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.
