HP Designjet L25500 Printer Series - The substrate has jammed

Turn off the printer at the front panel, then also switch off the power switch at the rear.

While the printer is cooling down, cut the substrate from the spindle so that it may be removed by pulling from the top of the printer. Once the printer has cooled down, unlock and open the printer window.

  caution:

If substrate is jammed on the platen or bunched up under the pinchwheels, do not try to pull the substrate down from the in-bound slot. This could damage the mylar parts of the Center Guide. Instead, work carefully to remove jammed substrate from the top of the printer.

Try to move the printhead carriage out of the way.

Lift the substrate-adjustment lever as far up as it will go.

Carefully remove any of the jammed substrate that you can lift up and out from the top of the printer. Cut the substrate if necessary.

Carefully pull the remainder of the roll down and out of the printer.

  caution:

To avoid damaging the substrate path, do not use force to pull substrate out in reverse. If it is stuck/caught in the pinchwheel or platen area, work carefully to remove it by pulling it out from the TOP of the printer, in the natural direction of substrate advance.

Lower the substrate-adjustment lever, check that there is no substrate left in the printer (especially not in the curing module), then close and lock the window.

Turn on the printer.

Reload the roll.

If some substrate continues to cause an obstruction within the printer, it can often be cleared by loading a rigid substrate type into the printer.

If you find that you have print-quality problems after a jam, try realigning the printheads.
