CHAPTER 2 OPERATING PRINCIPLES
EPSON Stylus PHOTO 810/820/830 Revision B No porous pad in cap 2.1 Overview Cap unit with wiper This section describes the operating principles of the Printer mechanism and electrical circuit boards. Like the previous printers (Stylus COLOR 480/580), the Stylus PHOTO 810/820 has only the following two circuit boards and does not have the control panel board.
EPSON Stylus PHOTO 810/820/830 Revision B Following explains the basic components for the Printhead. 2.1.2 Printhead The Printhead uses the same U-CHIPS type as the previous printer (Stylus COLOR 680), and makes it possible to perform multiple shot printing and variable dot printing. PZT PZT is an abbreviation of Piezo Electric Element.
EPSON Stylus PHOTO 810/820/830 Revision B 2.1.2.1 Printing Process 2.1.2.2 Printing Method This section explains the process which the Printheads of On-Demand inkjet printers eject ink from each nozzle. For printing dot system, the Stylus PHOTO 810/820 has the following two kinds of printing mode. 1. 2. Normal state : When the printing signal is not output from the Main board (C418 Main/Main-B, C483/C484 Main), or the PZT drive voltage is not applied, the PZT does not change the shape.
EPSON Stylus PHOTO 810/820/830 Revision B 2.1.3 Carriage Mechanism The Carriage mechanism consists of CR motor, Carriage unit (including the Printhead and CR guide shaft), CR timing belt and CR home position sensor (HP/PE sensor) etc. Following figure shows you each component for the CR mechanism. HP/PE sensor CR motor HP detection lever The drive of the CR motor is transmitted to the CR unit via the CR timing belt. And, the CR home position is detected with the HP/PE sensor.
EPSON Stylus PHOTO 810/820/830 Revision B The drive of the PF motor is transmitted to the LD roller shaft and the PF roller through gears for the Paper loading/feeding mechanism. The Paper loading mechanism plays a role in loading a paper from the ASF unit to the PF roller. And also, the Paper feeding mechanism plays a role in feeding a paper loaded from the ASF unit. The functions of the Paper loading/feeding mechanism varies depending on the rotational direction of the PF motor as the table below. 2.1.
EPSON Stylus PHOTO 810/820/830 Revision B For your reference, the top or the end of a paper is usually detected with the HP/PE sensor. In case that the HP/PE sensor cannot detect the top of a paper in the paper loading sequence, the printer indicates the "Paper out error". If the HP/PE sensor cannot detect the end of a paper in the paper feeding sequence, the printer indicates the "Paper jam error". As for the details, refer to Chapter 3 "Troubleshooting". 2.1.4.
EPSON Stylus PHOTO 810/820/830 Revision B Step 1 (ASF Home position) Step 2 Hopper & Paper return plate condition LD roller shaft Hopper & Paper return plate condition LD roller When the PF motor pinion ASF hopper release lever gear rotates CW direction Paper return plate (Right side view), the Hopper Change lever pushes Compression down the Clutch lever as Torsion spring 29.1 spring 2.50 right figure and the Clutch ASF frame lock tooth is disengaged from the Clutch gear.
EPSON Stylus PHOTO 810/820/830 Revision B Step 4 Step 3 Hopper & Paper return plate condition Hopper & Paper return plate condition 1 1 The PF motor pinion gear rotates CW direction (right side view), and the drive of the PF motor is transmitted to the LD roller shaft through the Clutch lock tooth and the Clutch gear. After the LD roller pushes down the Paper return plate into the ASF frame, the ASF hopper is released by the tension force of the Compression spring 2.50.
EPSON Stylus PHOTO 810/820/830 Revision B 2. 2.1.4.2 Paper Feeding Mechanism The Paper feeding mechanism consists of PF motor, PF roller, Paper eject roller *1, Paper end sensor (HP/PE sensor) etc. The Paper feeding mechanism feeds a paper loaded from ASF unit by using pairs of rollers. *1 1. Another pair is the Paper eject roller and the Star wheel which is assembled on the Front frame. The drive of the PF motor is transmitted to the Star wheel through the Paper eject roller.
