3.4.5 Adjusting Roll paper width
The TM-U220 accommodates 76 mm {3"},69.5 mm {2.74"}, 57.5 mm {2.26"} wide paper rolls.
Note:
When you use a near-end detector equipped model, be sure not to pinch the lead wires of the near-end
detector between the roll paper guide and the roll paper holder, and to push the lead wires inside so that the
lead wire of the paper-end detector does not contact the motor gear.
When replacing the wires, be sure that the wires do not catch between the roll paper guide and the roll
paper holder.
1. Make sure the power supply is disconnected.
2. Open the roll paper cover.
3. Take off the roll paper guide from the printer by loosening the two screws.
4. Push the roll paper guide on the appropriate width (See figure above.)
