Condensed version as follows.
Original issue : Contacts in carriage peeled off and printer just kept saying to reseat printhead. Ordered carriage assembly, Replaced carriage assembly, did electronics test on the carriage after install to make sure nothing was missed. and it failed on the last test. results are as follows
SOL sensor not detectable using this test right now
Trying to access Tetris
Tetris OK
ALL 6 pens present
all 6 pen communication OK
PEN 0 CSIO fails
Test failed
I went ahead and started it up and reinstalled the printheads, all installed with no issue. went to service to do the line sensor calibration and that is where it got a bit odd. everything looks as if its progressing fine. I get the RGB values and when i push OK it says calibrating and then fails 86:5:46 code
ALSO
when I try to test print I get the message
No jobs can be Printed
An Ink cartridge or printhead needs replacement
check status and replace to continue
all ink and printhead status' are checked with no issue showing.
I have attached pictures of each screen.
