– Use most depleted roll (Z6dr/Z9
+
dr only): When there are two or more rolls with the same paper type
and width, the roll selected is the roll with less paper.
– Paper type protection (Z6dr/Z9
+
dr only): You can avoid printing accidentally on special paper types by
protecting them. Protected types are eligible for printing only when paper type or roll are specied in
the job.
See also Protect a paper type on page 73.
Solve paper mismatch
If the paper currently loaded in the printer is not suitable for a particular job or page, the printer can
automatically solve the conict or give a number of choices depending on the printer policies. Such a conict may
be caused by a job sent to the printer with no specic roll or paper type assigned to it, or by a roll coming to its
end during printing. The following options are available in the paper mismatch settings menu; you can reach this
menu from the job queue by tapping , then , then Mismatch actions > Paper mismatch; or by tapping
, then Job management > Mismatch actions > Paper mismatch.
● Pause and ask (the most restrictive option): Printing stops until the correct paper is loaded. This option is
recommended when the printer is attended. A message appears, asking what you want to do: cancel the
job, print anyway, put on hold, or load paper. These options are also available in the job queue.
● Hold job and continue with next: Put mismatched jobs on hold until the correct paper is loaded, and
continue printing the rest of the job queue. The printer sends an alert whenever a job is put on hold. This
option is recommended when the printer is unattended, even though the integrity of a job may be
disrupted, to avoid stopping the queue. Once the paper required for the job is loaded, the job or pages are
automatically resumed.
● Print anyway (the least restrictive option): Print on whatever paper is loaded. The printer will choose the roll
to print according to the following criteria: rst where the page ts and then the same paper type. This
option will never select a paper type that has been protected.
Solve output mismatch
The selected output for a particular job is not available for some reason: output disconnected, detached, full, not
empty for a job that requires it to be empty, or size/type/length not supported by that output. The following
options are available in the paper mismatch settings menu; you can reach this menu by tapping , then
