Enabling Cartridge Out Override Feature

Hello,

I have a HP LaserJet CM 2320. I want to try to continue using the printer cartrides even after the printer tells me to replace them. I know there is still ink left and I want to use every last drop before replacing them.

I found instructions on how do it  here - http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_ba847bafb2a2d782fcbb0710b053ce01=wsrp-navigationalState%3DdocId%253Demr_na-c02266144-3%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.tpst=ba847bafb2a2d782fcbb0710b053ce01&ac.admitted=1397588307869.876444892.492883150

I tried method two which involves using HP Toolbox FX through the computer. Supposedly all I have to do is turn on the "Auto Continue" feature and it will continue to print even when the cartridge is out. However, This does not work. I switched the "Auto Continue" feature to ON and it just prints in black. My yellow cartridge is out so I did a test and printed in yellow but all it does is print in black.

There are instructions on how to enable the cartridge out overide feature through the control panel on the front of the computer but unfortunately my LCD panel is out. Can someone please give me instructions on how to do this without being able to see the LCD panel. In otherwords I need very specific instruction on what buttons to push and how many times to push them and in what order. I cannot see the LCD displace so I will not be able to navigate.  Assume I am a blind man and cannot see.

Thank you for your help.
