The following is a small series to introduce you to the common problems and troubleshooting of thermal printers.
1. Is the serial printer connection garbled?
A: The wave rate set by the PC host is consistent with the printer and will not print garbled characters;
2. The printer has paper, but the red light flashes?
A: The print head is overheated or the printer does not detect the black mark, and the print head or cutter is not connected correctly;
3. The printer does not open the cash box or the cash box automatically opens after being turned on. Can't it be turned off?
A: Please check whether the printer is connected to the cash box interface. If it is consistent and the cash box is connected correctly, please send it to the designated service point for repair; the latter is the bad case of the cash box drive circuit, please send it to the designated service point for maintenance.
4. Does the printer not check the paper?
A: The movement sensor is too dirty. Please clean the sensor with a soft brush. If it is still unable to check the paper after cleaning, please send it to the designated service point for repair.
5. The printer took a while to print garbled characters online?
A: The printer interface board is damaged. Please replace the communication interface board or send it to the designated service point for repair.
6. The indicator light on the control panel is not lit?
A: Check if the power cord is properly inserted into the printer, power adapter and power outlet. Check if the printer's power switch is turned on. If these are normal, please send it to the designated service point for repair.
7. The printer is not printed clearly?
A: It is mainly to see whether the entire printing format is unclear or partially unclear. If the entire printing format is unclear, the quality of the printing paper may not meet the standard; if it is not clear, the print head may be too dirty. Clean the thermal head of the print head with cotton cloth and alcohol. After cleaning, it is still unclear. Please send it to the designated service point for repair.
8. How do I install a driver for a network shared printer?
A: Enter the network neighborhood, find the shared printer on the computer with the shared printer, double-click the print, install the driver to print locally.
9. Often half of the paper is cut off when cutting paper?
A: The blade is deformed or the blade is not elastic enough to reinforce the elastic piece or replace the blade in the blade on the flip.
10.80 series Ethernet interface printing multiple machines at the same time, sometimes communication interruption can not print, how to troubleshoot?
A: Please check whether the printer connection network is stable first, then press each printer to self-test and check if the printer Ethernet Id has duplicate conflicts. If there is a duplicate conflict, please change the Ethernetl ID number using the Ethernet interface printer tool on the printer CD-ROM. Make each printer's Ethernet ID number unique.
11. The printer cutter is stuck, how to troubleshoot?
A: At this time, it is strictly forbidden to use a hard object to open directly. First, press the flip or pat twice, and restart the machine to check whether the cutter can be reset. If the cutter still cannot be reset, you can manually adjust the micro-knife in the cutter. . First open the front cover of the printer, move the internal gear of the cutter by hand, and slowly rotate to return the cutter. Or use a Phillips screwdriver to adjust the knob inside the cutter, and slowly rotate to return the cutter, then open the flip.
12. The printer accidentally entered the water, what should I do?
Answer: The power should be turned off immediately. Dry the main board and the movement with a hair dryer. Note that the temperature should not be too high. The normal operating temperature is about 50 °C.
13. How to start the high speed drive mode?
A: Turn the SW-8 bit of the printer DIP switch to ON. The printing speed is based on the original high-speed printing. The high-speed driving mode is adopted, and the driving speed of the driving graphics is increased by 100mm/s from the old version of 27mm/s, which is reduced. Noise during printing. Ethernet printer status monitoring support, Ethernet multi-connection support, OPOS and a variety of international language printing support, serial port multiple check digit optional functions (serial optional check digits with or without parity, odd parity, even parity , spaces, tags).
14. How to set the kitchen to single automatic reminder function?
A: Turn the SW-6 bit of the printer DIP switch to ON to enable the printer kitchen to automatically remind you. After starting this function, if the speaker is connected to the printer cash drawer interface, when cutting the paper, the speaker can sound continuously for 5 seconds to indicate that the single print is completed. (Note: When the printer cash drawer interface is connected to the cash box, do not turn the SW-6 bit ON, otherwise the coil of the cash box will be burned out.)
15. How to set the serial port 115200bps high-speed communication printing mode?
A: For the serial printer, you can turn ON the SW-6 bit of the DIP switch to enable the high-speed communication printing mode of the serial port 115200bps.

16. How to print a single sheet that has not been printed?
A: When the printer is incomplete due to the end of the paper, or the order is not completed, reload the paper and the printer will reprint the complete one.
17. Support software and printer binding function?
A: To protect the tangible benefits of software vendors. Once this feature is activated, the user will not be able to work with other software or other printers.
18. Can an Ethernet interface implement two connection tasks at the same time?
A: When the Ethernet interface printer is printing a connected print job, there may be another connection task waiting for printing.
