A correction: R1, R5, R6 measure 100K; R2, R3, R4 measure 200K. This is true of 2 different PCBs (the "subject" printer and a used spare), both from printers with the same error code.
Maybe a manufacturing error (ie, these were supposed to all be the same value)?
Ideas?
Thanks.
True enough. If the printer gets set in 'photography' mode, the black hues get printed with an excess of color ink, sometimes. I had a LONG session getting a printer reset after that happened, the menu selections were demonically incomprehensible. And, of course, it used three expensive color inks instead of the cheap black ink, until the problem was fixed.

Hi. In that printer there is a sensor that can verify the presence or air bubbles in the ink circuit. I don't know if your piece is that sensor, but there is. I am trying to fix a C6180 with the wll known ink system failure problem: i can't find the service manual but i think i can have a failure of the pump motor or of the circuit that control this motor. The pump is located (in my case) in the left side of the printer (facing the control panel) and (my thought) there is no sign of life of the related motor even if i switch off and on the printer. I am not sure about that: maybe this pump works only when a new set of cartridge is installed in the printer (initialization) but, in my case (following the instructions found on the net), i was not able to force a cycle to eliminate trapped air. If you have any solution, please, msg to me. Thx Slang
