Question about Canon Pixma MP500 All-In-One InkJet Printer
Hi ive got a canon mp500 printer and im having a problem now ive changed offices. all my ink is new and all original canon and the correct numbers, but it says "more than one ink tank of the following colour is installed" and the screen points to the smaller black cartridge. but it needs 2 blacks anyhow a 8 and a 5. so im scratching my head whilst using my old crappy epson. please help, james. p.s - i dont have an instruction book sadly so if i need to press any buttons etc please be gentle with me and indicate where/what colour or shape the button is your references please - sorry for being lame! thanks
I think I have come up with a solution!
When the error happens:
Open the cover and re-seat the cartridge.
Tilt the whole printer forward about 30 degrees or more
Close the cover.
This has worked for me multiple times now. I think there is a small sensor behind the contact chip that detects ink levels and when my printer is flat the level of ink is lower than the sensor, when I tilt the printer the error vanishes because the ink covers the sensor. Though I am not sure why the software in the printer determines that there are duplicate cartridges instead of just a low ink warning.
If you still can't get it try taking a standard pencil eraser and gently rub it over the contacts to clean off any oxidation, also do this to the prongs that contact the chip that are inside the cartridge carrier, They bend easily so do it very lightly.

The problem occurs so regularly that it is clear that there can only be one reason for it:
1. the Canon cartridges work fine for some weeks (1-6!) and then begin to give these error warnings fairly randomly from the point at which they fail;
2. they give the same kind of error warnings - as reported here - through a range of Canon printers;
3. cleaning contacts on the cartridges, or any other cleaning of the contacts in the holder (which admittedly are smeared with ink), makes no difference as the error reports repeat in various randomised forms as reported on these pages and others!;
4. re-installing drivers etc. makes absolutely no difference;
5. the only ‘cure’ is to replace with original cartridges which solves the problem regularly - although some unlucky soul might just get yet another faulty cartridge(s);
6. the ‘good’ chips on these proven cartridges can then even be re-used on non-Canon cartridges;
Sorry - but having tried each and every other logical path it is clear that Canon cartridge failure is the only cause and we should all be writing to the manufacturer and demanding suitable compensation expenses and our time (at least 5-6 hours in my case!) - this is why I have taken the time to list this so you can all cut and paste and send it off with a suitable (polite, I hope) comment.
It has to be said that, cartridges apart, my Canon Pixma MP-830 is brilliant and lives up to the reviews which I read (without a hint of this particular problem!) before buying.

On other sites I've seen that this is a faulty chip in the cartridge. With a new one, it should work. Further, canon will apparently reimburse you for the cartridge.
Finally, I had the same problem, and found that opening and closing, taking out the cartridges, and putting them back in often worked ... for a while. Pretty damn annoying. In retrospect, I wish I'd bought a 730, which doesn't have chips -- fewer problems, and you can use cheaper imitations.

I just cleaned the metal contacts on the cartridge and the prongs inside the printer and it works now.

Amazingly, I cleaned the gold contacts on both my IP6700D cartridge holder and the cartridge with nail varnish remover on a cotton tip, wiped them with the dry end, re-inserted the offending cartridge and hey presto - unbelievable - the contacts didn't even appear dirty so it may be some wax or grease or something. I didn't even need to turn it off and on - it just worked!!!

Had the same error after replacing my black ink om my MP830.(UO71) I Put some Methylated Spirits on a cotton tip and gently cleaned the cartridge chip (allow it to air dry). This fixed my problem!

I get the same error on my ip6700d, I just lift the cover for a sec and put it down and it prints.

Check out canon's website for more details...you can download manuals for their products I think there might have been a bad batch of ink cartridges recently. I ran out of black on my MP F20 all-in-one, installed a new one (always buy Canon cartridges) and all of a sudden my print head wasn't registering. I had to order the part, and when I installed it I was still having problems. Once I finally started to get ink going, it said the cartridge was empty already! Bought a new one today and after much fiddling finally got it printing but I still am not getting any blue out of the color cartridge (also a brand new cartridge). Oh well, I print 99 percent black anyways.

Take out all of the cartriges and the take out the container that holds them. Inside the container in the back are circle color index clean the index with que tips (does not have to be completely clean)install all cartriges and restart printer.
