512 MB DDR SDRAM DIMM for HP LaserJet printers

This 512 MB DDR SDRAM DIMM uses a 100-pin interface and matches HP part numbers Q2628A and Q7720A. It is designed to expand the memory of compatible HP LaserJet 4250 series printers, including the 4250n, 4250tn, 4250dtn and 4250dtnsl models. The module installs directly into the printer’s DIMM slot to increase buffer capacity for larger or more complex print jobs. It is supplied new and ready for installation.

Fits 100-pin DIMM slot in supported HP LaserJet

Installation requires an available 100-pin DIMM slot on the printer’s formatter board; no additional cabling or power connections are needed. Adding this memory frees up the printer’s internal resources by allowing more pages to be spooled locally, reducing wait times when multiple jobs are sent. It does not work with printers that use a different pin count, memory type or form factor. Buyers who need higher capacity than 512 MB or a different interface should verify their printer’s specifications before ordering.

Questions about this item

Will the 512 MB DDR SDRAM DIMM reach a page-count ceiling during long print jobs on the 4250 series?

The module adds 512 MB of buffer memory so the 4250, 4250n, 4250tn, 4250dtn and 4250dtnsl can hold larger raster jobs before spooling to disk.

Does the 100-pin DIMM increase fan noise or power draw when the LaserJet 4250 runs continuously?

The memory board is passive with no fan or active cooling; it draws only the small standby current the 4250 printer supplies through the 100-pin slot.
