Printing System Guide5-2 Common Controller• If FIFO is desired dynamically, all jobs must be submittedfrom a single client to a single queue with a release status setto [Yes]. All other queues must have the release status set toNo.• If the queue that is set to use FIFO is not currently releasingjobs to the printer, then the jobs may not appear in the correctFIFO order. Select [Job Manager] and then select theOptions menu. Select [Redisplay] to view the jobs in correctFIFO order.NOTE: Some error conditions within the printer can cause a jobto fault because there is no recovery operation that the operatorcan perform. These jobs are dropped out of the sequence,destroying the original FIFO order. The controller is not designedto wait for corrective action by an operator for a faulted jobbefore advancing to the next job which has already beenscheduled and is displaying a ‘Waiting for Printer’ status.Enable/Disable FIFO Job SchedulingTo enable or disable FIFO job scheduling, perform the following:1.
