Prints do not stack properly in the bin
●
Prints at the bottom of the bin may be damaged by the weight of the prints above them. For this
reason, you are recommended to collect prints from the bin before it becomes full.
●
Coated paper with high ink content may be crumpled when falling into the bin. In this case, you are
recommended to collect prints from the bin more frequently than usual.
The printer uses a lot of paper to align the printheads
In order to align the printheads accurately, the printer sometimes needs to feed through up to 3 m (≈10
ft) of paper before starting the printhead alignment process. This is normal behavior and you should not
try to interrupt or prevent it. See
Align the printheads on page 101.
The paper moves while the printer is in standby mode
