EPSON Stylus Pro 7600/9600 Revision A 2.2 Print Mechanism Components Table 2-1. Printer Mechanism Components (continued) The major electrical parts used in the printer mechanism of this printer are as shown below. Hereafter, we will explain each printer mechanism focusing on these parts. Table 2-1. Printer Mechanism Components Part Drive voltage Description Refer to The number of nozzles: 96 Nozzle x 7 colors Head thermistor +3.
EPSON Stylus Pro 7600/9600 Revision A 2.2.1 Carriage (CR) Mechanism Stylus Pro 7600/9600 is equipped with a unique carriage mechanism which enables reliable, high-precision movement of the on-carriage head for high-precision printing in the printing range (= carriage movement range). P_EDGE sensor Carriage CR_HP Sensor and Flag Encoder Sensor and Timing Fence HD-SLID Sensor and Slide Gear Figure 2-1.
EPSON Stylus Pro 7600/9600 Revision A CARRIAGE MOVING UNIT In place of the carriage holding system in which 2 CR guide shafts extending in the column direction were used, as in the conventional models, a structure with the carriage mounted via multiple rollers (bearings) on a CR guide rail made of a square extruded aluminum pipe is used.

EPSON Stylus Pro 7600/9600 Revision A HD_SLID (Head Gap Home Position Detection) Sensor This sensor detects the mechanical home position when the position of the subcarriage (head height from the paper surface) on the carriage undergoes change. A reflective type photosensor is used and the position of the flag on the gear mounted on the camshaft is detected. The cam is so shaped as to realize the four head positions relative to the mechanical home position.
EPSON Stylus Pro 7600/9600 Revision A P_EDGE (Paper Width Detection) Sensor This sensor, mounted at the left side of the cutter unit of the carriage, detects paper edges by moving the carriage. It detects four points of paper edges, namely, left and right points on the front edge and a front point on the left and right edges of the paper. Each position is calculated from the difference in reflection value between the platen and the paper. A reflective type photosensor is used.
EPSON Stylus Pro 7600/9600 Revision A Paper size detection sequence (left and right edges) Error display: Set the paper correctly C H E C K P O IN T Transition to this sequence is allowed only at paper initial. At inter-page skew checking, transition to Simplified detection sequence for left and right edges (skew check) (p.111) takes place. Solid Line: Paper Broken Line: Printable Area Right edge detection position Note "*1": Paper presence position = 215.4 mm Paper absence position = 132.

"*2": Printing area MIN position =142.9 mm –4.0 mm (Reserved width) A4 size (210.0 mm) – 20.0 mm = 190.0 mm When the paper width detection function is turned off, left and right edge detection (skew check) is not carried out.
EPSON Stylus Pro 7600/9600 Revision A Cutter Solenoid This DC solenoid controls the cutting pressure of the roll paper cutter. It also unlock the carriage. This function can be set On or Off using the Panel buttons. Cutter Solenoid Carriage Roll Paper NOTE: See “1.2.6.3 Cutting Specification” (p.22) Cutter Figure 2-10.
EPSON Stylus Pro 7600/9600 Revision A PF motor 2.2.2 Paper Feed Assembly This printer uses friction feed to carry out highly precise feeding of roll paper and cut sheets, and comprises a unique paper feed mechanism. The paper feed mechanism unit is configured from a grid roller (one piece construction), and pressurizing and follower roller assemblies mounted on the back of the CR guide rail opposite the front surface. The PF motor is a DC motor.
EPSON Stylus Pro 7600/9600 Revision A Paper Suction Fans The printer is equipped with suction fans in the lower space in the rear. The space in the column direction behind Paper Guide L2 is divided into 2 compartments (Stylus Pro 7600) or 3 compartments (Stylus Pro 9600), and one fan is mounted in each compartment.
EPSON Stylus Pro 7600/9600 Revision A 2.2.3 Cleaning Mechanism Cleaning Mechanism (Maintenance ASSY) The cleaning mechanism in this printer is compatible with the cleaning mechanism in the Stylus Pro 5000/9000. The cleaning mechanism is located on the right side of the printer. The waste ink from the cleaning mechanism is channeled to the waste ink pad (Maintenance Tank) in the lower right side through the tube.
EPSON Stylus Pro 7600/9600 Revision A Cap assembly Table 2-7. Explanation of Operation (continued) When not printing, the print head (should) rest on the cap assembly to ensure that the nozzles don't clog. Also, the print head is in the capped position during ink charging, cleaning, and so on. Flushing box Flushing (dummy printing) is performed over the flushing box, and the flushed ink flows through the pipe to the waste ink pads.
EPSON Stylus Pro 7600/9600 Revision A 2.2.4 Ink Supply Mechanism Stylus Pro 7600/9600 is so constructed that the 7 cartridges for different colors are installed in the respective ink holders (I/H) in the left area of the printer. A projection and unique marking are placed on each color ink cartridge case to prevent wrong insertion so that the correct cartridge is inserted in the right direction.
EPSON Stylus Pro 7600/9600 Revision A 2.2.5 Others COVER SENSOR Panel Unit In order to detect whether the front cover on the lower front of this printer is open or closed, a cover sensor is mounted on the printer on the left side where the front cover opens and closes. Cover Sensor This sensor carries out control of operating and stopping of the CR motor and PF motor drive circuits via the MAIN board's logic circuit after detecting the cover's status.
EPSON Stylus Pro 7600/9600 Revision A 2.3 Outline of Control Circuit Board Note "*": Stylus Pro 7600: IC4/6 only (32MByte) Stylus Pro 9600: IC4/6 and IC600/601 (64MByte) This section describes the operation of C472MAIN Board, which controls and drives the printer mechanism of Stylus Pro 7600/9600. NOTE: For details of each circuit, refer to Chapter 7 Appendix (p.281). Explanation of major elements on C472MAIN Board Table 2-8.
EPSON Stylus Pro 7600/9600 Revision A 2.4 Outline of Power Supply Circuit Board There are three control signals between the C472MAIN Board and the Power Supply Circuit Board. Table below describes details of the control signals: The 100 V AC power from the wall outlet is supplied via the power cable, an accessory of Stylus Pro 7600/9600, into the Inlet of the printer and to the Power Supply Circuit Board.
