							Printing and storage environment
Ideally, the printing and media-storage environment should be at or near room temperature,
and not too dry or too humid. Remember that paper absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate,
while cold causes it to condense on the sheets. Heating systems and air conditioners
remove most of the humidity from a room. As paper is opened and used, it loses moisture,
causing streaks and smudging. Humid weather or water coolers can cause the humidity to
increase in a room. As paper is opened and used it absorbs any excess moisture, causing
light print and dropouts. Also, as paper loses and gains moisture it can distort. This issue
can cause jams.
As a result, paper storage and handling are as important as the paper-making process itself.
Paper storage environmental conditions directly affect the feed operation and print quality.
Care should be taken not to purchase more paper than can be easily used in a short time
(about three months). Paper stored for long periods can experience heat and moisture
extremes, which can cause damage. Planning is important to prevent damage to a large
supply of paper.
Unopened paper in sealed reams can remain stable for several months before use. Opened
packages of paper have more potential for environmental damage, especially if they are not
wrapped with a moisture-proof barrier.
The media-storage environment should be properly maintained to ensure optimum device
performance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of
45% to 55%. The following guidelines are helpful when evaluating the papers storage
environment:
●Print media should be stored at or near room temperature.
●The air should not be too dry or too humid.
●The best way to store an opened ream of paper is to rewrap it tightly in its moisture-
proof wrapping. If the device environment is subject to extremes, unwrap only the
amount of paper to be used during the days operation to prevent unwanted moisture
changes.
●Avoid storing paper and print media near heating and air conditioning vents or near
windows and doors that are frequently open.

							Loading trays
Load special print media, such as envelopes, labels, and transparencies, in tray 1 only.
Note
Because tray 2 is not included for all models, it is referred to as optional tray 2 in this
documentation.
Loading tray 1
Tray 1 (the multipurpose tray) holds up to 125 sheets of paper or other print media, or it
holds up to 10 envelopes.
CAUTION
Avoid adding print media to tray 1 while the printer is printing, or jams can occur. Do not fan
paper before loading it into trays, and avoid overloading trays.
To load tray 1
1. Open tray 1.
2. Slide out the tray extender. If the print media being loaded is longer than 23 cm (9
inches), also open the additional tray extender.
3. Slide the media-width guides slightly wider than the print media.
4. Place print media into the tray with the side to be printed upon face-up, and the top,
short edge in first.
NoteIf you are manually duplexing, see Printing on both sides (duplexing manually) for loading
instructions.
28Chapter 4 Using the device ENWW
 
						

							5. Slide the media-width guides inward until they lightly touch the print media stack on both
sides without bending it. Make sure that the print media fits under the tabs on the media-
width guides.
CAUTIONWait for the printer to finish printing before closing tray 1. Closing the tray before the printer
finishes can cause jams.
6. On the back of the printer, lower the rear output door if you are printing on special
media, such as labels, envelopes, or heavy or light paper, to prevent curl.
CAUTION
Remove each page as it exits the device to avoid a jam error message.
Loading optional tray 2
Paper includes average-weight letterhead and prepunched paper. For additional information
about letterhead and prepunched paper, see 
Printing on special media.
CAUTION
Print on special print media such as labels and transparencies from tray 1 only. Printing on
special print media from optional tray 2 can cause jams. Do not fan paper before loading it
into trays, and avoid overloading trays.
To load optional tray 2
1. Pull optional tray 2 out of the printer and remove any paper.
2. Move the media-width guides to match the size of paper that you are loading. Optional
tray 2 accepts several standard paper sizes.
ENWWLoading trays29
 
						

							3. Extend the paper-length adjustment control at the rear of the tray until the arrow on the
markings on the tray points to the size that you are loading.
4. Load the paper. If this is special paper such as letterhead, load it with the side to be
printed upon face-down and the top edge toward the front of the tray.
Note
If you are duplexing manually, see Printing on both sides (duplexing manually) for loading
instructions.
5. Make sure that the stack of paper is flat in the tray at all four corners, and keep it below
the height tabs on the media-length guide in the rear of the tray. Push down on the metal
media-lift plate to lock it into place.
6. Slide the tray into the printer. If you set the rear of the tray to one of the longer sizes, the
back of the tray will protrude from the back of the printer.
Loading documents to scan
Use these instructions to load originals into your device for scanning. For the best quality
scans, use the flatbed scanner.
To load originals onto the flatbed scanner
1. Make sure that the automatic document feeder (ADF) contains no media.
2. Lift the flatbed scanner cover.
3. Place the original document face-down on the flatbed scanner with the upper-left corner
of the document at the lower-right corner of the glass.
4. Gently close the lid.
The document is ready to be scanned.
CAUTION
To prevent damaging the device, do not allow the scanner lid to fall onto the flatbed scanner
surface. Always close the scanner lid when the device is not in use.

							To load originals into the automatic document feeder (ADF)
NoteThe ADF capacity is up to 50 sheets of 75 g/m2 (20 lb) media.
The minimum size for media in the ADF is 127 by 127 mm (5 by 5 inches). For smaller sizes,
use the flatbed scanner. The maximum size for media in the ADF is 216 by 381 mm (8.5 by
15 inches).
1. Make sure that the flatbed scanner contains no media.
2. Close the flatbed scanner cover and put the top end of the stack of originals into the
ADF input tray, with the media stack face-up and the first page to be copied on top of the
stack.
CAUTION
To prevent damaging the device, do not use an original that contains correction tape,
correction fluid, paper clips, or staples. Also, do not load photographs, small originals, or
fragile originals into the ADF.
3. Slide the stack into the ADF until it does not move any farther.
The control panel displays the message Document Loaded.
4. Adjust the media guides until they are snug against the media.
5. The document is now ready to be copied.
