HP LaserJet P3010 Series Printers Service Manual (P/N CE524-90909)

This 342-page HP OEM service manual covers the HP LaserJet P3010 Series, including the P3015, P3015d, P3015n, P3015dn, and P3015x configurations. It is an HP publication, Edition 1 (July 2009), with P/N CE524-90909 printed on the copyright and back pages. Supplied in PDF format, the manual is written for repair work rather than routine operator use, combining factory theory, FRU removal and replacement, diagnostics, error-code troubleshooting, parts identification, and electrical documentation.

• Factory diagnostics: engine-test pages, fuser test page, paper-path test, automatic and interactive sensor tests, component tests, half self-test, drum-rotation check, event-log diagnostics, NVRAM initialization, cold reset, and firmware/service-mode functions
• Model-specific coverage: automatic duplex functions apply to the d, dn, and x models; the P3015 base model does not support automatic two-sided printing, and the manual covers the Tray 3/Tray 4 500-sheet feeder system
• Major repair procedures: formatter PCA, transfer roller, fuser, registration assembly, duplex media-feed assembly, laser/scanner, engine control unit (ECU), high-voltage power supply, fuser motor, main and sub fans, environmental sensor, and Tray 1/Tray 2 pickup solenoids
• Voltage- and configuration-specific parts data: 110 V and 220 V fusers and engine-controller PCAs are identified separately, along with different HVPS assemblies for simplex and duplex machines

The diagnostic section is built around isolating paper-path and image defects before assemblies are replaced. The programmable print/stop test ranges from 0 to 60,000 ms. HP gives known sheet positions at specific stop times—for example, 500 ms stops the leading edge before it enters the fuser nip, while a 3,000 ms duplex stop places the leading edge about 15 mm past the duplex media-feed sensor (PS502). Interactive sensor testing covers the A–Q paper-path designators, including the TOP sensor (PS215), fuser delivery sensor (PS2), duplex media-feed sensor (PS502), media-width sensor (PS225), tray feed sensors, cassette-presence switches, and door sensors.

For repeating image defects, the manual provides a measurement ruler that ties defect spacing directly to likely rotating components: 38 mm for the primary charging roller, 43.6 mm for the transfer roller, 50 mm for the developing roller, 76 mm for the fuser film, 79 mm for the fuser pressure roller, and 95 mm for the cartridge OPC. This gives a technician a repeatable way to narrow a repair before replacing assemblies.

Component and System Documentation

The theory section breaks the printer into the engine-control, laser/scanner, image-formation, media-feed, and option systems. It explains DC-controller coordination, formatter operation, the low- and high-voltage power supplies, the electrophotographic process, toner-cartridge memory-tag communication, jam detection, and the separate paper-feeder electronics used by Tray 3 and Tray 4.

Fuser coverage goes beyond removal. The manual identifies heater H1, main and sub thermistors TH1/TH2, thermoswitch TP1, the fuser-heater control and safety circuits, and the conditions used for start-up, low-temperature, high-temperature, and zero-crossing failure detection. The low-voltage supply documentation identifies +3.3 V, +5 V, and +24 V rails, while the HVPS section maps the charging, developing, transfer, and fuser-film biases.

Assembly Maintenance and Technical Data

Factory removal and replacement procedures cover repairs that commonly require substantial teardown, including complete laser/scanner replacement, ECU replacement, HVPS replacement, fuser and registration work, and duplex media-feed service. The parts chapter adds exploded assemblies with service part numbers. Examples include 110 V/220 V fusers RM1-6274-000CN and RM1-6319-000CN, engine-controller PCAs RM1-6281-000CN and RM1-6318-000CN, and simplex/duplex HVPS assemblies RM1-6300-000CN and RM1-6280-000CN. The listed maintenance kits are CE525-67901 for 110 V and CE525-67902 for 220 V units.

For electrical and mechanical tracing, named drawings include the Product cross section, Fuser control circuit, Pickup, feed, and delivery block diagram, ECU controller connections, General timing chart, and two-part General circuit diagram. Connector locations and harness identifiers are documented throughout; the formatter removal sequence identifies J14, J17, J16, and FFC J18, while the ECU map ties connectors to motors, fans, sensors, solenoids, fuser circuits, and the formatter.

There are several repair details worth knowing before teardown. The cartridge door must be closed before extracting the fuser or the fuser can be damaged. During HVPS removal, HP specifically warns against removing the gear cover because the gears behind it are not captive and can be dislodged. Flat flexible cables must not be bent or folded and must be fully seated; an incorrectly seated FFC can short a PCA, and the laser/scanner FFC can produce a 51.1 error if it is not reconnected correctly.

One important scope limit: this is an FRU-level repair manual. HP states that the removal chapter covers field-replaceable units and does not support repair of individual subassemblies or component-level troubleshooting. That distinction matters if you are looking for board-level electronic repair instructions rather than factory assembly replacement procedures.

The manual specifies ordinary bench tools rather than proprietary HP fixtures: #2 Phillips screwdrivers, a small flat-blade screwdriver, needle-nose pliers, an ESD mat, and a penlight. The product power switch only interrupts DC from the low-voltage power supply; AC remains present internally whenever the power cord is connected. Unplug the printer before internal service.
