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.


Overusing permanent resources or downloading them while the product is printing might

affect product performance or the ability to print complex pages.
