Yuck, the problem with free printers and ones you don’t use is that they clog and jam. Printing is so 20th century! Anyway for this one, the documentation http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=4311836&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c02206095-21%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken is incorrect.
There is a Mac Utility to do this and it is in the printer driver area. We tried to run cleaning twice and it didn’t work.
But if you set it to photo mode, then somehow it is good enough.
