AR-M351U/M451U, AR-M355U/M455U  MACHINE OPERATION  10 - 1
[10] MACHINE OPERATION
1. Acceptable originals
A stack of up to 50 original sheets (30 original sheets*
1
 for 8-1/2" x
14" (B4) or larger) of the same size paper can be set in the docu-
ment feeder tray provided the stack height is within the limit shown
below.
A stack of up to 30 mixed size originals can be set if the width of
the originals is the same and the stack height is within the limit
shown below. In this case, however, stapling and duplex will not
function and some special functions may not give the expected
result.
*1: For paper heavier than 28 lbs. (105g/m
2
), only a stack of up to
15 sheets can be set. Setting 16 or more sheets may cause
incorrect scanning of original and scanned image may
become expanded compared with original itself.

originals out of the specified range may cause an original mis-
feed.
to remove any staples or paper clips.
• If originals have damp spots from correction fluid, ink or glue
• Do not use the following originals. These originals may cause
incorrect original size detection, original misfeeds, and smudges
on copies.
• When using originals with two or three holes, place them so that
the punched edge is at a position other than the feed slot.
2. Standard original placement 
orientations
3. Automatic copy image rotation - 
rotation copying
If the orientation of the originals and copy paper are different, the
original image will be automatically rotated 90° and copied. (When
an image is rotated, a message will be displayed.) If a function is
selected that is not suitable for rotation, such as enlarging the
copy to greater than 8-1/2" x 11" (A4) size or staple sorting with
the saddle stitch finisher, rotation will not be possible.

B. Applicable special paper
For satisfactory results, special paper must conform to the following requirements.
5. Printing onto envelopes
• Do not use envelopes that have metal clasps, plastic snaps,
string closures, windows, linings, self-adhesive patches or syn-
thetic materials. Attempting to print on these may cause mis-
feeds, inadequate toner adherence or other trouble.
• Creases or smudging may occur. This is especially true of
embossed surfaces and other irregular surfaces.
• Under high humidity and temperature conditions the glue flaps
on some envelopes may become sticky and be sealed closed
when printed.
• Use only envelopes which are flat and crisply folded. Curled or
poorly formed envelopes may be poorly printed or may cause
misfeeds.
A. Fusing unit pressure adjusting levers
When feeding envelopes from the multi purpose drawer, damage
to the envelopes or smudges on prints may occur even if enve-
lopes within specification are used. In this case, the problem may
be reduced by shifting the fusing unit pressure adjusting levers
from the normal position to the lower pressure position. Follow the
procedure below.
NOTE: Be sure to return the lever to the normal position when
finished feeding envelopes. If not, inadequate toner
adherence, paper misfeeds or other trouble may occur.
1) Unlatch the duplex module and slide it to the left.
Unlatch the module and gently move the module away from
the machine. If the machine is not equipped with a duplex
module, open the side cover similarly.
2) Lower the two fusing unit pressure adjusting levers marked A
and B in the illustration.
3) Gently close the duplex module.
If the machine is not equipped with a duplex module, close the
side cover.
