6.15.10 RADF Separation roller pressure force adjustment
(e-STUDIO557/657/757/857)
In some cases the life of the separation roller may be shortened or paper jams and multiple feeding
(E712, E721, E724) may occur regardless of the operation frequency of the equipment. This comes
from the weight or edge status of paper used and the amount of paper dust.
Generally paper jams and multiple feeding often occur as the life end of the roller approaches.
However, if they often occur even though its life has not yet reached its replacement timing, or if the life
end comes much earlier than the scheduled replacement timing, the jams and multiple feeding can be
suppressed by adjusting the pressure force of the separation roller.
In this method, however, when the roller life becomes longer, jams and multiple feeding may occur
frequently, and when the jams and multiple feeding are suppressed, the roller life may become shorter.
Therefore, perform this adjustment while checking the status carefully, and if necessary, give a
sufficient explanation to users.
