1. Large-capacity output trays
The stacker has 3 bins, each of which can hold up to 670 sheets of A4 or Letter size paper (64
g/m2). Using the all 3 bins, total of up to about 2,000 sheets of paper can be stacked.
2. Job offset
This feature shifts the very first page of each job to one side when it is output and groups the
printed paper in the tray by the job.
3. Stapling mechanism
By the control signal from an external device, stapling positions on the leading edge of the paper
can be selected from two points in the middle, one point on the nearer corner and one point on
the farther corner.
