HP LaserJet Enterprise 500 Color M551 n/dn Formatter Logic Board CE941 60001

Item Description

Up for sale is a genuine OEM HP Main Formatter Logic Board, cleanly pulled from a working HP LaserJet Enterprise 500 Color M551n printer. This board is used but works great—it has been fully inspected, tested, and is guaranteed to be stable and operational.

The formatter board functions as the primary "brain" of the printer, managing user print jobs, interface connections, network communication, and data processing. If your printer is locking up on the initial splash screen, stuck in a boot loop, failing to wake up from sleep mode, or dropping LAN/USB connectivity, replacing this main formatter assembly is the definitive solution.
