Okay, At last, I found info on the HP website http://www.hp.com/cpso-support/deskjet/solutions/prq/cartclean.html wherein there is enough info about cartridge cleaning etc. using buttons on the printer. Hope this helps lots of other DeskJet users. Ashok -------------------------------------------------------------------- The Linux India Mailing List Archives are now available.
