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

Epson’s color inkjet printer service manual, P/N SEMF08-004, Revision C, issued February 27, 2009, covers the Artisan 800 and 700 and the Stylus Photo PX800FW, TX800FW, PX700W, and TX700W. The cover uses PX700FW and TX700FW for the printers identified as PX700W and TX700W in the model tables and repair sections.

Print Mechanism, Scanner, and Fax Service

This selection of service topics covers the main repair work. Other sections cover PictBridge setup and CompactFlash card-slot checks.

• Fault isolation: Symptom and error charts for paper feed and ejection, abnormal noise, carriage movement, print quality, ink supply, power, interfaces, and the optional duplex unit.

• Print mechanism: Removal and reassembly of the F6 printhead, ink path, carriage, CR and PF drives, CD/DVD tray, sensors, frames, paper guides, and waste-ink tray.

• Scanner and controls: ADF and touch-panel service for the Artisan 800 family. The Artisan 700 family has separate procedures for its flatbed scanner, button-operated panel, housing, and main board.

• Network and fax: Wired and wireless network fault checks, plus fax logs, error codes, and send, receive, and EXT-port tests for fax-equipped models.

• Post-repair setup: EEPROM data transfer, print alignment, paper-feed correction, platen-gap adjustment, and carriage and paper-feed belt tension checks.

• Maintenance: Printhead cleaning, waste-ink pad replacement and counter reset, and model-specific lubrication points.

Epson wrote the manual for experienced repair technicians and specifies that repairs be performed by Epson-certified technicians.

Operating Principles and Fault Diagnosis

The feature section calls the F6 printhead the F6 Turbo II. The mechanism chapter calls it the F6-Shrink and maps the ink system, decompression motor, paper-feed and eject rollers, photo and CD tray paths, encoders, and sensors.

The Printer Mechanism Block Diagram, Nozzle Layout, Motors & Sensors views, and PG Positions/Cam diagram help connect a symptom to the affected mechanism before the printer is opened. Troubleshooting tables link the symptom and when it occurs to likely parts, connector or mechanical checks, remedies, and the matching disassembly section.

Separate checks address jams, paper-out errors, and double feeding. The fax section explains protocol traces and provides several bench setups for checking a repaired unit.

Teardown and Cable Routing

Disassembly flowcharts cover the housing, scanner, control panel, main board, power supply, wireless LAN board, and card-slot board. A parts-transfer checklist identifies what to move from the old printer when replacing the printer mechanism.

Model-specific flexible flat cable (FFC) routing drawings and the Connector Summary help match cables to their board connectors after board, scanner, motor, or carriage repairs. The manual contains 94 numbered tables and 353 numbered figures. Epson directs technicians to its separate Service Parts Information (SPI) for exploded views and the parts list.

A mispositioned waste-ink tube can leak, and a Transmission Arm left out of the Ink System position can lock the carriage and trigger a fatal error. The scanner procedures flag the risk of damaging the rod lens array or contaminating the timing belt with grease.

Epson’s precautions call for disconnecting AC power before opening the chassis, using ESD protection around the boards, and applying power only when a specified test requires it.

Adjustment Program and Service Tools

The required-adjustment matrix ties each removed or replaced assembly to follow-up work such as counter resets, ink charging, motor compensation, and final check prints. Epson Adjustment Program procedures cover initial settings, MAC address setup, top-margin and bidirectional alignment, PW and first-dot positioning, head-angle and paper-feed adjustments, PG offset, AID and case-open sensor checks, and touch-panel calibration where applicable.

Banding Reduction System (BRS) adjustment and Paper Feed Amount Profile (PFP) correction require a base scale and a supported scanner. The tool list identifies the ink supply tube screwing tool 1508164, PG adjustment tool 1508165, and the Leak Check, Air Release, and Carriage Stopper jigs. Detailed leak-check instructions are in a separate service video. The lubrication drawings specify where to apply each Epson grease.

Belt Tension and Platen-Gap Examples

After removal, reinstallation, or loosening, the timing-belt checks use standard tensions of 12.7 ± 1.84 N for the carriage (CR) belt and 7 ± 1 N for the paper-feed (PF) belt. The PF check specifies the carriage at its home position.

For platen-gap parallelism, each dial-gauge reading must fall within ±0.05 mm. The spread from the highest to the lowest reading must be no greater than 0.05 mm.
