40931201TH Rev. 4 199 /2. DESCRIPTION OF OPERARTION2.1 Driving MechanismThe high-capacity second/ third paper feeder only a top paper which is set in the cassette by asignal from the printer.(1) Second paper feeder as an example is shown.First of all, the hopping motor rotates in the direction of arrow A. Roller C rotates by way ofidle gear on the same shaft on which the hopping gear is placed. At the same time,theplanetary gear D shifts in the direction of arrow E and a sub roller gear and a sub roller on thesame shaft rotate. Roller C and sub roller make a paper hop. Also, the planetary gear G shiftsin the direction of arrow H and Roller K rotates, and when the length of sheet is legal 13 inchor more, a hopping paper will be impinged to the regist roller within the printer. When thelength of paper is A4 or less, hopping papers will be carried until the defined amount.(2) When the length of paper is A4 or less, the hopping roller rotates in the direction of arrow Bnext. At this time, the planetary gear G shifts in the direction of arrow I to rotate Roller K andimpinge the papers, which are carried to the defined amount, to the regist roller within theprinter. During the hopping roller is rotating, Roller C is racing because it includes one-waybearing. At the same time, planetary gear D shifts in the direction of arrow F and the sub rollergear and another sub roller on the same shaft won't rotate.(3) In the third paper feeder, when the length of paper is legal 13 inch or more, and if the rotatingdirection is arrow A', papers will be carried to the defined amount without being impinged tothe regist roller, and then the rotating direction of the hopping roller will be changed to arrowB'. When the rotating direction of the hopping roller A' arrow direction, the motion is same as(1). When B' arrow direction, the motion will be same as (2) until Roller K' begin to rotate. Theplanetary gear M' will shift in the direction of arrow L by way of the gear O' which begin to rotateat the same time when the roller K' does. And gear N rotates, resulting in rotating the gearJ and roller K on the same shaft, and impingeing papers to the regist roller within the printer.At this time, as the gear O and gear P engaged by the planetary gear G on the same shaft,on which the gear J and roller K are placed, includes an one-way clutch gear, the planetarygear G won't rotate.Impinged papers are, afterwards, fed by the control of printer's inside.
