6.1.3 Precautions for Securing the Printer
Pay attention to the following when designing the case and securing the printer. Failure to follow these
instructions may cause deterioration of print quality, paper skew, paper jam, noise or damage.
Prevent excessive force or torsion when securing the printer.
Remove the platen block before securing the printer.
The bracket for the platen block is made of aluminum. Secure it with an appropriate torque.
Design the case so that the thermal head control terminals can move 1 to 2 mm to compensate
for the head moving.
If the FFC for the thermal head control touches the bottom of the outer case, the FFC will
disconnect and/or short-circuit. Leave a space of approximately 0.3 mm between the bottom of
the outer case where the FFC passes through and the bottom of the printer mechanism.
Secure the platen block to the printer correctly as shown in Figure 7-1. The platen block should
not be used in any other way than as described in Figure 7-1.
