PAPER RECOMMENDATIONS
Your printer 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 weight 
20 – 24 lb (75 – 90 g/m²) paper designed for use in copiers and 
laser printers. Suitable types are:
>OKI® Bright White, 32 lb US Bond
>HammerMill® Laser Print Radiant, White, 24 lb US Bond
>Xerox® 4024, 20lb US Bond
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. 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. Suitable types are:
>Avery White Laser Label types 7162, 7664, 7666 (A4), or 
5161 (Letter)

TRAYS AND STACKERS
TRAYS 1 TO 5
Tray 1 is the standard blank paper input tray and can hold up to 530 
sheets of 20 lb (75 g/m²) paper. Additional trays, to give a total of 
five, can be added as an option to give a total tray capacity of 2650 
sheets of 20 lb (75 g/m²) paper.
If you have identical paper stock loaded in another tray (for example 
Tray 2 or the MP Tray), you can have the printer automatically 
switch to that other tray when the current tray runs out of paper. 
This function can be enabled by driver settings when printing from a 
Windows application or by a menu setting when printing from other 
applications.
MP TRAY
The multi-purpose tray is used for media sizes additional to those of 
the standard trays, heavier media weights and special media.
The multi-purpose tray can handle the same sizes as the standard 
trays but in weights up to 71.3  lb (268  g/m²). For very heavy paper 
stock use the face-up 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 3in 
(76.2 mm) and lengths up to 47.24 in (1200 mm). For banner 
printing, recommended sizes are Letter wide, 35.43 in and 47.24 in 
long and weight 34 lb (128 g/m²).
Use the multi purpose tray for printing on envelopes and 
transparencies. Up to 100 sheets of transparencies or 25 envelopes 
can be loaded at one time, subject to a maximum stacking depth of 
1 in.
Paper or transparencies should be loaded print side up and top edge 
into the printer. Do not use the duplex (two-sided printing) function 
for transparencies.

FACE-DOWN STACKER
The face-down stacker on the top of the printer can hold up to 500 
sheets of 20 lb (80 g/m²) standard paper, and can handle paper 
stocks from 17 – 57 lb (64 – 216 g/m²). Pages printed in reading 
order (page  1 first) will be sorted in reading order (last page on top, 
facing down).
FACE-UP STACKER
The face-up stacker should be opened and the tray extension pulled 
out when required for use. (With the face-up stacker either open or 
closed, the driver setting of Face Down will successfully direct prints 
to the Face-Down stacker.)
The face-up stacker can hold up to 250 sheets of 20 lb (80 g/m²) 
standard paper and can handle stocks up to 71.3 lb (268 g/m²).
Always use this stacker and the multi-purpose feeder for paper 
stocks heavier than 57 lb (216 g/m²).
DUPLEX UNIT T 
The duplex unit (C9850hdn models) provides automatic two-sided 
printing on plain paper fed from Trays 1 – 5 or the MP Tray. 
Applicable paper sizes are A6, A5, B5, B5LEF, Executive, A4, A4LEF, 
Letter, LetterLEF, Legal 13 in, Legal 13.5 in, Legal 14 in, B4, 
Tabloid, Tabloid Extra, A3, A3 Wide, A3 Nobi, Custom size (3.9 –
 12.9  in wide, 5.8  –18  in long), using paper stocks in the range 20  –
 32 lb (75 – 120 g/m²).
