7 Working with two rolls (T1500 series)
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 (T1500 series) on page 75 .
When working with multiple rolls, bear in mind that a protected roll is protected from use unless the roll
number or its paper type are specifically requested. See Roll protection (T1500 series) on page 75 .
The current status of both rolls is shown on the front panel if you press , then if it is not already
highlighted.
NOTE: When you print from a USB flash drive, multiroll printing is considerably simplified: either you
specify manually which roll you want to use, or you can select Save paper, in which case the printer chooses
the narrowest roll on which the print will fit. You cannot specify the paper type.
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 (T1500 series) on page 23 .
● 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 23 .
The printer driver for Windows will tell you which paper types and widths are currently loaded in the printer,
and on which rolls.
Here are some settings that may be used in typical situations.
NOTE: The Type is and Source is settings are in the printer driver and the Embedded Web Server; the Roll
switching policy is set in the front panel.
