Installation and Operation of Printer

Printer Unpacking

Check the parts:

• Before use, make sure the accessories are included in the package(the following picture is an example). If any thing is missing, contact the supplier or manufacturer.
• The specific accessories may not be included depending on the printer model.

Connecting the Printer

Connect the power line

1. Confirm that the power switch is in an off (0) state.
2. Connect the power adapter to the printer.
3. Connect the power line to the power adapter.
4. Connect the other end of the power line to a nearby socket.

Use the special power adapter for the printer.
The connection diagram is as follows:

Connect the USB cable

1. Connect the USB cable to the printer.
2. Connect the USB cable to the PC host.
3. Turn the power switch to on (1) state.

Folded Paper Loading

1. Facing the back of the machine, hold the paper guide with both hands, and adjust the distance between the left and right guides according to the folded paper size.
2. Insert the folded paper into the paper guide
3. Confirm that the printer has detected paper feeding, automatically feeds paper and delivers paper normally

Handling of Paper Jam

1. Move the top cover lever forward with both hands and lift the top cover.
2. Remove the jammed paper from the feeding channel, and check whether the print head has adhesive or carbon deposition. If yes, clean it with an alcohol cloth, remove the wrinkled paper and replace it with new paper.
3. 5.5 Bluetooth Pairing and Printing (only valid for printers with Bluetooth)
   Bluetooth printer needs to be paired with the main device driving
   the printer before working, and the pairing process is initiated by the main device.

The general pairing method is as follows:

1. Turn on the printer
2. The main device searches for external Bluetooth device.
3. If there are multiple external Bluetooth device, select the printer corresponding to BDA address. (see self-test page for details.)
4. Enter the initial password “0000” or “1234”.
5. Complete the pairing.

Please refer to the Bluetooth function description of the main device for the specific pairing method.When pairing, the label printer with Bluetooth interface must be on.
Note: During pairing, please do not turn on multiple printers at the same time, otherwise you may not be able to judge which printer was successfully paired.

• After successful pairing, other host computers can still be paired with the printer, and each printer can be paired with up to 8 host computers. If more upper computers are paired with printers, the host computer paired with the printer at the earliest will be automatically removed from the pairing list by the printer. At this time, if this host computer needs to drive the printer for printing, it needs to be paired again. (For multi-connected Bluetooth only.)

Use Bluetooth Interface for Printing (only valid for printers with Bluetooth)

• For host computers with virtual Bluetooth serial ports (such as mobile phones using SMARTPHONE, POCKET PC, PALM, notebook computer, etc.), after successful pairing, printing data can be sent to the printer via the virtual Bluetooth serial port for printing. If the host computer does not have a virtual Bluetooth serial port, when you want to drive the printer for printing, please consult the supplier of the host computer.

The Switch, Key and Indicator Light of Printer

Precautions for power switch/use

1. Turn the printer power switch to on (1) state, and the printer will be turned on.
2. Turn the printer power switch to off (O) state, and the printer will be turned off.
3. Turn off the printer with power switch. If you pull the power plug directly, it is easy to damage the internal circuit of the printer and cause print data loss.
4. After power-off, wait for a while (not more than 5 seconds) before turning on the printer again otherwise it is likely to cause a failure.
5. Please use the original battery of this machine, otherwise it may lead low print quality or damage to the printer.

Attention:

• Make sure the power supply is connected before turning on the printer.

Printer Test

Print Self-Test Page

When the printer is initially installed or there are any problems with the printer, you can run self-test program to confirm the following status: firmware version, printer parameter setting status, print quality, and related setting information of external devices, etc. After confirming that there is no problem with the printer after the self-test, please check other devices or software. This function runs independently of other devices or software.

The self-test method is as follows:

**** Confirm that the printer is connected to power supply and the paper roll is loaded

• Confirm that the printer is turned off and the top cover is closed in place.
• Press and hold the FEED button, then press the POWER button to turn on the printer; release the button after the printer is turned on.

Print with the Window Driver

1. To install Windows driver, please refer to “Driver Installation Instruction”.
2. Set the “port” of the Windows driver as the appropriate interface to use. Print the test page with the “Print test page” function of Windows

Label Learning

Note: In the following cases, the user can perform label positioning learning so that the printer can better position the label:

• Install and use the printer for the first
• First use of printer after sensor
• Reuse the printer after it is not used for a long
• Replace with a new type of paper
• The printer cannot recognize the mark effectively during printing.
• When the printer is ready, press and hold the FEED button for 3s until the standby status indicator flashes twice, release the button, and the printer will start learning and feed paper. If the printer learns under continuous paper mode,
• the learning is invalid.
• Users can also complete the learning through the printer tool software. (refer to “Instruction for Printer Setting Tool”.)

Note: After learning, you can re-open the top cover and place the blank label paper just fed during learning back for printing to avoid paper waste.

USB Interface
