Problem: The printer has garbled characters
Reason: 1. Communication issues
2. Main board memory issue
3. Static electricity issues
4. Image issues
1. Check if there are any issues with the USB cable;
2. If there is a memory issue with the motherboard, you can turn off the printer and reinsert the memory card onto the motherboard to see if it can print properly. If it cannot, replace it with a new memory card;
3. Static electricity problem: Static electricity problems may cause misalignment and ghosting. When using, be sure to plug in the grounding wire to avoid problems caused by static electricity;
4. Insufficient buffer space for computer printing software, resulting in garbled graphics: When drawing, do not overuse the computer and try not to install antivirus software to avoid conflicts with the printer driver.
