When the main power is off, the maintenance flushing is not performed
and it may cause the Head nozzle clogging. Make sure to power on/off
with only the sub power switch for daily use.
The most effective measure against Media shifting is to set Media
straight to the machine. Especially on lengthy printing, small tilt of
Media setup results in big Media shifting while printing.
Loading roll media improperly to the machine or Take-up unit may
result in Media shifting. Follow the procedures described in the User's
manual and load roll media correctly.
When dust such as pieces of vinyl is stuck to the Grit Roller, ability to
hold Media decreases and it results in Media shifting. Use a brush to
clean the Grit Roller.
When pinch rollers wear out, ability to hold media decreases and it
results in media shifting. Referential time for replacing Pinch Roller is
24 months.
