To ensure the print quality and prolong the life of the print head, the printer must keep the print head clean during use. Clean the print head, rubber roller, and ribbon sensor with alcohol every time you print a roll of labels. When replacing the print cable, turn off the power of the printer and computer before connecting the cable. Note: Turn off the power first when cleaning the print head, etc. The print head is a precision part, it is best to ask professionals to assist in cleaning!