EPSON Stylus PHOTO 810/820/830 Revision B 2.1.5.1 Capping Mechanism 2.1.5 Ink System Mechanism The Ink system mechanism consists of Pump mechanism with Carriage lock mechanism and Capping mechanism with Wiper mechanism. Following table lists the function for each mechanism. Table 2-4. Function for each mechanism Mechanism 1. Function This is to cover the surface of the Printhead with the cap in order to prevent the nozzle from increasing viscosity.
EPSON Stylus PHOTO 810/820/830 2. Revision B Wiper with the Cap unit The wiping operation is controlled by the CR unit movement. This operation is usually performed with every CL sequence which is to absorb the ink from the ink cartridge, the ink cavity by the Pump unit. Following figure shows you the mechanism for the wiping operation. Step 2 Step 1 When the CR unit is in the home position, the hook of the Slider lock lever is not latched to the dent of the Cap frame.
EPSON Stylus PHOTO 810/820/830 Revision B 2.1.5.2 Pump unit mechanism 1. Ink eject operation (usual operation) The ink is absorbed from the ink cartridge, the ink cavity and is ejected to the Waste drain ink pad from the cap when the ink tube is pressed by a roller in the Pump unit. The PF motor also controls the Pump unit mechanism (including the Change lever) as well as the Paper loading/feeding mechanism. The drive of the PF motor is always transmitted to the Pump unit.
EPSON Stylus PHOTO 810/820/830 2. Carriage lock operation by the Change lever Unlike the previous printer (Stylus COLOR 680), this printer does not have the Carriage lock lever with the Wiper. Instead of the Carriage lock lever, the Change lever is set to the front side of the printer while the CR unit is in the CR home position. (As for the detailed mechanism for setting the Change lever, refer to Figure 2-8 Step 2) Revision B 2.1.
EPSON Stylus PHOTO 810/820/830 Revision B CL1" - Ink absorption Black Ink: 0.52g, Color Ink: 2.58g - Wiping operation Wipes the nozzle plate by the rubber part on the Cap unit. - Flashing operation Prevents color from mixing and stabilizes ink surface inside the nozzle. cleaning period is over the specific period, the printer performs the timer cleaning automatically. In this time, the printer stores the timer command in 02 , 03 , 04 and 05 of the EEPROM. Maximum 0.
EPSON Stylus PHOTO 810/820/830 Revision B 2.2 Electrical Circuit Operating Principles Printer mechanism The electric circuit of the Stylus Photo 810/820/830 consists of the following boards.
EPSON Stylus PHOTO 810/820/830 Revision B 2.2.1.1 C417 PSB/PSE board 2.2.1 P/S board The power supply boards of the Stylus PHOTO 810/820/830 uses a RCC (Ringing Chalk Converter) circuit, which generates +42VDC for drive line and +5VDC for logic line to drive the printer. The application of the output voltage is described below. +42VDC +5VDC Table 2-6.
EPSON Stylus PHOTO 810/820/830 1. Revision B Regardless of the state of the power switch (On or OFF), the voltage is always applied to the primary side of the power supply board from the moment or at the state that AC-plug is plugged in. At this time, F1 plays a role of preventing AC100V from coming into the F1. L1 also prevents high harmonic wave noise generated in the RC circuit filter which consists of C1 from going out, and eliminates the noise from outside here. 2.
EPSON Stylus PHOTO 810/820/830 Revision B 2.2.1.2 C482 PSH board +42VDC +5VDC Signal from Main baord 1. Regardless of the state of the power switch (On or OFF), the voltage is always applied to the primary side of the power supply board from the moment or at the state that AC-plug is plugged in. At this time, F1 plays a role of preventing AC250V from coming into the F1.
