Note:
In print entered please turn off the power of the printer, or it will cause the mainboard chip burned. After loading the print head, please do not install the ribbon on 10 pieces of paper so that the new needle goes through the break-in process, and then put on the ribbon. I hope you can be careful of the operation.
