4.8 Paper Near End Function
If the paper is running out, the PNE sensor informs the host computer that the paper is running out, by
means of a signal output or the PAPER lamp on the panel. The PAPER lamp is illuminated unconditionally.
1. If the PNE sensor detects that the paper is running out, the PAPER lamp will be illuminated.
2. If PNE is enabled, the parallel interface will output PE. (At initial setting)
3. Printing is allowed up to about 1.5 m. (Initial value) After printing or feeding the paper by a specified
amount, the parallel interface will output BUSY and FAULT, and serial interface will output DTR to stop
printing, respectively.
4. Replace the paper according to the procedure in "4.3 Inserting the Paper."
5. After replacing the paper, cancel the BUSY (DTR), FAULT, and PE outputs.
(1) The following lists the outputs made by the near paper end function and the paper end function. The
output state can be changed by the DIP switch or a command.

(2) Print amount after detecting PNE
When PNE is enabled, a printable amount after PNE detection can be adjusted. PNE is detected when
the remaining amount of the paper roll is about 2∼3 m. (It depends on the paper quality used, paper
thickness, and operating environment.)
An initial value is 1.5 m. Up to 1.5 m can be printed after detecting PNE. At this time, with the
approx. 70µm-thick recommended paper, the remaining amount of the paper will be about 0.5∼1.5 m
when printing stops.
It can be adjusted between 0 and 2.55 m with a command. Adjust it depending on the operating
environment and paper quality.
Depending on an adjustment value, paper end may be detected (Printing stop) first.
If PNE is detected at power-on, a set amount of printing will be done from that point. (The default is
1.5 m)
