Page 266: Paper Feed Cassettes
Paper feed cassettes IPS 12 / 22 IPS 11 / 21 IPS 10 / 20 IPS 10, 11, and 12 = Upper level paper size detector sensors IPS 20, 21, and 22 = Lower level paper size detector sensors There are three holes in the forward end of the cut–sheet paper feed cassettes. Plastic inserts are to be set in these holes according to the size of the cut–sheet paper loaded in the cassette (as shown in the table below).
Page 267: Upper Level / Lower Level Paper Empty Sensor (Pes1 / Pes2
Upper level / lower level paper empty sensor (PES1 / PES2) These sensors are photo–interrupters. When the paper in the paper supply cassette runs out, the lever lowers and blocks the light between the light emitters and receptors, causing detection of no paper. Cut sheet feed sensor (PFS), paper register sensor These sensors are photo–interrupters located partway in the paper transport path.
Page 268: Paper Timing Sensor (Pts
Paper timing sensor (PTS) This sensor is also a photo–interrupter. However, because the output signal is used as the cut–sheet leading–edge detection signal and affects printing quality, the mechanical aspects (lever) have been eliminated. The paper timing sensor consists of an LED light emitter and receptor on either side of the transport path.
Page 269: Cut Sheet Pick Up Motor Encoder (Pme
Cut sheet pickup motor encoder (PME) This is a rotary encoder, comprised of a slotted plate attached to the cut–sheet pick up motor rotating axis, with a light emitter and receptor on either side of the plate. The motor rotation is detected by the pulse string that is created by light passing through the rotating slotted plate.
Page 270: Cut Sheet Feed Motor Encoder (Fme

Page 300: Control Principles
Control Principles The following control detectors (sensors and switches) are built into the power stacker. Transfer Unit Paper Sensor (PMS) This is a photo–interrupter comprised of a light emitter and receptor and a lever. It is located partway in the paper guide at the entrance of the power stacker. When paper output from the printer passes through the guide and kicks the lever, the light passing between the light emitter and receptor is blocked, causing paper to be detected in that location.
Page 301: Jam Sensor (Pps
Jam sensor (PPS) This also is a photo–interrupter comprised of a light emitter and receptor and a lever. It is located partway on the toothed belt. When the paper fold falls on this belt and kicks the lever, the light passing between the light emitter and receptor is blocked, and the sensor turns on.
Page 302: Paper Surface Sensor 1/2 (Pss1/2
Paper surface sensor 1/2 (PSS1/2) These sensors are each comprised only of light emitters and receptors located on the front side and rear side. When paper stacking up on the elevator table reaches this height, the light is blocked, and turns the sensor on. This sensor controls the height of the elevator table.
Page 303: Stacker Full Sensor (Sfs), Elevator Down Sensor (Eds
Stacker full sensor (SFS), Elevator down sensor (EDS) These are also photo–interrupter sensors, both used for detecting the position of the elevator table. The stacker full sensor indicates that the amount of folded paper has reached the limit. The elevator down sensor indicates that the elevator which has begun its way down has reached the down position (the position where the operator removes the paper).

Page 305: Stacker Motor Encoder (Sme), Elevator Motor Encoder (Eme
Stacker motor encoder (SME), Elevator motor encoder (EME) These sensors detect abnormal DC motor revolution. They consist of a mask attached to the motor axis, light emitters, and light receptors. The motor revolution is monitored by the length of time that blockages of light occur between the light emitter and receptor.
Page 306: Swinger Position Sensor (Sps), Assisting Arm Position Sensor (Aps1
Swinger position sensor (SPS), Assisting arm position sensor (APS1) These sensors detect the home position of the stepping motor. They consist of a slotted plate, light emitters, and light receptors. The location of the slot detected by the light emitters and receptors is set as home position. Motor revolution abnormality is also monitored by whether home position is detected within the set time.
Page 307: Elevator Upper Limit / Lower Limit Switches (Limt1 / Limt2
Elevator Upper limit / Lower limit switches (LIMT1 / LIMT2) These are limit switches to prevent the elevator table from rising too high or dropping too low. If for some reason the elevator table rises abnormally high or drops abnormally low, one of these switches comes on, and the elevator table stops. Elevator upper limit switch Elevator lower...
Page 308: Safety Sensors 1/2 (Ss1/2
Safety sensors 1/2 (SS1/2) These are safety switches in case the operator accidentally gets his hand caught between the frame and elevator table of the power stacker. When this happens, the bar inside the cover tilts, and the contact point opens. This switch is interlocked with the power stacker 24V system (actuator drive system).
Page 309: Detection Errors
Detection Errors The errors detected by these sensors and switches are as follows: Operator call status error Error Code Contents Interlock action Safety sensor 1 or 2 turned off, and interlock operated. Folding defective Defective folding of paper occurred (PPS on or off time counted up).
Page 310: Basic Operation
Basic Operation After initializing (due to turning on the power or receiving an initialization request from the printer), the power stacker enters into the following main loop and repeatedly executes the various subroutines. However, the actuator driving subroutines are selectively executed only upon the power stacker receiving execution commands from the printer.
Page 311 Status confirmation processing Checks the detection data of the sensors and switches within the paper feeding unit. If there is any abnormality, executes abnormality processing. Communication processing Loads data transmitted from the printer, executes command analyzing processing, and returns status. Driving the stacker Initializes, drives, and stops the stacker.
