It is designed for repair service personnel, providing detailed information necessary for proper maintenance and servicing. The manual covers various models, including the WorkForce 635 series (WorkForce 635, Epson Stylus Office TX620FWD, Epson Stylus Office BX625FWD, Epson ME OFFICE 960FWD, WorkForce 633, WorkForce 630, Epson Stylus SX620FW, WorkForce 645, Epson Stylus Office BX635FWD, WorkForce 545, Epson Stylus Office BX630FW, Epson ME OFFICE 940FW), WorkForce 625 series (WorkForce 625, Epson Stylus NX625, TX560WD, SX525WD, Epson Stylus Office BX525WD, Epson ME OFFICE 900WD, Epson Stylus NX530, SX535WD, NX635, Epson Stylus Office BX535WD), and WorkForce 60 series (WorkForce 60, T42WD, Epson Stylus Office B42WD, Epson ME OFFICE 82WD, Epson ME OFFICE 85ND).

The manual is structured into four main chapters: Disassembly/Reassembly, Adjustment, Maintenance, and Appendix. Each chapter addresses specific aspects of device servicing.

Function Description

The devices covered by this manual are color inkjet printers, designed for various office and home office tasks. They are capable of printing, and many models include additional functionalities such as scanning, copying, and faxing, indicated by terms like "FWD" (Fax, Wireless, Duplex) and "FW" (Fax, Wireless). These printers utilize an ink system with multiple cartridges to produce color prints. The internal mechanism involves components like a printhead, CR (Carriage) and PF (Paper Feed) scales, various rollers, gears, and sensors to accurately move paper and the printhead during operation. The devices are equipped with a panel unit, which may include an LCD for user interaction and control. Some models feature an Automatic Document Feeder (ADF) for efficient scanning and copying of multiple pages, and a duplex unit for double-sided printing. Connectivity options often include USB and wireless LAN modules, allowing for flexible integration into different network environments.

Usage Features

The printers are designed for ease of use, with a focus on efficient document handling. The panel unit, often with an LCD, provides an intuitive interface for navigating menus, checking status, and initiating tasks. Features like the ADF simplify the process of scanning or copying multi-page documents, reducing manual effort. Duplex printing capabilities help save paper and reduce environmental impact. The ink system is designed for user-friendly replacement of ink cartridges. The overall design aims for reliable performance in a typical office or home office setting, supporting various printing needs from text documents to color graphics.

Maintenance Features

The manual provides detailed guidance for maintaining the printer's optimal performance and extending its lifespan.

Disassembly/Reassembly: This section outlines the procedures for disassembling and reassembling the main parts and units of the product. It includes flowcharts to guide technicians through the process, indicating which parts are supplied as After Service Parts (ASPs) and providing standard operation times for various tasks. Specific instructions are given for handling sensitive components like the printhead, CR scale, PF scale, and various FFCs (Flexible Flat Cables) and cables. The importance of using recommended tools and observing specified torque when tightening screws is emphasized to prevent damage. Special attention is paid to the routing of FFCs and cables to ensure proper reassembly and functionality.

Adjustment: This chapter details the necessary adjustments required during servicing. This includes procedures like PF Timing Belt Tension Measurement, PF Belt Step Check, and checking the Platen Gap. These adjustments are crucial for maintaining print quality and ensuring the precise movement of internal mechanisms. The manual also covers MAC Address Setting, which is relevant for network-enabled printers.

Lubrication: A dedicated section on lubrication specifies the points within the printer that require lubrication and provides instructions on the type and amount of grease to be applied. Proper lubrication is essential for the smooth operation of moving parts, such as gears, rollers, and the CR assembly, preventing wear and tear and ensuring longevity.

Cleaning: The manual describes cleaning procedures for various parts of the printer. Regular cleaning helps prevent issues caused by dust, ink buildup, or other contaminants, which can affect print quality and the overall performance of the device.

Safety Precautions: Throughout the manual, safety precautions are highlighted using specific symbols. These include warnings about disconnecting power, wearing protective goggles, avoiding flammable compressed air products, and handling ink safely. Technicians are advised to be certified by Epson and to use only Epson-approved replacement components to maintain product integrity and warranty. The manual also stresses the importance of using anti-static wrist straps when handling internal electronic components to prevent damage from static discharge.

Troubleshooting: The Appendix includes information for troubleshooting common issues, such as power-on sequences, connector diagrams, and fatal error codes. This helps technicians diagnose problems efficiently and apply appropriate solutions.

The manual also includes a revision status, documenting changes and updates to the service procedures and supported models over time, ensuring that technicians have access to the most current information.
