➀ Open the printer cover.
➁ Turn the ribbon-tightening knob in the direction of the arrow to take up any slack
in the ribbon.
➂ Fit the ribbon between the head unit and the ribbon mask. Then push the
cassette firmly into position.
➃ Turn the ribbon-tightening knob five or six times in the direction of the arrow to
feed the ribbon smoothly into place between the head unit and the ribbon mask.
- Check that the ribbon is not twisted or creased.
CAUTION:
. Do not turn the ribbon-tightening knob in the reverse direction.
➄ Close the printer cover.
■ Exchanging the ribbon cassette
Be sure to use a ribbon cassette that matches the specifications.
➀ Open the printer cover.
➁ When removing the ribbon cassette, grasp the tab on the left side and lift
the left side out first.
➂ Install a new ribbon cassette.
See 3-1 Installing the Ribbon Cassette ➁ to ➄.

➃ Turn on the printer.
➄ While leaving some slack in the roll paper, insert the end of the roll paper
straight into the paper inlet. The printer automatically feeds the roll paper into
the printer.
➅ Press the FEED switch to continue feeding the paper until it extends about
20 cm beyond tear-off edge.
➆ Remove the take-up spool from the take-up frame.
Remove the side of the spool and insert the end of the paper roll (journal paper
when using 2-ply paper and 3-ply paper) into the groove on the spool and wrap
the roll paper around the spool two or three times. Install the flange to flange
shaft.

3-3 Adjusting the Paper Near-End Detector
■
The paper near-end detector
The paper near-end detector senses when the paper is nearing its end and turns
on the PAPER LED.
The paper near-end detector can be adjusted according the thickness of the
paper core.
n Adjusting the paper near-end detector
Roll paper differs in paper core size, so you may need to adjust the paper nearend detector.
➀ Make sure the paper core inside diameter (Ød) is 10.5 to 12.5 mm.
➁ Measure the paper core thickness A (Refer to Figure below) for the roll paper
to be used.
➂ Determine the corresponding adjustment value from the table below.
Table 3-1. Paper Core Thickness and its Graduation Degrees

.
➃ The adjusting screw which holds the roll paper near-end detector, may be
loosened and then set the top of “B” to the adjustment value found in ➂, and
tighten the adjusting screw. (The adjusting screw can be turned with a coin.)
Screw
➄ Be sure that the detecting lever operates smoothly after finishing the adjustment.
NOTES:
l
Since the adjustment values in Table 3-1 are calculated from standard
measurements, there may be some variations depending on the model.
* If a roll paper with a red end mark at the paper end is used, this mark may
cause the paper to stick together. If this occurs, the dimension A differs from
the table.
- Be sure that the detecting lever operates smoothly after finishing the
adjustment.
* If the roll paper becomes loose due to poor paper quality, the detector may
operate incorrectly.
18
3-4 DIP Switches
n Locating DIP switches
On the bottom of your printer are DIP switches that allow the printer to be set or
perform a number of different functions.
. The switches are numbered SW-1 to SW-10 (TM-U300A/U300B) or SW-1 to SW-8
(TM-U300PA/U300PB), from left to right as shown in figure below.
. The lists on the following page describe each switch’s function.
■ Setting the DIP switches
Follow these steps when changing DIP switch settings.
➀ Turn the printer power switch off.
➁ Flip the DIP switches using tweezers or other narrow-ended tool.
Switches are on when up and off when down.
➂ The new setting takes effect when you turn on the printer.
NOTES:
* Always change DIP-switch settings when printer is turned off.
. Changes made with the power on have no effect until you turn the printer off
and then on again.
