If the above control does not finish within 2.5 seconds when the fixing unit is installed, "pressure release mechanism abnormality" is notified to the video

controller.

- No fixing unit

If the fixing pressure release sensor does not turn ON during the above control when the fixing unit is not installed, "fixing unit absence" is notified to the video

controller.

If the "pressure release mechanism abnormality" or the "fixing unit absence" is detected, it is notified to the video controller.

2.5.3 Detecting Jams

2.5.3.1 Jam Detection Outline

2.5.3.1.1 Outline

/ i-SENSYS LBP5360 / i-SENSYS LBP5300

This printer is provided with several paper detection sensors on the paper transport path to detect the presence of paper and whether the paper feed is operated

normally or not.

If the DC controller determines the jam occurrence, it stops the printing operation and notifies it to the video controller of jam occurrence.

2.5.3.2 Delay Jams

2.5.3.2.1 Pick-up delay jam

/ i-SENSYS LBP5360 / i-SENSYS LBP5300

This printer performs the retry control, which executes the pick-up operation up to three times, in order to retrieve the pick-up delay jam caused by the pick-up error.

The DC controller determines the pick-up delay jam, when the top of page sensor (SR710) does not detect the leading edge of paper within the specified period of

time (T) after the pick-up solenoid (SL5012, SL5013) is turned ON for the third pick-up operation.

2.5.3.2.2 Delivery delay jam

/ i-SENSYS LBP5360 / i-SENSYS LBP5300

The DC controller determines the delivery delay jam, when the fixing paper sensor (SR6005) does not detect the leading edge of paper within the Approx. 3.0

seconds after the top of page sensor (SR710) once detected the leading edge of paper.
