Roll switching policy
If the printer has two rolls of paper and it receives a job that could be printed on either roll, it will
normally print on the currently loaded roll because there is no reason to change.
However, if the current roll is much wider than the job requires, to print on the current roll will mean
some waste of paper. If the other roll is narrower, but wide enough for the job, then paper can be
saved by printing the job on the other roll.
In these circumstances, the roll switching policy determines whether the printer changes to the
narrower roll or continues to print on the wider roll.
To set the roll switching policy at the printer's front panel, select the icon, then Paper handling
options > Roll switching options. There are two options:
● Minimize paper waste means that, in the above circumstances, the printer will change to the
narrower roll.
● Minimize roll changes means that, in the above circumstances, the printer will continue to print
on the current roll.
Unattended printing
The HP Designjet 4500 Printer series, with multiple rolls and optional stacker, plus robust and
consistent image quality, is perfect for long unattended printing jobs.
Here are some recommendations to help you deal with a long queue of printing jobs.
● If feasible, use brand-new long rolls of paper.
● If you want to print on partly-used rolls, you can check the paper type and the remaining length
in the Embedded Web Server or in the front panel, to confirm that you have enough paper to
print all your jobs.
NOTE Information on the remaining length is available only if you told the printer the
length of the roll when you loaded it.
● Check that you have paper wide enough to print all of your jobs (any jobs that are too wide will
be put “on hold for paper”).
● Check the ink levels remaining in your ink cartridges.
● The standard bin is recommended only for less than 30 separate prints. The stacker can handle
up to 200 prints.
● When you have submitted your print jobs, you can use the Embedded Web Server from a
remote location to monitor their status.
● Drop detection should be set to Intensive.
● Drying time should be set to Optimized.
● We recommend the following settings, depending on the paper type and what kind of prints you
are making.
