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?
