Rear Stacker (face up), Capacity100 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 in conjunction 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.

MEDIA TYPES
Paper
The best performance is obtained when using paper designed for use
in copiers and laser printers. Suitable types include:
•Hammermill®Laser Printer Radiant White, 24 lb. US Bond (90
g/m²)
•Xerox®4024, 20 lb.US Bond (75 g/m²)
•Oki®52206101 Bright White Proofing Paper, 32 lb. US Bond
(120 g/m2)
Recommendations
•Check http://my.okidata.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.
•Avoid:
– Damp, damaged or curled paper.
– Very smooth, shiny or glossy paper.
– Heavily embossed letterhead paper, very rough paper or paper
that has a large grain difference between the two sides.
– Paper with perforations, cut-outs or ragged edges.
– Carbon paper, recycled paper, NCR paper, photosensitive
paper, pressure sensitive paper or thermal transfer paper.

C5100 Media Recommendations • 13
Envelopes
•Use only recommended envelopes (Oki 52206301 and 52206302:
see “Selecting/Using OKI Print Media“ in your C5100 Handy
Reference Guide for more information).
•Envelopes should be stored flat and away from moisture, direct
sunlight and heat sources.
•Don’t use envelopes with windows or metal clasps.
•Don’t use damp, damaged or curled envelopes.
Transparencies
•Use only recommended transparencies (3M CG3720, Oki
52205701).
•Avoid office transparencies designed for use by hand with marker
pens. These will melt in the fuser and cause damage.
CAUTION
Print media must be able to withstand 446°F (230°C) for 0.2
second.
Yes No

C5100 Media Recommendations • 14
Labels
•Avery 5161 White Laser Labels (letter size) work well with your
printer. Check http://my.okidata.com for the latest information on
media for your printer.
•Use only labels designed for use in color laser printers and
photocopiers.
CAUTION!
• Labels should cover the entire carrier sheet.
• Carrier sheet or adhesive must not be exposed to any
part of the printer

Auto Switching
If you have identical paper stock loaded in the Multi-Purpose Tray or
the optional Second Paper Tray, you can have the printer
automatically switch to the other tray when the current tray runs out of
paper. This function is enabled in the Print Menu. (See page 72.)
MEDIA: MULTI-PURPOSE TRAY
Use the Multi-Purpose (MP) Tray for printing card stock, labels,
envelopes and transparencies. Or load a stack of letterhead
stationery to switch to as needed.
•A stack of media about 3/8'' (10 mm) high can be loaded into the
MP Tray, equivalent to about 10 envelopes or 50 transparencies.
•Media should be loaded print side up, top edge facing into the
printer.
•Generally, the rear exit (Face Up Stacker) is used with the MP
Tray.
Important!
The duplex unit can be used for paper only, at weights up to 28
lb. US Bond (105 g/m2metric, 58 lb. Index). Do not use the
duplex (two-sided printing) function for labels, envelopes,
transparencies, or paper heavier than 28 lb. US Bond.
