Protect a paper type
You can protect selected paper types to avoid printing on them unintentionally. A protected paper type will be
printed on only when the paper type is explicitly specied in the job.
To protect a paper type, go to the front panel and tap , then Job management > Roll policies > Protected
paper types, then select the paper type that you want to protect.
When a paper type is protected, the icon appears before the paper name.
To print on a protected paper category, just select the paper type explicitly when submitting the job from a
printer driver or other job submission software.
NOTE: If a protected paper type is not explicitly selected, and no other paper types are available, an out-of-
paper message will appear.
Unattended printing/overnight printing
The printer is well suited to long, unattended print jobs, having multiple rolls plus robust and consistent image
quality.
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 conrm 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, or if the printer read the length of the roll from the barcode printed on it.
● Load two rolls of paper suitable for your jobs. If the printer nishes one roll, it will automatically switch to
the other.
● HP recommends the use of papers approved for your printer. See Accessories on page 140.
● Check that you have paper wide enough to print all of your jobs. Any jobs that are too wide may be put on
hold for paper if the paper mismatch action is set to Pause and ask (see Solve paper mismatch
on page 82).
● Check the ink levels remaining in your ink cartridges.
● When you have submitted your print jobs, you can use the Embedded Web Server from a remote location
to monitor their status.
● Drying time should be set to Optimal.
● Tap , then Job management > Roll policies > Use most depleted roll > On.
We recommend the following settings, depending on the paper type and what kind of prints you are making.
