SPECIAL ADJUSTMENTS
Paper Near End Sensor
The near end
sensor for paper roll
in the printer is able to
have the printer work
with paper rolls of
several bobbin sizes.
Please refer to the
picture at right for the
inside of the paper roll
compartment that there are a plastic thumb wheel for bobbin size adjustment
and a sensor block in the wall. Turn the thumb wheel to adjust the proper
position of sensor block. For desktop application, the sensor block should be
above the bobbin seating on the 2 support rollers on bottom of paper
compartment when paper near end.. The acceptable paper roll bobbin outer
diameter is between 18 and 24 mm.
58mm Paper Spacing Plate
The application of 58 mm width paper roll in this printer can be
achieved through adoption of an option spacing plate and an internal DIP
switch setting. Please refer to the last chapter of this manual for the DIP switch
setting. Please refer to the middle picture above for the 58 mm paper spacing
plate with its flange at top edge showing out. Insert the noted corners of the
spacing plate into the 3 dents inside the paper roll compartment as arrowed in
the left picture above with point A goes in first. Then the 58 mm paper roll sub
compartment is formed as in the right picture above.
Paper Cutting
The paper advance after a normal cut with auto paper feed is set to 12
mm. In case the user applies cut without paper feed through DIP switch setting
change to have something like a logo printed on top of each slip, it is also
highly suggested to print the logo and necessary paper feeding to make 12 mm
paper advance right after each cut to prevent curling up and jamming of paper
