8. Remarks
• When the machine is on and the power source is less than 90% of the specified amount, printing
quality will decrease. Therefore, make sure the supply from your electrical outlet is at least 90% of
the required amount.
• When you make a lot of prints from a small image, ink might ooze out from the edges of the
master, especially in high temperatures and when printing in two or more colors. In these cases,
make a new master.
• Remove the paper from the tray before relocating the machine. If you relocate the machine leaving
the paper on the tray, reset the paper after the relocation. If the main switch of the machine is
turned on without resetting the paper correctly, the sensor might be broken.
• If the printed paper is stored for more than one day, the paper may become wrinkled. If this paper
is used, wrinkles may also appear on the master. If the paper will be stored for more than one day,
store it in its original wrapping paper or other protective covering.
• Shadowing may occur if the printed image at the rear edge of the paper is a solid color, when the
printing speed is set to 1. If this occurs, print the image with the printing speed set to 3.
• If there are fine lines within 5 mm to 10 mm (0.2 to 0.4 inches) of the edge of the image,
shadowing may occur.
• Depending on the type of paper being used, speckles may appear within 5 mm to 10 mm (0.2 to
0.4 inches) of the edge of the image at around 1,000 prints.
• When two or more sheets of paper feed at once, you can select whether the warning message is
displayed or not. Set to [On] of the "Double Feed Warning" with User Tools. For details, see
page 149 "System Settings".
• When two or more sheets of paper feed at once, set paper on the paper feed side plates securely.
For details, see page 35 "Preparations for Printing".
• When paper misfeeds occur, select the proper paper type from [Feed Tray Paper Type]. For
details, see page 149 "System Settings". If the problem persists, fan or turn the paper over.
• If the paper skews, make sure to set the paper feed side plates securely. For details, see page 35
"Preparations for Printing".
• Make sure originals on the exposure glass are correctly positioned and aligned with the scale.
• If the edges of the paper are rounded, skewing might occur. Change the paper's orientation or
replace.
• If the paper becomes creased, check that the correct paper type is selected in [Feed Tray Paper
Type]. For details, see page 149 "System Settings".
• If custom paper crease frequently, use the standard paper type.
• Burrs on the end face of the paper may damage the master surface and leave scratches on it. If you
continue using the same master for printing, the scratches may result in ink spots on or around the
edge of the paper. If this is the case, place the paper upside down, and then create the master
again.
