Samsung SCX-6555N Laser Printer Manual Set – 2008 (P/N 6555-N00SEE)

Use the printer service manual for teardown, diagnostics, and parts identification. The accessory manual covers finishing hardware separately, and the training material explains how the printer, firmware, and host software interact during troubleshooting.

The printer teardown chapters apply to the SCX-6555N/SEE. The accessory manual also lists the SCX-6345N, SCX-6545N, CLX-8380ND, CLX-8385ND, and CLX-8540ND as compatible hosts for the finisher and mailbox. The toner-scattering bulletin refers to a separate service video for access to the developer drive.

PDF Search, Bookmarks, and File Contents

Text search and diagram zoom. All 14 PDFs contain searchable text. Some labels in the training diagrams and driver-guide screenshots can only be read on the page. The combined service PDF has bookmarks, with two accessory catalog entries that have no page destination. The training and supplemental PDFs have no embedded bookmarks. Zoom in to read the smaller pin and signal labels on the wiring diagrams.

The ZIP contains 798 pages across 14 printable PDFs. The two service manuals share one PDF, with their covers included. The training manual is a separate PDF. The nested archive contains 12 supplemental PDFs, whose 32 pages include duplicate copies, plus two software utilities.

Printer Teardown, Tech Mode, and Paper-Path Faults

This selection of service topics covers common bench work. Other sections include preventive maintenance parts and service-life counters.

• Printer teardown: Removal and reinstallation of the duplex automatic document feeder (DADF), scanner, operation panel, main board, power boards, fuser, laser scanner unit, and paper drives.
• Tech Mode diagnostics: Fault history, service counters, sensor and actuator tests, engine and DADF routines, fax tests, and network memory initialization.
• Print and scan adjustments: Simplex and duplex registration, scan magnification, DADF speed, and image-density sensor calibration.
• Wiring diagrams: Main-controller, operation-panel, and DADF connector maps, with pin and signal references for power boards and the optional fax board.
• Finishers and feeders: Paper paths, jam removal, stapler service, and fault charts for stacker, mailbox, and high-capacity feeder mechanisms.
• Parts identification: Exploded views and parts lists for the printer and its options, including separate finisher and mailbox catalogs.

For printer service technicians, the paper-path drawings and Tech Mode input tests help distinguish a paper jam from a sensor that fails to register a change.

Print Engine and Replaceable Assemblies

The hardware chapters trace the Orion2 main controller, Hyper3 engine controller, and CIP5 image processor through the scanner, operation panel, SATA drive, network, and optional fax interfaces. The disassembly chapter identifies screw types, cable routes, and color-coded harnesses for the registration, multipurpose, and pickup clutches.

The printer parts catalog covers the frame, drives, fuser, transfer roller, pickup and duplex assemblies, scanner, DADF, and cassettes. The main manual identifies the SCX-FIN11S finisher separately from the SCX-FIN20S covered in the accessory manual. It also identifies the SCX-S6555A second cassette feeder, SCX-HCF100 high-capacity feeder, and SCX-FAX210 serial and SCX-FAX211 parallel fax kits.

Image Quality and Service Checks

The troubleshooting charts address repetitive image defects, paper-feed and DADF jams, scan and fax faults, and laser scanner and fuser errors. Tech Mode provides test patterns, shading and scan-edge checks, copier and fax NVM functions, HDD formatting, and report output. The manual also covers firmware updates.

Technical Training and Field Fixes

The training PDF covers SmarThru Office, Smart Panel, TWAIN and WIA, Network Scan, SetIP, and Direct Printing Utility. Drum and toner cartridge layouts accompany diagnostic flowcharts for lines, light or dark output, background contamination, and toner-supply faults.

Field bulletins address toner scattering, finisher paddle wear, Legal-size stacker detection, and USB printing and scanning lockout on firmware 2.01.01.14. The restoration utility and a Vista 64-bit driver cleanup tool are included. The System Error #02-003 bulletin covers units made before November 2008, where the fuser lever can interfere with the duplex bracket.

Handling Precautions

Light exposure or surface contact can damage the OPC drum. The disassembly notes flag harness routing near moving parts and plastic retaining latches that can break during removal. Disconnect power before opening the printer and follow the manual’s precautions for laser radiation, high voltage, fuser heat, and electrostatic discharge.

Selected Image-Area and Accessory Power Specifications

The SCX-6555N print and copy image-area table specifies margins of 4 mm at the top and bottom and 5 mm at the sides. These margins give technicians a reference for checking apparent edge cutoff.

For electrical checks at the finisher or mailbox, the accessory manual lists printer-supplied input rails of 24 V (±10%), 5 V (±5%), and 3.3 V (±5%).
