POSITIONING OF THE THERMAL HEAD
1. Preparation for positioning the head.
Confirm that the label cassette is in an appropriate condition.
y
Adjust the space to be “+0.2 to 1.0 mm” between the guide lever and the label width.
y
Adjust the space to be “+0.1 to 0.4 mm” between the guide and the label backing paper.
2. Remove the cover printer from the head section.
3. Load the cassette properly to the main body.
4. Select the Printer Adjustment screen, and set the head resistance.
5. Touch the [PAGE] key to set the label information, and touch the [FEED] key several times
to feed the label.
6. Touch the [Checker Mark] key and press the [PRINT] three times to see the third or
thereafter label. Check that there is no misalignment at the right or left and no irregular
printing on the label.
7. Perform the following procedures when the print adjustment is necessary.
a. How to adjust the standard position.
Loosen the fixing screws ((1) in the figure), and adjust the front end of the printer bracket
comes to the same end of the thermal head stay. Then, lightly tighten the screws. Try to
perform test printing to decide the appropriate position.
b. If printing is too light over the label
The cause can be assumed that the center line of the heating element of the thermal head and
the center line of the print roller are misaligned to the front or back in parallel. Therefore, move
the fixing screws ((1) in the figure), to the front or back and decide the positions so that the
printing gets deeper.
c. If the printing density is different at the left and the right
The cause of the lighter part can be assumed that the thermal head is misaligned to the front or
back for the center line of the print roller. Therefore, loosen the fixing screws ((1) in the figure)
and move them so that the left and right of the thermal head comes in parallel (both center lines
are overlapped viewing from the above) to the center line of the print roller, then tighten the
screws.
d. If the print position is misaligned left or right
Loosen the fixing screws ((1) in the figure), and move the thermal head position in the reverse
direction while keeping the above mentioned center lines in parallel, then tighten the screws.
