Acceptable paper and 
other print media
2
Print quality may vary according to the type of 
paper you are using.
You can use the following types of print 
media: thin paper, plain paper, thick paper, 
bond paper, recycled paper, transparencies, 
labels or envelopes.
For best results, follow the instructions below:
Use paper made for plain paper copying. 
Use paper that is 60 to 105 g/m
2.
Use labels and transparencies which are 
designed for use in laser machines.
DO NOT put different types of paper in the 
paper tray at the same time because it 
may cause paper jams or misfeeds.
For correct printing, you must choose the 
same paper size from your software 
application as the paper in the tray.
Avoid touching the printed surface of the 
paper immediately after printing.
When you use transparencies remove 
each sheet immediately to prevent 
smudging or paper jams.
Use long grain paper with a neutral Ph 
value, and a moisture content of approx. 
5%.
Recommended paper and 
print media2
To get the best print quality, we suggest using 
the following paper.
Type and size of paper2
The machine loads paper from the installed 
standard paper tray, optional lower tray or 
multi-purpose tray.
Standard paper tray2
Since the standard paper tray is a universal 
type, you can use any of the paper sizes (one 
paper type and size at a time) listed in the 
table in Paper capacity of the paper trays 
on page 13. The standard paper tray can 
hold up to 250 sheets of Letter/A4 size paper 
(80 g/m
2). Paper can be loaded up to the 
maximum paper mark on the sliding paper 
width guide.
Multi-purpose tray (MP tray)2
The MP tray can hold up to 50 sheets of plain 
paper (80 g/m
2) or up to 3 envelopes. Paper 
can be loaded up to the maximum paper mark 
on the sliding paper width guide.

Handling and using special 
paper2
The machine is designed to work well with 
most types of xerographic and bond paper. 
However, some paper variables may have an 
effect on print quality or handling reliability. 
Always test samples of paper before 
purchasing to ensure desirable performance. 
Store paper in its original packaging and keep 
it sealed. Keep the paper flat and away from 
moisture, direct sunlight and heat.
Some important guidelines when selecting 
paper are:
Do not use inkjet paper because it may 
cause a paper jam or damage your 
machine.
Preprinted paper must use ink that can 
withstand the temperature of the 
machines fusing process (200 degrees 
centigrade).
If you use bond paper, paper having a 
rough surface or paper that is wrinkled or 
creased, the paper may exhibit degraded 
performance.
Types of paper to avoid2
IMPORTANT
Some types of paper may not perform well 
or may cause damage to your machine.
DO NOT use paper:
• that is highly textured
• that is extremely smooth or shiny
• that is curled or warped
 
12mm
• that is coated or has a chemical finish
• that is damaged, creased or folded
• that exceeds the recommended weight 
specification in this guide
• with tabs and staples
• with letterheads using low temperature 
dyes or thermography
• that is multipart or carbonless
• that is designed for inkjet printing
If you use any of the types of paper listed 
above, they may damage your machine. 
This damage is not covered under any 
KONICA MINOLTA warranty or service 
agreement.

Envelopes2
Most envelopes will be suitable for your 
machine. However, some envelopes may 
have feed and print-quality problems 
because of the way they have been made. A 
suitable envelope should have edges with 
straight, well-creased folds and the leading 
edge should not be thicker than two sheets of 
paper. The envelope should lie flat and not be 
of baggy or flimsy construction. You should 
buy quality envelopes from a supplier who 
understands that you will be using the 
envelopes in a laser machine.
Envelopes can only be fed from the MP tray. 
Do not print envelopes using duplex printing. 
We recommend that you print a test envelope 
to make sure the print results are what you 
want before you print or purchase a large 
quantity of envelopes.
Check the following:
Envelopes should have a lengthwise 
sealing flap.
The sealing flaps should be folded crisply 
and correctly (irregularly cut or folded 
envelopes may cause paper jams).
Envelopes should consist of two layers of 
paper in the area circled in figure below.
 
1 Feeding direction
Envelope joints that are sealed by the 
manufacturer should be secure.
We recommend that you do not print 
within 15 mm of the edges of envelopes.
Types of envelopes to avoid2
IMPORTANT
DO NOT use envelopes:
• that are damaged, curled, wrinkled or 
an unusual shape
• that are extremely shiny or textured
• with clasps, staples, snaps or tie 
strings
• with self-adhesive closures
• that are of a baggy construction
• that are not sharply creased
• that are embossed (have raised writing 
on them)
• that were previously printed by a laser 
machine
• that are pre-printed on the inside
• that cannot be arranged neatly when 
stacked
• that are made of paper that weighs 
more than the paper weight 
specifications for the machine
• with edges that are not straight or 
consistently square
• with windows, holes, cut-outs or 
perforations
• with glue on surface as shown in figure 
below
 
• with double flaps as shown in figure 
below

• with sealing flaps that have not been 
folded at purchase
• with sealing flaps as shown in figure 
below
 
• with each side folded as shown in 
figure below
 
If you use any of the types of envelopes 
listed above, they may damage your 
machine. This damage is not covered 
under any KONICA MINOLTA warranty or 
service agreement.
Occasionally you may experience paper 
feed problems caused by the thickness, 
size and flap shape of the envelopes you 
are using.
 
Labels2
The machine will print on most types of labels 
designed for use with a laser machine. Labels 
should have an adhesive that is acrylic-based 
since this material is more stable at the high 
temperatures in the fuser unit. Adhesives 
should not come in contact with any part of 
the machine, because the label stock may 
stick to the drum unit or rollers and cause 
jams and print quality problems. No adhesive 
should be exposed between the labels. 
Labels should be arranged so that they cover 
the entire length and width of the sheet. Using 
labels with spaces may result in labels 
peeling off and causing serious jams or print 
problems. 
All labels used in this machine must be able 
to withstand a temperature of 392 degrees 
Fahrenheit (200 degrees centigrade) for a 
period of 0.1 seconds.
Label sheets should not exceed the paper 
weight specifications described in this User’s 
Guide. Labels exceeding this specification 
may not feed or print correctly and may cause 
damage to your machine.
Labels can be fed from the MP Tray only.
Types of labels to avoid2
Do not use labels that are damaged, curled, 
wrinkled or an unusual shape.
 
IMPORTANT
DO NOT feed part used label sheets. The 
exposed carrier sheet will damage your 
machine.

document feeder (ADF)2
The ADF can hold up to 50 pages and feeds 
each sheet individually. Use standard 
80 g/m
2 paper and always fan the pages 
before putting them in the ADF.

IMPORTANT
• DO NOT leave thick documents on the 
scanner glass. If you do this, the ADF may 
jam.
• DO NOT use paper that is curled, 
wrinkled, folded, ripped, stapled, paper-
clipped, pasted or taped.
• DO NOT use cardboard, newspaper or 
fabric.
• To avoid damaging your machine while 
using the ADF, DO NOT pull on the 
document while it is feeding.

Note
• When loading the documents in the ADF 
and MP>T1>T2 or T1>T2>MP is selected, 
the machine looks for the tray with the 
most suitable paper and pulls paper from 
that tray. If no tray has suitable paper, the 
machine pulls paper from the higher 
priority tray.
• When using the scanner glass, your 
document is copied from the higher 
priority tray even if more suitable paper is 
in another paper tray.
