In addition to the descriptions below and those given in this manual, there are many situations and circumstances that are dangerous.
Page 7: Laser Beam
Laser Beam ROS ASSY This printer incorporates the laser radiation unit (ROS ASSY) of Class IIIb as specified in IEC60825-1. Warning Label Maximum average electric power: 10 mW Wavelength: 770 ~ 790 nm To prevent the laser radiation unit from emitting the laser beam unexpectedly, this printer is equipped with a switch (INTERLOCK S/W 5V) which physically cuts off the power to the laser beam output circuit.
Page 8 High Temperature Assembly Ozone To prevent you from becoming injured or burned, do the following: Before working Because of the printing principle of laser printers, this machine emits a very small with a high temperature assembly (e.g., FUSER ASSY), be sure to turn off the power, amount of ozone in the process of printing.
Page 9 Warning/Caution Labels Parts Warning labels and caution labels are affixed to this printer for accident prevention. To prevent you from becoming injured, keep the following in mind: Take due care in handling the printer, which is very heavy (main unit: 19.5 kg). In maintenance work, check that the labels are free from peeling C H E C K P O I N T...

Development using the video signal transmitted from the Main Board Assy to the MCU of the for the next print HVPS/MCU.
Page 35 EPSON EPL-N3000/AcuLaser M4000N Revision C The laser beam striking the Drum surface excites the electrons moving toward the conductor and consequently generates “electron ⇔ hole” pairs inside the photoconductive layer. Electrons, attracted by the electric field, move toward the inner FUSER ASSY metal portion of the drum and flow in there.
Page 36 EPSON EPL-N3000/AcuLaser M4000N Revision C In the cleaning process, the surface of the Drum is cleared of the remaining toner to get ready for the next cycle. The toner is scraped off with the cleaning blade from the surface of the Drum.
Page 37: Print Data Flow
EPSON EPL-N3000/AcuLaser M4000N Revision C 2.2 Print Data Flow The print data (electrical signal) from the printer controller forms the print image via the processes as shown in the flowchart below.
