Xerox WorkCentre 3210/3220 Printer Service Manual, 2009 (P/N 701P49487)

This Xerox factory service manual covers the WorkCentre 3210 and 3220 Multifunction Printers, P/N 701P49487, first printing March 2009. It goes beyond operator maintenance to cover configuration, theory of operation, fault isolation, and repair of the print engine and attached options.

Searchable Text, Bookmarks, and Wiring Detail

Text access and diagram readability: The PDF has searchable text and embedded bookmarks for chapters and individual service topics. Small connector, pin, and signal labels in the wiring diagrams are best read with zoom.

One printable, English-language 416-page PDF contains 370 chapter pages, 28 preliminary pages, a 6-page reference appendix, an 8-page index, and 4 cover or blank pages. These are all included in the total.

Print Engine, Scanner, and Service Diagnostics

The following selected service topics outline the repair coverage. Other included material covers items such as Power Save settings and configuration-report contents.

• Model differences: Configuration tables distinguish duplex and PostScript 3/SPL support, power configurations, memory expansion, and the optional second paper tray.

• Component diagnostics: Embedded Diagnostic Control tests cover interlocks, paper sensors, the main motor, fans, clutches, fuser control, laser operation, and high-voltage outputs.

• Tech Mode: DRAM, ROM, modem, and scan-shading tests accompany communication settings, service reports, and built-in print patterns.

• Fuser and paper handling: Step-by-step removal procedures cover internal fuser components, feed rollers, registration hardware, duplex components, and the drive unit.

• ADF and scanner service: Illustrated procedures cover the feeder, ADF motor, platen assembly, Contact Image Sensor, timing belt, scan drive, and USB host board.

• Parts and wiring: Exploded assembly views, orderable FRU numbers, component locators, plug/jack maps, and system wiring diagrams support parts identification and electrical fault tracing.

Xerox wrote this manual for authorized service technicians and service partners. It assumes qualified service personnel, strongly recommends product-specific training, and requires Xerox certification to service these models.

Print Engine and Model-Specific Parts

The theory chapter traces media through the ADF, manual feeder, Tray 1, optional Tray 2, registration area, image-transfer stage, fuser, exit path, and duplex unit.

Functional descriptions explain the Contact Image Sensor and scan drive, transfer roller, laser unit, print cartridge and CRUM, drive assembly, main controller, HVPS, switch-mode power supply, sensors, fax line interface, and engine firmware.

Model-specific tables cover print and copy performance, scanning and fax specifications, image area, electrical and environmental requirements, media limits, installation clearances, and maintenance-item life. Expansion information identifies the supported 256 MB DDR2 DIMM and optional 250-sheet Tray 2.

The models use different main controller and UI assemblies, while the fuser parts data distinguish engine-voltage versions. These distinctions matter when selecting replacement parts or applying model-dependent repair information.

Fault Isolation and Print Quality

Control-panel messages and the Error Information Report lead into tables organized by probable cause, initial action, yes/no test branches, applicable parts, and wiring references.

Dedicated procedures address Paper Jam 0/1/2, document and duplex jams, tray/media faults, print-cartridge conditions, fuser thermal errors, laser faults, fax and USB failures, locked motors or fans, door interlocks, and network send/IP conflicts. Separate coverage handles problems without a displayed code, including no power, scanner or ADF malfunction, and computer-interface issues.

The print-quality section connects visible defects with the print cartridge, laser unit, transfer roller, HVPS, fuser, paper path, or ADF. Its repeating-defect chart supports diagnosis of recurring marks; other fault trees address ghosting, lines, bands, uneven density, skew, stains, blank pages, incomplete fusing, and ADF-originated defects.

Eight built-in test patterns support checks for registration, density, ghosting, solid-fill dropout, skew, and text uniformity. Fax troubleshooting also uses the Protocol Report to examine communication exchanges.

Disassembly, Parts, and Repair Notes

Removal procedures provide prerequisite access paths, fastener identification, illustrations, and replacement notes. Fuser coverage extends to the thermistor, thermostat, heat roller, large and small pressure rollers, halogen lamp, exit actuator, and exit sensor.

Paper-feed, xerographic, cover, electrical, drive, and optional-feeder assemblies receive component-level coverage. The wiring chapter includes Circuit Board, Drive, and Sensor locator maps alongside the Power and Fuser, Laser Unit and I/O, and ADF and Scanner diagrams.

Controller replacement: The main controller boards are not interchangeable between models. Replacement notes address DIMM transfer, and Tech Mode instructions require clearing memory after controller replacement; that reset erases customer settings.

Fuser handling: Oil transferred from fingers can damage the halogen lamp, and excess force can break a lamp cap. Replacement notes also identify the correct heat-roller bushing positions.

Fuser and power-supply work involves hot parts and hazardous voltage, so the manual's power-isolation and cool-down precautions must be followed before internal service.

Cleaning, Adjustments, and Firmware

Cleaning procedures cover the print-cartridge area, laser-unit window, document glass, rollers, and the Clean Drum page. The dedicated adjustment chapter is limited to altitude compensation; scan-quality shading is handled through Tech Mode.

Firmware-update procedures cover the USB utility and network updating through CentreWare IS.

Selected Roller and Electrical Diagnostic Values

The repeating-defect reference lists a 75.5 mm OPC drum circumference and a 26.7 mm charge-roller circumference for the print cartridge. The chart associates these components with different recurring spot and band patterns.

For electrical troubleshooting, the general measurement table gives +4.75 to +5.25 VDC for a nominal +5.0 VDC reading unless a procedure specifies otherwise. Component-specific troubleshooting tables supply the relevant test locations and conditions.
