DADH
Run the following components:
• Enter dC330 code 05-030 DADH CVT motor to rotate the DADH CVT roll, PL 5.25 Item 5.
• Enter dC330 code 05-020 feed motor, to run the DADH takeaway rolls, PL 5.35 Item 6.
• Enter dC330 code 05-020 and add code 05-025 feed solenoid, to energize the feed
clutch, PL 5.15 Item 9.
Possible causes and potential solutions are:
• Excessive noise from the DADH when duplex documents are being recirculated for
copying the second side.
Possible causes are:
– The DADH speeds up during second side recirculation when in duplex mode.
Solution:
– Switch off the acceleration in duplex mode. Set dC131 NVM location 05-012 DADH
Dup Motor Spd to 1.
NOTE: The default value for dC131 NVM location 05-012 DADH Dup Motor Spd is
0.
• Grinding noise.
Possible causes are:
– The intermediate feed bearing, PL 5.15 Item 22 can stick, preventing the feed roll
from free wheeling as the document is transported by takeaway roll.
– Large flat spots, confined to one or two areas on the retard roll, which causes feed
noise and an increase in 05-330, 05-331and 05-335 jams.
Solution:
– Install a new the feed assembly, PL 5.15 Item 18.
• Noise from the DADH input tray.
Possible causes are:
– Document guides.
Solution:
– Clean the DADH input tray in the area below the input guides with antistatic fluid, PL
26.10 Item 19.
• Squeaks from the DADH.
Possible causes are:
– DADH exit roll assembly or takeaway roll assembly, PL 5.35 Item 6.
Solution:
– Remove and clean the shafts and plastic bushes with antistatic fluid, PL 26.10 Item
19.
• Knocking noise.
Possible causes are:
– The feed motor and CVT motor are not tensioned correctly, causing the drive belts to
slip.
Solution:
– Adjust the DADH drive belts, ADJ 5.1.
• Gear rattle.
Possible causes are:
– A loose meshing of the clutch and motor gears PL 5.15 Item 9 and PL 5.15 Item 16.
Solution:
– Adjust the DADH drive belts, ADJ 5.1.
ROS
Run the following components:
• Enter dC330 code 06-020 ROS motor, to drive the ROS motor at normal run speed, PL
6.10 Item 4.
• Enter dC330 code 06-025 ROS motor, to drive the ROS motor at standby speed, PL 6.10
Item 4.
The ROS gives out a ascending frequency, a whining noise for a duration between 5 and 6
seconds. The whining noise is the normal sound of the ROS motor accelerating.
