Computer Memory Solutions 64MB PC100 SODIMM memory upgrade for HP LaserJet 4000 series

64 MB SODIMM for HP LaserJet 4000 printers

This 64 MB PC100 SODIMM module upgrades the memory in HP LaserJet 4000, 4000N, 4000SE, 4000T and 4000TN printers. It uses a 100-pin SDRAM form factor and operates at 100 MHz with CL2.5 timing. The stick is designed for office printers that need more buffer space for complex print jobs.

Sustained print workloads

Under continuous printing the unbuffered SDRAM runs at a steady 3.3 V and maintains the rated 3-3-3 timings without active cooling. The major-brand chips handle large spool files and graphics-heavy pages without throttling or parity errors because ECC is not present. The module keeps its specified speed across long print queues in a typical office environment.

100-pin SODIMM build and fit

The low-profile circuit board has no heat spreader, so it fits the tight printer socket without clearance issues. Gold edge contacts resist oxidation during the printer’s multi-year service life. Installation is a simple press into the single SODIMM slot on the formatter board, and the 64 MB capacity matches the maximum addressable limit for these LaserJet models.
