  • If you press the FEED key, the buzzer sounds once for a short time, the label is fed, and media sensor sensitivity adjustment and paper length measurement are performed automatically regardless of the setting of MSW4-1.
    The buzzer sounds once for a long time after length measurement and then the printer restarts automatically.
    The length measurement result is saved to the printer and retained in memory even if the power of the printer is turned off. The length measurement result is printed in a test print.
    If the media sensor sensitivity adjustment or paper length measurement fails, the buzzer sounds and a black mark / label gaps detection error occurs.
    To resolve the error, you need to turn off the power of the printer, load the media that is currently set, and start the media sensor adjustment mode again.
Precautions for Creating Applications and Practical Operations
If printing is done immediately after the paper is partially cut and torn off, the top of the next print out may be distorted.
For printing after cutting, we recommend to print with the first line empty.
If you are using a serial interface that has a slow data transmission speed, streaks may appear in the printouts when you are printing graphics or gradated text, which require large amounts of data.
USB interfaces may be susceptible to the effects of electromagnetic interference from the host or environment.
If this is the case, try using a cable with ferrite cores on both ends, which are very effective at eliminating EMI.

  • 1.Turn off the power.
  • 2.While pressing the cover release buttons on both sides, open the top cover.
  • 3.If immediately after printing, leave the printer for several minutes until the thermal head cools down.
  • 4.Use a cotton swab dipped in ethyl alcohol to wipe the heating surfaces and paper feed rollers of the thermal heads clean of paper dust, etc.
  • 1.Thermal head
  • 2.Paper feed roller (platen)
CAUTION
  • The thermal head is hot immediately after printing. Be careful not to touch it with your hands.
  • Do not touch the heating surfaces of the thermal head with bare hands or allow metals to come into contact with it.
Refer to PRECAUTIONS IN HANDLING THE PRINTER
Clearing a Cutter Error

  • The print head is very hot immediately after printing. Be careful not to touch it with your hands.
  • Do not touch the print head with bare hands or metal objects.
Refer to PRECAUTIONS IN HANDLING THE PRINTER
Self Test
You can use self test to check for printer problems.
Performing a self test operation
  • 1.While paper is loaded, press and hold the FEED button and turn on the power.
  • 2.Hold the FEED button down for about one second until the buzzer sounds. Release the button to start self test. The printer will print its model name, version, memory switch settings, and built-in fonts.
  • 1.Printer type name
  • 2.Firmware version
  • 3.Interface settings
  • 4.Buffer size
  • 5.Memory switch settings
Hexadecimal Dump Printing
Print received data in hexadecimal. If problems such as missing or duplicated data occur, this function allows you to check whether or not the printer is receiving data correctly.
How to do hexadecimal dump printing
  • 1.Load paper.
  • 2.With the top cover open, turn on the printer power while pressing and holding the FEED key, and then close the top cover.
  • 3.The printer will print “HEX dump print mode” followed by the received data printed in hexadecimal numbers and some characters.
How to stop hexadecimal dump printing
Do one of the following to stop printing.
  • Press the FEED button consecutively three times
  • Turn off the power
  • Receive a reset command from an interface

Error Indications
  • Paper end, paper near-end
    The end of paper is detected in two stages, paper near-end and paper end.
    For paper near-end, the status LED lights amber. Prepare to replace the paper.
    For paper end, the status LED lights red and the buzzer sounds. Load a new paper roll. The buzzer may not sound depending on the memory switch setting.
  • Cover open
    If the cover is opened, the status LED lights red.
    The buzzer may sound depending on the memory switch setting.
    Do not open the cover during printing. If the cover is accidentally opened, the status LED flashes in red and the buzzer sounds. Check the paper, pull it straight out of the printer by a couple of centimeters, and then close the cover. Printing restarts. A command must be sent to restart printing depending on the memory switch setting.
  • Cutter error
    If the auto cutter stops due to paper jamming, etc., the status LED flashes in red and the buzzer sounds. Remove the cause and press the FEED key. If the auto cutter still does not move and the paper cover cannot be opened, refer to “Clearing a Cutter Error.”
    • Refer to Clearing a Cutter Error
  • Print Head Hot
    Dense printing, heavy black printing, and continuous printing in a high temperature environment increase the temperature of the print head. When the print head exceeds a certain temperature, the printer stops printing and waits until the temperature of the print head decreases. At this time, the status LED flashes in red. When the temperature decreases, printing restarts automatically.
The status display for various messages is shown below.

Notes:
*1: Buzzer sounds when MSW5-1 (buzzer setting) is set to ON.
*2: The buzzer can be set to sound or not sound with MSW10-5 (buzzer event).
*3: Indicated when a cover is opened during standby.
*4: Indicated when a cover is opened during standby.
Paper Jams
Take care to avoid obstruction of the paper outlet and paper jamming around the outlet during printing.
If paper cannot get out of the printer, it can roll up on the platen inside the printer and cause an error.
If the paper wraps around the platen, open the paper cover and carefully pull the paper out.
Precautions for Performing Printing for Which Printing Speed Changes
When printing for which the printing speed changes is performed, white lines may be printed or paper may not be fed depending on the printing conditions. To prevent these problems, change the following memory switch settings.
  • 1.Enable MSW2-3 (buffering).
  • 2.Increase the baud rate of MSW7-1 (serial baud rate).
  • 3.Change MSW10-2 (print speed) to a lower level.
CAUTION
  • Depending on the serial interface transmission speed, ambient temperature, print data duty, and other factors, changing the above settings may not eliminate the problems.
