A5/HLT size when the APS sensor
does not detect the size.

If "A5 length/5.5" x 8.5" is selected,
paper sizes that cannot be detected
by the APS sensors are regarded as
A5 lengthwise or 5.5" x 8.5".
If "Not detected" is selected, "Cannot
detect original size" will be displayed.

Numbers 2 and 3 are used for Chinese
paper sizes (267 x 390 mm and 195 x 267
mm). The meanings of numbers 2 and 3
are the same as for number 1 and 2.
However, if the APS sensors detect the
original, the machine assumes Chinese
paper sizes.

For example:
A4 ® 195 x 267 mm
A3 ® 267 x 390 mm

Displays whether or not the standard
white level adjustment has been
done.

SYMPTOM

When a large number of sheets, such as thirty, are stapled in the multiple copy mode, a
couple of the bottom sheets in the stapled stack may be rolled up on the shift tray.

CAUSE

If the paper facedown-curls excessively, the stapled set of paper will not slide back all the
way to the extreme right position on the shift tray. If this happens, the lower leading edge
of the next set may catch on the trailing edge of the set already on the tray, causing a
couple of the bottom sheets to roll up.

This symptom could occur with a thick stapled set when the copies have piled up high on
the tray. Heavy paper sets will generate stronger friction with the paper set underneath,
and as the copies pile up, the angle of the top copies will level off and make sliding back
more difficult.

Note

: 1. Non-staple mode copies will not exhibit this symptom because single sheets of

paper are delivered to the shift tray at a time.

2. Due to the nature of the copy job type in which this problem occurs, this symptom
would more likely occur with heavy volume users such as copy shops, rather
than with casual users.

SOLUTION

1 The copy paper has a characteristic that one side creates more curl than the other

side. Therefore, instruct the customer to flip over the paper in the paper tray to reduce
the amount of paper curl.
For those customers who have a wide selection of paper brands, recommending a
paper brand which creates less curl might be more beneficial for the customer. (See
page 23 of the Copy Reference manual for related remarks.)

2 This symptom may occur more with A4/11” x 8.5” sideways feed. This is because the

paper can slide up the tray further than other paper sizes. (Larger sizes of paper will
not go that far because of the friction with the lower set of copies.)

If that is the case, install the new version ROM (#A6815103E). The new version ROM
decreases the exit speed of A4/11” x 8.5” sideways paper to drop the paper close to
the right frame for easy switch back. (This happens for stapling more than 11 sheets.)

SYMPTOM

When a large number of sheets, such as fifty, are stapled in the multiple copy mod e, a
couple of the bottom sheets in the stapled stack may be rolled up on the shift tray.

CAUSE

The leading edge of the stapled set of paper tends to hang down when fed out onto the
shift tray. If there is an excessive facedown curl at the leading edge, it may catch on the
backside of the prior stack and become rolled up.

This is more evident with thick stapled sets because the curl of the upper paper will press
against the lower paper and this exaggerates the curl.

Note

: 1. Non-staple mode copies will not exhibit this symptom as single she ets of paper

are delivered to the shift tray one at a time.

2. Due to the nature of the copy job in which this problem occurs, this symptom
would more likely occur with heavy volume users, such as copy shops, rather
than with casual users.

SOLUTION

1 The copy paper has a characteristic that one side creates more curl than the other

side. Therefore, instruct the customer to flip over the paper in the paper tray to reduce
the amount of paper curl.
For those customers who have a wide selection of paper brands, recommending a
paper brand which creates less curl might be more beneficial for the customer. (See
page 23 of the Copy Reference manual for related remarks.)

2 Install the new version ROM (#A6975156B). The new version ROM is different from

the current ROM in the following ways:

2.1 After the shift tray has moved from its stand-by position to the upper position, it
will start moving down 50 ms after the paper stack has actuated the finisher exit
sensor. Thus, the paper stack makes a “soft landing” on the shift tray, reducing
the chances of the paper being rolled up.

2.2 The finisher exit roller speed has been increased from 600 to 700 mm/s which
matches that of the stack exit. This will prevent th e leading edge from receiving
the pressure which may encourage the face-down curl.

Note

: The statement in the Service Manual (page # A697-12) that “The speed of the

exit roller is higher than the stack feed-out belt speed.” is wrong.

 T

Model:

NAD 30S/30/40 (3000-sheet Finisher)

2.3 The mode in which the shift tray receives the stapled copies at its stand-by
position after the 1,500th copy has been suspended for stapled sets of more than
35 sheets because receiving at the stand-by position may lead to a steeper paper
landing angle, causing the rolling-up.
