Checking memory installation
Follow this procedure to verify that DIMMs are installed correctly.
To check memory installation
1 Check that READY appears on the printer control panel display when the printer power is
turned on. If an error message appears, a DIMM might have been incorrectly installed.
Check the printer messages. (See
“Understanding printer messages” on page 109 ).
2 Print a new configuration page. (See “Configuration page” on page 83 .)
3 Check the memory section on the configuration page and compare it to the configuration
page printed before the DIMM installation. If the amount of memory has not increased, the
DIMM might not be installed correctly (repeat the installation procedure) or the DIMM might
be defective (try a new DIMM).
Note If you installed a printer language (personality), check the Installed Personalities and Options
section on the configuration page. This area should list the new printer language.
Saving resources (permanent resources)
Utilities or jobs that you download to the printer sometimes include resources (for example,
fonts, macros, or patterns). Resources that are internally marked as permanent remain in the
printer memory until you turn the printer power 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 printer power is turned on.

Send permanent resources to the printer only at the beginning of a print job and not while the
printer is printing.
Note Overusing permanent resources or downloading them while the printer is printing might affect
printer performance or the ability to print complex pages.
