Retrofit Information
Because of software changes, the ROM has been changed from P/N A0775105A to
P/N A0775105B.
The details of the software changes are as follows:
1. Coin lock enable
(Phenomenon)
Coin lock cannot be used.
(Cause)
With the old ROM (P/N A0775105A), if you remove the key counter from the copier before
the end of the copy cycle, the machine immediately stops and a paper misfeed might
occur. This is to prevent the key counter from being removed before the key counter
counts up.
For the above reason, a coin lock cannot be used with the old ROM.
(Solution)
At the field's request, the ROM has been changed to permit use the coin lock.
According to this change, the machine can be set so that no paper misfeed occurs even if
the key counter is removed from the copier during the copy cycle. However, if the key
counter is removed before the paper reaches the registration sensor, the key counter does
not count up.
When installing the new ROM to machines on which customers request using the coin
lock, change SP 22 data from "0" to "1 as follows:
(SP 22 is a new SP mode.)
