Table of Contents

The tray full detection depends on the size of the paper and the number of sheets

in one stapled and folded booklet.

In the table below, the conditions (

illustration on the previous page) refer to the states of the sensors described on the

previous page.

Full 3 (or lower tray not installed)

In the tables below:

• "Sht" denotes "sheets in a stack".

• "Cnt" denotes "Count" (see below for an explanation).

After a booklet is feed out, the fold roller motor stops the exit roller. The machine

then monitors the tray full sensors every 100 ms. The machine checks for a certain

condition, based on the size of the paper and the number of sheets in the booklet.

An example is shown below. Tell the operators that the number of sheets that the

lower tray can hold will vary greatly.

Lower Tray Full Condition Table

After the copier makes a booklet with 1 sheet of A3/DLT paper, the machine

checks every 100 ms for the 'Full 1' condition. If the Full 1 condition occurs 3 times

(shaded block in the table above), the machine detects that the tray is full.

After the copier makes a booklet with 5 sheets of A4/LT paper, the machine checks

every 100 ms for the 'Full 2' condition. If the Full 2 condition occurs 20 times

(shaded block in the table above), the machine detects that the tray is full.
