Ricoh B010 Service Manual page 296

Rev. 05/2002
DESCRIPTION OF MODIFICATION
Symptom:
When customers use low duty mode
to make high-volume copy jobs
(relative to the ACV), the toner
concentration in the development unit
increases. This causes the
oversupplied toner to drop onto the
copies, especially under low
temperature conditions.
Solution:
Change the "Weekly Output Volume"
according to the customer's average
weekly copy volume from inside
System Setting – General features:
Less than 750m (2,500 ft): Low duty
mode (default).
More than 750m (2,500 ft): High duty
mode
Action in the field:
Please instruct customers on the
following points at machine
installation:
1) Method for how to enter UP Mode
and change the Weekly Output
Volume value.
2) For the first 1-2 months following
installation, have the customer keep
track of their copy volume at weekly
intervals. The weekly changes in CV
over this time will enable them to
decide which of the 2 settings is best
for them.
Note: For customers installing the
B010 as a replacement machine,
please use the weekly ACV on the
previous machine for reference and
set the Weekly Output Volume
accordingly (as a starting point).
