Need Help Finding Previous Post

[vienna01]

Search is great if I can ask it correctly to get the answer needed.

About 2 months or more ago, there was a post that explained
HOW TO PUT TAPE ON THE CONTACTS OF A CANON PRINTHEAD SO THAT YOU TELL IF THE NO-PRINTING PROBLEM WAS PRINTHEAD or SOMETHING ELSE.

I think there was a photo of the printhead with the tape applied too.

Can SOMEONE point me to that post or thread?

I remember that our print head expert @Łukasz was the one who published the idea of masking some contact pads on a print head for diagnostic purposes.

Using the forum's search feature and doing a search on "tape AND printhead" posted by Łukasz, finds these 6 threads, all about the subject and with photos: 1 2 3 4 5 6

I think this is what you are looking for.
