Problem
The edges of printed copies are
smudged with ink.
The back of printed copies is
smudged with ink.
Printed images are faint.
Printed texts are blurred.
The left and right print positions have
been shifted.
Cause
Larger size of paper than the original
was placed on the Paper Feed Tray
at the time of the master-making
process.
When printing thick paper such as
cards, corners of the paper
contacted and damaged the master.
The Pressure Roller has been
stained with ink.
If the machine is not used for an
extended period of time, ink on the
surface of the Print Drum may dry.
This results in faint or blurred printing
just after printing is started.
Faint originals result in faint images. Increase the scanning level and
If the temperature is low (below
15°C) in a place where the machine
is installed or Ink Cartridges are
stored, ink does not flow smoothly.
The Ink Saving mode has been set.
The left and right print positions have
not been adjusted for the centre.
Troubleshooting
Action
Because a master was made
according to a larger size than the
original, the edges of the original
were processed as shadows. Set the
same size of paper as the original
and perform the master-making
operation again. Or attach tape as
described below to solve the
problem.
Make another master and print with
the new master. Or pull out the Print
Drum and attach cellophane tape to
the damaged section on the master.
However, if attached with cellophane
tape, a master may not been
properly sent to the Master Disposal
Box.
Remove the Print Drum and clean
the Pressure Roller. p.80
If the print position is outside the print
paper, this may cause the Pressure
Roller to be stained with ink.
Be careful when changing the size of
print paper or shifting the print
position.
Press the key and make several
copies before making copies to be
actually used. Or use the Idling
function. p.55
perform the master-making
operation again. p.37
For originals written with a pencil,
select the Pencil mode. p.33
Use the machine after keeping it at
room temperature for a while.
p.12
With the Ink Saving mode selected,
the ink on printed copies is fainter
than usual.
The Paper Feed Tray is equipped
with the Horizontal Print Position
Adjustment Dial. Lower the tray,
adjust the position, and then perform
proof copy to check the
position. p.46
