Substrate issues If the roll is not firmly attached to the input core, proceed as follows. 1. Unload the roll from the input spindle and load it onto the output spindle. Take care to avoid telescoping. 2. Raise the pinches and, in the front panel's Substrate Management menu, raise the carriage beam to its maximum height. 3. Unload substrate from the roll and pass it backwards through the printer towards the input spindle. Attach it to the empty core on the input spindle, securing it with adhesive tape. Wrap a couple of turns of substrate around the input core. Take care to align the substrate with the output roll. 4. Lower the pinches. 5. Go to the HP Internal Print Server and select Substrate > Load/Unload, then select the printer configuration and press Load. NOTE: If the substrate check fails, return the roll to the input side and attach it to an empty core on the output side. Raise the pinches and use the front panel's Substrate Management menu to move all the substrate onto the output core. 6. Select the correct substrate in the HP Internal Print Server. 7. Press the Move substrate key on the front panel, then the Back key, and wait until all the roll has been wound onto the input spindle. 8. You may decide to cancel rewinding when the substrate is detached from the output roll. Then attach it to the output core to print immediately, or rewind it completely onto the input core if you want to remove the roll. The core slips on the Spindle (Dual Roll) If the core slips on the Dual Roll, you can adjust the rubber rings (A) on the Spindle holders to a larger diameter (B), so that the core is held more firmly onto the spindle. Do not forget to place them back afterwards as this may cause an issue when installing another core later. ENWW The core slips on the Spindle (Dual Roll) 51

The core slips on the Spindle (Dual Roll)
If the core slips on the Dual Roll, you can adjust the rubber rings (A) on the Spindle holders to a larger
diameter (B), so that the core is held more firmly onto the spindle. Do not forget to place them back
afterwards as this may cause an issue when installing another core later.
