19.3 Intervention required (IRQ)
The Xerox 4500 PS TR supports IRQ - Intervention Required. When the
intervention required status message is sent, the print session will be
responsible for the recovery action.
To control the printer error conditions, two separate IRQ timers are
available:
- IRQ timeout
Used to report printer error / fault conditions to the initiating application
- Hold timeout
Used to report printer hold conditions to the initiating application.
The Xerox 4500 PS TR handles the following intervention status conditions:
• Online/Offline - i.e. is the printer Ready?
The IRQ conditions vary, however, depending on the print session. For a
description of the differences, see below.
IPDS
Ready?
1) Intervention conditions that can be reported
presently will be supported.
2) The HOLD timeout parameter is used to
determine when hold conditions are reported to
the host.
ICDS
Ready?
1) The intervention condition is reported to the
host. The user is required to perform
intervention recovery (i.e. attend to the printer
problem). Once the printer is Online,
printing will restart from the last checkpoint.
2) The HOLD timeout parameter is used to
determine when hold conditions are reported
to the host.
LPD
Ready?
1) There will be no response or notification with
any intervention condition, i.e. the print data
remains pending in the printer (printer appears
busy).
2) The HOLD timeout parameter is used to
determine when hold conditions are reported to
the host.
