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 
machine’s 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  or greater curl may cause jams 
to occur.
• 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 
they may damage your machine. This 
damage is not covered under any Brother 
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 Manual 
feed slot. 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 the 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/LED 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 below
 
• with each side folded as shown below
 
If you use any of the types of envelopes 
listed above, they may damage your 
machine. This damage may not be 
covered under any Brother 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 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 must be fed from the manual feed slot 
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.

Using the automatic 
document feeder (ADF)2
The ADF can hold up to 35 pages and feeds 
each sheet individually. Use standard 80 gsm 
paper and always fan the pages before 
putting them in the ADF.

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 with the ADF. Instead use the 
scanner glass.
• To avoid damaging your machine while  using the ADF, DO NOT pull on the 
document while it is feeding.
