(mm)
38 The attraction roller has a
fault:
• The engagement of the
attraction roller drive gear
2.7 is not proper.
• The attraction roller has
wear, deformation,
scratches, cracks,
vibration.
- The impact occurring when
the transfer blade hits the
connecting plate is
transmitted to the drum and
the bending mirror.
- Electrical interference
between the fixing roller
and the separation static
eliminator causes black
lines.
- A screw used to mount the
drum motor assembly to the
copier's rear side plate is
loose, letting the drum shaft
to tilt and, consequently,
causing wobbling when the
photosensitive drum rotates.
