'Same drama' - with different inks - I have some reservations that all the reported problems are just a matter of the 'wrong' ink; I rather would assume that there are some functional problems with the CISS - e.g. wrong internal pressure in the tubes from a wrong ink level - impacting the ink...
Or you switch over to a printer which meets your requirements - the already mentioned Frontier DL650 printer , the printer does backside printing on media which are suitable for that printer
Just look for the specs

It's just the OBA's which cause the increase of the white level, and it is correct that some Canon papers have a pretty strong OBA content e.g. the Platinum PT101 - higher than an Epson Premium glossy, but be aware that such whiteness increase is only visible in an environment with some UV...
There are some driver settings which use the color inks even if you select monochrome/BW printing - like borderless printing or printing on glossy paper.
Please get the essence of this thread - members here consider the Datac.......... profiling package as rather ........You may look alternatively for a used i1Studio or ColorMunki package if cost is a rather big concern for you.
And you could use the freeware ArgyllCMS software together with an...
Canon Megatank printers are plagued by air in the supply tubes to the printhead which is causing effects just as you describe them - the printhead is not blocked but you have air instead of ink supplied to the printhead nozzles. You may scan through these postings and/or find more on the...
I found some instructions by Brother how to dry and store photos after printing, Brother specifically mentions that the colors of inkjet prints need some time to stabilitze, this is very important for the profiling process when patch sheets are printed and scanned, and for judging the color...
A good photo paper of the RC/PE type is just as you experience it - the paper base is sandwiched between very thin PE foils - on both sides , and a RC (resin coated) layer is added wlhich is the active surface to print onto. You cannot print directly onto the PE film. You probably would need...
No, I'm doing profiles for 4x6 inch papers with 96 patches with i1Profiler and never have seen such effect. Photo papers of all kinds - glossy - silk - baryta whatever etc run with a white point of L*= 90 to 95 for the luminance of the white point. You need to check the data file/sheet with the...
There is a serious problem - your profiles assume a white point at L=67 - that's a medium gray but not white at all.
But I can't tell you why you are getting such results.
I'm not familiar with ArgyllCMS profiles so I can't interpret your numbers and tell if they are good or not so good.
The i1Profiler software is free and can be downloaded from the resp. internet pages, you need an older version - I think 3.1 or below - which still supports the old i1 spectro -...
You would need the service manual to find the sensor(s) causing this error condition, a sensor may be blocked or covered up by a small piece of paper or mechanically inhibited.
I did another measurement cycle after 3 months - the patch sheets were kept in the dark for this period, the previous measurements were done 1 month after print and posted in #5. I'm showing the total averaged color shifts for the period from 1 hour after print till today after 3 months and as...
