2008 Epson Artisan 800 / 700 Printer Service Manual (P/N SEMF08-004)

• 259-page PDF - Epson document number SEMF08-004, Revision C, issued February 27, 2009. Covers Epson Artisan 800, Stylus Photo PX800FW/TX800FW, Artisan 700, and the 700-series PX/TX variants. The manual body identifies those variants as PX700W/TX700W, while the cover prints PX700FW/TX700FW.
• Separates the two hardware families before repair work begins. The Artisan 800/PX800FW/TX800FW group has ADF and fax sections with touch-panel service, while the Artisan 700/PX700W/TX700W group has dedicated non-ADF scanner, button-operated panel, housing, main-board, and cable-routing procedures.
• Details printer-mechanism teardown and reassembly for the F6 printhead and ink path, carriage and CR/PF drive, paper-feed and eject mechanisms, CDR tray, sensors, frames and guides, waste-ink tray, and absorbent-pad assemblies.
• Provides symptom- and error-based fault isolation for the printer mechanism, scanner/ADF, ink and waste-ink paths, power and interfaces, duplex unit, wired/wireless network, and fax hardware. Dedicated charts address paper feed/ejection, abnormal noise, carriage movement, and print-quality faults.
• Covers Epson adjustment-program and manual setup work including EEPROM data copy, initial and MAC-address setting, top-margin, Bi-D, PW/first-dot, Head Angular, PF, PG and PG-offset work, BRS/PFP correction, AID and case-open checks, CR/PF belt tension, and applicable touch-panel calibration.
• Lists the specified service tooling, including Ink Supply Tube screwing tool 1508164, PG adjustment tool 1508165, Leak Check jig, Air Release jig, and Carriage Stopper jig.
• Reference layout: 94 numbered tables and 353 numbered figures, including the Printer Mechanism Block Diagram, Nozzle Layout, Motors & Sensors views, PG Positions/Cam, FFC/cable-routing drawings, and Connector Summary. The appendix explicitly excludes exploded diagrams and a parts list and refers that information to Epson SPI.

Operating principles and diagnostics

Built for repair shops and experienced owners working beyond routine cleaning, the manual first establishes how the mechanism is supposed to operate. The feature and operating-principles sections identify the six-color F6 printhead—called F6 Turbo II in the feature section and F6-Shrink in the mechanism description—and show its nozzle arrangement. They then map the PF and EJ rollers, carriage, ink system, decompression motor, photo/CD tray paths, encoders, and sensors. Separate printer, scanner, and ADF motor/sensor figures, along with the PG positions/cam diagram, help connect a symptom to the mechanism that produces it before the unit is opened.

Troubleshooting goes deeper than a list of LCD messages. The checkpoint tables are organized by occurrence timing and symptom, then link likely parts, connector or mechanical checks, remedies, and the matching disassembly section. There are dedicated charts for paper jams, paper-out and double-feed errors, abnormal noise, feed/eject failure, carriage movement, print quality, ink supply and waste ink, power and interface faults, duplex, and network problems. On fax-equipped models, the manual also covers logs, error-code interpretation, protocol traces, and post-repair send/receive/EXT-port checks using several shop test setups.

Disassembly, adjustment, and maintenance

Chapter 4 uses disassembly flowcharts and component-specific removal/reassembly sections rather than a generic chassis overview. It covers the housing, scanner/ADF, panel, main board, power supply, wireless LAN and card-slot boards, then continues through the printhead, ink system, carriage, and paper path. A transfer-parts checklist is provided for printer-mechanism replacement, and the 700-series procedures account for different housings, scanner cover, panel, main-board connector positions, and the absence of fax/ADF hardware. FFC and cable-routing drawings are especially useful after board, scanner, motor, or carriage repair.

The adjustment chapter is what makes the manual useful after parts have been changed. Its required-adjustment matrix ties each removed or replaced assembly to the necessary follow-up work, including data transfer, counters, ink charge, print-pattern calibration, motor compensation, sensor checks, and final check printing. BRS/PFP procedures specify the required base scale and supported scanner configurations; manual PG and belt-tension work identifies the required jigs, gauges, and fixtures. The maintenance section then documents printhead cleaning, waste-ink pad replacement and counter reset, and model-specific lubrication points with Epson-specified greases.

The cautions also flag genuine repair traps. Incorrect waste-ink tube placement can cause leakage, while leaving the Transmission Arm away from the Ink System position can keep the carriage locked and produce a fatal error; scanner work calls for protecting the rod lens array and timing belt from damage or grease contamination. Disconnect AC power before opening the chassis, use ESD protection around the boards, and energize the printer only when a listed test requires it.
