The uses of a multiroll printer
A multiroll printer can be useful in several different ways:
● The printer can automatically switch between different paper types according to your needs.
● The printer can automatically switch between different paper widths according to your needs.
This enables you to save paper by printing smaller images on narrower paper.
● If you load two identical rolls into the printer, you can leave it printing unattended for a long time,
because it can switch from one roll to the other automatically when the first is exhausted. See
Unattended printing/overnight printing (T1200 series only) on page 63 .
There are two concepts to help you when working with multiple rolls.
● The active roll is the roll that is currently loaded and will be printed on by default unless the
printer has some reason to switch rolls. To change the active roll, select the Paper menu icon
, then Select active roll.
● A protected roll is protected from use unless the roll number or its paper type are specifically
requested. See
Roll protection (T1200 series only) on page 62 .
The current status of both rolls is shown on the front panel's status screen.
How the printer allocates jobs to paper rolls
When you submit a print job from the Embedded Web Server or the printer driver, you can specify
(using the Paper type or Type is option) that you want it to be printed on a particular paper type; you
can even specify (using the Paper source, Source is or Paper Feed option) that you want it to be
printed on a particular roll (1 or 2). The printer will try to satisfy these requirements, and it will also
look for a paper roll large enough to print the image without clipping.
● If both rolls are suitable for the job, the roll will be chosen according to the roll switching policy.
See
Roll switching options on page 21 .
● If just one of the rolls is suitable for the job, it will be printed on that roll.
● If neither roll is suitable for the job, it will be held in the job queue with the status “On hold for
paper”, or printed on an unsuitable roll, depending on the paper mismatch action. See
Paper
mismatch action on page 21 .
The printer driver for Windows will tell you which paper types and widths are currently loaded in the
printer, and on which rolls.
