10 Check that the foreign objects
including scrips, paper clips, etc.,
do not exist in the paper
conveying paths.
If foreign objects such as scrips, etc., remain in the paper conveying
path, remove.
11 Check that the paper conveying
guide and the separation needles
are not contaminated with toner,
paper dusts, etc.
If dirty, clean the guide, ribs (by a cloth), and the separation needles
(by a cleaning brush).If the ribs of the conveying guides were broken
or deposited with toner, replace.
12 Check that the paper conveying
guide has no barrs, deformations,
or abrasions; and it is properly
mounted without being floated.
Clean the conveying guide or the paper approaching guide.Remove
any protrusions including barrs.If floated, fix it properly.If deformation
or abrasion is observed, replace.
13 Check that the guide.
Check that the guide is smoothly
operative when manipulated.
If the guide is inoperative or won't operate smoothly, replace the
guide or the unit.
14 Check the action of the guide. If the guide is inoperative or won't operate smoothly, re-assemble the
guide or replace the solenoid or the unit.

15 Check the conveying rollers have
no paper dusts, toner, or foreign
objects stucked.Check a variation
of the external diameter of the
roller or abrasion is not observed
with the coveying roller.
Clean the conveying rollers or the pollyes.
If variation in the external diameter or abrasion is observed, replace.
16 Turn the cover safety switch and
check the motor and the clutch
are operated normally.
If the conveying motor or the clutch is inoperative, replace.

shaft are not contaminated.
Check that the spring has not
fallen off and is mounted so that it
is properly applying pressure
against the rollers or pulleys.
Clean the roller axle or the axle holder.Re-assemble it while checking
the pressure of the spring.
Sensor

smoothness due to an abnormal
move or dropping off of the
actuator of the coveying switch.
Re-assemble the actuator or the return spring.
19 Check that the surface of the
sensor and the recveptor black
felt pieces are not contaminated
with toner, paper dusts, etc.
If dirty, clean the sensor or the black felt piece.
20 Check the sensors are operated
normally.
If the sensor is inoperative, replace the switch.
Static
21 Check if the location is
susceptible to build static
discharge at the conveying guide
during printing.
Re-assemble and re-wire the static discharge sheet at the ejection
unit or the metal guide at the tranfer unit so that they are properly
grounded.
