Notes on Using the Auto Cutter 1) To print after a cut, feed 1 mm (8-dot line) or more of paper. 2) If the cutter is not in its home position after an error, first eliminate the cause of the error; then, turn the power back ON.
4. Attaching the Accessories The following accessories do not necessarily have to be attached. Attach them if necessary. • Holding plate • Rubber feet • Switch cover 4-1. Attaching the Holder Plate (1) Attach the holding plate to the printer. Then tighten the two screws that were supplied to secure it in place.
4-2. Attaching the Rubber Feet (1) Attach the four rubber feet in the positions shown in the figure. Ensure that any soiling has been completely wiped off before attaching the rubber feet. (2) Push the cover open lever, and open the printer cover.

5. Consumable Parts and AC Adapter When consumable parts have run out, use those specified in the table below. Make sure that the AC adapter specified in the table is used. Use of consumable parts or AC adapter which are not specified in the table may result in dam- age to the printer, fire or electric shock.
Note: 1) Depending on the type and thickness of the paper, it may be necessary to change the settings for printing darkness. To change the darkness settings, use the printing dark- ness settings command <ESC><RS> ‘d’ n or the memory switch. Please consult the dealer for details.
