Paper Recommendations
Loading Paper
❒Do not use ink-jet printer paper because it may stick to the fusing unit and
cause a paper misfeed.
❒When printing on OHP transparencies that have a print side, load them with
the print side over on the bypass tray. Not taking this precaution may cause
them to stick to the fusing unit and cause misfeeds.
❒Set the paper as described below
• Tray 1: Print side facing down
• Bypass Tray: Print side facing up
• Paper Feed Unit (Tray 2, Tray 3): Print side facing down
❒Print quality cannot be guaranteed if paper other than the ones recommended
is used. For more information about recommended paper, contact your sales
or service representative.
❒Do not use paper that has already been printed onto by other printers.
Storing Paper
• Paper should always be stored properly. Improperly stored paper might result
in poor print quality, paper misfeeds, or printer damage. Recommendations
are as follows:
• Avoid storing paper in humid areas.
• Avoid exposing paper to direct sunlight.
• Store on a flat surface.
• Keep paper in the package in which the paper came.

Envelopes
Paper not supported by this printer
Avoid using the following paper as they are not supported by this printer.
• Paper meant for an ink-jet printer
• Bent, folded, or creased paper
• Curled or twisted paper
• Torn paper
• Wrinkled paper
• Damp paper
• Paper that is dry enough to emit static electricity
Additional cautions • Print speed for OHP transparencies is slower than for plain pa-
per.
• Due to switching modes, the machine will be on standby for
thirty or forty seconds after the job was received.
Printer setup Press [Paper Input]menu, [Paper Type], and then press [Thick Paper]
on the control panel.
❒The paper type selected using the printer driver overrides that

❒Make sure paper is not stacked higher than the upper limit
mark (T) inside the tray. Make sure paper is not stacked higher
than the paper guides inside the bypass tray.
Both-sided printing Not possible
Additional cautions • Check the print side is facing up.
• Check there is no air in the envelopes before loading.
• For better print quality, we recommend the right, left, top, and
bottom print margins to be at least 20 mm (0.8”) each.
• Load only one size and type of envelope at a time.
• Before loading envelopes, flatten their leading edges (the edge
going into the printer) by running a pencil or ruler across them.
• Some kinds of envelope might cause misfeeds, wrinkles or
print poorly.
• Print quality on envelopes may be uneven if parts of an enve-
lope have differing thicknesses. Print one or two envelopes to
check print quality.

Paper and Other Media
13
• Paper that has already been printed onto, except a preprinted letterhead
Malfunctions are especially likely when using paper printed on by other than
a laser printer (e.g. monochrome and color copiers, ink-jet printers, etc.)
• Special paper, such as thermal paper, aluminum foil, carbon paper and con-
ductive paper
• Paper whose weight is heavier or lighter than the limitation
• Paper with windows, holes, perforations, cutouts, or embossing
• Adhesive label paper on which glue or base paper is exposed
• Paper with clips or staples
• Envelopes in the following conditions:
•damp
• excessively curled or twisted
• stuck together
• damaged in any way
• with stamps attached
• with windows, holes, perforations, cutouts or embossing
• with metal clasps, string ties or metal folding bars
• designed to be interlocked
• with nicked edges or bent corners
• with rough, wrinkled or laid finishes
• with any exposed adhesive, when the flap is in the sealed or closed posi-
tion

Loading Paper
This describes how to load paper into the paper tray and bypass tray.
Loading Paper in Tray 1 and the optional paper feed unit
The following example explains loading procedure for the standard paper tray
(Tray 1). The same procedure can be used for the optional paper feed unit.
❒Make sure paper is not stacked above the limit mark inside the tray. Misfeeds
might occur.
❒Do not put different types of paper in a single paper tray.
❒Up to 500 sheets of paper can be loaded in the paper feed unit. This means
a maximum of 1,600 sheets can be simultaneously loaded when two addition-
al paper feed units are installed.
ALift the paper tray slightly, and then pull it out until it stops.
BLift the front side of the tray, and then pull it out of the printer.
•Do not pull out the paper tray forcefully. If you do, the tray might fall and
cause an injury.

Paper and Other Media
17
CLoad paper into the tray with the print side down.
❒Confirm that the top of the stack is not higher than the limit mark inside the
tray.
❒Confirm that paper fits under the rear guide.
DLift the front of the tray, and then slide it carefully into the printer until it
stops.
❒Do not slide the paper tray in with force. If you do, the front and side guides
might move.
For more information about type, size and feed direction of paper that can
be loaded in the tray, see p.5 “Paper and Other Media Supported by This
Printer”.
When you change the paper size see p.18 “Changing the paper size”.

Paper and Other Media
18
Changing the paper size
❒Confirm that the setting of the paper size dial matches the paper size and feed
direction of the paper in the tray, otherwise the printer might be damaged, or
printing problems might occur.
The following explanation uses the example of “Tray 1” for the paper tray.
ALift the paper tray slightly, and then pull it out until it stops. Adjust the
paper size dial to match the size and feed direction of paper in the paper
tray.
❒If you want to use the paper size and feed direction that are not indicated
on the paper size dial, set the dial to “p”. In this case, you should set the
paper size using the control panel.
BLift the front side of the tray, and then pull it out of the printer.
CIf you load paper larger than A4K, you should extend the tray as fol-
lows:
❒You cannot load paper smaller than A4K, if the tray is extended. In this
case, return the tray to its standard length.

Paper and Other Media
19
DSlide the catches inwards to unlock the tray.
ESlide the tray until it stops.
FReturn the catches to their original positions.
❒Confirm that the catches return to their original positions securely. If they
are not locked securely, paper misfeeds might occur.

Paper and Other Media
20
GAdjust the rear and side guides to the paper size you want to load.
❒To avoid damage, pinch the paper guides when moving them.
HLoad paper into the tray with the print side down.
❒Confirm that the top of the stack is not higher than the limit mark inside the
tray.
❒Confirm that paper fits under the rear guide.
