position of sensor head. The acceptable paper roll bobbin outer diameter is 
between 18 and 22mm. This adjustment allows sensor activation on paper roll 
overall diameter between 21 and 23.6 mm unless for too light bobbins. 
Remember, for smaller roll diameter, the sensor head should go higher. 
Paper Roll Replacement 
When the paper roll 
to put (back) in is already 
nearly used up, the paper roll 
must be placed in the way that 
the paper roll touches the 
sensor head from the outer 
surface but never allow the 
sensor head to ride on the 
bobbin body between the inner and outer diameter of the paper roll bobbin nor 
to go into the inner diameter of the paper roll bobbin. It is also noticed that 
some market available paper roll has extremely light bobbin, easily causing the 
paper roll to go off position when paper feeding with low remaining paper. In 
this case, the paper near end sensor may function abnormally and it would be a 
good solution to set in the setup window to have the printer to send busy only 
when input buffer is full and not based on every off line signal. 
Spacer Plate 
If the paper roll is of width less than the standard 80 / 58 mm, it may 
run away from the paper near end sensor during application resulting in an 
error status. In this case, please stick the spacer plate to the wall opposite to the 
paper near end sensor in the paper roll compartment. Each spacer plate 
compensates 1 mm paper roll width shortage. There will be 1 spacer plate in 
the accessory of the printer. If the  user uses narrower paper roll and requires 
more spacer plates, it can be purchased from Posiflex. 
Paper Cutting 
The paper advance after a protective cut is set to 12 mm. In case the 
user uses direct cut instead of protective cut 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 front edge inside the paper exit slot. 
Wall Mount Application 
In wall mount application, the paper near end sensor will not  work 
properly and it is suggested to set in the setup window to have the printer to 
send busy only when input buffer is full and not based on every off line signal.
