Epson Stylus Pro GS6000 Printer Service Manual – 2008 (P/N SEIJ08001)

The Epson Stylus Pro GS6000 Service Manual, P/N SEIJ08001, Revision B (December 12, 2008), covers maintenance, fault diagnosis, component replacement, and post-repair adjustment for this large-format Eco-Solvent inkjet printer.

PDF Search, Bookmarks, and Diagram Detail

Text search and diagram labels: The main text is searchable, although some illustration labels do not search correctly. Embedded bookmarks navigate the chapters and many subsections. Small connector labels in the Block Wiring Diagram require zooming.

The download contains one printable English PDF with 285 pages, including seven preliminary pages covering the original cover, precautions, manual introduction, revision history, and contents. The total also includes 31 exploded-diagram sheets.

Ink-System, Carriage, and Heater Service

These selected coverage highlights outline the repair content rather than reproduce the complete contents. Other topics include job-information printouts and Bonjour network settings.

• Ink-system repair: Step-by-step replacement procedures for printheads, head valves, caps, maintenance assemblies, flushing boxes, cleaner heads, wipers, pumps, two-way valves, sub tanks, and left/right ink tubes.

• Carriage, feed, and take-up work: CR and PF motors, drive and reduction belts, encoder scales, carriage-lock solenoid, pressure rollers, and Auto Take-Up Reel Unit disassembly and reassembly.

• Electrical and heater service: Main, power-supply, heater-control, heater-relay, LVDS, C679PROG, and Sub-A/B/C/D boards, with connector assignments and procedures for heaters, thermistors, fans, and sensors.

• Fault isolation: LCD messages, maintenance requests, service-call codes, and print-quality troubleshooting for drive, encoder, ink-system, heater, power, and communication faults.

• Post-repair adjustment: NVRAM backup/restore, belt tension, carriage height, head-rank input, head slant, nozzle alignment, Uni-D/Bi-D low-gap timing, paper feed, and life-counter resets.

• Maintenance procedures: Setup and transportation, waste-ink handling, wiper and printhead-area cleaning, pressure-roller and platen cleaning, CR-rail care, and component-specific lubrication.

• Factory reference material: Disassembly flowcharts, Block Wiring Diagram, panel menu maps, parts list, and exploded diagrams, supported by operating-principle illustrations and board connector layouts.

Written for experienced repair technicians, the manual assumes mechanical and electrical service skills and access to the specified tools and software. Epson's safety notice specifies Epson-certified personnel for repair work.

Diagnostics Beyond Error Codes

The troubleshooting tables separate ordinary panel messages from service-call errors and print-quality symptoms. Dot loss, front- or back-side ink smear, and horizontal or vertical banding are linked to ink-path faults, vacuum fans, heater operation, CR/PF encoder feedback, media feed, and head-adjustment checks.

Serviceman Mode provides error history and individual checks for cover, lever, sub-tank, waste-fluid, paper-edge, and home-position sensors. Tests also cover encoders, fans, heaters, solenoids, the wiper, control panel, and alarm LED. RTC/NVRAM faults and printhead errors have their own diagnostic entries.

Panel coverage explains custom paper records, MicroWeave choices, paper-feed and head-alignment settings, heater control, paper suction, drying time, carriage movement, and multiple-layer printing.

Repair Planning and Adjustment Requirements

The adjustment matrix links each repaired or replaced component to the required tests, calibrations, and counter resets in their specified order. Main-board replacement requirements differ depending on whether the original NVRAM data can be backed up, allowing technicians to identify the appropriate restoration or setup work before replacing the board.

The manual documents the Epson Service Program and NV-RAM Backup Utility, media side-margin calibration, RTC and USB ID settings, and firmware updates. These software applications are not included in the PDF.

The two-printhead system uses eight 180-nozzle rows per head, supplied through sub tanks. Printhead replacement includes the associated head-valve assemblies and head-specific alignment requirements. The take-up section separately covers its sensors, control board, power board, switch, motor, and chain-tension setup.

Operating-principle views include Ink System, Carriage Mechanism, Paper Feed Mechanism, and Heater Mechanism, with further illustrations identifying boards and sensors.

Service Tools and Repair Cautions

Specified fixtures include GS6K Tube Holder 1501560, Spring Set Tool 1501561, Head Holder 1501562, PG Adjustment Jig 1501563, and Belt Tension Attachment 1501564. Adjustment requirements also identify Marking Film 1502538, push-pull gauges, and ThreeBond 1401 thread locker.

Maintenance references identify kit C12C890611, Ink Cleaner C12C890621, and approved lubricant part numbers 1506789 and 1432563, with application points shown for the serviced mechanisms.

The printer, heaters, and take-up reel have separate power feeds; the manual requires the applicable cords to be unplugged before disassembly and specifies ESD protection for board handling.

A diagonally inserted FFC can short board electronics, while water, contaminated cleaning sticks, or bare-finger contact around the cleaner head can damage the printheads. Factory-set platen and rear-guide parallelism screws must remain undisturbed; frame disassembly is prohibited because these structures are precisely aligned at the factory.

Examples of Belt-Tension and Skew Specifications

The CR belt procedure specifies a 100–110 g push-pull gauge reading with the belt brought into contact with the frame. The CR reduction-belt adjustment specifies a 3.5 kg ±10% pull on the adjustment wire.

The skew test specifies a limit of ±0.5 mm for a 1.0 m feed test using 1250 mm marking film.
