Install memory, internal USB devices, and external I/O
cards
Overview
The formatter has the following open slots and ports for expanding the product's capabilities:
●
One dual inline memory module (DIMM) slot for upgrading the product with more memory
●
Two internal USB ports for adding fonts, languages, and other third-party solutions
●
One external I/O (EIO) slot for adding an external print server, an external hard disk, or a parallel
port
If the product already has an embedded HP Jetdirect print server installed, you can add an
additional networking device in the EIO slot.
For information about ordering specific components, see
Supplies and accessories on page 199.
To find out how much memory is installed in the product or to find out what is installed in the USB ports
or the EIO slot, print a configuration page.
Install memory
You might want to add more memory to the product if you often print complex graphics, print PostScript
(PS) documents, or use many downloaded fonts. Added memory also gives you more flexibility in
supporting job-storage features, such as quick copying.
This product supports printing PDF files when 96 MB of memory is installed. However, for the best
performance, upgrade the memory to at least 192 MB.
NOTE: Single inline memory modules (SIMMs) used in previous HP LaserJet products are not
compatible with the product.
Install product memory
This product has one DIMM slot.
CAUTION: Static electricity can damage electronic parts. When installing DIMMs, either wear an
antistatic wrist strap or frequently touch the surface of the DIMM antistatic package, and then touch bare
metal on the product.
1. If you have not already done so, print a configuration page to find out how much memory is installed
in the product. See
