Firmware History for G060

MAIN ENGINE FIRMWARE HISTORY:

DESCRIPTION OF MODIFICATION
Installed from the first mass production.
Charge and development bias applied
during the toner end recovery mode has
been changed to optimize the drum
cleaning function.
The frequency to control the color drum
motor has been optimized so that the motor
starts smoothly rotating.
The following specification change has been
applied:
The yield target of PCUs has been changed
from 100KP to 50KP.
The following problems have been fixed.
The machine suddenly keeps running due
to memory overflow.
SC670 when the machine starts waking up
from the energy saver mode
The following problem has been fixed.
Black developer initialization fails because
toner is mistakenly supplied due to software
bug, causing SC370 (Developer
Initialization Error – Black). This happens
when performing only the black developer
initialization. (If performing the developer
initialization for black and other color(s)
simultaneously, this problem does not
occur.)
If the main switch is tuned off and on, the
SC code is reset and the machine re-starts
the developer initialization. In the worst
case, toner flows out from development unit
(the entrance area where toner is supplied)
to the inside of machine.
A fusing clutch has been added to
maximize the life of the fusing unit and oil
supply unit. This firmware version was
temporarily installed in production machines
to keep the clutch constantly moving, until
the clutch control program could be added
to the next version (1.15E).
NOTE: Therefore this version has not been
released.
