Service-mode tests
Stapler test/stacker test
Note Any stapler settings or offset settings that are configured at the printer or MFP control panel are
ignored during the stapler test/stacker test.
For the stapler test/stacker test, use letter-size or A4-sized paper. Feed the paper straight,
centered, and slowly to avoid skews and jams. If a jam occurs, release the interlock switch and
depress it again to reset the device.
Note Make sure that the paper is centered. If the paper is not centered, it might jam when it comes in
contact with the wings.
