Paper Recommendations
Your MFP will handle a variety of print media,
including a range of paper weights and sizes.
This section provides general advice on choice of
media, and explains how to use each type.
The best performance will be obtained when
using standard 75~90g/m
2
paper designed for
use in copiers and laser printers.
Use of heavily embossed or very rough textured
paper is not recommended.
Pre-printed stationery can be used, but the
ink must not offset when exposed to the high
fuser temperatures used in the printing process.
 Envelopes
Envelopes should be free from twists, curls or
other deformations.
They should also be of the rectangular flap type,
with glue that remains intact when subjected to
hot roll pressure fusing used in this type of
printer. Window envelopes are not suitable.
 Labels
Labels should also be of the type recommended
for use in copiers and laser printers, in which the
base carrier page is entirely covered by labels.
Other types of label stock may damage the
printer due to the labels peeling off during the
printing process.
Storing Paper
Store paper under the following conditions to
maintain quality:
 Inside a cabinet or other dry and dark place
 On a flat surface
 Temperature: 20°C
 Humidity: 50% RH (relative humidity)
Avoid placing:
 Directly on the floor
 In the direct sunlight
 Near the inside of an exterior wall
 On an uneven surface
 Where static electricity may be generated
 Where temperature rapidly changes
 Near a printer, air conditioner, heater, or duct
Note
 Do not unwrap the paper until you are ready to use the
paper.
 Do not leave paper unwrapped for a long period. Doing so
may result in paper handling and print quality issues.
