z3100 Reseat printhead problem

[A. Andrew Gonzalez]

Has anyone run into this problem or could help?
Printing stopped with a massage to reseat the EG printhead. So I followed the menu instructions, reseated the printhead and it returns the same reseat printhead message. So I reseat several times, now the message says to replacement is not complete for all the printheads! Now I reseat all printheads ... again same message!
Any thoughts?... guess it's time to call HP
Thanks
Andrew

Andrew,

How is the cleanliness of the inside of the printer?

[A. Andrew Gonzalez]

Looks clean, Maybe a few specks of dust. Is there a specific area I should be looking at?
The heads looked clean as well
Thanks!

Other users have noted that ink and especially gloss enhancer can end up inside the printhead compartment and on the metal contacts (where the printhead interfaces with the carriage). Try cleaning off the contacts with distilled water on a microfiber cloth or no-lint swab, then re-seating the printhead. I haven't had the problem myself, though I did have to replace one printhead shortly after I got the printer after a head crash due to incorrect paper preset selection on my part. Initially the printer told me to reseat the printhead; after a few tries it gave up and told me to replace it. So I did, and all was good.

Hope this helps.

Thanks, ... I'll work on cleaning the contacts tomorrow.
I'm a bit fatigued from stressing over this.
Time to open a bottle of wine and chill for the evening.

Well, Cleaned the printhead contacts (on the printheads and carriage). A couple of them had quite a bit of ink splattered on the contacts... is this a design flaw?
Anyway, didn't work. Same problem as before.

Similar messages appeared when I cleaned 6 heads and reinserted them again. After more cleaning and carefully drying the contacts in the inkslot itself too the printer accepted the heads. Don't give up yet.

Thanks Ernst,

I again carefully cleaned the printhead contacts and the contacts on the carriage three more times.
Carefully drying the contacts before re-seating. I used distilled water and coffee filters tightly wrapped around a flat popsicle stick.
Seems the plastic part around the contacts on the carriage are slightly stained with ink,.... no amount of cleaning removed this. I don't think I can get them any cleaner.
Still the same problem.
HP Tech support wasn't much help.
HP is shipping (should arrive today) a new EG Printhead, since this is the one that initially caused the problem. Hopefully replacing that one will be the solution.
Very Frustrating during a busy season

Problem resolved
Looks like the EG printhead was the problem. HP sent a new printhead and now all is well.
What through me off was that it would continue to show that all printheads needed to be replaced.
 
Thanks again
Andrew
