3-bin mailbox
The optional 3-bin mailbox has one bin that stacks up to 500 sheets and two bins that stack
up to 100 sheets each, for a total capacity of 700 sheets.
The 3-bin mailbox has three operating modes: mailbox mode, stacker mode, and function
separator mode. Each mode is explained in the sections that follow.
Mailbox mode
The bins can be assigned to a user or to a group of users. All print, copy, and fax jobs that
an assigned user or group of users sends are delivered to the designated bin. Each user can
select the bin in the printer driver or at the control panel.
When the designated bin is full, the MFP stops printing. Printing continues only when you
empty the bin.
Stacker mode
The 3-bin mailbox can combine the bins to act as a stacker. It can stack up to 700 sheets of
75 g/m
2 (20 lb bond) paper. Jobs are sent to the bottom bin first, then to the middle bin, and
then to the top bin. Print jobs that require more than 500 sheets fill the bottom bin and
continue stacking into the middle and top bins.
When all three bins are full, the MFP stops printing. Printing continues only when you
remove paper from the top bin. The MFP does not resume printing if you remove paper from
the bottom bin or the middle bin before you remove paper from the top bin.
Note Do not remove paper from the top bin and then attempt to put it in place again. This causes
the pages to stack in the incorrect order.
When the 3-bin mailbox is in stacker mode, you cannot designate that a job be sent to a
particular bin.
Function-separator mode
You can configure the bins to receive jobs that come from a specific MFP function, such as
printed jobs, copy jobs, or faxes. For instance, you can specify that all copy jobs are sent to
the top bin.
The MFP stops functioning when the designated bin is full. Printing, copying, or faxing can
continue only when you empty the bin.
Using the 3-bin mailbox
You can select the operating mode at the control panel and in the printer driver.
Note When you select the operating mode in the printer driver, the settings must match the
operation mode that is set at the control panel.
When using mailbox mode, use the either printer driver or the control panel to assign bins to
a user or group of users. When using function-separator mode, use the control panel to
assign the bins to each function.
