One look >by the repair technician and out the door you go. > I have been hearing all this "concern" that the "bogus" ink would clog the primer on the printer for 1 1/2 years now! I also have been in contact with several people on the net who have been refilling the cartridges (as do I) so a long time now! Has ANYONE personally seen or heard of a first-hand case of the primer becoming defective in a DeskJet? If so, was is due to "bogus" ink?? I am going to be very surprised if anyone has really seen this happen!! A few moments examining the print head set-up in my Deskjet would indicate that the actual "jets" of the head are SEALED shut by a rubber seal (I guess this is the "primer tube" opening? If this is not the case, and assuming that ink is supposed to collect in this "primer tube" in a liquid state and remain that way, how does the original HP ink perform this magcic?? I have been under the impression that the priming action actually was the result of an increased elctrical drive signal to the cartridge to force more ink into the jets. Is this wrong? Would someone from HP please, at least unofffically, respond to this issue? ========================================================================= | Jeff Long jlong@afit-af.mil (ARPA net) | | | | humble (and getting humbler by the day) graduate student; | | The Air Force Institute of Technology (what a great way of life??) | =========================================================================
