5. Duplex Unit
6. Rear Stacker (face up)
• Capacity 100 sheets
• When the rear paper stacker is folded down, paper exits
the printer through the rear of the printer and is stacked
face up.
• This is used for labels, heavy print media, envelopes and
custom paper sizes.
• When used with the Multi-Purpose Tray, the paper path
through the printer is essentially straight. This avoids
bending the print media around curves in the paper path
and makes paper feeding more reliable.

Paper (Print Media)
General Information ________________
CAUTION!
Print media must be able to withstand 446°F (230°C)
for 0.2 second.
You need to know three characteristics about any paper (print
media) you want to use with your printer:
• Typ e
• Weight
• Size
The type, weight, and size of the paper (print media)
determine:
• which paper feed tray can be used
Choices are multipurpose tray (MP Tray/manual feed)
or Trays 1 - 2
• which paper exit path can be used
Choices are face-down or face-up (straight-through)
• whether you can use double sided (duplex) printing
For type, see
• Paper: US Bond (Metric): see page 20
• Paper: Index: see page 22
• Letterhead: see page 24
• Envelopes: see page 28
• Transparencies: see page 32
• Labels: see page 30
For weight, refer to the correct paper type. Each paper type
has a table (matrix) of paper size, paper weight, paper feed,
paper exit, simplex/duplex correlations.
For general information on paper sizes, see “Paper Size, Feed,
and Exit” on page 38.

Driver Settings ____________________
General Information
Select the thickness/type of media on which you are printing a
particular job, to produce optimum print results. This setting
overrides the setting in the printer menu.
If you are printing on a thick media such as card stock, be sure
to select one of the thicker settings (Heavy, Ultra Heavy,
Labels1, Labels 2) to get proper fusion of the toner to the page
and to prevent possible damage to the printer.
If the Ultra Heavy setting does not give proper toner fusion,
you can try the Label settings.
The default printer menu setting is Medium.
Choices are: Printer Setting, Light, Medium, Heavy, Ultra
Heavy, Labels1, Labels2, Transparency, Glossy, User Type 1,

NOTE
To determine if a paper weight is US Bond or Index,
check the metric equivalent.
35 lb US Bond = 132 g/m
35 lb Index = 64 g/m

The size, weight, and type of the paper (print media)
determine:
• which paper feed tray can be used
• which paper exit path can be used
• whether you can use double sided (duplex) printing
Single sided printing is also known as simplex printing.
These settings can be made in the printer menu or in the
printer driver.
Application settings override driver settings.
Driver settings override printer menu settings.
The best performance is obtained when using paper designed
for use in copiers and laser printers. Suitable types include:

Recommendations
• Check www.okiprintingsolutions.com for the latest
information on recommended papers for your printer.
• Paper should be stored flat, away from moisture, direct
sunlight and heat sources.
• The use of heavily laid or textured paper will
seriously affect the life of the image drum and give
poor print quality. Print quality can be improved by
changing the media setting to ‘Ultra Heavy.’ However, this
will reduce the output speed and prevent the use of the
duplex option.
If the Ultra Heavy setting does not give proper toner
fusion, you can try the Label settings.

• Avoid:
- Damp, damaged or curled paper.
