To ensure proper printing quality, the default values for the following
SP modes have been reviewed and some SP modes newly added.
-SP3-920-001 (Lubrication Cleaning Time) ( ): old default
[0 ~ 100 / 50 (100) / 1% /step]
-SP2-941-001(OPC Lubricant Time – job end )
[0 ~ 30 / 14 (20) / 1s /step]
-SP3-921-001 (Lubricant Clutch OFF: 1C): Newly added
-SP3-921-002 (Lubricant Clutch OFF: 2C/3C/4C): Newly added
[0 ~ 11 / 6 / 1s /step]
Allows the image transfer belt cleaning clutch off timing to be adjusted.
The setting determines the number of seconds after image transfer
belt cleaning roller charging that the clutch is turned off. With previous
versions, the clutch is always running while the development roller
motor rotates.
-SP2-938-001 (OPC Reverse Interval): Newly added
[0 ~ 100 / 10 / 10 counts /step]
The Main motor rotates the OPC belt backwards for 500 ms at the end
of every job, in order to remove foreign particles between the OPC belt
and OPC cleaning blade. However, this does not need to be performed
so often.
In addition, reducing the frequency of OPC belt reverse
rotation improves the cleaning blade performance.
This SP adjusts the counter for the OPC belt reverse rotation, and is
incremented as follows:
LT/A4 LEF or smaller: 1, larger than LT/A4 LEF: 2.
When this SP reaches its set maximum, reverse rotation is performed
for 500ms at job end.
NOTE : Along with this main unit controller version, be sure to update the
BICU firmware to v1.42 or later. For fetails, please refer to RTB #RG071007
(black faint images).
Changes made in preparation for the addition of SP3-921-01/02 (from the next
version).
Note: These SP modes are not yet operational.
New SP mode added: SP2-803-01 (Charge Cleaning Off time).
[0 ~ 200 / 60 / 10 seconds/step]
Although a 60-second interval already exists for performing an idle discharge after
corona wire cleaning, this new SP mode allows the interval to be adjusted. The idle
discharge is to maintain an even charge wire surface, ensuring proper charging.
The new Wireless LAN card (produced from Dec '02) is sometimes unable to
communicate with the PC after a certain interval when using 802.11adhoc mode.
Note: This does not occur with 1) adhoc or infrastructurer modes, or 2) previous
Wireless LAN cards (produced up until Nov '02).
SP1-105-01 (Fusing Temperature): Default for idling start changed from 145 to 140
(see SP mode table below).
