Problem
Printed images are faint.
Printed texts are blurred.
Multi-up did not function.
There is nothing printed on
one side.
In the Book shadow editing,
the position for shadow
erasure is shifted.
Possible Cause
If the machine is not used for an
extended period of time, ink on the
surface of the Print Cylinder (Drum)
may dry. This results in faint or
blurred printing just after printing is
started.
Faint originals result in faint images.
If the temperature is low (below 59°F
(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.
Did you place the second original in
time after the beep, while the
message "Place Another Original and
Press Start Key" was showing?
Did you accidentally press the
key while the original was being
scanned?
Custom-size paper has been placed
on the Paper Feed Tray.
Custom-size book or magazine was
placed as an original.
The size of the original differs from
the Size of originals for Book shadow
editing specified using the Custom
Setting mode.
Troubleshooting
Action
The ink on the Print Cylinder (Drum) will
dry when the machine is not in use for an
extended period. Printing with dried ink will
produce light or faded copies.
Press the key and make several
copies before making copies to be actually
used. Or use the "Idling Action".
p.91
Increase the scanning level and perform
the master-making operation again.
p.45
For originals written with a pencil, select
the Pencil mode.
p.44
Use the machine after keeping it at room
temperature for a while.
p.8
With the "Ink Saving" mode selected, the
ink on printed copies is fainter than usual.
p.53
When you print using "Multi-Up", the
machine will beep during the Multi-Up
Interval. Place the second original during
that interval.
If the machine starts scanning for the
second time without a beep, even when
you are scanning from the Stage Glass,
you will need to adjust "Multiple-Original
Interval" settings on the Admin. screen.
p.100
The print operation will stop if the
is pressed while scanning is in progress.
Do not press the key until all originals
have been scanned.
The Book shadow editing does not allow
custom-size paper to be used.
Set standard-size paper.
Place a book or magazine on the Stage
Glass so that its binding section comes to
the center of the paper size placed on the
Paper Feed Tray (or the size specified for
the Size of originals for Book shadow
editing using the Custom Setting mode).
In the Book Shadow screen, select a Page
Size to be the same the original.
