Subject: Connection Change of Switching Power Supply Fan Harness when
KR-7038 (X3e) is Installed
Model: FC22
Category Field Application UNIT
Other countermeasures To be applied when necessary Optional Kit
FactoryApplication: BF080082
CONTENT
When the internal controller (KR-7034:X3e) is installed in the FC22, the load of the switching power
supply becomes heavier. In that case when the front cover and the paper-exit cover are opened, the
power supply fan must be operated.
[Changed Contents]
Presently when fan operation is stropped by opening by the covers, there is a problem with the
temperature of the switching power supply board rising when the covers are opened. So, to operate
the fan when the covers are opened, the power supply fan controller has been changed from the door
type 24V to the main type 24V.
* Cover open: when the front cover and the paper-exit cover are opened
* The connector place of the switching power supply fan is changed.
: The connector on the switching power supply -> The connector for the LGC board
[Important]
Applied for machines up to May
z
When the front cover or the paper-exit cover is opened, the fan operation stops. Change based on
the attached file "G00F053.pdf".
"Changed method of harness" has been applied from June at the factory (BF080082).
