Ricoh Priport DX 4545 Operating Instructions Manual page 144

Remarks
• When the machine is used in low temperature conditions, the image density
might decrease. In such a case, slow the printing speed down to Setting 1 or 2.
• When using paper which has printing on the reverse side, a black area on the
leading edge of the reverse side would cause the machine to mistake it for a
case of paper wrapping around the drum. Always keep a margin of at least
5mm, 0.2" on the leading edge of the reverse side.
• Press the {Proof} key to perform a test print as the first few prints might be
faint.
• When making duplex prints or when using printing paper that is not white in
color, the paper end sensor might fail to detect the paper correctly. In such a
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 Setting 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
a lighter image density.
• If you are unable to pull out the drum, close the front cover again to rotate the
drum. Pull out the drum after it has 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 reverse 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 can be readily removed from skin using waterless hand cleaners fol-
lowed by washing with soap and water.
• 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. To achieve the desired image quantity, 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 colors. In this case, make a new master.
• Use ink made within one year. Ink stored for a long period of time tends to
dry gradually and result in lower image density.
