Wrap Jam

The delivery sensor goes on, but it goes off before a specific period of time passes.

Delivery Stationary Jam

The delivery sensor goes on, but it does not go off within a specific period of time.

Initial Jam

The top sensor or the delivery sensor goes on while the main motor is starting to rotate.

Cover Open Jam

The machine identifies a condition in which the front cover is opened while it is moving paper.

2.4.2.2 Delay Jams

2.4.2.2.1 Pickup Delay Jam

/ / FAX-L390 / / / FAX-L380S

If the top sensor does not detect the leading edge of paper within 1.2 sec after the start of pickup operation, the machine initiates pickup operation once gain. The

machine identifies a pickup delay jam if the top sensor does not detect the leading edge of paper within 1.2 sec after the 2nd pickup operation.

2.4.2.2.2 Delivery Delay Jam

/ / FAX-L390 / / / FAX-L380S

The machine identifies a delay jam if the delivery sensor does not detect the leading edge of paper within 1.615 sec after the top sensor has detected the leading

edge of paper.

2.4.2.3 Stationary Jams

2.4.2.3.1 Pickup Stationary Jam

/ / FAX-L390 / / / FAX-L380S

The machine identifies a pickup stationary jam if the top sensor does not detect the absence of paper within 3.575 sec after the top sensor has detected the leading

edge of paper.

2.4.2.3.2 Delivery Stationary Jam

/ / FAX-L390 / / / FAX-L380S

The machine moves to a delivery stationary jam sequence if it does not detect a wrap jam.

The machine identifies a delivery stationary jam if the delivery sensor does not detect the trailing edge of paper for 1.715 sec after the top sensor has detected the

trailing edge of paper.

2.4.2.4 Other Jams

2.4.2.4.1 Wrap Jam

/ / FAX-L390 / / / FAX-L380S

The machine starts a wrap jam detection sequence in 0.1 sec if it does not detect a delivery delay jam.

It identifies a wrap jam if the delivery sensor detects the trailing edge of paper within 1.06 sec after the top sensor has detected the trailing edge of paper.

The term "wrap jam" refers to paper that wraps around the fixing pressure roller; its leading edge passes through the delivery sensor, but it jams thereafter. The

machine is designed to identify such a jam so as to prevent wrapping paper from fully moving into the fixing assembly.

2.4.2.4.2 Initial Jam

/ / FAX-L390 / / / FAX-L380S

The machine identifies an initial jam if the top sensor or the delivery sensor detects the presence of paper when the main motor starts to rotate.

2.4.2.4.3 Cover Open Jam

/ / FAX-L390 / / / FAX-L380S

The machine identifies a cover open jam if it detects that the front cover is open with the top sensor or the delivery sensor detecting the presence of paper (while

paper is being moved or the machine is not running a jam check).
