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.
