Note
Always set the drive side and keep it set as the base.
When changing film, remove the end plate on the con-
trol side of the shaft. The new roll should then be
pushed tight up to the plate on the drive side and the
shaft should be slid over and engaged in the drive.
Suggested leaders:
•
For vinyl: 65" (165.1 cm)
•
For paper: 75" (190.5 cm)
To advance the paper without the vinyl:
You may want to advance the paper without the vinyl
for several reasons:
•
At the beginning of a new roll to clear the splice
and reduce leader waste.
•
To get past a large white spot, a known extra, or a
bad image on a roll of images.
The key to advancing the paper without the vinyl is to
raise the main roll but let the material continue to run
through until the paper that is not stuck to the vinyl
clears the paper peal idler. Then, put the machine in
reverse briefly to release tension on the paper peal
idler, or release the pull roll clutch and turn it back by
hand. Lower the paper unwind and rewind tension and
hand turn the paper roll so that the paper is advanced
without the vinyl advancing.

To advance the vinyl without the paper:
Release all the tension on the transfer media web. Start
the vinyl web. If the paper is not stuck to the vinyl,
only the vinyl web will advance.

On machines without the preheater option it is possible
to splice the two materials together using the bottom
main roll as the firm, straight taping surface.
To splice paper:
Splicing paper is also the recommended way to change
over to new material. The key to a successful splice is
to leave enough of the old paper to be able to wrap it on
the new roll and tape it on a square, firm surface.
1. Load the new roll of transfer paper on the machine.

rial over the old so that, when the paper is peeled
off later, the new paper is lifted along with it and
does not pull the tape off.
