3. Note the position of the end of the roll on the scale marked at the geared end of the spindle. Its position should be not less than 3.2 cm (1.25 in) on that scale, otherwise the substrate may go out of the print zone and start touching the printer covers. The input and output rolls should be positioned identically on their respective spindles. Handle the substrate TIP: When loading heavy rolls of non-elastic substrates that are approximately half the spindle length, you may find it useful to load the substrate closer to the center of the spindle, to reduce the risk of skew, wrinkles and telescoping. 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.

Load a roll into the printer
The objective when loading substrate is to get a uniform tension across its width and along the
substrate path to minimize the risk of skew, wrinkles and telescoping.
The substrate roll is mounted on the rear spindle and will be collected on the front spindle. The substrate
goes from the rear spindle (1) over the main roller (2), over the platen, over the diverter and then to the
front spindle (3).
Each of the spindles has its own motor. The motors maintain tension on the substrate. Some vacuum
is applied at the level of the platen to keep the substrate flat. The substrate is moved forwards by the
drive roller motor, on which there is a pinch mechanism to stop the substrate from slipping. The pinches
