3-bin mailbox feed and delivery system
When the 3-bin mailbox (MBM) is installed, it receives print media from the print engine and delivers
it to one of its three bins. The 3-bin mailbox has the following components:
■ One feed motor that drives the rollers
■ Two solenoids that operate the inlet deflector and the bin deflector
■ Six sensors that detect the presence of print media and the stack height in the output bins
■ One switch that determines whether the 3-bin mailbox is attached to the MFP correctly
■ One fan that cools components inside the 3-bin mailbox
The 3-bin mailbox has three operating modes: stacker mode, mailbox mode, and function-separator
mode.
The MBM-driver PCA controls all functions in the 3-bin mailbox. To deliver media to the different
bins, the inlet deflector and the bin deflector change position as required.
