2 CHAPTER OPERATING PRINCIPLES
PAGE 33
EPSON Stylus Photo 870/1270 Revision B 2.1 Overview This section describes the operating principles of the printer mechanism and electrical circuit boards. The major components of the EPSON Stylus Photo 870/1270 are: " Printer mechanism: Stylus Photo 870: M4T10 Stylus Photo 1270: M4S60 " Main board: C304MAIN Board The basic structure of the printer mechanism is mostly common to the Stylus COLOR 400, except that the Stylus Photo 870/1270 uses a Pump/ ASF motor.
PAGE 34
EPSON Stylus Photo 870/1270 Revision B " Ink Cartridge 2.1.1 Printhead Mechanism An ink cartridge stores ink to be supplied to the printhead. The printhead mechanism operating principles of the Stylus Photo 870/ 1270 are basically the same as for the previous EPSON ink jet printers. This printer, however, employs a newly developed ink and improved printhead driving method to provide a higher print quality and faster printing speed than ever.
PAGE 35
EPSON Stylus Photo 870/1270 Revision B 2.1.2 Carriage Mechanism The carriage mechanism of the Stylus Photo 870/1270 is composed of the carriage motor (CR motor), carriage guide shaft, platen gap adjustment/ parallelism adjustment mechanism, carriage lock mechanism, and so on. Photo Coupler 2.1.2.1 Carriage Motor (CR Motor) CR Motor Carriage Unit Linear Encoder The carriage mechanism this printer is mostly the same as for other ink jet printers’ except it uses a DC motor as power source.
PAGE 36
EPSON Stylus Photo 870/1270 Revision B 2.1.2.2 Platen Gap (PG) /Parallelism Adjustment Mechanism 2.1.3 Paper Feeding Mechanism The PG adjust lever is attached to the left end of the carriage guide shaft. When the carriage guide shaft, which has an eccentricity, rotates as the adjustment lever moves, it narrows or widens the distance (=PG: from 1.2 mm to 2.1 mm). This mechanism enables the user to print with a correct PG according to print result or other conditions such as paper curl.

PAGE 38
EPSON Stylus Photo 870/1270 Revision B 2.1.3.1 CR Lock Mechanism The carriage lock mechanism prevents the carriage from being left uncapped for a long time, which is usually caused by vibration during printer transportation, user’s mishandling of the printer, and so on. If the carriage unit is left uncapped for a long time, ink on the printhead surface dries gradually and, eventually, ink can not flow to nozzles.
PAGE 39
EPSON Stylus Photo 870/1270 Revision B 2.1.4 Paper Loading Mechanism 2.1.4.1 Drive Transmission to the ASF Unit The paper loading mechanism loads paper at the ASF unit and feeds paper to the PF rollers. The ASF unit is the same as in previous models. A 4-phase 48-pole PM type stepping motor is used as the ASF/Pump motor to drive ASF. Drive sent from this motor is transmitted to the ASF side and Pump side via the disengage mechanism (DE mechanism). See Figure 2-5 for the ASF/Pump motor specifications.
PAGE 40
EPSON Stylus Photo 870/1270 Revision B 2.1.4.2 Paper Loading Operation Multiple paper loading prevention mechanism is included in the ASF unit to ensure steady paper loading. To prevent any paper from falling from the paper set position into the paper path, the paper return lever pushes paper that may have fallen off back onto the hopper. After this motion is completed, the LD roller starts loading paper.
PAGE 41
EPSON Stylus Photo 870/1270 Revision B " Torque transmission to the pump unit 2.1.4.3 Pump Mechanism The pump mechanism absorbs ink from the printhead and the cap assembly. The wiper for head cleaning is included in the cap assembly. The torque from the ASF/Pump motor is transmitted to the pump mechanism as described below: The pump mechanism is driven by the ASF/Pump motor, a 4phase 48pole PM type stepping motor. See Table 2-5 for the ASF/Pump motor specifications.
PAGE 42
EPSON Stylus Photo 870/1270 Revision B 2.1.4.4 Capping Mechanism The capping mechanism, which is driven by the pump unit, caps the printhead closely to maintain air tightness inside the cap. This operation is required to vacuum ink from the ink cartridges, printhead, and cap. Also, to moisten the inside of the cap while the printer power is off, this mechanism works to keep the cap and the printhead surface in a tight contact. This function prevents ink from clogging while the printer is not in use.
