    November 29, 1999 ADF/SCANNER 2. DETAILED SECTION DESCRIPTIONS 2.1 ADF/SCANNER 2.1.1 OVERVIEW H306D516.WMF 1. Document detection • The machine detects when a document is placed in the ADF by monitoring the document sensor (S1). • From the combined output of the document (S1), B4 width, and A3 width sensors, the ADF can detect three possible widths: A4, B4, and A3.

  • Page 26: Detailed Descriptions

    ADF/SCANNER November 29, 1999 2.1.2 DETAILED DESCRIPTIONS Document Detection H306D001.WMF H306D002.WMF When a document is inserted, the document sensor (S1 sensor) [A] turns on and detects the document. The width of the document is then detected from the combined output of the S1, B4 width [B], and A3 width [C] sensors. If a document is set on the MDF table, the MDF sensor [D] turns on and detects it.
  • Page 27 November 29, 1999 ADF/SCANNER Document Pick-up H306D003.WMF H306D004.WMF When the scanner motor [F] starts rotating clockwise, the pick-up roller [A] lowers to feed the top sheet of the document. The paper is then separated by the reverse roller [D] and fed to the R0 [E] roller. Since the R0 roller rotates faster than the feed roller [B], the pick-up roller and feed roller add to the load on the scanner motor while the R0 roller feeds the document.
  • Page 28 ADF/SCANNER November 29, 1999 Document Feed H306D006.WMF H306D516.WMF The scanner motor [A] drives the R0 [B], R1 [C], R2 [D] and the document exit rollers [F], all responsible for feeding the document. The scan line lies between the R1 and R2 rollers. The scan line sensor (S2) [E] is between the R1 and R2 rollers, and detects when the leading and trailing edges of the document are at the scan line.
  • Page 29 November 29, 1999 ADF/SCANNER Returning to Ready Status H306D005.WMF When the last page of the document has been fed out, the scanner motor turns clockwise, then counterclockwise, and clockwise again. This lifts the pick-up roller to its ready position. This is also done at the following times: •...
  • Page 30 ADF/SCANNER November 29, 1999 Image Scanning H306D019.WMF H306D007.WMF When the document sent by the R1 roller [B] passes over the exposure glass, it is exposed to light from the xenon lamp [A] inside the optical unit [C]. The light reflected from the document is then focused onto the CCD on the SBU. When the start key is pressed, the xenon lamp activation signal turns the lamp on.
  • Page 31 November 29, 1999 ADF/SCANNER Jam Detection 1. Non-feed (error code 1-00): The S2 sensor does not activate even after the machine tries to feed the document to the scan line three times. 2. MDF Non-feed (no error code): The S2 sensor does not activate after manual document feed to the scan line. 3.

  • Page 33: Laser Exposure

    November 29, 1999 PRINTER 2.2.2 LASER EXPOSURE Overview This machine uses a laser diode to produce electrostatic images on an OPC drum. The laser diode unit converts image data from the FCU into laser pulses, and the optical components direct these pulses to the drum. Exposure of the drum by the laser beam creates the latent image.
  • Page 34 PRINTER November 29, 1999 Optical Path H306D008.WMF The LD unit [A] outputs the laser beam to the polygonal mirror [B] through the cylindrical lens [C], which focuses the laser beam. The laser beam goes to the F-theta mirror [D], 1st mirror [E] and BTL [F]. Then, the beam reaches the drum [G] through the shield glass [H].

  • Page 39 November 29, 1999 PRINTER Drum Charge H306D511.WMF This machine uses a drum charge roller system instead of a scorotron corona wire system to charge the drum. The drum charge roller [A] always contacts the surface of the drum [E] because of the charge roller pressure springs [C], and gives a negative charge to the drum surface.
  • Page 40 PRINTER November 29, 1999 Development Overview H306D509.WMF This machine uses mono-component toner. The AIO cartridge contains two agitators [F]. The agitator(s) [F] and the mixing blade [D] mix the toner in the toner cartridge and transport it to the development roller [C]. Friction between the transported toner and the doctor blade [A] gives the toner a negative charge.
  • Page 41 November 29, 1999 PRINTER Toner Near-End Sensor The toner near-end sensor monitors the toner concentration by checking the magnetic field strength. When the reading goes down to a threshold value, the machine enters the near- end condition. The threshold value cannot be changed. A hundred pages can be printed after detecting the near-end condition, and then the machine stops printing and toner end is detected.
  • Page 42 PRINTER November 29, 1999 Drum Cleaning H306D512.WMF The cleaning blade [A] removes any toner remaining on the drum after the image is transferred to the paper. The toner remaining on the drum is scraped off by the cleaning blade and transferred to the collection area. The mylar sheet [B] prevents the toner from dropping out of the cleaning unit.

  • Page 43: Transfer And Paper Separation

    November 29, 1999 PRINTER 2.2.4 TRANSFER AND PAPER SEPARATION Overview H306D513.WMF The machine uses a transfer roller [A] which touches the surface of the drum [B]. The high voltage supply unit supplies a positive current to the transfer roller. A feedback circuit inside the machine automatically keeps the transfer current constant.
  • Page 44 PRINTER November 29, 1999 Transfer Roller Cleaning If the paper size is smaller than the printed image, or if a paper jam occurs during printing, toner may be transferred to the roller surface. To prevent this toner from transferring to the back side of the printouts, the transfer roller has to be cleaned before the next printing run.

    PRINTER November 29, 1999 Paper Near-end Detection When the paper supply in the tray becomes low, the bottom plate [A] pushes up on the actuator of the paper near end sensor [B] and the near end condition is detected. This occurs when approximately 50 sheets are remaining in the tray.
  • Page 49 November 29, 1999 PRINTER By-pass Tray (Printer I/F Unit Required) When the registration sensor [A] turns on after paper is set on the by-pass tray [B], the paper is fed and held by the registration roller to ensure that it does not fall from the tray.

    PRINTER November 29, 1999 2.2.6 FUSING Overview H306D017.WMF The fusing unit consists of the following parts. 1. Pressure Roller Release Lever 6. Exit Roller 2. Pressure Spring 7. Hot Roller Stripper 3. Fusing Lamp 8. Pressure Roller 4. Fusing Thermistor 5.
  • Page 51 November 29, 1999 PRINTER Fusing Process H306D013.WMF After the image has been transferred, the paper enters the fusing unit. The image is fused to the paper by applying heat and pressure through the combination of the hot roller [A], the fusing lamp [B], and the pressure roller. The CPU monitors the hot roller temperature through the fusing thermistor [C] that is in contact with the hot roller surface.
  • Page 52 PRINTER November 29, 1999 Pressure Roller/Paper Exit H306D014.WMF During printing, the pressure roller [A] is pressed against the hot roller [B] by springs. The hot roller strippers [C] separate the paper from the hot roller and direct it to the exit roller.

  • Page 54 PRINTER November 29, 1999 H306D528.WMF The fusing temperature is monitored using the thermistor [A], and the thermofuse [B] is a back-up safety measure. The CPU checks the output from the fusing thermistor once every 20 ms. The CPU compares the current, previous and target temperatures, then decides the power- on ratio for the next 20 ms.
  • Page 55 November 29, 1999 PRINTER Cooling Fan Control The cooling fan has 2 speeds. The speed that is used depends on the fusing unit temperature. High Speed Mode: More than 160 ºC Low Speed Mode: Between 120 ºC and 160 ºC Stop: Below 120 ºC NOTE: The mode will not change until at least 2 seconds has passed since...
