Canon MP730 - error: wrong cartridge

[Lokalaskurar]

Righty then, methinks I gots here an olde Canon MP730 (know). It's about 8 years old, and I'm tasked with getting it back up and running. It worked perfectly fine right until yesterday - when all of a sudden, a wild Error appeared.

First things first; I do not have to actually fix it. If some component is permanently broken, fine!, as long as I know why it's broken, and which component, I'm satisfied.

Symptoms:
1. I can (and do) access 'Print' and I print a document, just like any printer.
Document is being sent to s-pool.
2. Says on computer that 'There has been an error!'
3. [Looks over at printer] eq. to POST code has appeared:

"WRONG CARTRIDGE"

I always have a load of different cartridges laying around. So I swap them all for the recommended genuine OEM Canon cartridges, just like new.

"WRONG CARTRIDGE"

I'm puzzled. So what should/can I do?

I am very interested in hearing some TechSpot-members' thoughts.

Also, I'm translating the error message, there is a chance that those who coded the printer in my language did so very badly (not uncommon...) - e.g. there is a possibility that the error message is actually supposed to be "Wrong Cassette."


My goal:
Preferably, get the printer back up and running.
Secondarily, if unfixable, sit back and enjoy the error-reading on TechSpot .

The printer has never been cleaned - so maybe I have to change the ink depository if there is one/some. (pardon for poor translation from my native tounge ).

Ok, so I've reset (something) after I've changed the ink cartridges. Now it will print, but only the CMY, not CMYK that is.

What will I have to do in order to get the black ink cartridge working?

Edit:
Don't be shy when it comes to mentioning service commands, I know my specific printer's "Service Mode"-code.

Edit 2:
The printer can copy just like in the old days, but it still cannot print in black.

The following may work: remove all the ink supplies. Remove the printhead and soak it for about 5 minutes in 0.5" of very hot water. Gently blot the printhead on a soft damp paper towel to remove the excess water, then replace in the printer and then reinstall the ink supplies.

Great, I also thought of this actually. I'm trying it now.

And if it breaks, don't worry, I've had a good time with it (like 8 years)!

Edit1:
Haha! The water turned pitch-black! :haha: , like HTML #22222!

Edit2:
Hm... it actually turned more like #330033 when poured out. Now, I can tell that the printer head really needed a bath just from looking at the resulting water-colour.

Let's dry it and snap it into the printer, then.

#snap#

Ok, let's reset the Ink Count... Menu-3-Copy-'Pound sign'

Shucks... still no results... a well, can't blame a man for trying!


Any other suggestions?

check to see if the metal contacts that make contact with the print cartridge are clean if not i recommend using some rubbing achohal and a cotton swab to try to clean the contacts.

 

[Lokalaskurar]

Checked them all right, perfectly clean, not even a fatty fingerprint. I even kept the contacts (the entire circuit board) out of the water previously.

Wondering if you ever got this resolved - I have a similar problem and looking for advice/expertise ...

Printing went horrible (some perfect, some blank lines, some overwritten lines, etc.) - looks like verical problem, although far left and right tended to print well. Tried alignments, cleaning, nozzle check, etc. - no fix. Removed print head to clean for first time (~730 printed pages have been through this thing) - lots of gummed up ink removed - very carefully. Put cartridge back in and now I have "Wrong cartridge" coming up. Have tried recleaning print head and electrical contacts multiple time and had no luck.

Any and all ideas welcome. And if I must buy a new print head and sourcing ideas would also be appreciated (I'm in Canada).

Your reference to wrong cassette makes me think that there might be a problem with the paper feed perhaps? Or maybe the PC thinks the paper is in a different place to where it actually is - or even the wrong sort of paper?

 

[gartht]

It definitely refers to the print head / tanks - with print head removed it says "No cartridge" ...

Yeah, in my case I actually had to replace the 'cartridge head' (or whatever it's called in English). The cassette which holds the ink cartridges anyway.

But in your case, I think you've had a whole lot of luck which I didn't.

Printing went horrible (some perfect, some blank lines, some overwritten lines, etc.) - looks like verical problem, although far left and right tended to print well. Tried alignments, cleaning, nozzle check, etc. - no fix. Removed print head to clean for first time (~730 printed pages have been through this thing) - lots of gummed up ink removed - very carefully.

The million dollar question: have you reset your printer ink count? Some printers need that.

I know that the MP730 model need to be reset all the time every time something happens. Even if I even forgot to close the 'cassette' latch, it needed a full reset.

I know that my particular printer's code to access the service setting was Menu-3-Copy-'Pound sign'. Whether there is a 'Canadian edition' or not (probably because of the built-in modem) -- I am not familiar with. But if there is, the code for accessing the service settings is probably not the same as mine.

So my idea: (if you have a MP730...) reset the ink count. It can be done from the service settings, and there are some very good explanations online on how to do so. First: you'll need your code for accessing the service settings. Start from there.
