5.4 Self-checking
Self-checking can test whether the printer is working well or not, if it can print
The test list correctly, that means the printer is good enough (which is excluding the
problem with the connected interface to PC); otherwise, it needs repair.

English character and some Chinese characters by order.
Self-checking procedure：Make sure the printer is connected to the
power, then press the feed key and switch on the power supply while the key is still

5.5.1 Paper near end detection function
When the paper is near to use out, the light coupling sensor can sense the status,
on the printer up face PAPER light will turn on. The working principle is as follow: in
the printer paper house, the paper roll height is higher than the height of the light
coupling, means there is enough paper, the PAPER light will be off. The paper roll
height is lower than the light coupling, means there is little paper, and the PAPER
light will be on.
