2) Cutting type: Partial cut (cutting with one point in l eft edge l eft uncut)
NOTES: 1. To prevent dot displac ement, after cut ting, feed paper approx imately 1 mm {14/360"} or
more before printing.
2. Paper must be fed over 40 mm {1.57"} before cutting if the printer is stopped. This
prevents a possible paper jam.

2) Roll paper end sensor: Detects whether paper is present or not.
When the sensor detects a paper-end, the pr inter stops printing.
Printing resumes when paper is installed and the printer cover is
closed.
a) Detecti on method: Microswitch
NOTE: If paper other than the speci fied one is used, the paper roll end sensor may
not work correctly.
3) Roll paper near-end sensor: Detec ts a near-end of a paper roll.
If t he sensor is enabl ed by ESC c 4, the printer stops printing.
a) Detecti on method: Microswitch
b) Near-end adjustment: Can be adjusted by changing the position of the adjusting screw.

6) Notes on preprinting on the recording surf ac e of thermal paper
When using thermal paper, the recording surface of which has been preprinted, sticking (a
problem of the thermal head sticking to t he surface of the t hermal paper duri ng printing) may
occur, causing faulty printi ng and other problems. It is, therefore, strongly recommended to
avoi d using preprinted therm al paper. I f such paper must be used, conduct prepr inting tests
under the conditions recomm ended by the paper m anufacturer (t ype of i nk/ pri nt condi t ions) and
confi r m that no faulty printing or any other problems occur before you use it for act ual printing.

2. Notes on using the power supply uni t other than the E pson specified one ( P S - 180)
• The current consumption of this printer is as shown in Figure 1.9.1. User must
consider these values when the user provides the power supply unit other than the
Epson specifi ed one.
Note that the current consumption may increase if the printer is used in a low

The USB bulk transmission method is a host-controlled transmission method. Unlike RS232
transmission, it cannot spontaneousl y interrupt data transmission to the host computer.
The printer has a 128-byte status data buff er. Statuses that exceed the buf fer capacity are
cancelled. In order to ensure that there is no lack of status data, it is necessary to
periodically ret rieve status data at the host c omputer.
