If nesting is turned on, the prioritized job may still be nested with others. If you want this job to be printed next,
without waiting to nish the nesting countdown, click the Start print button in the nesting section.
In the following cases, the Next print button is not displayed:
● The job is already at the front of the queue.
● The job is on hold—in this case the Resume printing button is displayed instead.
● The job has nished—in this case the Reprint button is displayed instead.
● The job has some error condition.
Delete a job from the queue
Under normal circumstances, there is no need to delete a job from the queue after printing it, as it will just fall o
the end of the queue as more les are sent. However, if you have sent a le in error, and want to avoid printing it,
you can simply select the job and then click Delete.
In the same way, you can delete a job that has not been printed yet.
If the job is currently being printed (its status is printing), you can click Cancel and then Delete.
Reprint a job in the queue
To reprint an already-printed job, select the job from the queue, then click Reprint. When reprinting a print job,
you cannot change the print settings, because the job has already been rasterized.
Job status messages
These are the possible job status messages, approximately in the order in which they may be seen:
● Downloading: The printer is receiving the job from the computer.
● Processing: The printer is parsing and rendering the job.
● Waiting to print: The job is waiting for the print engine to become free to proceed with printing.
● Nested: The printer is set up with Nesting=On and is waiting for other jobs in order to complete the nest and
proceed with printing.
● Preparing to print: The printer is performing writing system checks before printing the job.
● On hold for preview: The job was sent with the on hold for preview option.
NOTE: If the printer hangs up while printing a job, and the queue facility is turned on, the partially printed
job will appear in the queue as on hold when the printer is next turned on. When you resume the job, it will
start printing at the page at which it was interrupted.
● On hold for paper: The job cannot be printed because the right paper is not loaded in the printer. Load the
required paper, see Paper handling on page 25, and click Continue to resume the job.
● On hold for accounting: The job cannot be printed because the printer requires all jobs to have an account
ID: enter the account ID and then click Continue to resume the job.
TIP: To set an account ID, see Require account ID on page 21.
