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; please refer to the dual roll guide, which
you can find at
http://www.hp.com/go/latex3000/manuals/.
Load a roll into the printer
The objective when loading substrate is to get a uniform tension across its width and length to minimize the
risk of skew, wrinkles, and telescoping. There are four ways in which the substrate can pass through the
printer:
●
Roll-to-roll configuration
●
Dual roll-to-roll configuration
●
Roll-to-free-fall configuration
●
Roll-to-collector configuration
