Remarks for thermal head installation

If the following remarks are not followed, the thermal head will be installed
incorrectly.
1) Fit the base's springs [A] over the protrusions [B] on the underside of the
thermal head (5 points).
2) While fitting the tops of the springs [A] over the protrusions on the underside
of the thermal head, hook the lock pawls [C] of the thermal head onto the
base (3 lock pawls). Make sure to set the front side (the paper table side)
first.
3) The spring in the middle is longer than the other ones. Therefore, set the
central protrusion first, then fit the other protrusions into the springs. Make
sure that all protrusions are properly fit into the springs. With the master
making unit removed from the machine, you can look from the tension roller
side to check if the springs are fitted properly.
