*1 How to Clean the Development Roller Gap
Clean the doctor blade with a special jig.
DG CLEANER 5PCS/SET[A]: Bent part for cleaning to the right
[B]: Bent part for cleaning to the left
[C]: Guide hole
Remove PCDU.
Remove the Entrance seal [A] (
x3)
Watch the drive gear [A] from the back of the unit and turn it counterclockwise until the developer on top of the development roller runs out.
When there is developer inside, keep the development unit level while working.
Insert the flat side of the special jig into the doctor with the bent part [A] facing up as shown below.
If the bent part gets caught, guide it with your finger and insert it all the way in.
To clean to the left, use the bent part that has the guide hole [B].
To clean to the right, use the other one.
Gently draw the jig towards you and with the bent part caught on the back side of the doctor [A], slide it toward the left side [B] and clean it out.
Change how it is facing and slide it back and forth several times.Tilt the jig at an angle and withdraw it from where the part is not bent.
To clean to the right, use the jig that faces the opposite way and follow the same steps.
Only move the jigs left/right except when attaching or removing them; do not apply excessive force on them up/down (front/back). (To prevent breaking or damage to the bent part and from scratching the surface of the development sleeve.) Also, take care not to rub hard on the surface of the sleeve.
