Description
The 1050 'hard roller' versus the 'soft roller'.
Solution
The 'hard rollers' provide high quality output. Based on field test accounts for the bizhub PRO 1050, for most applications the 'hard rollers' are more than
acceptable. The 'soft rollers' (Service Bulletin 5136) will provide enhanced quality on solids and halftones, which is what commercial printers are most
focused on.

Description
There are two types of Fuser Rollers -a hard roller which is standard and a soft roller which improves copy quality under certain circumstances.Depending on
the type of roller installed, a DIPSW needs to be set under the Service mode.
Solution
For a soft Fuser roller set DIPSW27, Bit 1 to ON. The roller can be identified by its pressure springs which are black (modified springs are also black).
For a hard Fuser roller set DIPSW27, Bit1 to OFF. The roller can be identified by its pressure springs which are gold (modified springs areblack).
