HP Designjet 4520 Printer series - Manual (Page 189)

NOTE: To see the job queue at the front panel, select the icon and then Job queue.
Based on a set of criteria that you can set when sending a job, the HP Designjet 4520 will decide which
of the rolls of paper loaded in the printer is more suitable to print the job. If there is no roll of paper
available that meets all the conditions set previously, the HP Designjet 4520 will then put the job on hold
for paper. You can manually resume the job and forces it to print on a paper different from the one that
was set when the job was sent, otherwise it will stay on hold.
Which criteria are used to decide to which roll a job will be printed?
When a user sends a job, the paper type that is desired can be set (in the driver or in the Embedded
Web Server). The printer will print this job on a roll of paper of the chosen paper type and one that is
wide enough to print the drawing without clipping. In case there is more than one roll where the job could
be printed meeting all the criteria, the roll will be chosen according to your preferences. These can be
set by using a setting in the printer’s Front Panel: Paper Menu > Paper handling options > Roll
switching options which has two possible values:
● Minimize paper waste. If this option is chosen, the printer will choose the narrowest roll that meets
all the criteria, to avoid wasting paper due to trimming.
● Minimize roll change. If this option is chosen, the printer will choose the roll that is currently loaded
on the print platen, to avoid wasting time with a roll switch.
The default option is Minimize paper.
When is a job put on hold for paper?
A job is put on hold for paper in the following cases:
● The paper type that has been selected by the user is not currently loaded on the printer.
● The paper type that has been selected by the user is loaded on the printer, but the drawing is too
wide to fit on any of the rolls of this paper type without clipping.
If I load a new roll of paper, will jobs that were on hold for paper be
automatically printed?
Yes. Since firmware 8.1.1.3, every time a new roll of paper is loaded, the printer will check if there are
any jobs on hold for paper that could be printed on the loaded roll. In case the answer is yes, the printer
will ask if these jobs should be automatically resumed with the following message:
● Would you like to print the jobs that are on hold for paper? Yes/No
I don’t like jobs being put on hold for paper. Can I prevent it?
Yes, this can be done from the front panel: select the icon and then Job management options >
Enable on hold for paper. There are two options:
● When needed (default value). Jobs are put on hold for paper when there is no paper loaded on
the printer that meets the necessary conditions: correct paper type and correct paper size.
● Never. Jobs are never put on hold for paper. If there is no paper loaded that meets all the conditions
set by the user, the job is printed on whichever roll seems most suitable for it.
I set the option “Enable on hold for paper” to Never, but some jobs are still
put on hold
If the Show print preview option is selected in the driver or the Embedded Web Server, jobs are put
on hold until you have checked the preview and resumed the job. Check that the Show print preview
