If you load the thick paper incorrectly you may damage the printer.
Be sure to insert the thick paper following the steps described below. If you insert the thick paper in a different way (for example, if you insert the thick paper into the printer and then turn the power off and then back on), the printer may be damaged.
Be sure to remove the roll paper holder when printing on thick paper. Otherwise, the paper is ejected and a paper jam error occurs.
Since the paper feeds through the printer from the front to the rear, make sure there is enough space at the rear of the printer for the thick paper to eject completely.
Do not insert the thick paper while the printer is operating. Otherwise, your printer may be damaged.
