1. Measure to prevent damage from occurring to the drawer connector in the drum
drive unit section.
1.Model Name: SF-2050
2.General: There was a problem of damage sometimes occurring to the drawer connector. The
damaged was caused because the insertion hole for the drawer connector of the DV

has been slightly enlarged. In addition to the change described above, a change has
been carried out in the shape of a portion of the attachment plate for the main PWB.
This change has been carried out as a measure to establish interchangeability between
the model listed above and other models.
