3. Measurements are taken within the left and right printing areas of the platen.
Measure at 3 to 5 locations while rotating the PF roller. Be careful to prevent anything from altering
the accuracy of the measurements taken and to avoid any warped areas of the gum roller.
4. The standard gap should measure between 0.25 and 0.3mm (a range from 0.2 to 35mm can be
expected depending upon any variances).

3. Adjusting the Dot Alignment
This adjustment is made when the alignment of the print generated from left to right (outwards) does not
correspond with the print generated from right to left (inwards).
The acceptable range of displacement is a pitch of 1.
3-1 Adjustment A
1. Generate a print sample to assess the range of displacement.
2. Loosen the screw of the TM sensor board
3. If the print generated from right to left is off to the right, move the TM sensor board in the direction
indicated by the arrow 1. If the print is off to the left, move the TM sensor board in the direction
indicated by the arrow 2.
4. Tighten the screw of the TM sensor board.
5. Generate another print sample. If the print is still out of alignment, go back to step 2 and repeat the
above process.
6. If the print alignment does not improve, go to section 3-2 and go through the steps for Adjustment B.
