Do you think isopropyl alcohol alone is as good as mixing with Windex
(which I would have to buy and never use again)?
It seems that 70% IPA is best for killing germs, and 91 or 99% is not
good at it. Is 91 or 99% much better for cleaning inkjet heads? If
so, it seems from what I read that after I use it, the bottle could be
left open and after a while it would turn into 70% IPA.
BTW IPA is cheaper at the local pharmacy than at Amazon. My impression
is that products with a lot of water or other liquid are expensive
online because of indidividual shipping costs, but I might be imagining
this.
Can you use the wrong color cartridge in an inkjet printer?
Can I print or clean with a yellow cartridge where the red should be?
I would assume colour laser printers to be "idiot proof"
Can I print or clean with a yellow cartridge where the red should be?
My red no longer prints, running the clean routine 7 times makes 1 or 2
new dots print red each time while prior dots become blank. So I still
only print 3 dots out of 195.

Are you sure that the cartridge isn't empty. If you use third party cartridges with to less ink, the printer doesn't know that there
is no ink left.

Specifically in a Brother printer, if you know, although I'm curious
about other brands too.
This Brother printer MFC-J625DW has never complained about off-brand
ink, and has worked well for years**, but it does ask after I replace a cartridge if it was the color for the slot I put it in.

The reason 100% alcohol isn't as good at cleaning "germs" as the mixes with >water is that the germs which are bacteria (not all germs are bacteria >though) are designed to absorb water. Probably fungi too. Not viruses.
Viruses aren't living organisms.
As for refilling, I used to buy the inexpensive (I thought) HP printers at >Costco and then the expensive HP printer ink at Costco, thinking I'd refill >them on my own.
That worked for a while until I realized HP added an expiry chip.
The solution after years of playing these silly games was a laser printer.
Black and white.
Kids went to kinkos once they got to high school age if they needed color.
Still using the black & white but now I refill it with plastic powder once >every five years (it used to be around once a year with kids at home).
The grandkids think black & white printing is a throwback to the fifties.

Normally, no.
Most printers have code to verify/check the installed consumable(ink >cartridge - type/brand/color/etc) before ok'ing for use.
Until corrected, the printer doesn't/may not work.

As near as I could determine yesterday, the ink delivery system on
that inkjet, is "two-parts". The thing that plugs into the front
module, just holds ink. You should have noticed this Micky, instead
of torturing us. Of course your printer is different.
Ink reservoir --- internal_print_head ---> paper
Whereas my printer here, a Canon Inkjet, is like this. Most of
the modern and dirt-cheap printers, work this way. These are the
kind you don't want to own. The material cost of the carts is higher.
removable_print_head ---> paper
plus ink reservoir
all in one module
with extensive
electrical contact
plate
The Ink Reservoir on the Brother, does seem to have
electrical contacts, but they would be mainly for enumeration.
The fill of the reservoir, may be checked optically somehow.
A clever individual, would now look at the part of the
reservoir, and count the number of contacts. If no silicon chip
is evident, the contacts could be "grounds" for ID, and you'd
need a ground contact, plus ID0 and ID1 bits. It it was an SPI
or some other serial standard and had silicon, maybe there would
be additional contacts for silicon chip power. To do an ID,
should not need more than five contacts.
The design of the Brother, is one stop short of a "tank inkjet".
Where tanks of ink, like a liter of red, sit below the
printer, and the printer pumps the ink as needed for itself.
Such printers are cheap to operate, as you only need change
a print head, when it wears out or plugs up from lack of usage.
You would not purchase a "tank inkjet", unless you printed
all day, every day, and the action of doing that, helps
keep it running in top shape.
And with a tank inkjet, and the damaging fluids it possesses,
you arrange the printer so there is a "catchment basin" to stop
an ink leak from damaging your carpets. If a bottle holds a liter
of ink, think of the size of the spot on the carpet that would
make. It could even drip onto something on the floor below.
The piddly little carts my machine uses, usually staining your hands
is the extent of the damage. And your cheap desk is ruined :-)

You can look up Windex on Wikipedia.
Straight ammonia used to be a readily available cleaning product
("cuts grease, good window cleaner"), but it has been for the most
part, removed from the shelves.
An example here, at a ridiculous price...
This used to be only a couple bucks a bottle, because large quantities
of this are made for farmers. This is expensive enough, a four liter
bottle would be worth as much as an analytical grade bottle of the chemical.
https://www.walmart.ca/en/ip/900mL-Ammonia-All-Purpose-Cleaner/PRD2OQYVRDZRBCB
The Windex includes surfactants (like a detergent), so that may be
why it is working in this case. It's hard to say what part of the
Windex is most effective. Then the question would be, what kind of
residues does it leave behind, and would those residues affect
the ink pumping action (change drop size).
https://en.wikipedia.org/wiki/Surfactant
This is why I prefer pure chemicals, to make it easier to predict
an outcome. Ammonia is a pretty good cleaner (as I used to make
my own bottles of window cleaner here). Even without surfactants,
it cleans glass nicely. The bottle sez "attacks aluminum and copper".
I don't remember any attacks as such.
Don't breathe ammonia vapors in, as it's bad for your lung lining.
*******
The prices on the bazaar selling sites for chemicals, is
just ridiculous. The last bottle of IPA I bought, was
probably three or four times the proper price. The stores
are having a field day, when you know the factory making the
chemical is not jacking the price like that. Only the
retailer is raping the public. The middle men are driving Lambos.

Well that is expensive but try this: https://www.instacart.com/store/giant/products/3192675
To make a great mirror and window cleaner, mix 1/2 cup ammonia, 2 cups isopropyl rubbing alcohol, 1 tsp. Liquid dish detergent, 3-1/4 quarts of water.

This one doesn't check for Brother brand ink. It asks if I put magenta
into the red slot, but I don't know what happens if I say No. Maybe it's
just a reminder. There are a couple situations when one would want to
use the wrong color.
I can't imagine wanting to use a wrong color. If I did, I would edit
what I wanted to print, rather than fooling around with the printer.
However, the
appellate court upheld the finding that the producers involved breached
their duty of loyalty as employees to Food Lion,
and had trespassed,
awarding a nominal $2 fine.[45]
I'm glad to hear it. I think lying to get a job in a place that is >painting the meat red is okay. (Out of context, this would say
"painting the meat red is okay.)

Can I print or clean with a yellow cartridge where the red should be?
