☞Note
Always set the drive side and keep it set as the base. When changing film, remove the end plate on the control 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.

The recommended way to change over to new material is to splice the new material to the old and let the old material web pull the new material through the machine.
To splice vinyl:
When splicing the vinyl, stop the machine before the roll is totally used up.
1.Load a new roll of vinyl on the unwind shaft and place it on the machine. Engage the shaft into the drive tang.
2.The old material should be left long enough to lay over the new roll. This provides a straight, firm surface to splice onto.
3.Tape the new material to the old with a high quality
4.Start the tape in the center and work outward.
5.Lower the brake tension until the splice has cleared the main roll.
☞Note
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.
2.Pull the old paper around the roll of images and tension and smooth out evenly.
3.Overlap the old paper with the new paper and tape securely. It is very important to have the new mate- 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.
