    The printer may not correctly feed paper or print if it is switched to 80-mm wide paper after using 58-mm wide paper.
Refer to PRECAUTIONS IN HANDLING THE PRINTER
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.

Error Indications
  • Paper End
    If the paper ends, the ERROR LED lights and a 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 ERROR LED lights.
    The buzzer may also sound depending on the memory switch setting.
    Do not open the cover during printing. If the cover is accidentally opened, the ERROR LED flashes. 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 ERROR LED flashes. 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. The ERROR LED flashes during this time. When the temperature decreases, printing restarts automatically.
The status display for various messages is shown below.

*2 Indicated when a cover is opened during printing.
*3 The buzzer sounds when MSW5-1 (buzzer setting) is enabled.
However, the condition that the buzzer sounds varies depending on the MSW5-1 and MSW10-5 settings.
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.
Notes
  • Depending on the serial interface transmission speed, ambient temperature, print data duty, and other factors, changing the above settings may not eliminate the problems.
