• If the machine is not used for a long period, the image density might decrease
because the ink on the drum might dry. Make extra prints until the image
density recovers.
• When the machine is used in low temperature conditions, the image density
might decrease. In this case, slow the printing speed down to step 1 or 2.
• When making duplex prints, misdetection of paper wrapping might occur if
the paper delivery sensor detects a black area at the leading edge of the back
side. Keep at least an 5mm, 0.2" margin at the leading edge of the back side of
the printing paper.
• Press the
{
Proof
} key to perform a test print as the first few prints might be
light.
• The top sheet might remain between the feed rollers when you press the
{
Paste Shadow Erase
} key. In this case, remove the top sheet.
• When making duplex prints or when using non-white printing paper, the pa-
per end sensor might malfunction and fail to detect the paper. In this case,
place a blank sheet under the printing paper on the paper feed tray.
• The outer portion of the image might not be printed under low temperature.
In this case, slow the printing speed down to step 1 or 2, or increase the room
temperature.
• The paper exit pawl might contact the printing paper and cause black lines on
the prints. In this case, increase the printing speed or make a new master with
lighter image density mode.
• If you cannot pull out the drum, close the front cover again to rotate the drum.
Pull out the drum after it stopped at the position.
• The leading edge of the prints might become stained if the edge touches the
image of prints on the paper delivery tray.
• The ink of the print on the paper delivery tray might stick to the back side of
the next print.
• When the machine is on and the power source is less than 90 % of the speci-
fied amount, printing quality will decrease. Therefore, make sure the supply
from your electrical outlet is at least 90 % of the required amount.
• As various kinds and qualities of paper exist, some paper might be wrapped
around the drum or cause misfeeds.
• If your hands are stained with ink:
• Avoid prolonged or repeated contact with skin.
• Cleanse skin thoroughly after contact, before breaks and meals, and at the
end of the work period.
• Ink is readily removed from skin by waterless hand cleaners followed by
washing with soap and water.
• Also, be careful not to get any ink on your clothing while emptying the master
eject box or while loading a new ink cartridge.
