1.Model Name:
  MX-6201N/7001N, MX-701FU/701FU1/701FU2, MX-701HK/701LH
2.Symptom:
Depending on the installation environments or the type of copy paper used, the rotation of the
roller after paper has passed the fusing unit sometimes causes damage on the rear side of the
upper heat roller. This is influenced by the condition of the pressure generated between the
upper and the lower heat rollers when paper passes the fusing unit, this occurs when on
standby between jobs, or at the waiting time of paper feeding in the multi-printing mode.
3.Description:
We changed the shape of the cored bar in the lower heat roller. This disperses the pressure
applied to the upper heat roller and thereby makes it more difficult to damage the rear side of
the upper heat roller.
Cored bar shape modification
Distinguishing the new and old lower heat rollers
