TM-T20III cutter cover,

Epson TM-T20III cutter cover (1864623) is a replacement cover for the receipt printer’s cutter area. It provides access to the autocutter mechanism during a paper jam, when the roll paper cover cannot be opened.

The TM-T20III guide identifies the cutter cover as a distinct printer part. To clear this type of jam, the guide says to slide the cover toward the front to open it, return the cutter blade to its normal position, and close the cover. This part is intended for the Epson TM-T20III and gives access to the cutter mechanism for that recovery procedure.
