Canon M5 banding- Nozzle Optimization/ Printhead alignment Grayed out

[Goooost]

Hi, recently our Canon M5 has been showing signs of horizontal banding, and I'd like to fix it. However, all the options to automatically diagnose and fix it are grayed out. All the tools that include "Automatic nozzle optimization" show an uncheckable checkbox. It just says "print on" but does not show either roll as options to print on. Same thing with printhead calibration and printhead carriage calibration. These suggest that I only need to load a smooth matte opaque paper, but the start button is grayed out.
My understanding is that this is usually due to incompatible stocks, but nothing I've loaded into the machine seems to trigger as compatible. I've tried 3M IJ35, 3M IJ40, 3MIJ180, Drytac SpotOn, some generic poster papers, something specifically labeled in our shop as "Canon Service Paper", noncurl banner... all 54" rolls. According to AI some of these are specifically mentioned as compatible papers for these processes. Nothing seems to trigger these tools to become available, so I was hoping there was some stupid step I was missing. I've heard that I need to first run a manual maintenance, but that still doesnt activate it either.
Another suggestion was to first recalibrate the paper stock I'm using, but calibration fails for unspecified reasons. It just cuts the paper off at about 36 inches and tells me to remove it from the output sensors and then says "Calibration failed".
Anyone have any ideas how I can get the printer to perform these automatic nozzle or printhead calibrations? My predecessor seems to have never gotten it to work either so it's probably been at least 2 years since any of these were run.

Edit- While I wasnt able to calibrate my IJ35 I was able to calibrate my IJ180, however the problems persist. Maybe IJ180 isnt a compatible paper? However I should mention that even though I cant recalibrate that IJ35, its status is still calibrated- it was calibrated 2 years ago. So I'm inclined to think calibration has nothing to do with it.

The Canon service paper should definately work......have you tried a reboot yet?

I have rebooted it from the system control panel. I havent done a shutdown but we did have a power outage which I figured is the same thing. I've also reinstalled the printer on Onyx
I havent yet tried downloading a new paper profile and putting it into onyx media manager.

In Output Configuration, try changing "Wind the Output" to No. I don't know why it works but that usually solves the grayed out problem. I think it's a bug only on the M because the 1650 doesn't seem to have that problem.

Mine did that (grayed out nozzle optimization) . it was greyed out for a few weeks and I needed to run it. Had Canon tech come out for a different issue and after he worked on the printer the option came back, I don't remember what he fixed but it wasn't anything related to the nozzle optimization, it was maybe the encoder strip that was replaced

I definitely keep this option on all the time because I can always choose to use it or not after the fact it seems like a no brainer to just have it on. I think this will end up being the answer, and it probably has something to do with the output sensor.

It will be the first thing I try tomorrow.

Yea, mine is always on as well. It’s only off every once in a while if I’m printing something just big enough to catch the take up real but then wastes the rest because it doesn’t rewind back to the end of the print. I think it’s right around 23”.
