• Loading Paper
Unpacking
Injury may result.
Lift this machine by 2 persons, because it weighs approximately 40 kg.
• Be sure to use the consumables or maintenance units provided with this printer at first. Otherwise, the life of the
consumables or maintenance units may not be displayed correctly, or you may not be able to use them later.
• Use extra care when handling the image drum (the green cylinder), because it is fragile.
• Do not expose the image drum to direct sunlight or strong light (approximately 1,500 lux or more). Even under room
lighting, do not leave the image drum for 5 minutes or more.
• Packaging and cushioning materials are required for transporting the machine. Do not dispose of it, and keep it for
future use.
Remove the machine from the box, and then remove all cushioning materials

*1 Use paper that meets the following conditions:
- Paper that meets the conditions for plain paper.
- An ink used for a part printing is heat resistant (230°C).
• When specifying a printing area, please take into account the differences of printing position as followings:
Print start position: ±2 mm, Paper skew: ±1 mm/100 mm, Image stretch: ±1 mm/100 mm (when paper ream weight
is 70 kg)
• This printer cannot print on an ink.
*2 Use paper that meets the following conditions:
- A pigment or an ink used to color paper is heat resistant (230°C).
- Paper that has same characteristics with light paper.
- Paper used for an electronic photo printer.
•Labels
Labels must 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 stocks may damage the
machine due to the labels peeling off during the printing process.
• Paper storage
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)
Do not store paper in the places as shown below:
• Directly on the floor
• Where paper is exposed to direct sunlight
• Near the inside of an exterior wall
• On an uneven surface
• Where static electricity may be generated
• Where temperature excessively rises high and temperature rapidly changes
• Near this machine, an air conditioner, a heater, or duct
• Paper Recommendations
The machine supports a variety of print media, including a range of paper weights
and sizes. This section describes how to choose and use media. To obtain the best
2
performance, use 75 to 90 g/m
plain paper that is 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 must be free from twists, curls or other deformations. The envelopes must also
be of the rectangular flap type, with glue that remains intact when subjected to hot roll
pressure fusing in the machine. Window envelopes are not suitable.
• Do not unwrap paper until just before you use.
• Do not leave paper unwrapped for a long period. Doing so may result in printing problems.
• Depending on the print media, environment, storage conditions, the print quality may deteriorate or printout may get
curled.

• Network communication is Not stable
Cause Solution Reference
RSSI is low.
* Refer to as shown above.
The frequency band you are using is
congested.
* Refer to as shown above.
The received signal strength is weak.
Install this machine in a place with a
good view of the wireless access
point. (We suggest that the distance
between the machine and the wireless
device be 30 m or less.)
Do not place any electric appliances
that emit weak radio waves (such as
microwaves or digital cordless
telephones) close to the machine.
If there is metal, aluminum sash, or a
reinforced concrete wall between the
machine and wireless access points,
connections may be harder to be
established.
When [Band] is 2.4 GHz and the
wireless LAN access point supports 5
GHz, change to the 5 GHz SSID.
When [Band] is 5 GHz, change the
wireless LAN access point to be
connected to 2.4 GHz SSID.
