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 5 mm, 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.
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 specified
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.
The image density varies according to the printing speed and the room tem-
perature. So, adjust the printing speed or increase the room temperature.
When you make a lot of prints from a small image, ink might ooze out from
the edges of the master, especially under high temperature and when print-
ing in two or more colours. In this case, make a new master.
Use ink made within one year. Ink stored for a long period tends to dry slow-
ly and yield lower image density.
