Firmware notes
*1. Upgrade the MAIN and MMI rmware at the same time, to prevent error code CF000. *2. Please note that the setting of maintenance mode U327 (setting cassette heater control) will return to the default value OFF, when upgrading the rmware to version 004.001 from an older version. (See service bulletin 2H7-006 for further details) *3. Perform AC calibration at maintenance mode U464 (set ID adjustment mode) after upgrading the engine rmware to version 006.009 or higher.
Serial numbers of affected machines
Type Serial number
TASKalfa250ci QJK9Z11560
TASKalfa300ci QJE9Z02977
TASKalfa400ci QJA9Z01847
TASKalfa500ci QHW9Z01098
Machines produced after the above mentioned serial numbers, should not have the above mentioned phenomena.
Item Contents
1 Background on the image
due to lower toner charge capacity.
2 Background on the image
when operating at half
speed mode.
Phenomenon
Background may occur on the image
Cause
After endured printing the toner charge capacity is lowered and the toner rell speed
is changed according to the developer drive time.
Solution
The modes at maintenance mode U325 (Setting the paper interval) will be internally set as follows:
TASKalfa400ci/500ci
Mode1: 0 to 3333 minutes Mode4: 3334 to 6666 minutes Mode5: 6667 minutes
TASKalfa250ci/300ci
Mode1: 0 to 4333 minutes Mode4: 4334 to 8666 minutes Mode5: 8667 minutes
Phenomenon
Background may occur on the image at half speed mode.
Cause
The T/C sensor read value is different between the full speed mode and half speed mode. The Vcont is adjusted at half speed mode, however the toner may be relled in excess in case the adjustment timing does not fulll the adjustment trigger.
Solution
The new adjustment trigger has been added, according to the Vcont variation.
