Media is not set
straight to the printer
Setup Media again
User's Manual
The most effective measure against Media shifting is to set
Media straight to the printer. Especially on lengthy printing,
small tilt of Media setup results in big Media shifting while
printing.
Loading roll media improperly to the printer or Take-up unit
may result in Media shifting. Follow the procedures
described in the User's manual and load roll media
correctly.
When you use the sheet media, be careful with the usage
of the front table and the rear table.
