6 Troubleshoot substrate issues
The substrate cannot be loaded successfully
Here are a few things to check if you cannot successfully load the substrate.
●
The substrate might be loaded at an angle (skewed or mislocated). Make sure that the right edge of the
substrate is aligned with the roll on the input spindle.
●
The substrate might be crumpled or warped, or have irregular edges.
●
If the substrate jams in the substrate path to the platen, the leading edge of the substrate might not be
straight or clean. Remove the initial 2 cm (1 in) of substrate from the roll and try again. This might be
necessary even with a new roll of substrate.
●
Make sure that the spindle is correctly inserted.
●
Make sure that the substrate is correctly loaded on the spindle, and that it loads over the roll towards
you.
●
Make sure that the substrate is wound tightly.
The substrate has jammed
When a jam occurs, the Possible substrate jam message usually appears in the front panel, with one of
several error codes (see
Front-panel error messages on page 45).
If you are trying to load a very thin or very thick substrate, remember to follow the special procedure
described in the User's guide for loading such substrates.
Check the substrate 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. Then feed the substrate through the
printer, and load a new roll.
●
Otherwise, follow the procedure described under
Check the printhead path on page 31

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