11. Precautions when fixing the platen roller block
- The external case that fixes the platen roller block should have sufficient strength in
design to prevent deformation or wobbling by impact, twist or external force, and the
rotation axis that fixes the external case should be designed to prevent fluctuation in a left
and right direction. Otherwise it may cause paper jamming or printing quality degradation
due to incomplete closing of external case. Conduct sufficient verification by using the
device in actual operating environment.
- Provide sufficient strength to the door rotation system as a certain level of force will be
applied to the external case while installing or removing the platen roller block. Use shaft-
type material to design the rotation axis of the door rotation system so that platen roller
block is installed safely.
- When thermal paper is newly installed, it should be installed by depressing the center of
the external case in the door rotation system. Installing the paper by depressing only one
side of the external case may cause problems in the installation of the platen roller block,
causing paper detection failure or printing failure. Provide information to users so that
they always install the paper by depressing the center of the external case.
