J0508: No paper feed from the duplex section
Condition: Paper is not damaged (The duplex conveying drive does not rotate).
When feeding from duplex section, the registration sensor does not turn on after the exit solenoid turns on
(after paper switches back).
2 (In case paper is bent or
conveyed in skew) Check-
ing the conveying path
Paper is caught up by the
conveying guide or paper
piece.
If there is a paper piece or
foreign object on the convey-
ing side or a burr on the con-
veying side of the conveying
guide or on the parts such as
actuator, remove it or replace
it. If there is a scratch, defor-
mation or floating on the
sheet or film, correct or
replace it.
3 (In case paper leading
edge is bent) Checking
paper
The paper curls or is wavy. Replace the paper if it is
damp.
4 (In case paper slips and
stops at the DU conveying
roller) Checking paper
Unspecified papers are
used.
Explain to the user to use the
paper within the specifica-
tions.
5 (In case paper stops at the
DU conveying roller)
Checking the DU convey-
ing roller and pulley
The conveying perfor-
mance is lowered or slip-
page occurs (rotation not
smooth).
Clean the DU conveying
roller and DU conveying pul-
ley on their surface. Check
the pressure to the roller and
pulley and if the spring and
bushing come off, reattach
them. If the roller and pulley
are deformed or worn down,
replace them. If foreign
objects adhere to the drive
gear, remove them. If dam-
aged, replace it.
6 Checking the actuator and
the spring
The actuator does not
operate properly.
Reattach the actuator and
spring for the registration
sensor. If not operating prop-
erly due to deformation, cor-
rect or replace it.
