Downloading custom color profiles
Obtain custom color profiles just as you would any other remote-firmware update, using the procedures
described in these sections.
Custom color-profile .RFU files are named as follows:
clj####_<what>_<version>.RFU
where:
●
#### is the product-model number of the color table
●
<what> is a one-word description of what the table does
●
<version> is a two-part version number consisting of a major and a minor value
For example, some custom color-profile .RFU files that could be available include:
●
A simulation of the color settings for the HP Color LaserJet 4650 product:
*clj4650_*.RFU
●
A remote-firmware-update file that resets your product to its original state:
*reset_*.RFU
While every care is taken to ensure a close match with the colors available on the product, several
factors can affect the outcome of the match:
●
Differences between products within and between a given model line
●
paper type
●
The age and state of the custom-profile product and the product to which the profile is to be
downloaded
●
The use or non-use of genuine HP supplies
●
