7. Switch on the printer.
8. Reload the roll, or load a new sheet. See Load a roll into the printer [4020] on page 24 or Load a
single sheet [4020] on page 28 .
9. If you find that there is still some paper causing an obstruction within the printer, it can often be
cleared by loading a rigid paper type into the printer.
10. If you find that you have print quality problems after a paper jam, try realigning the printheads.
See
Align the printheads on page 101 .
Check paper path
● This problem can occur when a roll has finished and the end of the roll is stuck to the cardboard
core. If this has happened, cut the end of the roll away from the core; you should then be able to
feed the paper through the printer, and load a new roll.
● Otherwise, follow the procedure described above, under Check printhead path on page 132 .
