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.
Labels
2
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 properly and may cause 
damage to your machine.
Labels must be fed from the manual feed slot 
only.
Types of labels to avoid
2
Do not use labels that are damaged, curled, 
wrinkled or an unusual shape.
IMPORTANT
Avoid feeding labels with the carrier sheet 
exposed because your machine will be 
damaged.
