Disabled mechanisms

Some printers can function even if a mechanism, such as a paper source, becomes disabled. When the mechanism first becomes disabled and a job is sent to the printer, a PSF abend occurs, as it does for any permanent printer error. However, the operator can choose to restart PSF for a disabled printer, and the mechanism is bypassed in one of these ways:

If the duplex paper path is disabled, the printer prints in simplex.
If a paper source is disabled, paper is selected from an alternative source.
If the offset stacker is disabled, no offset stacking occurs between jobs or copy groups.

You might want to define separate print output classes to assist the operator in determining whether to restart PSF for a disabled printer. One class could be defined for print data sets that are tolerant of disabled mechanisms. This class would be defined for print-job submitters who, for example, accept simplex instead of duplex output. Another class could be defined for print data sets that are not tolerant of changes to the output caused by disabled mechanisms. If separate classes are defined in this way and a mechanism on a printer becomes disabled, the PSF operator can safely start a tolerant class of data sets on that printer and use the printer until the mechanism is enabled.

Note:

When a duplex paper path or an offset stacker mechanism is disabled, the PSF FSA must be stopped and restarted to pick up a change in the mechanisms status. If the mechanism is disabled when the FSA is started, and is then enabled by the operator, the FSA must be restarted to pick up the change in mechanism status. End of change
