SP 2930 Adjustments
SP2930 controls the operation of the 2nd cleaning blade. There are two modes of
operation: ‘normal humidity’, and ‘low humidity’. The threshold between these two
humidity modes is set with SP 2930 008.
SP2930 008
Humidity
Mode
Normal Low
This SP sets the critical level of the absolute humidity
that determines which SP codes above are used to
control the operation of 2nd blade cleaning.
[0~3/1/ 1]
0: No switching (calculated absolute humidity is
ignored)
1: 0.0022
2: 0.0040
3: 0.0060
Condition SP2902 001 SP2930 005
This SP setting determines when 2nd blade cleaning
is done.
[0~2/1/1]
0: Off. 2nd blade cleaning is never done. However,
the 2nd blade cleaning can be done manually
with SP2930 004.
1: After process control execution but only when
SP3901 is set to ON to enable process control
and:
• The temperature of the machine is less than
100°C when it is powered on.
• SP2966 is ON. This SP sets process control to
execute if the machine remains on and idle for
longer than 24 hours.
2: After the prescribed number of pages has printed.
The number of pages is prescribed by SP2930 002
or 007. If the count exceeds the number of pages
during a job, process control does not execute until
the job has finished.
Interval SP2930 002 SP2930 006
This SP sets the number of pages to count before
2nd blade cleaning. 2nd blade cleaning is done when
the count exceeds this value, but only if SP2930 001
or 006 is set to "2".
[1~100/10/1K]
Time SP2930 003 SP2930 007
This SP sets the length of time the 2nd cleaning
blade is held against the drum. At the end of this
time, the 2nd cleaning blade is retracted and does
not touch the drum until the next cleaning.
[10~90/20/1 s]
• SP 2930 004 provides a command that allows you to manually clean the drum
with the 2nd cleaning blade.
