Page 60 Maintenance Cleaning the printer Replacing the developer In case that the developer unit is to be removed from the printer for shipment or replacing to a new one, it should be handled following the instructions below. Also, a new developer unit, after installing, needs a special treatment that repletes the developer with toner for printing.
Page 61 Maintenance Cleaning the printer Feeding toner into the new developer The new developer unit is shipped from the factory with no toner contained. The developer can be automatically repleted with toner when a toner container is installed onto it and the printer is turned on. However, because the toner reservoir in the developer has a large capacity, it requires a lengthy period of time until a substantial amount of toner has been fed to get the printer ready.

Page 72 Operation overview Electrophotographics system Charging the drum Figure below is a simplified diagram of the electrophotographics components. Charg- ing the drum is done by the main charger wire (in the main charger unit) marked A in the diagram. As the drum (B) rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+) electrical charge dispersed by the main charger wire (A).
Page 73 Operation overview Electrophotographics system Toner The toner is fed from the toner container (TK-90HM/TH-92HM). The toner is com- prised of the following substances as depicted below. Single component MICR toner A—Resin B—Ferrite for MICR C—Silica D—Polisher FS-1714M/FS-3718M...

Page 75 Operation overview Electrophotographics system The laser beam is switched on for a black dot and off for a white (blank) dot according to the print data. Whenever it is illuminated by the laser beam, the electrical resis- tance of the photoconductor is reduced, the potential on the photoconductor is also lowered to 20V, effectively driving the charge through the a-Si layer down to the aluminum base.

Page 78 Operation overview Electrophotographics system Scanning laser The laser beam hits one of six polygonal mirrors. As the mirror revolves (at the revo- lution of 18,700 rpm for model FS-1714M; 27,000 rpm for model FS-3718M), the laser beam reflects off of it and reaches the charged drum surface in a lengthwise manner. A pair of (plastic) lenses provides focusing the horizontally sweeping laser beam onto the drum.

Page 85 Operation overview Electrophotographics system Development The latent image constituted on the drum is developed into a visible image. The de- veloping roller contains a 3-pole ( ) magnet core and an aluminum cylinder rotat- S-N-S ing around the magnet core. Toner attracts to the developing roller since it is pow- dery ink made of black resin bound to iron particles.
Page 86 Operation overview Electrophotographics system Developing roller bias The developing roller is connected to a -weighted, positive power source. Toner on the developing roller is given a positive charge. The positively charged toner is then attracted to the areas of the drum which was exposed to the laser light. The non-exposed areas of the drum repel the positively-charged toner as these areas maintain the positive charge.
Page 87 Operation overview Electrophotographics system Adjusted to prevent grey background Surface potential = 230V Developing roller bias 120V DC+1.8kV AC (f=2.4 kHz) Developing A toner replenishment sensor is provided within the developer. As the toner supply from the toner container dwindles and the toner level lowers in the reservoir, the sensor translates it through its diaphragm, urging the toner motor to feed more toner.
Page 88 Operation overview Electrophotographics system Transfer The image developed by toner on the drum (“ ” below) is transferred onto the paper using the electric charge attraction given by the toner itself and the transfer roller (“ ” below). The transfer roller is negatively biased so that the positively charged toner is attracted onto the paper while it is pinched by the drum and the transfer roller.
Page 89 Operation overview Electrophotographics system Fusing The toner on the paper is permanently fused onto the paper as it passes between the florin-finished heat roller (“ ” below) and the pressure roller (“ ” below) in the fuser unit. The toner is molten and pressed into the paper. The heat roller has a halogen lamp, turning frequently on and off to maintain a preheat temperature at approxi- mately 185°C for model FS-1714M;...
Page 90 Operation overview Electrophotographics system Drum cleaning and erasing static charge The drum needs to be physically cleaned of toner remaining on its surface in the pre- vious rotation. The cleaning blade (A below) is constantly pressed against the drum and scrapes the residual toner on the drum off to the refresher roller (B below). The refresher roller drives the toner to the spiral (fins) roller (C below) at one end of which the waste toner bottle is connected to collect the waste toner.

Page 223 Paper specifications Other paper properties expand, becoming wavy in appearance. When the relative humidity is low and the paper loses moisture, the edges shrink and tighten, and print contrast may suffer. Wavy or tight edges can cause misfeeding and alignment anomalies. The mois-ture content of the paper should be: 4% to 6%.
Page 224 Paper specifications Special Paper Whiteness: The contrast of the printed page depends on the whiteness of the pa-per. Whiter paper provides a sharper, brighter appearance. Quality control: Uneven sheet size, corners that are not square, ragged edges, welded (uncut) sheets, and crushed edges and corners can cause the printer to mal- function in various ways.
