2008 Epson WorkForce 600 / Stylus OFFICE TX600FW / Stylus OFFICE BX600FW / Stylus SX600FW / ME OFFICE 700FW Printer Service Manual (SEMF08-006)

This Epson service manual, SEMF08-006, Revision A, covers the 2008 WorkForce 600, Stylus OFFICE TX600FW, Stylus OFFICE BX600FW, Stylus SX600FW, and ME OFFICE 700FW color inkjet printers.

• Printer mechanism: O6-chips Turbo II printhead replacement, carriage and paper-feed disassembly, ink-system service, and reassembly checks.

• Scanner and ADF: CIS/scanner carriage removal, scanner and ADF motor replacement, feed-roller service, and document-sensor diagnosis.

• Fault isolation: LCD error tables, fatal-error troubleshooting, print-quality checks, and motor and sensor electrical reference tables.

• Boards and communication: Main board, power supply, and Wireless LAN module replacement, network troubleshooting, FAX logs, and EXT-port function checks.

• Adjustments and maintenance: EEPROM data copy, Head ID entry, alignment patterns, waste ink pad replacement and counter reset, cleaning, and lubrication.

• Service illustrations: Printer Mechanism Block Diagram, main-board connector layout, disassembly flowcharts, cable-routing views, and numbered exploded drawings.

The manual is written for experienced repair technicians; its safety instructions specify that repairs should be performed by Epson-certified technicians.

Fault Isolation, Network Checks, and FAX Tests

Fatal-error tables connect startup symptoms with scanner wiring, carriage encoders, motors, and the main board. These checks help distinguish a scanner initialization fault from a carriage or paper-feed problem before an assembly is replaced.

Network diagnosis addresses wired/wireless selection, access points, and IP settings. FAX coverage includes protocol traces, communication error codes, and post-repair send/receive tests using a telephone line simulator or PBX.

The Connector Layout of the Main Board Unit and service views identify connections such as CN9, CN10, and CN17. Sensor pin assignments are provided, but full board-level circuit schematics are not included.

The Nozzle Check Pattern and Sample of Network Status Sheet support status checks. Product descriptions also explain ink-level bars, print modes, and paper-feed specifications.

Print Mechanism, Scanner, and ADF Repair

Disassembly coverage extends to the pump/Ink System Unit, waste ink pads, EJ Roller, and Star Wheel Holder Assy. Assembly photos identify fastener torques, cable folds, ferrite-core positions, and alignment points.

Main-frame handling precautions explain how resting the assembly on the Upper Paper Guide rollers can damage those rollers or the printhead nozzle surface. Scanner carriage precautions address damage to the Rod Lens Array and the taped FFC.

The cartridge-cover hinge and EJ roller's Spur Gear 51.5 are identified as nonreusable after removal. Numbered exploded drawings help locate assemblies; the appendix does not include a separate itemized parts list.

EEPROM Transfer, Alignment, and Waste Ink Service

The required-adjustment table links replacement parts to subsequent calibration. EEPROM data copy and the MAC Address Setting Flowchart cover readable and unreadable original boards, including MAC address entry when data cannot be transferred.

Head angular, Bi-D, PF, PF-band, and margin adjustments include pattern-evaluation guidance. Several adjustment headings retain TBD labels in Revision A, and software operation is referred to the Adjustment Program's onscreen instructions. Adjustment Program software is not included with the PDF.

Maintenance links waste ink counter reset to pad replacement. Lubrication guidance distinguishes G-45 for the scanner guide rail, G-71 for carriage contact areas, and G-74 for the front paper guide's EJ roller contact points.

Internal power-supply and circuit-board work requires the manual's electrical-isolation and static-protection precautions.

Examples of Motor and Sensor Reference Values

These figures are a small sample of the electrical specifications in the manual.

The printer CR and PF motors have a specified driver-IC voltage of 42 VDC ±5%. Scanner-motor coil resistance is 38 Ω ±10% for MITSUMI units and 43 Ω ±10% for OKI units, both at 25°C.

For the PE sensor at CN7 pins 1 and 2, the reference signal is below 0.4 V without paper and above 2.4 V with paper present. The troubleshooting chapter cautions that resistance alone is unsuitable for diagnosing the printer's DC carriage and paper-feed motors.

Searchable Text, Bookmarks, and PDF Contents

Navigation and drawing detail: Body text is searchable, with embedded bookmarks for chapters and subsections. Text within some software screenshots is not searchable. Small callouts in connector and exploded views are readable when enlarged.

Supplied as one printable, English-language, 175-page PDF. That total already includes 7 preliminary pages, 160 pages covering Chapters 1-6, and an 8-page appendix containing six exploded-diagram sheets.
