The stirring bar rotation is driven by the link to the gouged portion in the stirring gear.
Page 846 Operation during Toner Low state When the stirring bar reaches the maximum height, it falls to the minimum height due to its own weight, since there is no resistance provided by the toner on the other side. Because of this, the time interval during which it is in encounter with the magnet of the sensor plate becomes longer.

Page 856: A3.1.13 Process Operation Descriptions
Service Guide OKIFAX 5750/5950 Page: 285 Chapter A Board Descriptions A3.1.13 Process Operation Descriptions (1) Hopping and Feeding Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below: The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b" drives the registration roller. The registration and hopping gears have one-way bearing, so turning any of these gears in the reverse direction will not transmit the motion to the corresponding roller.
Page 857 (2) After inlet sensor is turned on by the paper advance, the paper is further advanced to a predetermined distance until the paper hits the registration roller (the skew of the paper can thus be corrected.) (b) Feeding (1) When hopping is completed, the registration motor turning in direction "b" (counter-clockwise direction) drives the registration roller to advance the paper (in this case, the hopping gear also turns, but the hopping roller is prevented from turning by the one-way bearing.) (2) The paper is further advanced in synchronization with the print data.
Page 858 (2) Charging Charging is actuated by application of the DC voltage to the charge roller that is in contact with the image drum surface.
Page 859 The charge roller is composed of two layers, a conductive layer and a surface protective layer, both having elasticity to secure good contact with the image drum. When the DC voltage applied by the power supply exceeds the threshold value, charging begins.
Page 860 Light emitted by the LED head irradiates the image drum surface with a negative charge. The surface potential of the irradiated portion of the image drum drops, forming an electrostatic latent image associated with the image signal. The image drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer layer (CTL) on aluminum base. The organic photo conductor layer (OPC), comprising a CTL and a CGL, is about 20 m m thick.
Page 862 (4) Developing Toner is attracted to the electrostatic latent image on the image drum surface, converting it into a visible toner image. Developing takes place through the contact between the image drum and the developing roller. (1) As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated between the developing roller and the toner, allowing the toner to be attracted to the developing roller (the developing roller surface is charged positive and the toner, negative.)
Page 863 (2) The toner attracted to the developing roller is scraped off by the doctor blade, forming a thin coat of toner on the developing roller surface. (3) Toner is attracted to the exposed portion (low-potential part) of the image drum at the contact of the image drum and the developing roller, making the electro-static latent image visible.
Page 864 An illustration of activities at the contact point of the image drum surface and the developing roller (arrow marks denote the direction of the electrical field). Note: The bias voltage required during the developing process is supplied to the toner supply roller and the developing roller, as shown below. -500 VDC is supplied to the toner supply roller, -265 VDC to the developing roller.
Page 865 The application of a high positive voltage the from the power supply to the transfer roller causes the positive charge inducement on the transfer roller surface, transferring the charge to the paper as it contacts the transfer roller. The toner with negative charge is attracted to the image drum surface, and it is transferred to the upper side of the paper due to the positive charge on the reverse side of the paper.
Page 866 (7) Cleaning of rollers When the transfer is completed, the residual toner left on the image drum is attracted to the cleaning roller temporarily by static electricity, and the image drum surface is cleaned.
Page 867 Changes in bias voltage applied to each roller move attaching toner off the roller to the image drum and return it to the developer. Copyright 2000, Oki Data, Division of OKI America, Inc. All rights reserved. See the Oki Data Business Partner Exchange...

Page 946: B.3.3.1 Toner Low Detection
Service Guide OKIFAX 5750/5950 Page: 305 Chapter B Print Operation Description B.3.3.1 Toner Low Detection Composition The device consists of the stirring gear which rotates at a constant rate, the stirring bar and the magnet on the stirring bar. The stirring bar rotates through the link on the protrusion in the stirring gear.
Page 947 Operation during Toner Low state When the stirring bar reaches the maximum height, it falls to the minimum height due to its own weight, since there is no resistance provided by the toner on the other side. Because of this, the time interval during which it is in encounter with the magnet of the sensor plate becomes longer.
Page 948 When there is no change with the toner sensor for 2 cycles (2.63 sec. x 2) or more, then the Toner Sensor Alarm is activated. Copyright 2000, Oki Data, Division of OKI America, Inc. All rights reserved. See the Oki Data Business Partner Exchange...

Page 980: Functions
1.1 Functions When the Second Paper Feeder is installed with the OKIFAX 5750/5950 series facsimile transceiver, the Second Paper Feeder is connected to the facsimile by a connector. The Second Paper Feeder supplies paper automatically through the operation of pulse motor (hopping), which is driven by signals sent from CPU of the Second Paper Feeder under the control of the facsimile.

Page 984: Hopper Mechanism
The hopper automatically feeds the facsimile with the paper being set, single sheet at a time. When the paper is loaded in the paper cassette, it is then transported by the pulse motor, carrying forward only a single sheet caught by the separation rubber at a time.
