Page 84 EPSON AcuLaser CX11/CX11F Revision B 2.2.1.3 Technical Explanation of Print Process CHARGING At the "Charging" process, BCR (Bias Charge Roll) applies a uniform negative potential to the drum which rotates at a fixed speed. BCR keeps contact with the drum and moves together with it.
Page 85 EPSON AcuLaser CX11/CX11F Revision B EXPOSURE At the "Exposure" process, a laser beam is applied to the negatively charged surface of the drum to form an invisible electrostatic latent image onto the drum. The laser beam is emitted from a laser diode in the ROS ASSY, and directed by the polygon mirror, fixed mirror and lens of the Scanner Assy in the ROS ASSY.
Page 86 EPSON AcuLaser CX11/CX11F Revision B DEVELOPING At the "Developing" process, toner is electrically applied to the invisible electrostatic latent image on the drum, to form a visible image on it. This printer uses two developing systems: a "rotary developing system" that successively rotates four Developer Assys, and a "trickle developing system"...
Page 87 EPSON AcuLaser CX11/CX11F Revision B Toner in the Developer Assy is consumed as the number of prints increases. To The charging characteristics of the carrier is depleted due to dirt caused by the maintain the appropriate development density, the equivalent amount of consumed toner or due to scratches caused by stirring.
Page 88 EPSON AcuLaser CX11/CX11F Revision B PRIMARY TRANSFER (DRUM→BELT) At the “Primary transfer” process, the toner image formed on the drum surface is transferred to the Belt surface in Photoconductor Unit by 1st BTR (First Bias Transfer Roll). The 1st BTR is a conductive roller, and is positively charged by the HVPS. The 1st BTR contacts the back side of the Belt and charge the back side to positive.
Page 89 EPSON AcuLaser CX11/CX11F Revision B CLEANING (DRUM) At the "Cleaning (drum)" process, residual toner is removed from the drum surface. Cleaning the drum Toner that was not transferred to the Belt at the "Primary transfer" process remains on the drum surface. Since the remaining toner hinder subsequent processes, it is scraped off by a Cleaning Blade that contacts with the drum, and is collected in the Waste Toner Box.
Page 90 EPSON AcuLaser CX11/CX11F Revision B REPEAT (FORMATION OF COMPLETE TONER IMAGE) At the "Repeat (formation of complete toner image)" process, the toner images of each color formed on the drum surface are successively transferred to the Belt to form a complete toner image composed of the four colors on the Belt surface.
Page 91 EPSON AcuLaser CX11/CX11F Revision B SECONDARY TRANSFER (BELT→PAPER) At the "Secondary transfer" process, the complete toner image formed on the Belt surface is transferred to paper by the 2nd BTR (Second Bias Transfer Roll). The 2nd BTR comes in contact with the Belt only when transferring the image to paper to prevent the toner image formed on the Belt surface from being destroyed.
Page 92 EPSON AcuLaser CX11/CX11F Revision B DISCHARGING FUSING At the "Discharging" process, the charge on the paper is neutralized/removed by the At the "Fusing" process, toner is fixed on paper with heat and pressure. Detack Saw. Fuser Assy does not have a pressure roll, but has a Fuser Belt instead.
