HP LaserJet P3010 Series Printer Service Manual, 2009 (P/N CE524-90909)

This HP OEM service manual covers the LaserJet P3010 Series, including the P3015, P3015d, P3015n, P3015dn, and P3015x configurations. Edition 1 (July 2009), P/N CE524-90909, combines factory theory, field-replaceable unit (FRU) repair procedures, diagnostics, error-code troubleshooting, parts identification, and electrical documentation.

Searchable PDF with Bookmarked Service Sections

Text search and circuit detail: Searchable PDF text and embedded bookmarks provide access to operating theory, repair procedures, troubleshooting, parts, and appendices. Small pin numbers and signal labels in the general circuit diagrams require zooming.

Supplied as one printable 342-page PDF, including 14 pages of front matter, the 326-page numbered manual, and two closing pages.

Paper-Path Diagnosis and Printer Assembly Repair

The following selected service topics show the manual’s repair and diagnostic scope. Other included subjects cover print registration adjustments and optional hard-disk initialization.

• Factory diagnostics: Engine-test and fuser-test pages, paper-path tests, automatic and interactive sensor tests, component tests, half self-test, and drum-rotation checks.

• Paper-feed repairs: Step-by-step procedures for pickup rollers, separation pads, the transfer roller, registration assembly, and duplex media-feed assembly, including optional feeder components.

• Electronic assemblies: Illustrated removal and replacement procedures for the formatter PCA, laser/scanner, engine control unit (ECU), and high-voltage power supply (HVPS).

• Cooling and drive components: Main and sub fan replacement, environmental sensor service, fuser motor replacement, and Tray 1/Tray 2 pickup-solenoid procedures.

• Error diagnosis and service functions: Control-panel messages, event-log troubleshooting, NVRAM initialization, cold reset, firmware updates, and service-mode functions.

• Parts and electrical references: Exploded assemblies, configuration-specific service part numbers, connector maps, timing charts, and general circuit diagrams.

The internal repair procedures suit printer service technicians trained in electrical isolation and ESD handling.

Fault Isolation Before Assembly Replacement

The diagnostic section is built around isolating paper-path and image defects before assemblies are replaced. Engine and formatter checks help distinguish print-engine faults from formatter or control-panel problems.

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.

Model differences: Automatic duplex functions apply to the d, dn, and x models; the P3015 base model does not support automatic two-sided printing. The manual also covers the Tray 3/Tray 4 500-sheet feeder system and its separate electronics.

Service settings: NVRAM initialization affects stored configuration, calibration settings, serial-number information, and page counts. The manual distinguishes this procedure from a cold reset and documents restoration of service information after formatter replacement.

Engine Control, Fuser Circuits, and Wiring

The theory section explains DC-controller coordination, formatter operation, the electrophotographic process, toner-cartridge memory-tag communication, jam detection, and the low- and high-voltage power supplies.

Fuser coverage identifies heater H1, main and sub thermistors TH1/TH2, thermoswitch TP1, and the heater-control and safety circuits. Failure descriptions address start-up, low-temperature, high-temperature, and zero-crossing detection.

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 and harness references support electrical tracing. The formatter procedure identifies J14, J17, J16, and FFC J18; the ECU map connects motors, fans, sensors, solenoids, fuser circuits, and the formatter to their respective connectors.

Replacement Parts and Repair Limits

Configuration-specific parts: The parts chapter distinguishes 110 V and 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. Maintenance kits are CE525-67901 for 110 V and CE525-67902 for 220 V units.

Repair depth: The removal chapter covers FRUs. HP does not support repair of individual subassemblies or component-level troubleshooting, so this is an assembly-replacement reference rather than a board-level electronics repair guide.

Handling cautions: HP flags possible fuser damage when removal is attempted with the cartridge door open, and warns that removing the HVPS gear cover can dislodge unsecured gears. Bent, folded, or incompletely seated FFCs can damage a PCA; incorrect laser/scanner FFC reconnection can also trigger a 51.1 error.

Required bench equipment includes #2 Phillips screwdrivers, a small flat-blade screwdriver, needle-nose pliers, an ESD mat, and a penlight. The power switch only interrupts DC from the LVPS; AC remains present internally while the power cord is connected. Unplug the printer before internal service.

Examples of Print-Stop and Repeating-Defect Data

The print/stop test is programmable from 0 to 60,000 ms. Example positions include stopping before the fuser nip at 500 ms and, during duplex printing, about 15 mm beyond sensor PS502 at 3,000 ms.

The repetitive image-defect ruler links spacing to likely 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.

The LVPS documentation identifies +3.3 V, +5 V, and +24 V rails, while the HVPS section maps charging, developing, transfer, and fuser-film biases.
