HP Designjet T920 ePrinter series - Manual (Page 83)

● Leave the printer permanently turned on so that it can maintain the printhead in good condition
automatically. This regular printhead maintenance uses a small amount of ink. However, if it is not
done, the printer may need to use much more ink later to restore the health of the printhead.
● Wide prints make more efficient use of ink than narrow prints, because printhead maintenance uses
some ink, and its frequency is related to the number of passes made by the printhead. Therefore,
nesting jobs can save ink as well as saving paper (see Nest jobs to save roll paper (T1500 series)
on page 73 ).
Roll protection (T1500 series)
If you choose to protect a roll, jobs will be printed on it only if the job explicitly specifies the roll number or
the paper type loaded on the roll. This may be useful, for example, in the following cases.
● To stop people from accidentally printing unimportant jobs on expensive paper.
● To avoid printing on a particular roll when printing from AutoCAD without interacting with the HP printer
driver.
To protect a roll, go to the front panel and press , then , then Setup > Printing preferences >
Paper options > Roll protection.
NOTE: If you protect a roll, then later unload the current roll and load a new one, the new roll remains
protected. You are protecting the roll number, not one specific roll of paper. That roll number will remain
protected until you cancel the protection.
TIP: If you print without specifying a roll number or paper type, you will not be able to print on any
protected roll.
Unattended printing/overnight printing (T1500 series)
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.
● Empty the stacker.
● 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, 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 finishes one roll, it will automatically switch
to the other.
● 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 Put job on hold (see Paper mismatch action
on page 23 ).
● 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.
