256MB Memory Upgrade for HP LaserJet Pro 400

This 256MB memory card is designed for the HP LaserJet Pro 400 series, including the M451dn, M451dw and M451nw models. It expands the printer's internal memory to handle larger print jobs and more complex documents. The module is tested for 100% compatibility with these specific devices. It suits offices that experience slowdowns or memory errors when printing graphics-heavy files.

Supplied as a Single Memory Module

The package contains only the memory card itself, with no additional cables, software discs or installation tools. Users must rely on the printer's existing firmware and control panel to recognise and configure the new memory. No driver downloads or separate utilities are required for operation. Buyers needing multiple modules for other printers or higher capacities must source them separately.

Questions about this item

Will the 256MB memory card require any maintenance or replacement after installation?

The 256MB memory card is a solid-state component with no moving parts, so it requires no scheduled maintenance or periodic replacement under normal printer operation.

What limit appears first when the printer runs sustained high-volume jobs with this 256MB upgrade?

The 256MB capacity sets the maximum buffer size for complex pages; once that buffer fills, the printer pauses to process data before accepting more.
