Spindle supports on which to rest the spindle when it is not in use Requirements Before using the Dual Roll Kit with an HP Designjet L65500 printer, you must check that the printer's firmware and HP Internal Print Server software are up to date.
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. Loading the dual-roll spindles Ensure that the differential hubs on the input and output spindles are aligned with each other. Chapter 2 Use of the dual-roll spindle ENWW...

When both differential hubs are correctly positioned, use an Allen key 6 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.

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.
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.

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.

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.

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.

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.
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 spindle. This could mean that you have reached the end of the roll, or the spindle is not correctly inflated, or the dual-roll differential hub is locked.

Changes to roll loading and unloading After installing the new firmware and software, you must go to the HP Internal Print Server and select Substrate > Load/Unload in order to load or unload substrate, instead of using the front panel as before.
