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

• Covers the Xerox WorkCentre 3210 and 3220 Multifunction Printers in a 416-page PDF; official Xerox Part #701P49487, first printing March 2009.
• Separates the two configurations, including the 3220-only standard duplex unit and PostScript 3/SPL support, model-specific power configurations, memory expansion, and the optional second paper tray.
• Decodes the serial-number format and six-digit sequence ranges: UAG 536501-558500, UAH 426501-470500, UAK 492501-536500, and UAL 470501-492500.
• Uses Embedded Diagnostic Control and Tech Mode tests to check cover and paper sensors, the main motor, fans, clutches, fuser control, laser operation, high-voltage outputs, DRAM/ROM, modem operation, and scan shading.
• Provides removal and replacement coverage for the fuser and its internal parts, ADF and scanner assemblies, paper-feed and duplex hardware, drive unit, controller and power boards, fans, DIMM, and optional tray.
• Includes exploded parts views with orderable FRU numbers, plug/jack locators, and the Circuit Board, Drive, Sensor, Power and Fuser, Laser Unit and I/O, and ADF and Scanner diagrams.

This factory service literature goes well beyond operator maintenance. It covers configuration, theory of operation, fault isolation, and repair of the print engine and attached options. Xerox identifies authorized service technicians and service partners as the intended users, assumes qualified service personnel, strongly recommends product-specific training, and states that certification is required. 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.

Print Engine, Scanner, and Configuration Coverage

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. Separate functional descriptions cover 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 specification tables cover processor and memory configuration, print and copy speed, scanning and fax performance, image area, electrical and environmental requirements, media and tray limits, clearances, and maintenance-item life. The serial reference maps UAG and UAH to the 110 V and 220 V WorkCentre 3210 engines, respectively, and UAK and UAL to the corresponding WorkCentre 3220 engines. It also records the soldered 128 MB base memory, the supported 256 MB DDR2 DIMM and 384 MB maximum, and the optional 250-sheet Tray 2.

The 3210 and 3220 use different main controller and UI assemblies, while the fuser parts data distinguish 110 V and 220 V versions. These distinctions matter when selecting replacement parts or applying model-dependent repair information.

Diagnostics and Image-Quality Fault Isolation

Control-panel messages and the Error Information Report lead into troubleshooting 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, a locked main motor or fan, door-interlock problems, and network send/IP conflicts. Problems without a displayed code are covered separately, including no power, scanner or ADF malfunction, fax line faults, and computer-interface issues.

The print-quality section links visible defects to the print cartridge, laser unit, transfer roller, HVPS, fuser, paper path, or ADF. It includes a repeating-defect chart based on roller intervals, along with fault trees for ghosting, lines and bands, uneven density, skew, stains, blank pages, incomplete fusing, and ADF-originated marks. Eight built-in test patterns support checks for registration, density, ghosting, solid-fill dropout, skew, and text uniformity. The dedicated adjustment chapter is limited to altitude compensation; scan-quality shading is handled through Tech Mode. Firmware-update procedures cover both USB and network methods.

Disassembly, Parts, and Repair Notes

The disassembly chapter supplies prerequisite removal paths, fastener identification, illustrations, and replacement notes for field-replaceable assemblies. Fuser work extends past complete-unit replacement to the thermistor, thermostat, heat roller, large and small pressure rollers, halogen lamp, exit actuator, and exit sensor. Document-handling coverage reaches the ADF motor and feeder, platen assembly, Contact Image Sensor, timing belt, scan drive, and USB host board. Paper-feed, xerographic, electrical, cover, drive, and optional-feeder procedures are documented at comparable component level.

Several model-specific cautions help prevent costly repair mistakes. The WorkCentre 3210 and 3220 main controller boards are not interchangeable. The replacement notes call for transferring the DIMM, and the Tech Mode section requires clearing memory after a controller-board replacement so the system operates correctly. During fuser teardown, oil transferred by handling can damage the halogen lamp, excess force can break the lamp cap, and the heat-roller bushings must return to their correct positions.
