Firmware History for B051/B052
Corrects the following:
•
The "toner cartridge setting error" is sometimes displayed even when the cartridge has
been set correctly. This is due to misdetection of the information on the cartridge memory
chip.
•
8"x13" SEF is misdetected as A4 SEF in the by-pass tray.
(EU/Asia versions only).
•
Default settings for the following have been changed (new defaults underlined).
SP1-003-5, -6, -7 (Paper Buckle for By-pass Tray):
•
SP1-003-5 By-pass: Plain
[-4 ~ 6 / 3 / 1mm /step]
•
SP1-003-6 By-pass: Thick
[-4 ~ 6 / 0 / 1mm /step]
•
SP1-003-7 By-pass: OHP
[-4 ~ 6 / 0 / 1mm /step]
•
Eliminated unnecessary occurrences of SC410 (2nd transfer electric leakage):
SC410 tends to occur frequently when using paper with high moisture content under
high-temperature, high-humidity when the resistance on the paper transfer roller is low.
The roller current was previously lowered for mono-color mode (45% that of full color),
which lowered the resistance and caused frequent occurrences. This version uses the
color mode current for mono-color until job end to eliminate unnecessary occurrences
under the conditions described above.
Default for SP2-803-01 (Charge Cleaning Off time) changed to minimize idling time
during wire cleaning.
. [0 ~ 200 / 10 / 10 seconds/step]
NOTE: This adjustment was added from version 1.233:01, and the description has been
added to the version 1.233.01 description below (previously missing).
•
SP modes newly added (listed below).
These SPs have been added to ensure proper (higher) transfer belt cleaning by applying
the following bias voltages at job end (OPC lubrication time):
SP2-400-008: Cleaning Bias LL1: OPC lubrication time
SP2-401-008: Cleaning Bias LL2: OPC lubrication time
SP2-402-008: Cleaning Bias NN1: OPC lubrication time
SP2-403-008: Cleaning Bias NN2: OPC lubrication time
SP2-404-008: Cleaning Bias HH: OPC lubrication time
[0 to 2000/ 1400 / 10 Volt/step]
•
Minimum value changed for SP2-941-01, -02 (OPC lubrication time).
Minimum increased from 0 to 6:
SP2-941-01: Job End: [6 ~ 30 / 14 / 1 s/step]
SP2-941-02: OPC Lubrication Interval: [6 ~ 60 / 10 / 1 s/step]
NOTE: Along with this BICU version, be sure to update the main unit controller firmware to
version 2.02 or later.
