Roll paper end detection
When paper has exhausted and paper slackness is eliminated, the
roll sensor lever is fully pushed. Then, light to the roll paper end
sensor is blocked and the roll paper end detection signal is sent to
the roll holder PCB. When the roll holder PCB detects the roll paper
end detection signal, it stops rotation of the roll drive shaft. At the
same time, the roll paper end detection signal is sent to the formatter
PCB through the roll holder PCB and "NO PAPER" is indicated on
the operation panel.
