Checking memory installation | HP 5100LE instruction

Checking memory installation

Follow this procedure to verify that the DIMMs are installed correctly:

1Check that the printer control panel shows the READY message when the printer is turned on. If an error message appears, a DIMM might have been incorrectly installed. Check the printer messages.

2Print a new configuration page.

3Check the memory section on the configuration page and compare it to the configuration page that you printed before the DIMM installation. If the amount of memory has not increased, the DIMM might not be installed correctly. Repeat the installation procedure to verify that the DIMM has been installed correctly. If the amount of memory has not increased after this reinstallation attempt, install a new DIMM to discover whether the first DIMM is defective.

Note	If you installed a printer language (personality), check the Installed Personalities and Options
	section on the configuration page. This section should include the new printer language.
