Chapter 2 Operating Principles 2.1 Overview................................................................................................................2-1 2.2 Printer Mechanism Operating Principle .............................................................2-1 2.2.1 Printer Mechanism ................................................................................................................. 2-1 2.2.2 Printing Mechanism ...............................................................................
EPSON Stylus COLOR 3000 2.1 Overview This chapter describes the operating principle of the printer mechanism and electrical circuit. 2.2 Printer Mechanism Operating Principle 2.2.1 Printer Mechanism The printer mechanism of this printer is composed of the printhead unit, paper feeding mechanism, ( arriage) mechanism and the pump mechanism. The block chart for the printer mechanism is shown in Figure 2-1. The printer mechanism has 3 motors: motor, PF (Paper Feed) motor and pump motor.
Operating Principles 2.2.2 Printing Mechanism The printing method used for this printer is On-demand ink jet, same as for other EPSON ink jet printers. However, use of the new type of printhead improves print quality and speed. The printing mechanism has 2 parts: printhead and ink cartridge which is filled with ink. 2.2.2.1 Printhead Structure The printhead for this printer has the black and color printheads. The structures of the printheads are basically the same except for the nozzle configuration.
EPSON Stylus COLOR 3000 2.2.2.2 Printing Process Steps bellow describe how the ink is ejected from each nozzle with the on-demand ink jet system. Normal state No print signal is applied to the PZT (Piezo electric element). In this state, the PZT does not displace and no pressure is added to the ink inside the cavity. Therefore the pressure in the cavity is kept at a constant level.
Operating Principles 2.2.3 Carriage ( ) Mechanism The mechanism is composed of the unit, timing belt, guide shaft, paper eject frame, (Home Position) sensor and motor. The motor sends torque to the timing belt to move the unit in the both right and left directions along the paper eject frame and guide shaft. A stepping motor used for the motor enables the unit to move and stop at any position.
EPSON Stylus COLOR 3000 2.2.4 Paper Feed Mechanism The paper feed mechanism of this printer consists of the integrated ASF (Auto Sheet Feeder) mechanism, tractor mechanism, PF (Paper Feed) motor, front/rear PE (Paper End) sensors, PF roller, paper guide mechanism, paper eject unit, and PF motor drive disengage mechanism. The torque from the PF motor drives the paper load mechanism, paper feed mechanism and paper eject mechanism.
Operating Principles 2.2.4.1 ASF (Auto Sheet Feeder) Mechanism When the printer is not printing, the motor drive disengage mechanism switches the torque sent from the PF motor to the LD rollers in the mechanism via the planetary gear based on the detected position of the unit. The roller shaft has 2 cams on the right and left ends. They push down the paper support to make the paper surface come in contact with the rollers.
EPSON Stylus COLOR 3000 2.2.4.2 Tractor Mechanism Torque sent from the motor to the roller is transmitted to the tractor gear via disengage mechanism operated with the release lever. When the release lever is set to the tractor side, the release sensor detects the condition and torque transmission to the ASF mechanism is cut off as a result. Tractor Gear Release Lever Tractor Disengage Gear Rear PE Sensor PF Roller PF Motor PF Motor Pinion Gear Figure 2-7. Tractor Mechanism 2.2.4.
Operating Principles 2.2.5 Platen Gap ( ) Adjust Mechanism The adjust mechanism, located at the top right of the printer cover, allows the user to set the proper platen gap (distance between paper and nozzle surface) for the paper thickness to prevent ink smudging. The adjustment mechanism consists of the adjust lever, guide shaft, and parallelism adjust bushings. Switching the lever from “0” to “1” turns the guide shaft which joins to the lever.
EPSON Stylus COLOR 3000 2.2.6 Ink System The ink system for this printer is composed of the following mechanisms. Ink cartridge Pump mechanism Capping mechanism Waste ink drain pads Wiping mechanism Figure 2-9 shows the block chart of the ink system. flowchart Ink Cartridges Cleaner Head for Black and Color Inks CR Unit Clutch Unit Pump Motor Combination Gear Air Valves Pump 1 Pump Unit Gear Pump 2 Waste Ink Drain Pads Figure 2-9. Ink System Mechanism Rev.
Operating Principles 2.2.6.1 Pump Mechanism The pump mechanism, composed of the pump motor and pump unit, absorbs viscous ink in the printhead nozzles and drains it to the waste ink drain pad through the cap. Since this printer has only one pump, it uses the pump for both black and color inks by alternating the rotational direction of the pump motor. 1 When the pump motor rotates forward * it absorbs black ink. On the other hand, it absorbs color ink with 2 backward rotation * .
EPSON Stylus COLOR 3000 2.2.7 Capping Mechanism Ink around head nozzles loses moisture If they are left exposed while the printer is in non-printing or power off status. Therefore the printheads must be capped to avoid increasing viscosity due to dried nozzles. The caps are individually equipped for the black and color printhead. When the moves right from the home position, the cap holder also shifts right and strikes the right frame. This motion opens the air valve and the air in the cap is release.
Operating Principles 2.2.7.1 Wiping/CR Lock Mechanism The wiping operation removes the ink and dust adhered around the nozzles. This is operated during a cleaning sequence. When the pump motor rotates backward, the torque sent via the head cleaner (wiper) drive gear and the clutch moves the head cleaner to the printhead route. The unit then begins to move right and left to wipe the nozzle surface against the head cleaner.
