2006 Xerox Phaser 8560MFP Service Manual (P/N 705P01133)

• A 296-page PDF of Xerox service documentation covering Phaser 8510MFP/N, 8510MFP/D, 8560MFP/D, 8560MFP/T, and 8560MFP/X multifunction configurations.
• Print-engine repair procedures cover removal and replacement of the Printhead, Ink Loader, Drum Assembly, and Purge Pressure Pump, with component-specific installation checks.
• Mechanical service extends to the Transfix Roller, transfix and drum-maintenance camshafts, and Drum Maintenance Pivot Plate. Dedicated adjustments cover Process Drive alignment, Wiper Blade alignment, and Head Tilt Gear/Printhead homing.
• Scanner and Duplex Automatic Document Feeder (DADF) replacement procedures are paired with DADF-to-scanner calibration for grayscale response and front-to-back image alignment.
• Paper-path repair coverage includes pick and retard rollers, the Preheater and Deskew Assembly, duplex transport components, and the Exit Module’s roller and elevator drives.
• Control Panel diagnostics support motor, clutch, solenoid, sensor, and heater testing. Startup troubleshooting covers Built-in Self Tests (BIST), Power On Self Tests (POST), and Print Engine Self Tests (PEST), with LED blink-code interpretation.

Model and Option Coverage

This is the October 2006 service documentation, carrying a November 1, 2006 reissue notation. The configuration tables distinguish the 8510MFP’s Flash Disk from the 8560MFP’s Hard Drive and identify differences in duplex operation, optional feeders, and advanced copy/fax features. Memory specifications cover expansion up to 1 GB.

PagePack metered operation is explained separately, and the parts list distinguishes metered and non-metered Ink Loaders. The optional Foreign Device Interface has its own replacement procedure.

Service and Troubleshooting Overview

The Image Quality section provides structured procedures to identify print-quality defects like streaks, voids, and misaligned output. Separate diagnostic paths distinguish print-engine faults from scanner and DADF problems. Ghosting, oil streaks, incomplete image transfer, and first-side duplex smears receive dedicated treatment. Service test-print analysis and Jet Substitution Mode address weak or missing jets and the limits of compensating for them.

Fault-code procedures connect symptoms to applicable parts, wiring references, and diagnostic tests. Coverage reaches the printhead jetstack and reservoir thermal sensors, ink-melt heaters, and drive assemblies rather than stopping at code definitions. Engine Error History, Jam History, and the Service Usage Profile support fault isolation; a power-on sequence chart helps locate startup failures.

Check Menu descriptions extend to Y-axis encoder, belt-slip, and belt-tension tests, paper-edge timing, and transfix-gap checks. Program-fault and jam-code coverage concentrates on commonly encountered conditions, not every possible code combination.

Network and USB port verification accompany fax-modem tests and interpretation of Fax Transmission and Protocol Reports. Serial Back Channel Trace capture is documented for difficult faults, specifying null-modem cable P/N 012153500 and diagnostic serial adapter P/N 012154300. The computer-side procedures reflect Windows XP and Mac OS X environments of this edition.

Electrical Repair and Reassembly Details

Separate replacement procedures cover the Wave Amplifier, I/O Board, Scanner Power Supply, and Drum Heater Relay Board. Electronics Module service is assembly-level, rather than component-level repair of its internal boards. Replacement instructions address retaining the machine’s RAM, NVRAM, Configuration Card, and storage device.

The reassembly cautions explain how incorrect homing can damage the Process Drive during initialization. The Wave Amplifier procedure also warns that improperly connected ribbon cables can damage the amplifier.

Theory of Operation explains how drum oiling, printhead movement, pressure purging, and transfix loading interact during imaging. These relationships matter when a symptom involves more than one drive or maintenance assembly.

Wiring, Specifications, and Service Tools

Wiring diagrams are paired with plug/jack location maps and harness-routing views. The Scanner/DADF Block Diagram follows the image-input electronics, while Electronics Module Power identifies power connections. Right Side Harness / I/O Control covers engine-drive connections, and Exit Module Control Board details output-transport connections. For mechanical reassembly, Process Drive Gear Alignment shows the gear-position references.

Illustrated parts lists connect assembly callouts with part numbers and service kits. Specification categories include print-engine and scanner performance, media limits, image skew and margins, electrical test values, and component-specific tightening torques. The service-tool list identifies torque screwdriver P/N 003082700.

Many Check Menu tables contain N/A entries for typical values in this edition. The diagnostic section explains test behavior and returned results, but does not provide numerical acceptance limits for every test.

Internal service procedures are written for product-trained technicians. Working on high-voltage and thermal printer systems carries inherent risks. Follow the manual’s safety procedures, including power isolation and printhead cooling, before physical repair work.
