Is the platen positioned at a level
that is too low?
Adjust the height of the platen corresponding to
the print medium before using it.
You can use the platen height adjustment lever
from the menu to adjust the height of platen.
As a rough indication, adjust the height so that it
is lowered by one step from the limit height
detected by the obstacle sensor, and check that
the platen is not detected by the sensor.
