The HP Q7847-61006 formatter board is the main logic PC board for the HP LaserJet P3005 series. It is intended for the P3005 and P3005d series, providing a replacement formatter assembly for these printer models.
This is the non-network version of the formatter. The network formatter is identified separately as Q7848-xxx, so the distinction matters when matching the board to the printer configuration. The listed board version is 02.041.0.
