Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to an anti-paper jam thermal transfer label printer. Background Art

[0002] There are multiple paper pickup rollers in the printer. After being used for a period of time, the paper pickup rollers often rub against the paper, generating static electricity, which can easily cause the paper pickup rollers to attract dust. The friction of the dusty paper pickup rollers is significantly reduced. Once the paper pickup rollers at the paper outlet lose their good paper pickup effect, it can easily cause paper jams. If you need to repair it, you need to remove the back cover of the printer, take out the paper, and then clean the paper pickup rollers. This process needs to be done manually, which is inconvenient.

[0003] For label printers used for thermal transfer anti-paper jam, reference patent number: CN113978142B, an anti-paper jam printer, a lifting mechanism drives the cutting mechanism and the cleaning mechanism to descend, the cutting mechanism cuts the paper while the cleaning mechanism cleans the paper pickup roller.

[0004] However, when the above printers are in use, the dust inside cannot be cleaned out in time. Although the dust on the pickup roller is cleaned and dropped, the dust remains and accumulates inside the printer. Subsequent use will accelerate the adhesion of dust to the pickup roller, affecting the stability of subsequent printer use.

[0005] For this reason, we propose a paper jam-proof thermal transfer label printer. Utility Model Content
