Image Quality
Type 2
This type involves both of the following 2 factors.
A) Difference in the rotation speed of the ITB motor and registration motor causes difference in the
ITB rotation speed and the paper transport speed, which generates a shock and disrupts the image
transfer process at the PTR.
B) Depending on the type of paper in use the paper drags the ITB, which causes the ITB to rotate
slightly faster than the Bk drum. This disrupts the toner transfer from the Bk drum to the ITB.
As a result of the above, the image disrupted between the drum and ITB is transferred to the paper
at the PTR, which corresponds to the timing when the trailing edge passes through the registration
roller.
