    This response is a little helpful -- I can see the flag in the bump and it seems stuck there in spite of being nearly full.  Very frustrating -- I's love to print in just black right now instead of deal with this.

    we had a power outage and after the power came back on my printer says "unsupported ink cart. U059 Blk."
    I've removed the cartridge and cleaned the printer head, and still nothing.

Not a cleanable type head, filiment gets burnt, when ink is not around it when printing is done. Ie dodgy ink blocks lines or has air in it and has permanently stuffed the print head, fix on brothers is replace head, cost excessive.,..time for the bin and the newfound wisdom that inks aint just inks.

Ink empy or no inks is read in ink well compartment via a black flag in ink cartridge that must be up and floating as not to obstuct photocell in well area.. check the rectangler bump in rear middle of cartridge. All cartridges must have flags up ie not empty, seeing ink does not indicate a cartridge with ink, a little is always left to prevent air entering system, hence machine calling out no innk cartridge to prevent damage...

"wrong cartridge"- Printer is giving us a "wrong


Hi Sherri

I am having the same problem with my MP780 mine started doing the same thingafter deciding to use Calidad inks the large black ink leaked into the yellowink (stick to canon inks).

What I have done so far with no success -
Replaced the ink cartridges with new ones supplied by Calidad, still the sameproblem.
Removed and cleaned the print heads manually and to my surprize after soakingin warm water and multiple cleanings for over 1hr black ink is still coming outof the yellow ink head.
I still get the same message after all I have tried...

One thing I did manage to do is prime the yellow ink and got it flowing throughthe head again but it's still mixed with black... I wonder if you may have runout of magenta and dried the head...

Try priming the magenta ink by removing the head (don't touch or wet the metalcontacts at the rear, the ink heads are on the bottom) place on a clean lintfree cloth (or I just used damp tissues then dry tissues) you should get onelong black strip and two cyan, two magenta and two yellow strips on the tissue,if you do not then try priming by replacing the magenta cartridge and gentlypumping the cartridge up and down repeat until you get the ink flowing.

Replace the head and cartridges, press ok, turn the printer off then reset.

Let me know if it works or if you come up with another solution that works as Iam still trying to figure out how to fix mine.

Good luck

Brother MF 5440CN USB Printer won't print. Says "Ink Empty Cyn" and then "Ink Empty Yellow" Replace Ink There is ink in the cartridges.


While there may be ink in the cartidges, your printer is getting a signal from the cartidge that it's near empty. There is no real workaround for this; you just have to replace the cartridge(s). If you use a LOT of ink, you might consider installing a CIS (continuous ink system) now made for most printers. You will save a lot of money over time.

What you describe is typical.

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

AND

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

I haxe recently purchased a brand new canon mp530 that is still under warranty.I don't allways have the problem but often enough for it to be one.Adout 90% of the times I try to print I get an error...


I notice that you saw error message 'check ink c'. This means the printer want you to observe cyan ink cartridge. so,what happen before this message appears?. Please make sure that cyan ink is not empty. if you are sure the ink not empty,then remove cyan ink and reinstall it,else try dry clean ink cartridge contact or you may use contact cleaner before reinstall it. if you have have another cyan ink cartridge that is in good condition,compare it. if this works,means cyan ink cartridge is faulty then you need to replace with the new one. but if the problem still persist,it may caused by carriage unit or logic board problem.

HP all-in-one not printing cyan color


Place a soft clean tissue paper over the cartridge print head and leave for about eight minutes. You can secure it with the aid of a rubber band. It should be held firm ok. If the tissue paper is not dampened by ink then the cartridge would have gone bad or the ink dried. You also know that they have expiry date and could go bad while yet in the packaging b/c it has expired. Good luck
