No Ink Cartridge error
[Occurrence Condition]
This error occurs when Ink
Cartridge is not installed.
[Major Occurrence Timing]
• Power-on timing
[Troubleshooting]
• Ink Cartridge installation
Paper Jam Fatal error
[Occurrence Condition]
This error occurs when CR Unit is
blocked by jammed paper.
[Major Occurrence Timing]
• Power-on timing
[Major Troubleshooting]Åz
• Remove jammed paper
?On this product, if CR Unit
touches jammed paper, CR Unit
moves back in the opposite
direction so that customer can
remove the paper. However, if CR
Unit cannot move in this
sequence, this error occurs.
Paper Jam error
[Occurrence Condition]
This error occurs when top/
bottom of paper is not detected by
PE Sensor in the specified steps of
paper loading / ejecting operation
correctly.
[Major Occurrence Timing]
• Power-on timing
• Paper loading timing
• Paper eject timing
[Major Troubleshooting]
1 Perform paper eject operation
from operation panel.
• Success
Starts paper feeding
operation again if printer has
print data.
•Fail
Occurs paper jam error
again.
2 If fail in the above 1, remove
the paper by opening Scanner
Unit.
3 Perform paper eject operation
from operation panel again.
• Success
Starts paper feeding
operation again if printer has
print data.
•Fail
Occurs paper jam error
again.
4 Check the following if failed in
Step 3.
• Foreign object
• Detached parts
• PE Sensor Lever
• PE Sensor
• Porous Pad on Paper Guide
Front
• Main board
No Paper error
[Occurrence Condition]
This error occurs when top of
paper can not be detected
correctly by PE Sensor in the
specified steps up to completion
of the paper loading operation.
(No paper / No loading / large
paper skew)
[Major Occurrence Timing]
• Paper loading timing
[Major Troubleshooting]
1 Set paper in ASF and perform
paper feed operation.
2 If the paper stops before
reaching PE Sensor, remove it
and check the paper condition.
3
A)
If paper is OK, set paper in
ASF and move edge guides to
appropriate position, and
perform 2 again.
B)If damage in the above 2,
check foreign materials / parts
come-off / parts transformation
in paper path.
4 If the problem is not solved by
3-A) & 3-B), check the
following.
• Foreign object
• Detached parts
• Surface condition of LD
Roller or PF Roller
• PE Sensor Lever
•PE Sensor
• Main Board
•PF Motor
Double Feed error
[Occurrence Condition]
When manual duplex printing is
selected using the printer driver,
this error occurs if the actual
paper length detected by PE
Sensor does not match with the
paper length specified in the
printer driver. (The error occurs
when the actual length is longer
than the theoretical length
specified in the driver.)
[Major Occurrence Timing]
• Paper loading timing
• Paper eject timing
[Troubleshooting]
• PE Sensor Lever replacement
• PE Sensor replacement
(Main Board replacement)
• Main Board replacement
?This error may occur in the
manual duplex printing if the
inverted sheet printed on the first
side sticks to the second sheet
when the first side printing is
complete and the sheet is inverted
and set to ASF to print on the
other side.
No Power

*: If the printer can turn on but turns off right away, the protection
circuit may cut off the power due to an error such as a circuit
failure.
The power-on sequence
does not start
(p 10)
Paper Size Unmatch error
[Occurrence Condition]
This error occurs if the actual
paper length detected by PE
Sensor does not match with the
paper length specified in the
printer driver. (The error occurs
no matter when the actual length
is longer or shorter than the
theoretical length specified in the
driver.)
[Major Occurrence Timing]
• Paper eject timing
[Troubleshooting]
• PE Sensor Lever replacement
• PE Sensor replacement
(Main Board replacement)
• Main Board replacement
