The RC Original Refurbished Power Supply Board (STR Old Model Type) is an OEM-quality replacement designed specifically for the HP LaserJet M1005 MFP (Old Type Model) printer. This Low Voltage Power Supply (LVPS) converts AC input into regulated DC voltages required to operate the formatter board, engine controller, scanner assembly, motors, sensors, and fuser unit.
A faulty power supply board can cause the printer to remain completely dead, fail to start, restart unexpectedly, or stop during printing. This STR Old Model power supply has been professionally refurbished, tested, and verified to restore stable power distribution and reliable printer performance. Compatible with RM1-3942, RM2-0375, and RM2-8109 power supply assemblies.
Ideal for printer technicians, service centers, refurbishment businesses, and professional maintenance.
