TIP:

If the substrate is telescoped on the input roll, there is a risk of substrate jams and damage to the

printheads. Try to straighten the edges of the substrate to minimize telescoping on the input roll before
loading it into the printer.

TIP:

Check that the substrate is attached to the input core.

The roll is now ready to be loaded into the printer.

TIP:

If you are a regular user of different substrate types, you can change rolls more quickly if you preload

rolls of different substrate types on different spindles. Extra spindles are available for purchase.

Dual-roll printing

You can print on two rolls at the same time by using the dual-roll spindle.

Loading the dual-roll spindle

1.

Insert the first roll on the spindle.

2.

Insert the second roll on the spindle.

3.

Center both rolls, using the marks on both sides of the center of the spindle. The input and output rolls
should be positioned identically on their respective parts of the spindle.

4.

Inflate the valves at both ends.

Use the Dual Roll Center Support to ensure that no part of the substrate path suffers from an excess of
tension due to the weight of the substrate. When the weight of the substrate is high, the absence of this
accessory could increase the risk of a printhead crash, which decreases printhead life as well as spoiling the
current print. The Dual Roll Center Support needs to be calibrated; see the dual roll guide, which you can find
at
