L2000 Technical Training 4d. Paper Pick Up

Sensor Location

Paper Supply

From Multi Purpose Tray  In case of paper pickup from the MP tray, while the main motor rotates, the MP tray pickup  solenoid is turned ON. Then, the MP tray pickup roller rotates, and a sheet of paper is fed into the printer section.  Up to 100 pages (80 g/m 2 ) can be loaded into the MP tray at one time and the position of the movable paper guides can be adjusted for recording paper.

From the Cassette  In case of paper pickup from the cassette, while the main motor rotates, the pickup solenoid is turned ON.  Then, cassette pickup roller, feed roller rotate, and a sheet of paper is fed into the printer section.

From Duplex Unit  Face-up tray is closed, the paper eject sensor detects the trailing edge of the recording paper the reverse motor, sends the paper to the duplex feed unit.  When the paper reaches the reverse paper sensor the duplex solenoid ON to rotate the oblique roller. The paper is then sent to the registration roller. During this operation, if next paper is picked up, the duplex-fed recording paper stops at the specified position.  Then the following paper reaches the page top sensor, the specified period of time passes, and the duplex-fed paper is transported again.  The re-transported paper is printed with the other side and delivered to the output tray.

Paper Jams  Recording Paper Pickup Jam Detection Configuration  Pick-up delay jam  Pick-up stationary jam  a. When WAIT period starts  b. During paper feeding  Delivery delay jam  Delivery stationary jam  a. When WAIT period starts  b. During paper feeding  c. When a pick-up delay jam occurred  d. During pressure roller cleaning  Reversing delay jam  Reversing stationary jam  Duplex pickup delay jam  Duplex pickup stationary jam