PAGE 43
EPSON Stylus Photo 870/1270 Revision B 2.2 Electrical Circuit Operating Principles The electric circuit of the Stylus Photo 870/1270 consists of the following: " Control circuit board: C304MAIN The power supply board for the Stylus Photo 870 and Stylus Photo 1270 is C298PSB/PSE. It uses a RCC switching regulator system, and supplies +42VDC and +5VDC to the printer mechanism and control board. " Power supply board: C298PSB/PSE " Panel board: 2.2.
PAGE 44
EPSON Stylus Photo 870/1270 Revision B Figure 2-11 shows the block diagram for the C298PSB/PSE board. The C298PSB/PSE Board produces the +42VDC and +5VDC using AC power as described below: 1. Regardless of the power switch’s on/off condition, 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. F1, a fuse, prevents AC100V from flowing into the circuit.
PAGE 45
EPSON Stylus Photo 870/1270 Revision B 2.2.1.2 Protection Circuits 2.2.1.3 Power Supply Control Function The C298PSB/PSE board has the various protection circuits to stop voltage outputs if an abnormal condition relating to the control circuit or the printer mechanism’s duty occurs. Since this printer has the power switch in the secondary circuit, even if its power is turned off through the operation panel, it can continue to supply voltage to the +5VDC line and +42VDC line for about 30 seconds.

PAGE 48
EPSON Stylus Photo 870/1270 Revision B 2.2.2.1 Printhead Driver Circuit The printhead driver circuit includes: ! Common driver IC IC10 (E09A14RA)/IC10 (E09A15KA) directly attached to the C304MAIN board. F1 ! Nozzle selector IC (IR2C95F or SED6125T0A) on the head board. The common driver generates reference drive waveforms according to the output signals from ASIC on the C304MAIN board.
PAGE 49
EPSON Stylus Photo 870/1270 Revision B 2.2.2.2 Reset Circuit 2.2.2.3 Motor Driver Circuit Reset circuits are attached on the C304MAIN board to monitor the two voltages: +5V for the logic line and +42V for the drive line. When each circuit detects abnormality on the corresponding line, it resets CPU and ASIC to prevent the printer from operating abnormally. IC5 RTC-9820SA, the reset circuit IC attached directly on the main board, monitors both +5V and +45 lines but can reset them independently.
PAGE 50
EPSON Stylus Photo 870/1270 Revision B determine the CR position and the direction in which the CR moves. The slave CPU outputs specified control signals to the motor driver. The motor driver IC18 then outputs CR motor drive current to the CR motor. Unlike stepping motors, the DC motor that drives the carriage can not detect the current carriage position by referring to the pulses given. For this reason, a linear scale is attached along the carriage operation range to detect the carriage position.
PAGE 51
EPSON Stylus Photo 870/1270 Revision B ! PTS (Print Timing Signal) production The circuit produces PTS signal (cycle: 1/360 inches) by dividing waveform cycles of Phase A. The print timing signal is used to eject ink at a correct timing. 1/180” PF motor driver circuit A DC motor is used as the PF motor in this printer. In addition to the CPU and ASIC, a slave CPU is mounted on the C304MAIN board.
PAGE 52
EPSON Stylus Photo 870/1270 Revision B attached on the Gear 76 to detect paper feed amount. The loop scale encoder sensor outputs two kinds of TTL level pulses Phase A and Phase B to ASIC (IC8). 2.2.2.4 ASF/Pump Motor Driver Circuit ASF/Pump motor is a PM type stepping motor.
PAGE 53
EPSON Stylus Photo 870/1270 Revision B 2.2.2.5 EEPROM Control Circuit 2.2.2.6 Sensor Circuit Since EEPROM is a nonvolatile memory, it keeps information written if the printer power is turned off. It stores such information as adjustment values, factory values, and printer status values. The Stylus Photo 870/1270 has the following five sensors to detect printer’s status.
PAGE 54
EPSON Stylus Photo 870/1270 Revision B Each sensor’s functions and operating principles are as described below: " PE sensor The PE sensor is located at the bottom right edge of the top frame in the printer mechanism. It detects paper on the rear paper guide using a photo sensor and PE sensor lever that are included in the sensor. When paper is present, the PE sensor lever does not cut in between the photo sensor terminals. So it outputs a LOW signal to the ASIC.
