Page 28 Page: 13 Service Guide OKIPAGE16n Chapter 2 Operation Description 2.4.1 Electrophotographic process mechanism This mechanism prints image data from the control board on the paper by electrophotographic process. The Figure 2-4 shows the layout of the electrophotographic process mechanism. (1) Image drum unit The image drum unit consists of a sensitive drum, a charger, and a developer.
Page 29 If the heater roller temperature rises abnormally, the thermostat of the heater voltage supply circuit is activated to cut the AC voltage supply immediately.

Page 30: Electrophotographic Process
Page: 14 Service Guide OKIPAGE16n Chapter 2 Operation Description 2.4.2 Electrophotographic process The electrophotographic processing is outlined below. Figure 2-5 shows the electrophotographic printing process. 1 Charging The surface of the image drum is uniformly charged with negative charges by applying a negative voltage to the charge roller.
Page 32: Process Operation Descriptions
Page: 15 Service Guide OKIPAGE16n Chapter 2 Operation Description 2.4.3 Process operation descriptions (1) Hopping Feeding from the first tray and the front feeder are effected by a single hopping motor in the mechanism shown below. Turning the Hopping motor in the "a" direction drives the hopping roller of the first tray. Turning the Hopping motor in the "b"...
Page 33 (a) Hopping (1st tray) Rotating the pulse motor in the direction a (clockwise [CW] direction) drives the hopping roller of the first tray to advance the paper until the inlet sensor turns on. At the same time, the one-way clutch gear B also rotates. However, the hopping roller of the front feeder will not rotate due to the one-way bearing.
Page 34 (b) Hopping (front feeder) Rotating the pulse motor in the direction b (counterclockwise [CCW] direction) drives the hopping roller of the front feeder to advance the paper until the inlet sensor turns on. At the same time, the one-way clutch gear A also rotates. However, the hopping roller of the 1st tray will not rotate due to the one-way bearing.
Page 35 After turning on the inlet sensor, the paper advances further by a predetermined length until it hits the registration roller. (The skew of the paper can thus be corrected.)
Page 36 (2) Feeding After the end of hopping, the pulse motor dedicated for driving the registration roller rotates to drive the registration roller. The driven registration roller advances the paper until it comes out of the registration roller. When the leading edge of the paper causes the paper sensor to turn on, the printing is started synchronously.
Page 37 (4) 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. (5) Developing Toner is attracted to the electrostatic latent image on the image drum surface to convert it into a visible toner image.
Page 38 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. Toner is attracted to the exposed part (low-potential part) of the image drum at the contact between the image drum and the developing roller, making the electrostatic latent image visible.
Page 39 (7) Fusing After the end of the transfer, the unfused toner image is fused on the paper under heat and pressure as it passes between the heater roller and the backup roller. The heater roller with a Teflon coating incorporates a 400W heater (Halogen lamp), which heats the heat roller. A thermistor which is in contact with the heater roller regulates the heater roller at a predetermined temperature (about 185 ~ 188°C).
Page 40 (8) Cleaning 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. (9) Cleaning of rollers The charge roller, transfer roller and cleaning roller are cleaned in the following cases: In warming up at power-on time In warming up after the cover is opened and closed...

Page 44: Toner Low Detection
Page: 18 Service Guide OKIPAGE16n Chapter 2 Operation Description 2.7 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 45 Operation during toner low state When the stirring bar reaches the maximum height, since there is no resistance provided by the toner on the other side, it falls to the minimum height due to its own weight. Because of this, the time interval during which it encounters the magnet of the sensor lever becomes long. By monitoring this time interval, toner low can be detected.
Page 46 Toner Sensor Alarm is activated. The toner sensor is not monitored while the drum motor is stopped. Copyright 1997, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
