NOTES: 1. Notes on using the Epson PS-180 power supply unit

If the printing is continuously performed with the high print ratio, the overcurrent limitation might be operated. Therefore, the printing length must not exceed the following values when printi ng with high pri nt ration.

Print r atio: Number of dots being ener gized per one dotline / T otal number of dots

per one dotli ne (512 dots)

Table 1.9.2 Limitation of the Printing Length on Print Ratio

Print ratio 80% 100% Print example

Print length 30 mm or less 20 mm or less

If t he overcurrent l imitati on is operated when printing i s continuously performed wit h a high print ratio, uneven print density or a low voltage error may occur.

2. Notes on using the power supply uni t other than t he 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 specified one. Note that the current consumption may increase if the printer is used in a low temperature or the pri nt density i s set t o “ dar k ” .

• The power supply unit with a small power capacity may not operate the printer correctly.

• Contact Epson if you need more detail ed infor mati on.

1) The printer mechanism stops but does not become busy when: an er r or has occurred, the cover is open, printing stops due to a paper-end, or paper is fed using t he paper feed butt on.

2) W hen setti ng DIP switch 2-1 to O N to enable handshaking wit h the printer , be sure to check the printer status using the GS a command and t he ASB function. In this setting, the default value of n for GS a is 2. The printer aut omati c ally t r ansmits the printer status, depending on onli ne/offli ne changes.

3) When using DLE EOT, DLE ENQ, and DLE DC4 be sure that the receive buffer does not bec ome full.

• When using a host t hat cannot transmit data when the pr inter is busy: If an error has occurred, DLE EOT, DLE ENQ, and DLE DC4 cannot be used when the

printer is busy due to a receive buffer- full state.

• When using a host t hat can transmit data when the printer is busy: When the receiv e buff er becomes full whil e transmitting bit-image data, DLE EO T , DLE ENQ

or DLE DC4 used while sending the bit-image data is processed as bit-image data. The data transmitted when the receiv e buffer is f ull may be lost.

3.9 Cover Open Sensor

The cover open sensor monitors the printer cover. When the sensor detects a cover open during printing, the error LED flashes and the printer stops printing. The printer recovers when the cover is closed. When the sensor detects a cover open while the printer is in the standby status, the printer goes offline. The printer recovers when the cover is closed.

NOTE: Whether the cover is open or not does not affect the status reported by the roll paper end

sensor.

3.10 Print Buffer-full Pri n ting

• When printing in standard mode When subsequent data is received after the printer processes one line of data in the print buffer, the

printer automatically prints the processed line and feeds the paper by one line (in standard mode).

• When printing in page mode When subsequent data is received after the printer processes one line of data in the print buffer, the

printer automatically moves the printing position to the line after the processed one.

6.2 Explanation of Terms

1) Real-time command

Real-ti me com mands are identified with a DLE extension such as DLE EOT , DLE ENQ, or DLE DC4. The printer executes these comm ands as soon as they are receiv ed.

2) Obsolete command

Obsolete commands are commands that will not be supported by future print er models. Therefore, we recommend replacing them with more rec ent, upward-compatible c ommands that have t he same functions.

3) NV memory write command

NV mem or y write commands delete or stor e data in the NV memor y ( flash ROM )

GS ( E <some functions>, GS ( L / GS 8 L <some functi ons> , GS g 0, FS g 1, FS q

4) ESC/PO S Handshaking Protocol

ESC/POS Handshaking Protocol is a handshaking protoc ol between the host com puter and the printer when the printer tr ansmits data. The ESC/PO S Handshaking Protocol is required if t he following commands are executed:

GS ( L / GS 8 L <some functions>

5) Print buff er

The print buff er is used to store image data for pr inting

6) Receive buf fer

The receive buffer is used to store data f r om the host computer. A ll receiv ed data is stored in this buffer and processed in the order recei ved.
