2004 Epson Stylus Photo RX700 Printer Service Manual (P/N SEMF05001)

This Epson service manual covers the 2004–2005 Stylus Photo RX700 all-in-one printer, scanner, and copier. Document SEMF05001 is Revision B, issued June 2005.

• Printer mechanisms: Removal and reassembly of the carriage, APG assembly, ASF Drive Assembly, PF and CR motors, and CD-R guide mechanism.

• Ink system: Printhead and Valve Assembly removal, Pressure Pump Assembly service, Ink System Assembly replacement, and waste ink pad replacement.

• Scanner and TPU: Scanner Unit disassembly, CCD carriage and CR Motor Unit removal, TPU Assembly disassembly, and scanner home position calibration.

• Electrical diagnosis: Printer initialization and fatal-error troubleshooting, motor and sensor checks, power-supply fault isolation, and USB and memory-card diagnosis.

• Adjustments and maintenance: Platen gap and PF/FD belt tension adjustments, EEPROM data backup, maintenance counter resets, firmware uploading, and specified lubrication.

• Circuit and parts references: Electrical schematics, connector pin assignments, circuit board component layouts, harness-routing illustrations, exploded views, and the ASP reference list.

Written for experienced repair technicians, this manual calls for Epson-certified personnel familiar with electronics safety.

Carriage, Paper Paths, and Ink Delivery

The operating-principles chapter explains carriage motion, the APG (Auto Platen Gap) transmission, and the F-Mach printhead. Nozzle Arrangement, Ink Path, and Self-closing Valve views show how the off-carriage ink system feeds the head through the cartridge holders, ink tubes, and valve assembly.

Paper-path and gear-train illustrations distinguish front and rear loading from CD-R transport. Reassembly coverage includes CD-R Guide and EJ Frame alignment checks and carriage parallelism.

Pressure-pump service cautions explain how screw access can damage the bellows. The Valve Assembly procedure identifies the Joint Clamp, Spacer, Ink Joints, and Pressure Tube as damage-prone parts requiring replacement after removal.

Electrical and Scanner Fault Isolation

Fatal-error tables connect carriage, paper-feed, APG, head-temperature, and pressure-system errors with component checks. Together with the Printer Power ON flowchart and motor resistance tables, they help distinguish mechanical, wiring, and board faults before selecting replacement parts.

The electrical sections cover C583MAIN, C583PNL, and C583PSB/C583PSE power supplies. Main Board Connector Layout and cable-routing illustrations support removal and installation of the Main Board, Panel Board, and Power Supply Board.

Scanner diagnosis addresses CCD carriage movement, lamp and inverter faults, and unclear images. The Scanner Unit Diagram and ASP reference list relate drawing callouts to component names.

Service precautions address electrical isolation, static-sensitive boards, and ink handling to prevent injury or component damage.

Calibration, Service Software, and Maintenance Counters

The adjustment tables identify which checks follow component removal or replacement. Specified equipment includes sonic tension meter 1231678 and scanner origin adjustment tool 1401646; scanner calibration uses EPSON Scanner Function Test-C583B02W.

Detailed printer-program adjustments are explained in the separate software's help. The manual documents scanner home position adjustment and confirmation, plus firmware uploading from a memory card. Adjustment software and firmware files are not included in this PDF download.

Maintenance coverage distinguishes waste ink counters for the lower case, platen, and cartridge holders from the ink-tube service counter. It links maintenance errors to replacement parts and counter-reset requirements, with separate cleaning and lubrication instructions.

Reference specifications also cover printhead service-life limits, CCD pixel data, cartridge ink weights, and freezing and storage limits.

A Preview of Head Fastening, Gap Adjustment, and Motor Checks

These examples are a small selection of the manual's mechanical adjustment and electrical test data.

The printhead mounting screws have a specified torque of 0.4 ± 0.05 N·m. Platen gap adjustment uses a 1.2 ± 0.1 mm thickness gauge with the mechanism at its minimum PG position and the Valve Assembly installed.

For printer carriage diagnosis, the CR motor resistance specification is 23.6 Ω ± 15% at pins 1 and 2 of its white relay connector.

PDF Search, Bookmarks, and Diagram Detail

Text access and schematic viewing: Body text is searchable, with bookmarks for chapters and subsections; some schematic sheets have searchable titles only. Small component and pin labels require zooming, and the main-board and power-supply drawings use fine, light lines.

One printable English-language PDF download contains 202 pages: 8 pages of front matter, 154 pages across six chapters, and a 40-page appendix. The cover, notices, revision history, and contents are already included in that total.
