HP 4100TN, 4100N manual Checking memory installation, Saving resources permanent resources

Checking memory installation

Follow this procedure to verify that DIMMs are installed correctly:

1Check that the printer control panel displays READY when the printer 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 111).

2Print a new configuration page (see “Configuration page” on page 152).

3Check 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's memory until you turn the printer's power off.

Use the following guidelines if you make use of the PDL (page description language) 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's 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 decrease the printer's performance or its ability to print
	complex pages.
