1. Model name:
ER-A310
2. General:
The following two have been changed for improving the quality of the printer CR-510.
1) Quality keeping of the paper feeding unit locking
The paper feeding unit sometimes remains unclosed and the fixing lever R does 
not normally hook the protrusion of the unit not to lock when shutting the paper
feeding unit of the printer after opening it against a paper jam, when pulling the
release lever R toward you or the operation is so slow and the paper feeding unit 
is not pressed down.
The printer’s printing sometimes results faint difficult to read.
This trouble does not occur when the speed of shutting the paper feeding unit or of
the operation of the release lever R is normal.
The paper feeding unit is shut by pressing it with fingers to ensure the locking.
The paper feeding unit has been improved to shut smoother since January, 1997.
Refer to Fig.1 for its mechanism.
