Cyan & magenta ink will not flow + yellow ink full but error message says almost empty

Is there any way to get the colors flowing again? I filled some old cartrages with cleaner fluid & ran that through several times. It didn't seem to do the trick. any suggestions?

Re: cyan & magenta ink will not flow + yellow ink full...

(Use new carts for this procedure because it consumes some ink!)

press menu then start mono (blue copy button) then fourtimes arrow up. machine will be in maintenance mode. press 7 then 6 then 4 then start mono (blue). machine will refresh ink within tubes and print head and do some cleaning. when in mantenance mode again press 7 then 6 then 3 then start mono. machine will do a power cleaning. afterwards leave the mode by pressing 9 then 9. Run a quality test print by pressing ink etc.

If you cant see any mag and/or cyan the ph is clogged or dryed out. It has to be replaced then.

If you can see some of the blocks do the power cleaning (7/6/3)again.

BTW: Do use only DYE ink for all brother printers! The pigment ink will clogg the micro filter infront of the nozzels. When running machine with generic ink print a quality test sheet once a week!

One of my cartridges does not work

Start out by running a "nozzle check" in the printer setup screens. If the cyan isn't printing a full pattern, then do a "clean" pass, up to 3 times. If three times doesn't fix the missing color pattern, it's possible that the cart is defective, and isn't flowing ink.

I replaced an ink cartridge because the printer stopped working and showed a message that the old cartridge is empty. However after putting the new one in but the printer still refuses to work and shows...

maybe the cartridge is wrong, release it and clean the electrical contacts, put them again one by one, if notting happen, try this
Solution As the printer operates, it moves ink from the ink cartridges into a printhead reservoir. The printer does not deliver a message when an ink cartridge goes empty, because it still has ink in the reservoir. The printer continues printing until the ink level in the reservoir falls to a first trigger point - then a message appears advising the printer owner to Replace Cartridges Soon . At this point, other cartridges that are empty but have not reached the trigger point are also mentioned in the message, to save trips to the retailer. After the first trigger point, the printer can continue printing until ink levels in the reservoir reach a second trigger point. At the second trigger point there is only enough ink left to perform vital servicing tasks, and a new message appears, saying Ink Cartridges Empty . The options offered depend on the usable inks remaining. If no options are offered, the cartridges indicated must be replaced before printing can continue. The Ink Cartridges Empty options are described in the table below: Ink colors out Option Print mode possible All Cancel None Black


Cyan, Magenta, or Yellow (any or all) Black only Continue with other colors Cyan/Magenta/Yellow mode (composite black)

Text and photo quality will differ from those printed when all colors are available Light Cyan or Light Magenta (either or both) Cyan, Magenta, or Yellow (any or all)

(Black still available) Print with black ink only Grayscale

Serious Color Printer Issues

This is to do with the way in which the cyan, magenta, yellow and black ink is mixed to produce all the colours e.g. to print "red" requires both magenta and yellow ink. Thus, if the magenta ink is not flowing for some reason, for example, the "red" will print out as yellow. So, make sure all your cartridges and nozzles are working properly.

Prints only green predominently

Without knowing what printer you have or what things you have tried I can only guess here. It sounds like you need a new cartridge. A color ink cartridge will have 3 colors of ink for most printers...cyan (blue), magenta (purplish-maroon), and yellow. Depending on what you print it is very possible that you could run out of one of the inks before the others. Printing green can be an indication that you are out of magenta ink. The cyan and yellow inks will combine and look green.

You can remove the cartridge and run a tissue over the printhead and see if you see all 3 colors as a quick test. If you only see cyan and yellow, then the magenta is probably empty or dried up. If you see all 3 colors I would reinsert the cartridge and try printing again. It is possible that the magenta was just clogged and you cleaned it with the tissue. If it still doesn't print all colors your best bet is probably to just get a new ink cartridge.

Ink cartridge lights blinking

That is happening because you have "smart" chips on your cartridges, so even though you know there is still some ink left in the tank, if the chip says stop, the printer will stop printing. There is a way to bypass that and that is by using a re-setter. You can either buy one or ask to re-set your cartridge in a refill shop.
You can also try holding the "resume" button (triangle in circle for about 10 seconds for each cartridge, sometimes doing that resets the cartridges.
Do not refill the magenta and cyan cartridges if they are not empty, you'll just be wasting your money. Better use it to buy a re-setter ;)
Hope that will help!

Misreads ink tanks: says full ones are empty and there are 2 cyans, etc.

I had the same problem -- error message saying two cyan print tanks installed. Nothing helped (including disconnecting power cord). Then found I had an older cyan print tank still in its pack on hand, Installed that. No further problems. Assume this means print tank giving error is part of a faulty batch so am returning to retailer for refund from Canon.
