1.3 Sensor mechanism

1.3.1 Paper sensor

The paper sensor is located immediately before
the thermal head to detect whether recording
paper is present or not. Applying electrical
power to the thermal head while recording paper
is not inserted could result in damage to the head
or reduce the service life of it. The paper sensor
is provided to help prevent this, as well as to
detect whether recording paper is inserted or not
in the case of auto loading.

1.2 Mechanism for attaching and detaching the platen roller

The platen roller, which is a part of the mechanism for feeding recording paper, is removable
with this printer. The platen roller, which has the platen gear, platen bushings and platen holder
attached, comprises a platen roller unit. When this unit is placed in the U-formed bearings of the
chassis, the platen gear engages the motor gear. The wire springs, with one end anchored to the
chassis, press against the platen bushings to keep the roller in contact with the thermal head. The
platen roller unit can be attached or removed by hooking or unhooking the movable ends of the
wire springs to or from the hooks on the chassis.
