2.10.22 Adjusting the duplex blower speed
NOTE
• When you replace the duplex blower drive
board, you do not need to adjust the blower
speed. They are adjusted at the factory
(including spare parts).
• The blower speed is changed according to
amount of the copies stacked in the duplex tray.
Measure the low, medium, and high speed of the blower using a digital tachometer. They can
separately be adjusted by the three dials (VR1, VR2, and VR3) on the duplex blower drive board as
follows:
VR1 Low speed adjustment Standard: 4,500 rpm
VR2 Medium speed adjustment Standard: 6,000 rpm
VR3 High speed adjustment Standard: 7,000 rpm
CAUTION
This adjustment is usually prohibited.

The side fence width is just the same as the copy width in the duplex tray, or 0.5 mm wider. The
width can be adjusted by pressing "Side Fence" key in service tool [5-02].
