Firmware History for B051/B052
Corrects the following:
•
Toner accumulates on the edge of the ITB cleaning blade. Turning the ITB clutch Off/On,
forces accumulated toner on the blade edge to drop on the ITB while the image is not
transferred on the ITB for cleaning. If it is not performed, toner may drop on the printing
image. These SP's adjust the time and number of times for blade cleaning.
-2-924-001(ITB Cleaning Clutch Off/On – Time)
[100 ~ 500/ 300 / 10ms /step]
-2-924-002 (ITB Cleaning Clutch Off/On – Number)
[0 ~ 5/ 2 / 1 /step]
•
The lubrication cleaning time has been revised. SP mode has been subdivided into time
for 1C and time for 2C/3C/4C.
-SP3-920-001 (Lubrication Cleaning Time: - 1C)
[0 ~ 100 / 50 / 1% /step]
-SP3-920-002 (Lubrication Cleaning Time: - 2C/3C/4C)
[0 ~ 100 / 100/ 1% /step]
•
Eliminated unnecessary occurrences of SC420 (Fusing bias discharge error). SC420 will
not be shown when a leak occurs because of a small hole on the fusing belt surface.
Field experience has confirmed that belt lifetime is actually longer when the SC is not
shown in these conditions. If a leak should occur, the machine turns SP2-501 OFF
(fusing bias SW), and the fusing bias is not applied until the fusing counter is cleared and
the SP is set back to ON or PM counter (SP7-803-7) is cleared.
-SP2-501-001 (Fusing Bias SW)
[0 ~ 1 / 1/ 1: ON 0: OFF]
•
When printing the magenta mono color, Cyan color may mix slightly on the magenta
image.
•

To correct this, the image processing has been reviewed.
NOTE: Along with this BICU version, be sure to update the main unit controller firmware to
version 2.02.9 or later.
