The bottom edge of the developer seal for the above lot production of
developer cartridge can have small scratch at edge of seal.
There is a possibility that broken the developer seal at the middle position if
followed the way which is mentioned in the instruction manual.
If the developer seal is not removed completely and used it, enough toner
will not be supply into the developing unit and can cause of miss-coloring.
To prevent this error, remove the developer seal by performing the following
way.
○
1
Hold the developer seal at the green label part, and pulled the
developer seal slowly on the straight (about 20 cm).
Don't pull more than 20 cm position at this stage.
Don't pull more than 20 cm position at this stage.
○
2
Twist the green label of the developer seal counter-clockwise
one full rotation. This process will turn the damaged edge of
the developer seal inwards, preventing friction with the
developer unit case and reducing the force to seal.
○
3
Refer to the figure below and slowly pull the developer seal at
about a 30 degree angle. This process will prevent friction
between edges of the developer seal and developer unit case.
6) Close the lock cover of the developer cartridge.
