MECHANISM FOR THE PRINTER CR-510
[Parts changes]
1. Model name:
ER-A310
2. General:
The following have been changed for improving the quality of the printer CR-510.
1) Improvement of the paper feed unit, locking mechanism.
The paper feeding unit sometimes remains open and the fixing lever R does
not lock when shutting the paper feeding unit of the printer after opening it
to clear a paper jam.
The printing sometimes appears faint or difficult to read.
This problem does not occur when the speed of shutting the paper feeding unit or
the operation of the release lever R is normal.
The paper feeding unit is shut by pressing it firmly to ensure it locks.
The paper feeding unit has been improved to shut more smoothly.
Refer to Fig.1 for its mechanism.
