    2.1 Printer Mechanism Operating Principles The following diagram shows the major parts, including the sensors, and the paper paths in the printer. The printer consists of the paper feed section, print head unit (exposure section), imaging cartridge (charging section and development section), transfer section, fusing section, and paper exit section Figure 2-1.

  • Page 52: General Description Of Each Section

    Paper Exit Section The paper which has passed the fusing section is ejected to the top of the printer with the paper exit roller. The paper exit sensor (PC3) senses the ejection of the paper. When the optional duplex unit are installed: For duplex printing, the trailing edge of the printed paper is drawn inside the duplex unit by the switch back motor in the duplex unit.

  • Page 57 If the MP cassette is not installed in the MP Tray: The projection of the paper cassette comes off the sensor which is mounted on the printer. In this case, the light emitted from the LED of the photointerrupter reaches the phototransistor of the photointerrupter and the phototransistor turns ON.
  • Page 58 Operating Principles Timing Roller Front Sensor (PC2) This sensor detects that the paper is fed inside the printer. The sensor uses a photointerrupter. The output of the sensor is used as a reference for feeding paper inside the printer. This sensor will be activated when paper is fed from any paper source.
  • Page 59 The paper size detection mechanism consists of the arm that joins with the rear paper guide and four mechanical switches in the printer body. When the rear paper guide is aligned with the paper size, the arm swivel accordingly, as shown below. The arm has a notch, which moves as the arm swivels to turn on/off the four mechanical switches.

    EPL-N2700 2.2.1.2 Electrical Section The power supply system and the signal lines are shown below. The power supply unit supplies DC +5 V and DC +24 V to the main control board. It also supply an AC voltage to the heater lamp. The main controller (video controller) receives a compressed print data from the host PC through an interface.

  • Page 78: Main Circuit (Video Controller)

    Data sent from the host PC is input to the main circuit via an interface or network board. The C269MAIN, the main circuit of the printer, converts data from the PC into raster data to generate video signals. The video signals turn on/off the laser diode on the printhead to form latent images on the PC drum.
