G ETTING S TARTED
P 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.
Suitable types are:
>Arjo Wiggins Conqueror Colour Solutions 90g/m²;
>Colour Copy by Neusiedler.
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 printer. 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).

C ASSETTE TRAY
If you have identical paper stock loaded in the multi purpose tray,
you can have the printer 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 printer 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.
Paper or transparencies should be loaded print side up and top
edge into the printer.
SIZE DIMENSIONS WEIGHT (G/M²)

Light 64-74g/m²
Medium 75-90g/m²
Heavy 91-120g/m²

F ACE DOWN STACKER
The face down stacker on the top of the printer 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 printer 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.

Loading Paper> 17
L OADING P APER
C ASSETTE TRAY
1. Remove the paper tray from the printer.
2. Fan the paper to be loaded at the edges (1) and in the
middle (2) to ensure that all sheets are properly
separated, then tap the edges of the stack on a flat
surface to make it flush again (3).
123

Loading Paper> 18
3. Load the paper (for letter headed paper load face down
with top edge towards the front of the printer).
4. Adjust the rear stopper (1) and paper guides (2) to the
size of paper being used.
To prevent paper jams:
>Do not leave space between the paper and the guides
and rear stopper.
>Do not overfill the paper tray. Capacity depends on the
type of paper stock.
>Do not load damaged paper.
>Do not load paper of different sizes or types at the
same time.
>Do not pull the paper tray out during printing.
>Close the paper tray gently.
5. For face down printing, make sure the face up (rear)
stacker (3) is closed (the paper exits from the top of the
printer). Stacking capacity is approximately 250 sheets,
depending on paper weight.
6. For face up printing, make sure the face up (rear)
stacker (3) is open and the paper support (4) is extended.
Paper is stacked in reverse order and tray capacity is
approximately 100 sheets, depending on paper weight.

>When printing on headed paper load the paper into the
multi purpose tray with pre-printed side up and top
edge into the printer.
>Envelopes should be loaded face up with top edge to
the left and short edge into the printer.
>Do not exceed the paper capacity of about 50 sheets or
10 envelopes. Maximum stacking depth is 10mm.
3. Press the tray latch button (3) inwards to release the
paper platform, so that the paper is lifted and gripped in
place.
