Tear bar model Auto cutter model

Ribbon cartridge

Power cordRoll paper guide
Fig. 2-1 Unpacking

If anything is missing, contact the dealer where you bought the printer and ask them to supply the missing part. Note that it is a good idea to keep the original box and all the packing materials just in case you need to pack the printer up again and send it somewhere at a later date.

2-2. Locating the Printer

When you locate your printer, keep the following tips in mind:

1. Protect your printer from excessive heat such as direct sunlight or heaters, and keep it away from moisture and dust.
2. Place the printer on a firm, level surface which is fairly vibration-free.
3. A steady power supply that is not subject to power surges should be connected to the printer.

For example, do not connect it to the same circuit as a large, noise-producing appliance such as a refrigerator or an air conditioner.

1. Make sure the line voltage is the voltage specified on the printer's identification plate.
2. To disconnect the printer, the plug has to be disconnected from the wall socket, which has to be located close to the printer, and easy to access.

2-3. Handling Care

1. Be careful not to drop paper clips, pins or other foreign matter into the unit as these cause the printer to malfunction.
2. Do not attempt to print when either paper or ribbon cartridge is not located in the printer, otherwise the print head can be damaged.
3. Do not open the cover while printing.
4. Do not touch the print head immediately after printing as it gets very hot.
5. Use only roll paper that is not glued to the core.
6. When the paper end mark appears on the paper, replace the roll paper before it runs out.

2-4. Maintenance

Essentially, your printer is a robust piece of equipment, but should be treated with a modicum of care in order to avoid malfunctions. For example:

1. Keep your printer in a "comfortable" environment. Roughly speaking, if you feel comfortable, then the environment is suitable for your printer.
2. Do not subject the printer to physical shocks or excessive vibration.
3. Avoid over-dusty environments. Dust is the enemy of all precision mechanical devices.
4. To clean the exterior of the printer, use a cloth barely dampened with either water with a little detergent or a little alcohol, but do not allow any liquid to fall inside the printer.
5. The interior of the printer may be cleaned with a small cleaner or a compressed-air aerosol (sold for this purpose). When performing this operation, be sure not to bend or damage any cable connections or electronic components.

8 0000

Warning!

Changing the memory switch settings can cause the printer to fail to operate correctly.

Appendix F: Peripheral Unit Driver Circuit

This printer is equipped with a circuit for driving peripheral units, such as cash drawers. A 6-pin modular connector for connection of the peripheral unit is located on the back of the printer. To connect to the drive circuit, connect the peripheral unit to the modular connector using a cable supplied by you like that one shown in the figure below.

Important!

Never connect any other type of plug to the peripheral unit connector.

Modular plug

Drive circuit

The recommended drive unit is shown below.

Notes

• Peripheral Units 1 and 2 cannot be driven simultaneously.
• For continuous driving, do not use drive duty greater than 20% .
• The status of the compulsion switch can be known from the following.

Star mode: The status of the compulsion switch can be known by using the automatic status function or commands. In the case of ENQ status, bit 7 will be "1" when pin No. 6 of the peripheral unit drive circuit is high (switch on).

ESC/POS mode: The status of the compulsion switch can be known by using the automatic status function, <DLE> <EOT> n, and <ESC> "u"n commands.

Parallel interface : The status of the compulsion switch can be known by pin No. 34 on the parallel interface connector. When the compulsion switch is on, pin No. 34 will be low. This can be checked by using the compatibility mode.

Minimum resistance for coils L1 and L2 is 24
- Absolute maximum ratings for diodes D1 and D2 (Ta = 25°C) are: Average Rectified Current Io = 1A
- Absolute maximum rating for transistors TR1 and TR2 (Ta = 25°C) are: Collector current Ic = 2A Collector loss Pc = 1.2W

Appendix G: Adjusting the Dot Alignment Mode

You may never have to use the procedure described in this section, but after you have been using your printer for some time you may find that the dots of some graphics do not align correctly. For example, what should look like:

may come out looking like one of the following:

or like this

This is caused when mechanical parts of the printer get out of alignment. This happens only rarely and you may never experience it at all throughout the life of the printer. If you do have problems, use the following procedure to correct it.

• Enter the Dot Alignment Adjust Mode according to the procedure described in Section 6-4.
• After entering the Dot Alignment Adjust Mode, a printout of the adjustment patterns similar to the printout below will be printed. The asterisk indicates the current adjustment pattern.

• To adjust, use the FEED switch to select the adjustment pattern from the printout with the smallest gap between the first printing pass and the return printing pass. Press the FEED switch once to specify the first adjustment pattern, twice to specify the second adjustment pattern, and so on up to seven times to specify the seventh adjustment pattern.

Press and hold the FEED switch the last time you press the switch.

(For example, if you want to select the fourth adjustment pattern, press the FEED switch three times. Then, press and hold the FEED switch until the long buzzer sounds.)

There are only seven adjustment patterns. The buzzer will sound each time the FEED switch is pressed. However, if you press the FEED switch more than seven times, a warning alert will sound.

After selecting the adjustment pattern, the setting value is stored in the non-volatile memory. A printout similar to the one below with the selected adjustment pattern highlighted and the message "Adjust Completed!" will be printed.

Note: Before the printout is printed, the setting value is stored in the non-volatile memory of the printer after the adjustment pattern has been selected and the long buzzer sounds. During this period, do not set the power switch to off. If this power switch is set to off when the setting value is being stored in the non-volatile memory, the setting value for the adjustment pattern and all of the memory switch settings will be reset.

Fig. 6-3 Dot Alignment Adjustment Sample 2

• The long buzzer sounds once more and the setting value is automatically set.
  The adjusting the dot alignment mode is complete.

Appendix H: Black Mark Sensor Alignment Mode

1. Turn the printer off and unplug the power cord.

2. Remove the screws. Then, remove the DIP switch cover on the bottom of the printer.

1. Since it is adjusted by rotating the volume VR22, check the position of the volume. Prepare a small slotted screwdriver that will fit in the hole.
2. Set the roll paper not for black mark.
3. Enter the black mark sensor adjustment mode according to the procedure described Section 6-4.
4. Rotate the volume VR22 using micro screwdriver, to adjust it to a position where at both the ERROR (red LED) and the POWER (green LED) lamps light.
5. Turn the power OFF.

This completes the black mark sensor adjustment.
