Connection with a Computer (Option)
With an optional interface card (RISO PC Interface Card USB 2.0) installed, you can directly send data from a con-
nected computer to the machine as an original for printing. Because digital data itself is used for making a master, the
finish of prints becomes outstanding.
Important!:
• The maximum allowable voltage for USB 2.0 connector input and output is 5 V.
• Use a commercially available USB cable (that conforms to the USB 2.0 standard / Length within 3m (10ft)).

Paper Recommendations
10
Paper Recommendations
Size and Weight Restrictions
The table shows the specifications of usable print paper.
Important!:
• Be sure to load printing paper larger than the images to be created. If printing paper is smaller than the images, the
inner rollers may be stained and it may result in smudges on the prints.
• Be sure to confirm the maximum printing area and margins before printing ()p.12).
• Even when using paper whose sizes and weights are supported by the machine, 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 50 g/m2(14-lb bond))
• Extremely thick or heavy paper (greater than 128 g/m2(34-lb bond))
• Wrinkled, curled, folded, or torn papers
• Chemically treated paper (such as thermal or carbon paper)
• Paper coated on its face or back surface
• Paper having a sticky section or holes (such as an envelop and label paper)
Note:
• Paper with a horizontal grain direction can cause problems with paper feeding. Use paper with a vertical grain
direction.
• Images are not output onto the entire area of usable print paper.
If paper with a size exceeding the limit of specifications is used, the paper feeding and print quality on such paper are
not warranted.

Paper Recommendations 11
Tips for Better Paper Feeding
To prevent paper jams and misfeeds, follow the directions below:
• Set the Paper Feed Pressure Adjustment Lever to the position according to the thickness of the printing paper.
()p.20)
Standard paper: Standard position 1 ( 1), Standard position 2 ( 2)
Thin paper: Thin paper ( )
Thick paper (such as card stock): Thick paper ( )
• Adjust the position of the Paper Jump Wing according to the size of the printing paper. ()p.22)
• Always set the Feed Tray Paper Guide and the Receiving Tray Paper Guide according to the print paper
size.()p.20)
• Use flat printing paper that is free of folds. If the use of curled paper is unavoidable, place the printing paper so that
the curl faces down.
• Paper may stick to the Print Drum (Cylinder) surface if the top margin is too narrow on the original or if the upper
portion of the original 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. Restart master making and printing from the beginning
when you rotate the original.
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 the printing paper, keep the remaining paper wrapped and store it in a moisture-proof box. It is highly
recommended to put silica gel in the paper storage box.

Originals
Size and Weight Restrictions
Usable originals are as follows.
• The maximum printing area is 249 mm × 352 mm ( 8 3/16" ×13 17/32" ). If the original image size is larger than this
limit, you need to reduce the original when making a master.
Note:
• When printing the following kinds of originals, copy to paper of an available size.
– 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(14-lb bond))
• You cannot use the following originals on this machine.
– Multi-layered originals, or multiple originals stapled or clipped
– Extremely thick originals (greater than 107 g/m2(28-lb bond))
Maximum Printing Areas and Margins
The maximum printing areas are as follows.
The maximum printing area is read and the originals are printed regardless of the original size and the paper size in
the printer.
No matter which size of originals, be sure to make some margins around the original. Especially a 10 mm (3/8") mm
margin on the top side is required for originals. The printing area that is larger than print paper stains the Pressure
Roller and smudges the paper.

Originals 13
Important!:
• A 10 mm (3/8") margin on the top side cannot be read when a master is made. If any letter is placed in the margin,
a master cannot be made.
• If the original area is larger than the print paper, always reduce the original to fit it inside of the margins.
• If the printing paper sticks to the Print Drum (Cylinder) or if you find a blur in a 10 mm (3/8") position from the top
end, move the print position towards the bottom end.
Materials Not to Be Printed
Do not use the machine in any manner which violates the law or infringes on established copyrights, even when
making copies for personal use. Consult your local authorities for further details. In general, use discretion and
common sense.