EPSON Stylus COLOR 3000 2.3 Electrical Circuit Operation Principles This printer consists of the following circuit board: C203 MAIN board C178 PSB/PSE board C203 Panel board Head driver circuits are directly attached to the black and color printheads. Figure 2-13 shows the block diagram of the electrical circuit. C203 PNL C172 PSB/PSE C203 MAIN Printer Mechanism Unit CR/PF/Pump Motors +5VDC +42VDC CR Unit Color Head Driver Circuit Black Head Driver Circuit Figure 2-13.
Operating Principles Figure 2-14 illustrates the electrical circuit diagram.
EPSON Stylus COLOR 3000 2.3.2 MAIN Control Board This printer uses MAIN for the main control circuit board. It consists of the following: 16-bit H8S/2655 (IC5) Runs at 19.66 MHz 2 gate arrays E05B33 (IC6) Manages interfaces, motors and printheads. E05B45 (IC16) P-ROM, DRAM and MROM Drivers Produces common voltage for printheads Drives motors. Table 2-8 and Figure 2-15 show the allocated functions for major components and the main control circuit block diagram, respectively.
Operating Principles C.G.
EPSON Stylus COLOR 3000 2.3.2.1 Reset Circuits The MAIN board contains two reset circuits: for logic line (+5 ) and power line (+42 ). Reset IC M51955BFP (IC3) monitors the +42 line. It outputs /NMI signal to the and the gate array to cut off the power line for the motors when the voltage level drops below 33.2 . Reset IC RST592D (IC9) monitors the +5 V line and sends low pulse when the voltage level drops below 4,2 .
Operating Principles Thermistor Thermistor is attached onto the color printhead to monitor the temperatures around the printhead. It functions to avoid change in ink viscosity, which affects printing result. The signal output from the sensor is directly transmitted to the analog port of the . ASF_PW : Output from the ASF PW (Paper Width) sensor. The ASF sensor uses a sliding potentionmeter. (The maximum resistance :10kΩ.) It is attached to the left edge guide in the ASF hopper assembly.
EPSON Stylus COLOR 3000 ASF_PQ :Output from the PQ (Paper Quantity) sensor. The paper quantity sensor uses a sliding potentionmeter. (The maximum resistance:10 ohms) The sensor ,attached to the right edged guide in the hopper assembly, detects the paper quantity between the maximum of 15 mm and the minimum of 3 mm. The detected quantity is converted into the corresponding resistance and the information is transferred to the analog port of the . When the 2 sensor detects the condition of 3.
Operating Principles 2.3.2.3 Motor Driver Circuits The gate array E05B45 produces the phase data (CRDA0-5) for the CR motor and sends it to 2-channel D/A converter in parallel data. When the phase-change trigger signal (CRTRG) is sent from the to the gate array, the A/B phase-change signal (CRDASEL) is output. Then the A-phase-data and B-phase-data are transferred to the channel A and channel B in the D/A converter, respectively.
EPSON Stylus COLOR 3000 2.3.2.4 PF Motor Driver Circuit The motor for this printer operates the following: Paper loading Paper feeding The gate array E05B33 (IC6) outputs the phase drive control signals (PFAPH and PFBPH), phase data signal (PFA0/1 and PPFB1/0) and voltage reference data (PFV) to the driver IC UDN2917EB (IC17). The driver IC then controls the phase current based on the voltage reference data. This sequence enables the micro step with a minimum of 1/720 inch at 2-2 phase.
Operating Principles 2.3.2.5 Printhead Driver Circuit This printer has 2 separate printhead driver circuits for the black and color printheads. Each circuit has the common voltage driver circuit attached to the circuit control board, and the nozzle selector circuit attached to the printhead. The each of the black and color common driver circuits is composed of the hybrid IC H8D2813E (IC22) and the terminal transistor.
EPSON Stylus COLOR 3000 Common driver circuit for the black printhead Gate array E05B33 (IC6) sends serial data to the head nozzle selector circuit on the printhead to select nozzles to be activated. Then the data is transferred to the common driver on the control board to drive all PZT that correspond to each nozzle.
Operating Principles Color printhead nozzle selector circuit The operating principle for the color printhead is the same as for the black printhead except that color print is performed with data for 3 different colors: yellow, cyan, and magenta. The operating principle for the color printhead is as described below: Nozzle selector circuit The nozzles for the color printhead are divided into 3: for yellow, cyan, and magenta with 64 nozzles for each of them.
EPSON Stylus COLOR 3000 Special printing This printer has the following special printing modes to print various types of graphic images. Each mode is selected through the printer driver based on the selected type of the paper and print quality. Double firing normal dot / Single dot printing mode This printer forms 1 dot with double ink ejection in the ANK or bitmap image mode. In the raster graphics mode which requires a high-resolution printing, however, forms 1 dot with a single ink ejection.
Operating Principles 2.4 Ink System Management This section explains how the ink system is controlled to protect the printheads and to ensure high print quality.
EPSON Stylus COLOR 3000 2.4.2 Counters The EEPROM on the control board stores the values for the following counters to manage the ink system: Protect Counter A This counter counts total amount of drained ink. If the counter value exceeds 75,000, the maintenance error occurs and the current printing job stops as a result. (Refer to Section 1.5.8.) The occurrence of this error requires ! clear operation and waste ink drain pad replacement. (Refer to Section 1.5.1 and Chapter 3.
