8.5.3 Precautions for image missing width on the paper trailing edge
at enlargement copying
[ 1 ] Phenomenon
The bottom margin may disappear and the image is sometimes missing if an A4-size original is copied
to an A3-size sheet by enlarging the size.
The range of the bottom margin at actual-size copying is 2.0 mm +/- 1.0 mm (measured value).
However, if this tolerance is located in the minus direction (bottom margin: 1 mm or 0 mm), this
phenomenon will easily occur.
[ 2 ] Countermeasure
When this phenomenon has occurred during enlargement copying, adjust the image dimension using
the following procedure.
Procedure:
(1) Perform image dimensional adjustment (bottom margin adjustment) by aligning the value to the
center one (2.0 mm).
* The value must be aligned to the center one. No tolerance value +/- 1.0 mm is included.
Refer to P. 6-22 "[H] Bottom margin"
(2) Adjust the secondary scanning data laser writing start position by aligning the value to the center
one (52 mm) in 05-4058 (drawer) and 05-4061 (bypass tray).
* The value must be aligned to the center one. No tolerance value +/- 0.5 mm is included.
Refer to P. 6-12 "[D] Secondary scanning data laser writing start position"
8.5.4 Precautions for incorrect Operation of Automatic Original Size
Detection <20H/23H/25H, 23HA/28HA>
[ 1 ] Phenomenon
When the APS mode is selected and an original is scanned after it has been placed on the original
glass, the automatic paper size detection sometimes works incorrectly.
• When copying: "SET CORRECT DRAWER. PRESS [START]" is displayed even though the size of
the set paper and that of the original is the same.
• When scanning/fax: A scan/fax job is sent with a size larger than the one for the original.
[ 2 ] Cause
The original size is detected incorrectly caused by lights from a ceiling lighting which directly applying to
the CIS sensor.
The original size detection function detects the width of an original by lighting the optical source while
the platen cover is being closed.
During scanning of the original size while the platen cover is being closed, lights from a lighting device
sometimes directly apply to the CIS sensor through an area which is not covered by the original. As a
result, the size may be detected as one larger than the actual one.
• A4 series: No misdetection occurs with A3 and A4 originals. A size larger than the actual one may
be detected with A4-R, A5-R, B4, B5, B5-R, 8K, 16K and 16K-R originals.
• LT series: No misdetection occurs with LT and LD originals. A size larger than the actual one may be
detected with ST, ST-R, LT-R and LG originals.
