Poor gear efficiency can cause the arm to generate higher normal
forces. If the pick assembly is noisy, replacement may be required.
The arm must pivot freely through its full range of motion. On 500
sheet trays there are wrap springs located on the pivot arbors of the
arm. These springs aid to prevent the arm from bouncing. If the arm
appears to be binding or sticky near the bottom of the tray these
springs may be the problem. Reducing the tension on the
counterbalance spring may be used as a temporary fix to get
additional weight at bottom, until the pick assembly can be replaced.
However, the counterbalance spring is not to be considered an
adjustment for feeding problems.

Autoconnect Cabling and Connectors
The printer options make electrical connection automatically or
autoconnects requiring no external cables when the option is
mechanically installed under the printer. Communication between
the option and the base printer stops when you remove an option
located above or below the printer. The printer no longer recognizes
the option and deletes associated messages. Each installed option
below the base printer provides an electrical autoconnect to the
option attached below it. The output expander option attached above
the base printer provides power to the option above it. We do not
recommend to attach or "Hot Plug" any options with the base printer
power turned On.
