Changing the Paper Width
This printer accommodates 80 mm wide roll paper with no adjustments. For rolls from 38
mm to 70 mm wide, use the roll paper spacer included with the printer. (If the rolls are
from 61 to 70 mm wide, break two tabs off the back of the roll paper spacer. (You can still
use widths from 38 mm to 60 mm with the roll paper spacer with the tabs broken off. See
illustration F) Follow the steps below to attach the roll paper spacer.
1.Open the roll paper cover.
2.Insert the roll paper spacer so that the front edge goes through the notch; then push
down the spacer so that the hook on the spacer and the shaft align. See illustration G.
3.Push the roll paper spacer until you feel it clicks onto the shaft. Check that the roll
paper spacer slides smoothly to the left and right.
4.Slide the roll paper spacer to the appropriate width. You can use the ruler printed
inside the printer, aligning the inside edge of the spacer with the desired
measurement. See illustration H.
Tighten the spacer with the screw included with the spacer as shown in illustration.
(Although there are two holes, this is the only one to put the screw in.)
