2.3 LOADING LABELS AND TAGS (CONT'D)
Adjusting for the paper width
This printer is adjusted so that quality printing can be obtained without any adjustments.
However, in certain situations, better results can be obtained if you adjust the "head pressure
balance" to compensate for different widths of label paper used.
The head pressure balance knob adjusts the amount of pressure being applied along different
sections along the length of the print head. For suggested settings of the pressure knob (1 to 4),
see the table below:
SETTING PAPER WIDTH
1 55~115 mm
2 65~115 mm
3 15~55 mm
4 15~65 mm
Note:
Adjustments are only necessary if print quality is not
satisfactory. Otherwise, you do not need to vary the head
pressure balance.

2.3.3 Adjusting the Pitch Sensor

Adjustment of the pitch sensors is usually not necessary, but the procedure is described here.
1. Lift up the front cover. Make sure that the cover is
pushed upwards until it locks firmly in place so that
it will not fall downwards and injure your hands.
2. The green sensor assembly is located just under the Ribbon Supply Spindle. Turn the purple
Sensor Adjustment knob to adjust the sensors' position. (The gap and I-mark sensors are
underneath the green plastic tabs)
3. After adjustment, feed a few labels and do a test print to see if the sensor is working properly.
Adjust the label pitch if necessary.
Caution
• When closing the front cover, be careful not to injure your fingers due to a sudden release of the heavy cover.
