2.2.3.2 Roll Paper Feeding
When selecting the Roll Paper Mode, the contol Panel switches function in
different ways from when printing other than roll paper. This section describes
the deifference.
1. The roll peper is fed into the printer after a lapse of three seconds from
when the PE sensor detects the paper.
2. The roll paper is fed backward to be set at the print position.
While the printer is performing the above operation, the switches are disabled.
After the roll peper is set to the print position, the switches operation becomes
defferent from when printing other than roll paper.
The details of the difference are described below.
†
When Loading Roll Paper.
Pressing the Roll Paper Switch for more than 3 seconds feeds the leading
edge of the roll paper backward to the PE Sensor (the Paper LED flashes).
In this state, draw the roll paper and press the Paper Switch to return the
panel operation to the normal mode that enables paper feeding from the
ASF.
†
When Received a Print Job for Roll Paper
1. After finished the print job, press the Roll Paper Switch.
2. A cutoff line is printed, and the roll paper is fed to the roll paper cut
position.
3. After cutting the roll paper with a pair of scissors or like, press the
Roll Paper Switch again. This returns the leading edge of the
paper to the print starting position.
