Adjusting the Paper Near-End Sensor
When you install the printer horizontally, you can use the paper near-end sensor.
Below are two situations where a paper near-end sensor adjustment is required.
•To adjust the detection position to suit the diameter of the roll paper core used.
•To adjust the detection positi
on of the remaining amount of roll paper.
Follow the steps below to adjust the roll paper near-end sensor.
1
Open the roll paper cover.
2
Loosen the adjustment screw fastening the sensor, and align the upper
edge of the positioning plate with the adjustment position.
3
Tighten the adjustment screw.
To use the paper near-end sensor, it needs to be enabled with the memory switch. To set
the memory switch, see
"Setting the Memory Switches/Receipt Enhancement" on page
51.
When you install the printer vertically or hang it on a wall, be sure to disable the paper
near-end sensor. Otherwise false detection occur.
Since roll paper cores vary slightly in shape, depending on paper roll design and
manufacturing tolerances, it is impossible to detect the remaining paper exactly.
Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm
{0.71"} so that the paper near-end sensor can detect the remaining paper as accurately
as possible.
Whether to let printing stop when the roll paper is nearly out can be selected by a
command. For information about ESC/POS commands, see the ESC/POS Command
Reference.
Whether to let the Paper LED light when the roll paper is nearly out can be selected with
the memory switch. To set the memory switch, see
"Setting the Memory Switches/
Receipt Enhancement" on page 51
.
Enabling/disabling of Feed button can be selected by a command. If the command is set
to disable this button, it does not function. For information about ESC/POS commands,
see the ESC/POS Command Reference.
Adjustment position Remaining amount of paper (outer diameter)
Upper Approx. 27 mm {1.06"}
Lower (Initial setting) Approx. 23 mm {0.91"}
