General Cautions
Make sure to make a few trial prints to check the image position because the
image position of the trial print might not correspond with that of the original.
If the image registration is not consistent, slow the printing speed down to
Setting 1 or 2.
When performing duplex or multicolored printing, leave the printed paper for
a while before the next printing in order to let the ink dry on the printed
paper. If this is not done, feed roller marks will appear on the print image.
If the machine is not used for a long period, the image density might de-
crease 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 may 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 may be
light.
The top sheet might remain between the feed rollers when you press the
Lower Paper Feed Table key. In this case, remove the top sheet.
When making duplex prints or when using non-white printing paper, the pa-
per size detection sensors might malfunction and some part of the image
might not appear on the print. In this case, place a blank sheet under the
printing paper on the paper feed table.
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 table.
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.
