Item Description
Up for sale is a genuine OEM HP Drum Motor Drive Assembly, cleanly pulled from a working HP LaserJet Enterprise 600 M603 printer framework. This motor has been fully inspected, terminal pins checked, and is guaranteed to be in 100% operational condition (used but works great).
This primary motor (designated as M102 in the factory service manual) drives the photosensitive imaging drum, primary charging roller, and transfer roller. If your printer is throwing grinding gear noises, motor startup failure codes, or stalling during page cycles, replacing this main drum drive unit is the direct fix.
Key Features & Details
Tested & Working Great: Pulled from an active machine; the factory plastic pinion gear teeth are completely clean with no stripping, flattening, or premature wear.
Genuine OEM Part: Original HP internal motor component stamped RM1-8358, ensuring exact mechanical torque compliance and electrical signal feedback to the DC controller board.
Drop-In Fit: Features the standard 3-hole structural mounting plate and the integrated 4-pin white wiring connector housing without any modifications.
Compatibility
This drum motor assembly features wide cross-compatibility across multiple heavy-duty enterprise frameworks:
LaserJet Enterprise 600 Series: M601n / M601dn, M602n / M602dn / M602x, M603n / M603dn / M603xh

Tech Note: Before installation, make sure the printer is completely powered off and unplugged from the wall. Ensure the motor sits perfectly flush against the interior chassis frame alignment brackets before tightening down the mounting screws to avoid off-axis gear binding or premature teeth wear.
