SUBJECT

Countermeasure to Pick-up Errors in Bypass Feeding

MODEL

CATEGORY

Other countermeasures

From Jan. 1998

CONTENT

[Countermeasure] During bypass feeding, the lowering operation may stop before the pick-up roller reaches the sheets stacked on bypass. The result is that the sheets cannot be fed. (bypass pick-up error)

[Cause] The bypass pick-up roller has usually been attached to the upper position. * The paper feed roller rotates at the same time as the start of feeding. * The bypass pick-up roller is lowered by the rotation of the bypass paper feed roller. * The lowering operation is stopped by releasing the spring clutch. The lowering operation is performed as stated above.

At almost the same time as the bypass pick-up roller contacts the sheet, the lowering operation is stopped. As a result, the pick-up roller cannot completely contact on the sheet.

[Countermeasure] To make the pick-up roller contact the sheet, the stopper (bypass frame part) is bent to enable a later clearance timing of the spring clutch (contact timing with the spring clutch).
