When the rear paper stacker is folded down, paper exits through
the rear of the MFP and is stacked here face up. This is mainly
used for heavy print media. When used in conjunction with the
multi purpose feed tray, the paper path through the MFP is
essentially straight. This avoids bending the paper around curves
in the paper path and enables feeding of up to 203g/m² media.

APER RECOMMENDATIONS
Your MFP will handle a variety of print media, including a range
of paper weights and sizes, transparencies and envelopes. This
section provides general advice on choice of media, and explains
how to use each type.
The best performance will be obtained when using standard
75~90g/m² paper designed for use in copiers and laser printers.
A suitable type is Colour Copy by Mondi.
Use of heavily embossed or very rough textured paper is not
recommended.
Pre-printed stationery can be used, but the ink must not offset
when exposed to the high fuser temperatures used in the printing
process.
Envelopes should be free from twist, curl or other deformations.
They should also be of the rectangular flap type, with glue that
remains intact when subjected to hot roll pressure fusing used in
this type of MFP. Window envelopes are not suitable.
Transparencies should be of the type designed for use in copiers
and laser printers. We strongly recommend Oki transparencies
(Order No. 01074101). In particular, avoid office transparencies
designed for use by hand with marker pens. These will melt in the
fuser and cause damage.
Labels should also be of the type recommended for use in copiers
and laser printers, in which the base carrier page is entirely
covered by labels. Other types of label stock may damage the
printer due to the labels peeling off during the printing process.
A suitable type is Avery White Laser Label types 7162, 7664,
7666 (A4), or 5161 (Letter).
Business cards recommended are produced by Oki (Order
No. 09002985).

ASSETTE TRAY
The cassette tray can handle paper weights of 64g/m² to
120g/m². The cassette tray is ideal for printing A4 documents of
more than 1 page in length.

If you have identical paper stock loaded in the multi purpose tray,
you can have the MFP automatically switch to the other tray when
the current tray runs out of paper. When printing from Windows
applications, this function is enabled in the driver settings. When
printing from other systems, this function is enabled in the Print
Menu.
M
ULTI PURPOSE TRAY
The multi purpose tray can handle the same media sizes as the
cassette trays but in weights of 75g/m² to 203g/m². For very
heavy paper stock, use the face up (rear) paper stacker. This
ensures that the paper path through the MFP is almost straight.
The multi purpose tray can feed paper widths as small as 105mm
and lengths up to 1200mm (banner printing).
For paper lengths exceeding 356mm (Legal 14in.) use paper
stock between 90g/m² and 128g/m² and the face up (rear) paper
stacker.
Use the multi purpose tray for printing on envelopes and
transparencies. Up to 50 sheets of transparencies or 10

envelopes can be loaded at one time, subject to a maximum
stacking depth of 10mm.
Watermarked or headed paper should be loaded print side up and
top edge into the MFP.
F
ACE DOWN STACKER
The face down stacker on the top of the MFP can hold up to 250
sheets of 80g/m² standard paper and can handle paper stocks up
to 120g/m². Pages printed in reading order (page 1 first) will be
sorted in reading order (last page on top, facing down).
F
ACE UP STACKER
The face up stacker at the rear of the MFP should be opened and
the tray extension pulled out when required for use. In this
condition paper will exit via this path, regardless of driver
settings.
The face up stacker can hold up to 100 sheets of 80g/m²
standard paper, and can handle stocks up to 203g/m².
Always use this stacker and the multi purpose feeder for paper
stocks heavier than 120g/m².
