CONTENT

Phenomenon
A CB3 error can occur (elevation mortor of the finisher is abnormal) when the tray starts a cascade
movement while a small number of sheets, such as 2 to 4, are continuously being stapled and
stacked in one place.

Reason
When a small number of stapled exiting sheets are being stacked and the stapled side becomes
higher, they have a tendency to slip and fall down on to the opposite side during the stacking,
meaning that on the tray being shifted upwards, they catch in the swing guide ribs causing this error
to be produced.

Paper catches on this rib.

Countermeasure
An idle roller has been added to the blind cover fixed into the swing guide, so that in the conditions
described above when the tray is shifted upwards, the paper trailing edge corner is sent forward to
the tray side by the roller and the paper no longer catches in the swing guide ribs.
