Printing Methods
• 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 may
not be covered under any Brother warranty or service agreement.
Labels
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
(392 degrees Fahrenheit) for a period of 0.1 seconds.
Types of labels to avoid
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.
• 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.
• DO NOT reuse or insert labels that have previously been used or is missing few labels on the sheet.
