IBM error types

XEROX MRP FAMILY COAX COMMAND REFERENCE
5.
The Xerox MRP Family coax printers support IBM error types, IBM
error code actions, and initialization errors. The printers
recognize the following error categories:
IBM data stream error type 1
•
IBM data stream error type 2
•
IBM data stream error type 3 or invalid SCS parameter
•
IBM data stream error type 4 or invalid SCS command
•
Initialization error
•
FSL error.
•
Errors are logged internally by the coax interface.
Note: Error handling in the Xerox MRP Family printers is different
N
from the IBM printers emulated. Output may differ from that
seen under similar circumstances on the IBM printer.
IBM error types are reported back to the host through the coax
protocol.
IBM error types fall into the four categories described in Table 5-
1. An error action for each error category is defined by the
system using an IBM data stream command.
These errors and their appropriate responses are handled by the
system automatically and do not require user action.
Table 5-1. Error code descriptions
Error type Description
1 Condition detected that causes loss of text
information
2 Condition detected that alters the appearance
of the printed output
3 Multibyte command detected that contains an
unsupported type or class code
4 Multibyte command detected that contains an
unsupported parameter or parameter value
SCS parameter and command errors are reported through the
coax protocols.
Although IBM errors are reported, they may not necessarily
match the errors reported by the emulated printers under certain
conditions.
