HP LaserJet Pro 300/400 color MFP M375/M475 Series Product - Install memory DIMMs

This product comes with 192-megabyte (MB) random-access memory installed. You can install an additional 256-megabyte of memory for the product by adding a dual inline memory module (DIMM). You can also install a font DIMM to allow the product to print characters (for example, Chinese language or the Cyrillic alphabet characters).
  caution:
Static electricity can damage electronic parts. When handling electronic parts, either wear an antistatic wrist strap, or frequently touch the surface of the antistatic package and then touch bare metal on the product.

Install memory DIMMs

  2. On the right side of the product, open the DIMM access door.

Check DIMM installation

After installing the DIMM, make sure that the installation was successful.
  1. Turn the product on. Check that the Ready light is illuminated after the product has gone through the startup sequence. If an error message appears, a DIMM might have been incorrectly installed.
  2. Print a configuration page.
  3. Check the memory section on the configuration page and compare it to the configuration page that was printed before the memory installation. If the amount of memory has not increased, the DIMM might not be installed correctly, or the DIMM might be defective. Repeat the installation procedure. If necessary, install a different DIMM.
note:
If you installed a product language (personality), check the "Installed Personalities and Options" section on the configuration page. This area should list the new product language.

Memory allocation

Utilities or jobs that you download to the product sometimes include resources (for example, fonts, macros, or patterns). Resources that are internally marked as permanent remain in the product memory until you turn the product off.
Use the following guidelines if you use the page description language (PDL) ability to mark resources as permanent. For technical details, see an appropriate PDL reference for PCL or PS.
  • Mark resources as permanent only when it is absolutely necessary that they remain in memory while the product is turned on.
  • Send permanent resources to the product only at the beginning of a print job and not while the product is printing.
note:
Overusing permanent resources or downloading them while the product is printing might affect product performance or the ability to print complex pages.
