Setting the Paper Roll Width
The TM-U220 accommodates 76 mm {3"}, 69.5 mm {2.74"}, and 57.5 mm {2.26"} width paper rolls
with no adjustments. For the each roll width, use the roll paper spacer included with the printer.
Note:
❏
The default paper width setting value saved in NV memory is 76 mm. So, if the customer does not use
76 mm width paper, return the printer only after setting the memory switch to the customer’s paper
width value using the appropriate method for each printer function below.
Use the TM Service Utility (See page 2-5.)
Use the Memory Switch Setup Mode (See page 5-12.)
❏
For printer models with a paper near-end detector, be careful not to pinch the near-end detector lead
wires between the roll paper spacer and the roll paper holder, and be sure to push the lead wires inside,
so that the paper-end detector lead wires do not contact the motor gear.
1. Open the paper roll cover.
2. To set the each roll paper width, position the spacer as shown in the illustration below.
3. Position the roll paper spacer for the appropriate paper width. (See figure above.)
4. Tighten the spacer with 2 screws included with the spacer. (See figure above.)
