OT 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?

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.

**It is supposed to clean itself periodically, and I have gone away for
3 months and 4 months and it still worked well when I got back. I'm
suprised that the red has gotten clogged.

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.

Online there are good videos about cleaning Brother inkjets
In this one https://youtu.be/6kwe36unBJA he takes an empty cartridge
and fills it with 8 parts windex, 2 parts IPA (isopropyl alcohol), and
he says doing something, running the cleaning routine I suppose, works
great with such a cartridge.
--- I have some old empty cartridges but not a red one. Will the
printer still function if I'm using what was another color instead of
red. Guesses are welcome.

This is another good video https://youtu.be/zbqlxxPka-0 . Here he moves
the carriage to the middle horizontally, stops it by disconnecting the
printer (although in the comments we see that this can also be done by
holding in the red X or the Stop button for a while), folds a paper
towel in the area under the print heads, then moves the carriage above
it, then removes a cartridge and pumps in cleaner through the port. I
haven't ordered them yet, but
https://www.amazon.com/gp/product/B07PPFLKRD/ref=ewc_pr_img_2 are a set
of 2 100ml syringes with 3mm ID hose attached. This seems to be the
right diameter for Brother cartridge connections.

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.

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.

I would assume colour laser printers to be "idiot proof" with either
different keyways to only allow CMYK toners into the correct slots, or
some form of contacts, so that if you insert the wrong toner into a
slot, the printer knows, and will display an error.

For some reason, I thought this was regarding lasers, but I'd expect the
same to be true for inkjets.

No, but you could use refillable cartridges with an auto-reset chip like:

https://www.aliexpress.com/item/1005005104512837.html

and use them with a ready-to-use cleaner like:

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.

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.

As I recall from my many tutorials on how to refill HP printer ink tank
cartridges, they count dots used, not how much is in the tank.

HP is as sleazy as Apple when it comes to setting glue traps for customers.

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 :-)

On this all-in-one printer, MFC-J625DW, I've bought cheap Amazon ink,
and after that brand wasn't for sale, another non-Brother brand, and
it's never complained. Later models may be more picky.

They're right. My computer printer in the 50's only did black and
white. Also it was coal-fired, made the bedroom walls dirty.

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.

We shall see.

Yeah. It cleaned fine for 6 tries, and then it said red was empty, and
I replaced it with a new one. This is my last red one, but I have other
colors.

I don't really know if it's accurate or not. Not when it warns me but
when it's said a color is empty, I've replaced it. Several times each
color and it's never complained about lacking a chip.

I see the difference. I don't know which I would have preferred, but
the one I bought now says there is a paper jamb error even though I
can't find the slightest bit of paper in it.

This one I didn't pick because of how the ink worked but because I found
it on the sidewalk, but it was top of the line at the time. It prints
2-sided, wireless, prints straight from the phone (not that I've ever
done that.)

I also have another that I foudn on the street which will do everything
but print. Wireless, it will scan and send faxes, but that's all.

So now I have 3 printers, one with a paper jamb, one that won't print,
and one that won't print red. Seems like I could combine them into one
good one.

I don't see any metal contacts on the cartridges.

What surprises me is that the cartridges don't move but the printheads
do. There must be very flexible hoses, non-kinking connecting them.

They are pushing somet h ing like that now. Not a liter maybe, but
bigger extrernal ink supplies. I don't print that much.

Years ago a friend gave me a left over printe and while I was carrying
it down the stairs to the basement, I red ink on the carpet. The
current printer sits on something on the bed. I don't know when I did
it but I got a blue inkblot on the green and white sheets. Can't wash
the sheets until I move 100 things off the bed.

I don't want to buy more ink, because the whole printer may have to be
replaced if I can't fix the red.

So I'm going to try and use the second method from my OP, and that
method doesn't use a cartridge at all.

I had looked it up. It has a lot of ingredients. I don't know which
ones make it clean ink better and which make it less good.

I don't know about that. I think maybe "what you mean" is that it's not
an ingredient, or an important one, in the cleaners that are advertised,
or even the ones that are sold. But ammonia itself I had no trouble
finding, 2 quarts for 2 dollars at one supermarket, and a little over 4
dollars at another. Food Lion and Maryland Giant.

