The object of the test print was not to see how well it printed (Quality wise) but merely to exercise the print head and get some ink flowing through it which can help clean out any reluctant ink deposits remaining inside.
@The Hat
So I should continue to run a few sheets or cleaning cycles daily until the nozzles become clear? Should I wait between each? Would there be a max to do per day? Would there be a point to say it's not recoverable (like after x amount of prints or days)?
Another thing that I am still noticing is that the ink monitoring is VERY off.
Ink monitoring is saying that inks are empty then they are nearly still at 100%
This is after many purges from switching cartridges and removing the printhead a couple of times.
Printing over 12 of the test pages
Several cleaning cycles over these few days
and many many test pages (which I assume use very little ink tho)
Again the black and magenta were refilled (and reset) and gray was replaced with a third-party ink to try different cartridges.
Is this normal?
I can remember the first time I got the ink empty notice I took the cartridge out and replaced it with 3rd party inks (which I regret) but then I noticed there was at least 1/3 of ink in the reservoir (where the liquid ink is, not the sponge side), almost half in some other colours. I remember making a comment to my wife on how it interesting I can see how much ink is actually left, and it said empty when it really wasn't.
Is it normal that since the beginning I've been having 1/3 of the ink left, and upwards of half still left in the cartridges?
Now it's reporting empty but my cartridges are still full, and these are the OEM ones that I got, not refill or reset.
It doesn't seem like the printhead is using the full amount of ink that is meant to be, the ink should be a lot more used?
Let the printer rest over night then print a nozzle check the next day. If defects still present then you can either run a couple Regular Cleaning cycles OR run The Hat's 6 test print test again. Whichever route you decide, then run a nozzle check, scan, crop and post. JPG and PNG are acceptable besides PDF.
I printed 6 more of the test prints and here is the nozzle
I personally compared to the nozzle check I did this morning don't notice much of a change, maybe yall can see if looks better or the same still?
Here is what it is at now
Here was it this morning before any test pages

(sorry about the back of this one, been reusing as I've been printing so many nozzle checks that didn't want to scrap papers after one use)
Thanks for your continued help it has been very much appreciated so far!
And rain would be nice, I only get snow, snow and more snow. But hey at least it's only -20c and sunny

! Could definitely be worse lol.
