Page 15 Page: 3 Service Manual for OF5300/5600 Chapter 0 Introduction May, 1998 RE: OKIFAX 5050 Service Authorization Dear Okidata Facsimile Dealer: Okidata is proud to announce the addition of the OKIFAX 5050 to our facsimile product line. Enclosed is the OKIFAX 5050 Service Information Addendum, which will assist you in your efforts to support this product.
Page 16 Page: 4 Service Manual for OF5300/5600 Chapter 0 Introduction Functionality The OKIFAX 5050 is technically similar to the OKIFAX 5300. The physical appearance is identical to the OKIFAX 5300; however, the OKIFAX 5050 is strictly a stand-alone facsimile product. Although there is a PC Interface connection socket on the OKIFAX 5050's Main Control Board, this socket is not functional, and the PC Interface cannot be used on this product.

All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material.
Page 424 Page: 264 Service Manual for OF5300/5600 Chapter B Print Operation Description Hopping and feeding are affected by a single resist motor in the mechanism shown below. Turning the resist motor in the "a" direction drives the hopping roller. Turning the resist motor in the "b" direction drives the resist roller.
Page 425 (b) Feeding 1 After end of hopping, turning the resist motor in the "b" direction (in the counter-clockwise [CCW] direction) drives the resist 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 clutch gear.) 2 The paper is further advanced in synchrony with the print data.
Page 426 Page: 265 Service Manual for OF5300/5600 Chapter B Print Operation Description Charging is affected by applying a DC voltage to the charge roller that is in contact with the image drum surface. The charge roller is composed of two layers consisting of a conductive layer and a surface protective layer that has elasticity, in order to secure a good contact with the image drum.
Page 427 Page: 266 Service Manual for OF5300/5600 Chapter B Print Operation Description 3) Exposure Light emitted from the LED head irradiates the image drum surface with negative charges. The surface potential of the irradiated part of the image drum drops, thereby forming an electrostatic latent image associated with the image signal.
Page 429 Page: 267 Service Manual for OF5300/5600 Chapter B Print Operation Description Toner is attracted to the electrostatic latent image on the image drum surface to convert it into a visible toner image. Developing takes place at 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.
Page 431 Page: 268 Service Manual for OF5300/5600 Chapter B Print Operation Description The transfer roller is composed of conductive sponge material and is designed to make the image drum surface and the paper closely into contact. Paper is placed over the image drum surface, and a positive charge, opposite in polarity to the toner, is applied to the paper from its reverse side.
Page 432 Page: 269 Service Manual for OF5300/5600 Chapter B Print Operation Description After the end of the transfer operation, the unfused toner image is fused on the paper under heat and pressure as it passes between the heater roller and the back-up roller. The heater roller with a Teflon coating incorporates a 500 W heater (Halogen lamp), which heats the heat roller.
Page 433 Page: 270 Service Manual for OF5300/5600 Chapter B Print Operation Description After the end of the transfer, residual toner on the image drum is attracted to the cleaning roller temporarily by static electricity to clean the image drum surface.

Page 490 Page: 311 Service Manual for OF5300/5600 Chapter F Second Paper Feeder When the Second Paper Feeder is installed, 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 493 Page: 314 Service Manual for OF5300/5600 Chapter F Second Paper Feeder The Second Paper Feeder feeds the paper into the facsimile by receiving the signal from the facsimile, which drives the pulse motor inside the Second Paper Feeder, and this motion is transmitted to rotate the one-way clutch of the hopping frame assembly.
Page 494 Page: 315 Service Manual for OF5300/5600 Chapter F Second Paper Feeder 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.
