5550 DeskJet 5550 curious error message

Using the correct black ink cartridge (#56) but getting a message that "the black cartridge is not compatible with this printer". I know it's the right cartridge. Have used it many time before. Any ideas? Thanks.

    Thanks Trevham! I am using a mac and took your advice. I replaced the cartridge and that did the trick. I owe you one.

    Got message to replace black ink cartridge because ink was low (it wasn't). I replaced it anyway with the cartridge I've been using for years (from HP). Now all of a sudden I am getting the message that I'm using the wrong black in cartridge, and I can't print! Not happy. . .

    Wild... I suddenly started having the exact same problem. By black ink cartridge is genuine HP, but has been refilled tons of times. My color cartridge is a NuKote knockoff, but has worked fine for a month or so.

    About 5 days ago the printer started kicking out error messages on both of the cartridges. I was able to resist for a couple days by repeatedly taking them out and putting them back in, but now it's completely given up on me.
    I suspected that HP had run a quiet driver update or something on me, but I brushed it off as paranoia. Now I read this, and I'm back to pointing the finger at HP.

    I've been refilling these cartridges for a couple years, and have had to overcome the typical issues by swapping through three cartridges to reset occasionally. But this is something different that's happening now.

    The black cartridge is causing a fault code to be displayed but is not short of ink and is the correct number and has worked before

Do you happen to be getting this on a Mac? I'm wondering if this is the Mac's notification for your cartridge being too out of ink to print. I came across this error today and had to replace the cartridge to fix the problem (mind you with the exact same version, just new).

I have an HP 5550 printer. The Ink Cartridge light continually blinks (and nothing prints) when I have both the colored and black cartridges installed. When I remove the black cartidge, it works fine and...

More than likely you have either a defective 56 (black) cartridge or it's empty. If you have Windows XP you may go to control panel and select printers and then right click to get to properties and preferences. From one of those you can get maintenance and attempt to do a clean and see if that works. If you have a cartridge refiller in your area take the cartridge to them and get it weighed....they'll know if it's empty or not by the weight. If you're lucky enough to have a kitchen scale that weighs in gms then weigh it yourself...if it's empty then it will problem be in the mid 20's vs. mid to upper 30s when it's full. EBAY has lots of 56 cartridges for sale and they will usually work just fine. The tri-color ones are more of a crapshoot.

No matter what 56 black ink jet cartridge I install, including original HP 56 cartridges, my printer tells me that the cartridge is "not compatible" or words to that effect. Is this a problem that is...

You can get the unit serviced because either the motherboard in the unit is broken or the catrige carage is not working.

There is nothing now to self repair unless you can open your notebook and replace the motherboard yourself.

Hope this helps. Any questions just write me back.

Printer has been idle for several weeks.When I came to use it the printing is broken and faded looking.How do I clean the cartridges?

HP Deskjet 5550 Printer.

The deskjet printers should not be kept idle.

At least once in two or three days, you can take one page print out.

This has to be done, otherwise, the inks both Black and colour will get frozened and sometimes it will become dry at the catridge mouth.

Black Ink is 56 and Colour is 57.

Solution :

01. Manually remove both catridges from the printer carefully.

02. Shake the catridges with full force pointing towards ground. You can find out now, that ink is coming out from the catridges which was frozen or dried up.

03. Clean the cartridge drive with a nice cloth and cleaning liquid.

04. Re install both catridges and take a test print out.

05. Recommended to have a service contract with local HP Authroized printer vendor to have a regular maintenance at least once in a month.
