A250 COPIER FIRMWARE MODIFICATION HISTORY
DESCRIPTION OF MODIFICATION
•
1st Mass Production
•
The default setting for the maintenance
LED display (SP5-908) has been
changed as follows.
NEW: 1 (Yes)
OLD: 0 (No)
•
When the value of the total counter is
over 9999 or a negative value, the SC
history and jam histories are displayed
incorrectly (out of order).
•
If the machine receives a fax message
during a print or copy job (with rotate-
sort), the polygonal motor does not stop
after the job has been completed.
•
It is occasionally required to press the
interrupt key more than once to produce
a response.
•
The machine can not determine the 8k
and 16k when auto- enlarge / auto-
reduce is performed.
•
When the machine goes into low power
mode while warming up, the temperature
of the fusing unit does not drop (as it
should).
•
When clearing the NV-RAM memory, the
setting for the polygon motor idling time
(SP2-915) is 15 sec (1), although it
should be 25 sec (2).
•
The firmware will be modified so that
SC620 will be displayed when an ADF
from another machine is installed.
