Page 6: Use Of The Dual-Roll Spindle
Use of the dual-roll spindle Load rolls onto the spindle The dual-roll spindle is marked to assist you in positioning the differential hub. NOTE: The spindle marked A is for the dimensions of the 126-in spindle. The spindle marked B is for the dimensions of the 104-in spindle. - Page 7 When both differential hubs are correctly positioned, use the Allen key to tighten the screws and secure them in place. If a differential hub is loose, the substrate could become skewed during printing. TIP: You should tighten the screw until the washer touches the bolt. If you can still see the yellow spring, tighten the screw further.
- Page 8 Insert the first roll on the spindle. Replace the hub, and secure it with the Allen key. Insert the second roll on the spindle. Replace the hub, and secure it with the Allen key. Ensure that the end of the right-hand roll is located within the maximum allowed distance from the right-hand end of the spindle: it should be between the gear and the dashed line.

Page 9: Load Rolls Into The Printer
Ensure that the roll core fits tightly on the differential hub. Load the spindle at the rear of the printer, and secure the spindle latches. Use the same process to load the output spindle at the front of the printer, but load the spindle with two empty cores to receive the printed substrate. - Page 10 If you need to raise the carriage beam, go to the front panel and select the Substrate menu then Substrate management, and press OK. Select Carriage beam position > Move to highest position. This process takes about 2 minutes to complete. The printer raises the carriage beam, making it easy to insert the substrate.
- Page 11 Open the latches at both ends of the spindle (if they were closed) and push the roll on its spindle into the printer. Close the latches to secure the spindle in place. TIP: If you cannot close the gear side latch, try sliding the spindle towards the side plate to make sure the end flange is not sitting on the bearings.
- Page 12 Once in front of the printer, if you find that you haven't unrolled enough substrate, select Start main roller motion from the front panel's Substrate menu to unroll some more. The substrate unrolls only when you pull it. Before taping the leading edges of the two substrate rolls to the empty cores on the output spindle, check by measurement that they are in the same positions on the output spindle as on the input spindle.
- Page 13 NOTE: The Move to printing (custom) position allows you to set the printhead-to-substrate distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing. Be aware that raising the printhead from the substrate may give poorer print quality. WARNING! Do not insert your hands or anything else into the printer while the carriage beam is descending.

Page 14: Troubleshooting
Troubleshooting If you see an error message numbered 78.2:01, it means that the substrate may have become detached from the rear spindle, or the core is slipping on the dual roll. This could mean that you have reached the end of the roll, or the roll is a non-standard size and is too big in diameter, or the dual-roll differential hub is locked. -
