APPENDIX 1 – Optional Printer Operation
Operator Information
There are two buttons on the front panel of the
printer. One button operates the front door latch,
the other controls the paper feed.
Door Latch:
With the printer mounted in data mode attitude
(paper emerging downwards) so that the two
control buttons are at upper left, to open the front
door of the printer, press the door latch (the
outermost of the two buttons) sideways towards
the other button, using thumb or forefinger (see
Figure 1). This will release the latch and the door
can be swung outwards to expose the paper roll.
Paper Feed Button.
With the printer in data mode attitude press the
top part of the innermost button to activate paper
feed (see Figure 2). This will continue for as long
as the button is held down.
Paper Roll Replacement:
Open the printer door as described above and
swing the door open to expose the paper roll.
If any paper remains in the printer, tear the end
off against the paper tear bar and carefully pull
the remaining paper backwards, from the rear of
the mechanism mounting chassis, until the free
end emerges. Press the paper roll retaining
button inwards using the thumb and forefinger
(see figure 3) and remove the empty roll. Take a
new roll of paper, and separate the end from the
rest of the roll. Remove any damaged or
gummed part of the paper, and cut the free end
squarely with a pair of scissors or a knife, leaving
a clean straight edge to present to the printer
mechanism.
Thread the new roll past the retention button onto
the spindle with the paper unspooling in an
anticlockwise direction when viewed from the
open end. (See Figure 4). Press the paper feed
actuator arm (at upper left in data mode) until the
mechanism grips the paper and pulls it through to
the front of the printer. (See Figure 5).
Turn the paper roll so that any loose turns are
wound snugly against the roll. Close the printer
door.
More paper may now be fed through by pressing
the paper feed button on the front panel. (See
Figure 2).
Ribbon Cartridge Replacement:
Tear off any paper emerging from the printer.
