Chapter 88-9F-8-108.3.3.2 Stationary Jam at Power-On 0010-8197iR7105 / iR7095 / iR7086A stationary jam at power-on is identified in relation to the presence/absence of paper over a specific sensor about 1 sec after the control panel power switch isturned on.8.4 Cassette Pick-Up Unit8.4.1 Outline 0010-8199iR7105 / iR7095 / iR7086When the deck or the cassette is slid in, the cassette open/closed sensor turns on and, at the same time, the pickup roller starts to move down, causing the light-blocking plate to leave the lifter sensor, driving the cassette lifter motor and, ultimately, moving up the lifter.The lifter keeps moving up until the lifter sensor detects the surface of paper. (In the case of the deck right/left, a limiter is mounted to stop the lifter if it fails tostop moving up.)When the deck or cassette open button is pushed, the drive gear of the lifter becomes free to let the lifter move down on its own weight.T-8-6Right deck Left deck Cassette 3 Cassette 4Cassette open/closed detection Deck right open/closed sensor(PS23)Deck left open/closed sensor(PS33)Cassette 3 open/closed sensor(PS40)Cassette 4 open/closed sensor(PS45)Lifter position detection Lifter sensor (PS21) Lifter sensor (PS31) Lifter sensor (PS38) Lifter sensor (PS43)Paper presence/absence detection Deck right paper sensor (PS22) Deck left paper sensor (PS32) Cassette 3 paper sensor (PS39) Cassette 4 paper sensor(PS44)Paper level detection Deck right paper level middlesensor (PS51)Deck right paper level uppersensor (PS52)Deck lifter paper level middlesensor (PS54)Cassette 2 paper level uppersensor (PS55)Cassette 3 paper level detectionPCB (variable resistor)Cassette 4 paper leveldetection PCB (variableresistor)Lifter upper limiter Deck right limit sensor (PS24) Deck left limit sensor (PS34) --- ---Drive motor Deck right lifter motor (M13) Deck lifter motor (M14) Cassette 3 lifter motor (M16) Cassette 4 lifter motor (M17)Copy Start keyON orPRINT setINTR / PRINTJam checkSensor N Normal Errorregulation timeregulation timeIf paper is detected here, astationary jam is identified.A jam check is started after feeding"regulation time" upon detection of theleading edge of paper.
