Error Processing
The machine supports Page Continuation Action error processing. See Intelligent Printer Data Stream
Reference for details.
The printer stops if there is a probability that it is not parsing commands correctly.
This means that, regardless of the setting of the Exception Handling Control (EHC) the printer will stop
processing, send a NACK, and enter home state immediately if one of the following conditions occurs:
1. The command length is less than 5 (No correlation number present).
2. The command length is less than 7 (Correlation number present).
3. The command length is greater than 32767.
4. The command does not have X’D6’ as the first byte of the command code.
5. The command does have X’D6’ as the first byte but is otherwise unrecognized.
6. A resource download is interrupted, resulting in a purge of the partial resource object.
The maximum numbers of queued asynchronous and synchronous errors are as followed.
• One for ARCTIC and NDS DSC mode
• Seven for NDS LU1 mode
• Seven for TCP/IP mode
Intervention required and equipment check exception types will be reported for NDS and TCP/IP
interface type.
Exception Highlight Support
If a position exception occurs and the "position-check highlight" flag (XOAEHC byte 2, bit 6) is on
(B’1’), or if a Page Continuation Action (PCA) is taken for a position check, the approximate location of
each unique occurrence of the position check will be highlighted with a Print-Error-Marker (PEM). Other
exceptions detected in page state, or a derivative of page state, or when printing a medium overlay,
which have a PCA defined, are also indicated by a PEM when the PCA is taken.
A PEM is a distinguishing mark which is placed in close proximity to the area on the page where the
exception has occurred.
• The PEM for Position Check processing is a solid rectangular mark, placed in close proximity to the
area on the page where the exception occurred. For the exception detected, the associated code
(08C100) will be located at the top of the logical page, starting in the left hand corner.
• The PEM for PCA processing is a hollow rectangular mark enclosing a +, placed in close proximity
to the area on the page where the exception has occurred, if the location can be accurately
specified. For the exception detected, the associated code (040B00) will be located at the top of
the logical page, starting in the left hand corner.
