256MB upgrade for HP LaserJet Pro 400

This 256MB memory card expands the RAM in HP LaserJet Pro 400 Color MFP M475 and M451 series printers. It suits offices that handle larger print jobs or complex graphics and need the device to buffer more data without slowing down. The module is built for the listed models only.

Simple DIMM slot installation

Installation means opening the printer's memory cover, aligning the notch on the card with the slot key, and pressing firmly until the latches click. The most common issue is the printer not recognising the new capacity, which usually means the module is not fully seated or the firmware needs a cold restart.