I noticed a big difference in the price of windex too. The Giant was a
lot more.

Food Lion otoh, you may recall "In November 1992, two ABC News producers
obtained jobs at Food Lion grocery stores in North and South Carolina by
submitting applications with false references, misrepresenting their
educational and employment experiences on their résumés and omitting
their current employment with the network. ABC broadcasted a report on
“PrimeTime Live” alleging that Food Lion’s meat department at those
stores required employees to engage in unsafe, unhealthy or illegal
practices, including selling old meat that was washed with bleach to
kill odor, [and then dying it red so it looks nice, Micky] selling
cheese that had been gnawed by rats and working off the time clock."
https://www.rcfp.org/journals/news-media-and-law-spring-2012/landmark-food-lion-case/

A little after that time, I bought chicken from them and when I got
home, it smelled bad, the same day. Only time in my life. So for 20
years I haven't bought meat from them, but I relented last June and I
see that they are now about 40% cheaper than 2 or 3 other supermarkets
and I've seen them mark meat down when there are still 3 days left
before the sell-by date, which Food Lion itself determined. Is this
really the result of what hhappened in 1992? Hard to believe.

https://en.wikipedia.org/wiki/Food_Lion#Primetime_Live_controversy
The company responded by suing ABC for fraud, claiming that the ABC
employees misrepresented themselves; for trespassing, because the ABC
employees came on to Food Lion property without permission; and for
breach of duty of loyalty, because the ABC employees videotaped
nonpublic areas of the store and revealed internal company information.
During the court battles between Food Lion and ABC, over 40 hours of
unused footage were released that helped Food Lion's case. In the unused
footage, two undercover producers are seen trying to encourage
violations of company policy; however, employees resisted and correctly
followed sanitary practices.[43]

Food Lion was awarded US$5.5 million by a jury in 1997. The award was
later reduced by a judge to $316,000. The verdict was then largely
overturned by the U.S. Court of Appeals Fourth Circuit in Richmond,
Virginia. According to the court: even though ABC was wrong to do what
they had done, Food Lion was not suing for defamation, but rather for
tort as a way to get around the strict First Amendment standards for
defamation. Food Lion did this because the company was not contesting
the truth of anything ABC reported in the broadcast.[44] 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.)

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.

That site will not open unless you login.

But yes, that's what I use fo the car glass "water", in different
proportions. Or in bottles.

Only that I use distilled water. Or water out of a dehumidifier.

I don't own a color printer these days, but over the years I've owned
a few.

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.

Apparently the purpose is to unclog the head, not printing.

I didn't read every word carefully . Is there a "duty of loyalty" to
employers?

Wow, there is! Among other things, the duty of loyalty includes an
employee's duty not to act or to agree to act during the period of his
employment for persons whose interests conflict with those of the
employer in matters for which the employee is employed. Restatement
(Second) of Agency § 394 .
https://www.wolfbaldwin.com/articles/employment-articles/an-employees-duty-of-loyalty-to-an-employer/
Just a law firm's opinion but i'm sure they're mostly right.

I used to work as a 'consultant" and then a "contractor", as a computer
programmer, and I always felt more loyal to the client than my actual
employer, because the client needed the work, paid for the work, and I
spent much more time with them, and got to like them. It never
happened. and there were no issues, but if there had been, I can see how
easily I would have ratted out my employer to the client. I guess I
would have been liable in a law suit.

A bigger issue might be the public. Again, there were no issues
involving the public, but many jobs have them.

I should read the link above in case I ever go back to work again.

Often they won't print with the *correct* cartridge! ;-) The industry
has managed to 'destroy' the inkjet printer IMHO, I have use inkjets
since my first DeskJet 550C, but found their reliably sucks so badly now
I only use lasers.

My opinion aside, the short answer is 'no'. The color cartridges are
both mechanically keyed and electronically key with their embedded
chips. This will prevent you from inserting for example a CYAN cartridge
in the MAGENTA slot.
