EPSON EPL-5800 Revision B 2.1 Operating Principles of Mechanism 2.1.2 Paper Feed Mechanism 2.1.1 Paper Path Multi Paper Feed Tray The following figure shows the major paper paths in the printer. EPSON EPL-5800 has two paper feed methods as standard; multi paper feed tray (150 sheets) and manual feed (1 sheet). With the optional second paper feed unit (500 sheets), EPSON EPL-5800 has three paper feed methods.
PAGE 45
EPSON EPL-5800 Revision B Paper Feed Roller Paper Feed Sensor (PS1) Push Down Cam When there is paper on the tray, the actuator stands up and the sensor is turned OFF. When paper on the tray went out, the actuator falls into the hole of the tray and the sensor is turned ON. 2.1.2.
PAGE 46
EPSON EPL-5800 Revision B PAPER EMPTY SENSOR Table 2-1. ON/OFF of SW21 on each cassette type Paper empty sensor (PI21) is mounted on the relay board (PWB-A) of the second paper feed unit and it detects paper empty in the second paper feed cassette. When there is paper on the tray, the actuator stands up and the sensor becomes OFF. When paper on the tray went out, the actuator falls into the hole of the tray lifting board and the sensor becomes ON.

EPSON EPL-5800 Revision B 2.1.3 Charging Process Drum Cartridge 2.1.3.1 Overview ! It is charged by giving static electricity to OPC drum (Organic Photoconductor) before laser exposure. Rotation Brush (Charging Brush) ! Surface of OPC drum is charged by rotating brush (charging brush) and precharging film.
PAGE 48
EPSON EPL-5800 Revision B 2.1.4 Exposure Process The laser beam from the print head creates an electrostatic latent image on the OPC drum surface. The following control is performed in order to find appropriate timing to print the image. SUB SCANNING DIRECTION (VERTICAL SCANNING DIRECTION) ! When the printer receives the PRINT signal, the polygon motor (M3) and the main motor (M1) rotate, and the main motor (M1) starts the paper feeding operation.

CHAPTER 5 ADJUSTMENT
PAGE 85
EPSON EPL 5800 Revision B 5.1 Adjustment ADJUSTMENT BY VOLTAGE CHANGE This chapter explains adjustment procedure. Adjustment should be done after components and parts are replaced. 1. With the power ON, put + terminal of the tester on VR1 and - terminal on the frame GND. 2. Adjust the position as the tester value becomes DC2.5 ± 0.1V. 5.1.1 Print Start Position Adjustment After replacing the main control board, make sure the sub scanning start position (d) is 4mm from the top edge of paper.

EPSON EPL 5800 Revision B 5.1.2 Interlock Switch Position Adjustment With the power ON, if the printer does not become ON when the top cover is closed, perform the position adjustment of interlock switch (S2) by the following procedure. 1. Open the top cover, and remove the left cover, the right cover and the front cover. 2. Loosen the screw fixing interlock switch (S2), and close the top cover completely. 3. Move the interlock switch (S2) up and down, and tighten the screw where the switch turns ON.

EPSON EPL 5800 Revision B 5.1.3 USB ID Input PROGRAM OPERATION EPL-5800 comes with the USB interface as a standard, and the PC connected to the EPL5800 via the USB interface identifies the printer by referring to the USB ID information unique to each printer. Since this USB ID information is stored on EEPROM on the main controller board of the printer, you have to re-define the ID information when you need to replace the main board for repair. C A U T IO N 1.
PAGE 88
EPSON EPL 5800 4. Revision B When the following window appear, input the serial number of the printer and click “Ok” button to store the USB ID information to an EEPROM on the main board of the printer. Take a note of the USB ID value displayed in the status window of the program, and this should be referred to when you check the inputted USB ID later on. USB ID CONFIRMATION When you re-define the USB ID, make sure to verify it with the following procedure.
