If Drum 1 is removed, and the print speed is high (150 ppm): Min. 257 mm ×364 mm (B4)
Important!:
• Even when using paper whose specifications are supported size and weight, it may not pass through the machine
depending on such factors as paper finish, ambient conditions, and storage conditions. Keep this in mind when
using the machine. For more information, consult your dealer.
Do not use the following types of paper, as they can cause jams or misfeeds:
• Extremely thin paper (less than 46 g/m2)
• Extremely thick or heavy paper (greater than 210 g/m2)
• Wrinkled, curled, folded, or torn paper
• Chemically treated or coated paper (such as thermal or carbon paper)
• Paper having a sticky section or holes (such as an envelope and label paper)
Usable Printing Paper

Before Starting to Use
Paper Recommendations 15
Note:
• Paper with a horizontal grain direction can cause problems with paper pass. Use paper with a vertical grain direc-
tion.
• Images are not output onto the entire area of usable print paper. )p.17
RISO does not assure that paper outside the above specifications pass through the machine and can be used for
printing.
Tips for Better Paper Feeding
To prevent paper jams and misfeeds, follow the directions below:
• When using standard or light-weight paper, set the Paper Feed Pressure Adjustment Lever to “ ”. Then open
all four Paper Arrangers. )p.31, )p.33
• When using thick paper (such as card stock), set the Paper Feed Pressure Adjustment Lever to “ ”, and open
the two inner Paper Arrangers. )p.31, )p.33
• When using slippery paper, set the Paper Feed Pressure Adjustment Lever to “ ”. )p.31, )p.33
• Slide the Feed Tray Paper Guides, Receiving Tray Paper Guides, and Paper Stopper to fit the paper size. )p.31
• Use flat printing paper that is free of folds. If curled paper is unavoidable, place the printing paper so that the curl
faces down.
• Paper may stick to the drum surface if the top margin is too narrow on the original or if the upper portion of the orig-
inal uses a large amount of ink. To solve this problem, lower the print position to provide a wider top margin or
reverse the top and bottom of the original. Then restart printing from the beginning.
Storing Environment
Store printing paper in a level, dry area. Storing the paper in an excessively humid area can result in paper jams or
poor print quality.
After unpacking printing paper, keep the remaining paper wrapped and store it in a moisture-proof box. It is highly rec-
ommended to put silica gel in the paper storage box.

Before Starting to Use
Originals
16
Originals
Size and Weight Restrictions
Usable originals are as follows.
• Originals are scanned according to the size of paper placed on the Paper Feed Tray when masters are made; for
the same width, the positions of the Feed Tray Paper Guides.
When the placed paper is smaller than an original, not the entire original will be scanned.
When the placed paper is larger than an original, dirt on the glass or shade of the original, for example, may result
in unexpected dirt in the area beyond the size of the original.
• Bound originals can also be used on the Platen Glass.
• You can feed automatically up to 50 original sheets when using the optional ADF (Auto Document Feeder) unit.
Note:
• Use the Platen Glass when printing the following originals:
– Patched or worn originals
– Wrinkled, curled, folded, or torn originals
– Transparent originals (such as tracing paper or OHP transparencies)
– Chemically treated originals (such as thermal or carbon paper)
– Originals with correction fluid or glue
– Extremely thin originals (less than 50 g/m2)
– Extremely thick originals (greater than 128 g/m2)
– Heavy drawing paper
– Originals with staples or clips
• If an original is wrinkled, curled, or creased flatten it thoroughly so that the originals can be pressed directly onto
the Platen Glass during processing.
• If correction fluid or glue is used on an original, thoroughly dry it before placement.
• For an original patched with thick paper, the shade of the patched paper may also be printed.

Originals 17
Maximum Printing Areas and Margins
The maximum printing areas are as follows.
Important!:
• No matter which size of originals is printed, the margins indicated on the figure are required for the originals.
Reduce the original if necessary to fit it inside of the margins. Place an original so that its end having a 5 mm margin
at least comes to the left of the Platen Glass.
Tip:
About Printing Areas
• Printing area for the master is determined by the actual paper size detected on the Paper Feed Tray, regardless
of whether the original is being scanned, or sent from a computer.
• As shown in the illustration above, the printing area on the master will be smaller than the paper size (allowing 7mm
total margins for top and bottom, 6 mm for left and right). Peripheral areas in the original document exceeding the
printing area for the master will not be printed.
• The maximum printing area can be applied to the scanned image, regardless of the print paper size.
