Substrate issues

3.If feasible, manually move the carriage slowly and carefully to the side, away from the substrate. If this is not feasible because of the severity of the jam, try raising the carriage beam to its maximum height.

4.Remove all substrate and pieces of substrate from the printing zone and from any other parts of the printer into which they may have fallen. Check the curing zone in particular. If you are unable to remove them all, please call your service representative (see HP Customer Care Centers

on page 49).

5.Before restarting the printer and reloading the substrate, check that all circuit breakers are on and all emergency stop buttons released.

The substrate is not attached to the input core

If the roll is not firmly attached to the input core, you may see banding on your prints, or the printer may report the end of the roll. To correct the problem, 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.At the front panel, exit the Substrate Management menu, replying “Yes” when asked about checking the substrate.

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 Form Feed 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.
