Error u052 canon mp550 - PIXMA Canon Office Equipment & Supplies

SOURCE: Canon MP530 U052 Error

The dreaded U052 error means that the 'chip' fitted to the Cartridge is not responding .. Canon (like all printer mfgs) makes all it's profit from selling Ink .. so they fit these chips to try to prevent you refilling or using a 'compatible' replacement cartridge

You have to move the chip from the Canon cartridge to the 'compatible' and (it seems) the chips are particularly sensitive to static / damage .. many people end up blowing the chips during the swap over .. or even when fitting the original genuine cartridges to a brand new unit for the first time ...

If the unit is brand new, take it back and demand a replacement ... if you have just swapped over the chip onto a compatible cartridge, you can try buying a genuine Canon cartridge (which will have a new chip) = hopefully that will do the trick

NB. I have seen some suggestions that canon's have a 'Service Mode' that allows you to disable the cartridge chip checking and allow you to print no matter what .. however I've never found any details ... perhaps some-one else has the details ??

That is a printhead error, sounds like you will need that new printhead.

you wont like what you find. lol .
apparently if you call cannon support they going to tell you its a U052 is a temperature sensor error. and not the print head error. someone musta did some bad programming. lol
try returning the cartridge if its not a canon specific cartridge - and get replacement - try that - but i doubt its going to work - i would call about a new one (print head that is - they will also apparently send you a new print head.) as i have read up on
hope this helped x404x

Testimonial: "Thanks for your quick response - I thought there was a resetting tool available so I can at least remove the message and get printer going."

SOURCE: we have canon pixma mp550

The B200 error is "Printhead Temperature exceeded", What this means that while you were printing some document, either one or more of the printhead ink wells ran out of ink and the printing continued. Printing without ink in the wells will overheat the nozzles and can potentially burn the out. 
If the error will not go away once you have unplugged the printer for at least 5 minutes, then there is the possibility that you have already burnt out the head. Remove the printhead and use a 5x magnification glass to look VERY CLOSE at all of the nozzles to see if you can detect any possible burnt out nozzle. If there are the a new head is mandatory. Just be sure it's worth it - a new printer might be cheaper.

SOURCE: ERROR 6000 ON MY CANON PRINTER MP550

The front panel was open ON MP550 and had been hit by the a recliner. There is a sensor on that front door that detects that it is open. I had to take the front door off, reach in the slot on the left side of the opening, slide the sensor back up, and reinstall the door while holding the sensor up. Error 6000 went away!!!
