Chapter 22-29F-2-37Home position controlThe pressurized condition is detected by ON/OFF of the fixing pressure release sensor (SR705) and rotational period of the fixing motor (M1).During initial sequence after power is turned ON or door is closed, the pressurized condition is controlled to "pressurized" as its home position.- Abnormal pressure release conditionIf the above control does not finish within 2.5 seconds when the fixing unit is installed, "pressure release mechanism abnormality" is notified to the videocontroller.- No fixing unitIf 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 videocontroller.If the "pressure release mechanism abnormality" or the "fixing unit absence" is detected, it is notified to the video controller.2.5.3 Detecting Jams2.5.3.1 Jam Detection Outline2.5.3.1.1 Outline0013-8288/ i-SENSYS LBP5360 / i-SENSYS LBP5300This 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 operatednormally 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 Jams2.5.3.2.1 Pick-up delay jam0013-8290/ i-SENSYS LBP5360 / i-SENSYS LBP5300This 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 oftime (T) after the pick-up solenoid (SL5012, SL5013) is turned ON for the third pick-up operation.T-2-32.5.3.2.2 Delivery delay jam0013-8294/ i-SENSYS LBP5360 / i-SENSYS LBP5300The DC controller determines the delivery delay jam, when the fixing paper sensor (SR6005) does not detect the leading edge of paper within the Approx. 3.0seconds after the top of page sensor (SR710) once detected the leading edge of paper.2.5.3.2.3 Duplexing pick-up delay jam0013-8299/ i-SENSYS LBP5360 / i-SENSYS LBP5300Paper sourceCassette Multi-purpose tray Paper feederTime (T) Approx. 1.3 sec.
