Description

This OEM Xerox CopyCentre C118 / WorkCentre M118 Service Manual is the controlling publication for every service call on these machines. It is designed for certified, product-trained technicians and provides complete procedures to diagnose faults, adjust components and keep the device in top operating condition.

1. Manual Overview & Introduction

• Product covered: CopyCentre C118, WorkCentre M118

• Document type: Service Documentation (Part No. 701P23530, initial issue December 2004)

  75709737-Work-Centre-M118-Servi…

• Explains how to use the documentation set, service strategies and call flow

• Detailed symbology & nomenclature for RAPs, BSDs, wirenets and signals

• Extensive ESD and laser safety guidance, warning / caution conventions, and translated safety notes for multi-language technicians

2. Section Structure (from Bookmarks / TOC)

The manual is organized into eight major sections:

1. Service Call Procedures

2. Status Indicator RAPs (fault code diagnostics)

3. Image Quality

4. Repairs / Adjustments

5. Parts Lists

6. General Procedures & Diagnostic Information

7. Wiring Data & Block Schematic Diagrams

8. Accessories (Fax kit, foreign interface, extra trays, DADF/ADF, etc.)

Each section contains step-by-step service procedures with references to wiring diagrams, BSD chains and plug / jack locations.

3. Service Call Procedures & Maintenance

The Service Call Procedures section defines the full workflow for every visit:

• Initial Actions – questioning the operator, checking power and cables, viewing jam history and error histories, entering diagnostics and printing CE reports.

• Call Flow charts – decision trees for UI faults, jams, noise, network issues, copy vs print vs fax problems and remote fax diagnostics.

• Detailed Maintenance (HFSI) – high-frequency service items with thresholds and required actions (feed rolls, retard pads, BTR, fuser, MPT rolls, IIT rollers, etc.).

• Cleaning Procedures – standard cleaning points (feed components, toner dispense, jam sensors, scanner optics, DADF/ADF paths and platen glass).

• Final Actions – test prints, CE report, customer demo and network reconnection workflow.

4. Status Indicator RAPs & Fax Error Codes

A large portion of the manual is dedicated to Status Indicator Repair Analysis Procedures (RAPs) covering:

• C-codes – paper path and tray feed jams (Tray 1–4, duplex, MPT, registration sensor).

• E-codes – fuser exit sensor timing and static jams.

• H-codes – tray lift failures, cassette size errors, NVM and communication errors.

• J-codes – toner and developer CRUM issues, ATC sensor faults, cartridge life.

• S-codes – ADF/DADF document feed and scan jams, static jams, cover-open conditions.

• U-codes – main motor, ROS, fuser, dispense motor and memory/NVM failures.

• Z-codes & Fax error codes – billing counter faults plus dozens of fax protocol and modem-related errors, with step-by-step RAPs for each.

Each RAP includes:

• Initial actions and relevant BSD references

• Input/output checks via diagnostics

• Wiring checks, voltage checks and resistance values

• Clear pass/fail criteria and replacement steps (sensor, motor, clutch, PWB, harness etc.)

5. Image Quality & Adjustments

The Image Quality section provides:

75709737-Work-Centre-M118-Servi…

• Entry RAP for IQ troubleshooting (copy/print separation, IQ vs hardware faults)

• Image quality specifications and defect samples

• Targeted procedures for density, background, voids, lines, registration, skew and duplex image shift

• Separate handling of Platen vs DADF/DADF alignment with adjustment procedures in the Repairs/Adjustments chapter

6. Repairs / Adjustments (Mechanical & Electrical)

Section 4 contains full removal, replacement and adjustment procedures for all major subsystems:

75709737-Work-Centre-M118-Servi…

• Drives – main drive assembly and associated gearing

• Paper transport – feed / retard / nudger rolls, registration units, left chute, exit & OCT assemblies, MPT unit and retard pads

• Xerographics & development – XERO/developer cartridge, toner cartridge, dispense motor, bias transfer roll

• Fuser – complete fuser assembly R&R and related safety cautions

• Electrical – MCU PWB, ESS PWB, STM/2TM PWBs, NBCR, image inverter, control PWBs

• IIT / scanner – control panel, carriage, exposure lamp, mirrors, carriage cables and PWB box

• Feeders & trays – 2-tray and 4-tray modules, DADF/ADF, rollers and retard components

• Covers & cosmetic parts

Each procedure lists necessary tools, safety warnings, disassembly order, re-assembly notes and any required post-replacement adjustments.

7. General Procedures, Wiring Data & BSDs

Sections 6 and 7 give the deeper technical backbone of the machine:

75709737-Work-Centre-M118-Servi…

• General diagnostic programs and copier/printer information (CE settings, counters, protocol traces, test prints).

• Wirenets & power distribution diagrams with plug/jack location tables.

• Block Schematic Diagrams (BSDs) showing functional relationships between sensors, actuators, motors, PWBs, operator actions and paper path.

• DC and logic level voltage specs, logic high/low thresholds, measurement conventions and example test-point references for use with a DMM.

These sections are critical when tracing complex power or signal problems beyond simple part swaps.

8. Accessories & Options

The Accessories chapter includes installation and service information for:

• Fax kit

• Foreign interface (e.g., external accounting or control)

• Additional tray modules (2T, ST)

• DADF/ADF units and document trays

It also repeats key safety warnings (power-off, unplug) for each accessory procedure.

9. Safety, ESD & Laser Precautions

Throughout the manual you get clearly highlighted Warnings, Cautions and Notes plus:

• Laser hazard information (Class 3B during servicing) and interlock rules

• ESD field service kit usage and handling rules for PWBs

• Hot surface, shock hazard and ESD icons explained

At the end of the day, this PDF gives you everything a dealer tech has: fault-code RAPs, alignment and IQ procedures, wiring and BSDs, and precise part-level repairs.
If you service the C118 / M118 even occasionally, this single manual can turn multi-visit guesswork into one efficient, billable call.
