2-3. Separating Mechanism
The separating mechanism is more or less the same as the DF-520N.
The separating pressure can be set in seven steps from 0 to 6 to handle special coated paper. For this reason, the
separator base is located on the tilted plate to which it is connected by the link mechanism. When the separating
pressure adjusting dial is rotated, the tilted plate moves and forced pressure is applied to the separator base.
When the separating pressure scale value is standard “0”, the forced pressure is released, and only pressure of
spring C (approximately 120 g) is applied to the separator base.
When the separating pressure adjusting dial is rotated, forced pressure is applied to the separator base if the scale
value is within 3.5 (design value is 2.5).
Setting the separating pressure
When using normal paper, set the separating pressure to standard “0”, and increase 0.5 at a time if double-feed
occurs. For coated paper, set the separating pressure to “2.5 to 3.5”. However, first set to “2.5” and increase 0.5 at a
time if double-feed occurs.
Using at a high separating pressure from the beginning causes problems such as paper jam at the separator and
abnormal wear of the paper feed ring.
