Paper Holding Section
The paper roll holding mechanism is a shaft support type. The paper roll holding section
consists of the removable
shaft, roll paper
, the
holder, roll paper A
(for the inner diameter of
the paper core: 25.4 mm {1 inch}) that fits the size of the paper roll core used, the
holder, roll
paper shaft
that supports the
shaft, roll paper
and the
plate, roll paper guide
that holds the
sides of the paper roll.
The paper holding section turns on a fixed screw section so that the paper holding section can be
opened and closed. The paper holding section can be opened by pulling down the
plate,
opening and shutting
while holding down the
lever, open
. When closing the paper holding
section, pull up the
plate, opening and shutting
causing the
lever, open
to be locked
automatically; then the paper holding section is closed securely.
Note:
If the paper inner core dimension differs from the
holder, roll paper A
due to the paper thickness, you
can replace it with an optional holder, a
holder, roll paper B
(for the inner diameter of the paper core:
50.8 mm {2 inch}) or a
holder, paper roll C
(for the inner diameter of the paper core: 76.2 mm {3
inch}).
Paper Load-absorbing Mechanism
The paper load-absorbing mechanism consists of the
guide, roll paper tension
that receives
the paper tension. Using the paper tensile force generated when feeding the paper, this
mechanism oscillates the
guide, roll paper tension
and reduces the paper feeding load due to
inertia of the paper roll.
Paper NE Detector
The
paper NE detector
has two kind of detections, the primary NE detection and the
secondary NE detection. The primary NE detection can detect the amount remaining on the
paper roll using a reflecting photo sensor. After the primary NE detection, the secondary
detection can be used to return the status when the paper is fed to the length specified by the
memory switch setting. (See SW No. 2, 3 in Table 2-10 on
page 2-20.)
The
paper NE detector
is mounted on the
frame
and is secured with a screw. The position of
the
paper NE detector
can be altered to adjust the setting for the amount remaining on the
paper roll.
