2007 Toshiba e-Studio 166 / 206 Service Manual (P/N SME060035A0)

This 65-file PDF documentation set covers Toshiba e-STUDIO166 and e-STUDIO206 mechanical service, diagnostics, circuit-level troubleshooting, parts identification, operation, software support, and Toshiba technical field updates. Its core publications include both 238-page service-manual revisions—P/N SME060035A0, Ver01_2007-03 and P/N SME060035B0, Ver02_2008-06—along with the later Service Handbook. Most service-manual content is shared between the two revisions; the B0 version adds revised CIS flat-harness routing and installation notes.

• 1,633 PDF pages across 65 files — 476 pages of e-STUDIO166/206 service manuals; 244 pages of Service Handbook material; 162 pages of PC-board circuit documentation; 94 pages of parts data; 508 pages of operator and TOSHIBA Viewer documentation; 4 setup pages; and 145 pages of technical bulletins.
• Regional and option coverage includes NAD, ASD, AUD, MJD, ASU, SAD, ARD, CND, TWD, KRD, and JPD machine versions, with references for the KA-1640PC/C platen cover, MR-2017/C ADF, MY-1027/C paper feed unit, GC-1240/C expansion memory, KK-1660/C manual pocket, MF-1640U/E damp heater, and MH-1640 desk.
• Mechanical repair sections address cover and PC-board replacement, scanner and CIS hardware, laser optical-unit replacement, main and toner drives, drawer and bypass feeding, registration components, the process unit, drum cleaner and chargers, developer unit, fuser/exit unit, power supply, and option removal and installation.
• Diagnostic and adjustment material covers jam and service-call codes, input/output checks, test-print and list-print modes, Adjustment Mode 05, Setting Mode 08, image-dimension and image-quality correction, high-voltage adjustment, scanner-belt setup, paper-feed alignment, developer adjustment, and MR-2017 ADF alignment.
• Electrical references include system block diagrams, component and harness layouts, scanner-motor and CIS circuits, MAIN-board image processing, laser and polygon-motor control, main-motor and high-voltage circuits, fuser control, power-supply sequencing, and AC/DC harness drawings.
• Board-level documentation supplies ASIC pin and signal descriptions plus circuit drawings for the e-STUDIO166/206 MAIN board, SRAM, LDR laser drive, SNS H-sync detection, FUS, and LPNL control-panel boards.
• Parts, PM, and tooling coverage combines exploded assembly views with service-parts tables, PM kits, replacement and cleaning checklists, grease specifications, and dedicated jigs for developer, scanner-belt, high-voltage, ADF, and firmware work.
• Field and operator support adds 54 bulletin PDFs, region-specific copying manuals, the TOSHIBA Viewer manual, and a multilingual unpacking/setup sheet. The bulletins document production changes, revised repair procedures, part interchangeability, and field countermeasures issued from 2006 through March 2009.

Service and Repair Coverage

The service manuals follow the operating path from original scanning and image processing through laser exposure, drum charging, development, transfer, fusing, and paper exit. Functional chapters explain initialization and warming-up, drawer and bypass feed sequences, control-panel states, abnormality detection, and power-supply behavior. Illustrated repair sections identify the covers, connectors, sensors, clutches, solenoids, rollers, boards, and assemblies involved in removal and replacement work.

The 235-page e-STUDIO163/166/203/206 Service Handbook, P/N SHE050005M0, Ver13_2009-01, contains much of the diagnostic information cross-referenced by the service manuals. It includes jam and service-call lists, Test Modes 03 and 04, test-print and list-print functions, country/region codes, 05/08 service data, image troubleshooting, MAIN/SRAM replacement requirements, preventive-maintenance checklists, PM kits, and firmware updating.

Adjustment coverage extends to auto-toner sensing, registration and image dimensions, copy/print/scan density and sharpness, high-voltage output, CIS and scanner-drive belts, paper sideways deviation, developer doctor-to-sleeve gap, and MR-2017 ADF position, height, skew, leading edge, horizontal position, copy ratio, and opening/closing sensor setup.

Firmware repair support covers the system and ADF through dedicated download jigs and the USB Software Update Tool. The older TOSHIBA Viewer firmware subsection applies only to e-STUDIO163/203, while the Software Update Tool section covers e-STUDIO163/166/203/206. This model distinction is important when choosing an update method for an e-STUDIO166 or 206.

Schematics, Parts Identification, and Field Updates

Representative electrical references include the e-STUDIO166/206 system block diagram, scanner-motor drive and CIS exposure/CCD circuits, MAIN-board image-processing configuration, laser-diode and polygon-motor control, high-voltage and fuser-control circuits, and AC/DC wire-harness connection drawings.

The separate 162-page PC Board Repair Manual, P/N RME050003A0, extends the coverage to board-level signal tracing. It contains ASIC references and schematics for the e-STUDIO166/206 MAIN board, SRAM, LDR, SNS, FUS, and LPNL boards, together with shared-family and option-board circuits. This publication supports electronic diagnosis but does not replace the mechanical removal, adjustment, and safety procedures in the service manuals and handbook.

The 94-page parts PDF combines an e-STUDIO166/206 differences package with the underlying e-STUDIO163/203 parts catalog, File No. PLE050045000. The difference sheets must be used with the base exploded views and service-parts tables when identifying 166/206 components. Illustrated groups cover the exterior panels and frames, control panel, optical frame and drive, main drive, bypass and registration sections, platen and charger assemblies, cleaner, developer and recycle path, fuser, drawer, service jigs, supplies, replacement units, and PM kits. Regional entries distinguish parts such as MAIN boards, laser units, supplies, and fuser units.

The bulletin collection adds repair information released after the original 2007 service manual. Subjects include revised CIS installation, corrected SRAM-board replacement, developer-sleeve noise, multiple drawer feeding, solid-black/C97 faults, fuser-harness trapping, ADF closure, heater-lamp and thermostat fasteners, power-supply changes, and harness updates. Many bulletins identify before/after part numbers, interchangeability, and production or serial-number application points.

Tools and Repair Notes

Dedicated service tools are identified by part number, including doctor-sleeve jig P/N 4402048100, scanner belt-tension jig P/N 6LE60640000, high-voltage measurement jig P/N 6LA91605000, ADF download jig P/N 44205829000, and system download jigs P/N 6LA41994000 / 6LA41995000.

The laser optical unit is sealed, finely adjusted, and sensitive to contamination; the manual treats it as a replacement assembly and warns against field disassembly. For scanner and MAIN-board repair, the B0 revision requires the CIS flat harness to pass through its holder without warping, while the MAIN flat harness must face the specified electrode direction or a CA2 fault can result. Fuser repair requires correct identification and positioning of the center and side heater lamps and careful pressure-roller handling to prevent deformation; incorrect handling of the drum separation fingers can also scratch the drum.

Several publications in the set share material with e-STUDIO163/165/167/203/205/207/237 models or related options. Model headings, regional codes, and bulletin applicability should therefore be checked before using a circuit, part number, firmware method, or field countermeasure on an e-STUDIO166/206. The US copying manual is specific to the e-STUDIO166, while the EU and Other Locations manuals cover both 166 and 206. The Viewer documentation reflects the Windows 2000/XP software environment and covers USB drivers, printer setup, local and network printing, scanning, email functions, TOSHIBA Viewer, and GDI printing.

Service work can expose the technician to retained high voltage, hot fuser components, moving drives, laser radiation, and ESD-sensitive boards. Disconnect main power for mechanical repair unless a specified live test is required, follow the publication’s isolation and wrist-strap precautions, and restore all interlocks, covers, and safety devices before operational testing.
