (in hex) Exception-Recovery Action
01 Data Stream Exception A syntax error exists in the IPDS data stream. The specific recovery
actions depend on the specific exception (sense bytes 0, 1, and 19 in
the tables of printer exception codes) and host support requirements.
Data stream exceptions occur on the page or resource just before the
received page counter.
08 Paper Jam The printer detects a paper jam. Retransmit all pages and associated
resources (overlays, page segments, and fonts) that have not passed
the printer-defined jam recovery point.
