Media transport
Media transport path
Media is supplied from tray 3 or tray 4, and is transported to the printer along the media transport path.
Media transport path
The following is a cross section of the printer and the 1TM, showing the main components directly associated
with the media path and transport.
Functions of main components
When the 1TM is installed under the printer, additional trays are available.
Media tray assembly
It is necessary to adjust the rear and the end guide in the media tray assembly to match the media size.
Rear media guide
The rear media guide can be adjusted to different media sizes by moving it to the front or rear. The guide comes
into contact with the rear edge of the media and holds it in position.
Bottom plate
The force pushing up the bottom plate is transmitted by the driving force of the motor on the media feed unit
assembly. The bottom plate is pushed up by the rotation of the lift up shaft, which causes the supplied media to
come in contact with the pick roller.
