8.3 MOUNTING A ROLL HOLDER
FOR HEAD SENSITIVE PAPER
Design the roll holder to the following
specifications:
1) No sideways deviation between
holder and inlet.
2) Less than 2mm between holder
and the sides of the roll.
3) The holder does not touch the
sides of the roll.
4) The horizontal axis of the roll in the
holder is parallel with the inlet (see
Figure 8-8).
Example of improper design:
•
Roll without core
1) The roll rolls easily.
2) The roll remains securely in
the holder.
Design conditions:
The paper feed tension is
expressed as “X g or more” in the
specifications. Since this is a
specification for the printer feed,
design the roll holder so that the
paper tension is “X g or less”.
