All too often owners of an AIO Canon printer get the dreaded B200 error and other models can suffer the same faith too, and then you’re forced to buy a new print head, so nothing new there but.
What I have found is that these print heads are not in fact broken (Damaged) beyond use, but can be very useful when diagnosing future fatal errors on all Canon printers.
You’re at your wits end because out of the blue your printer wont print when only yesterday it worked fine but today your get this a stupid B200 error or similar message advising you to turn off your printer, replace the head or contact a Service Centre. (Same thing)
When you get a fatal error you don’t know if your printer will work again period, because you can’t test it without buying a new print head and you don’t want to pay for a new head only to find the printer still won’t work. (Expensive mistake this is)
Here’s where it helps if you’ve hung onto that old print head that you were forced to replace not so long ago, because now you have a replacement print head to put back into your printer to get rid of this fatal error that has just appeared.
Depending on its previous damage it may well work properly or not but don’t forget to put some solution of some sort into the ink inlets before installing, even water will do if you have nothing else.
Now the object of this exercise here is not to get this old print head working 100% again (It just might) but to use it as a stop gap so as to allow the EPROM chip to reset itself once again.
This replacement head should fool the EPROM chip so it won’t show anymore fatal errors and once you have printed a few nozzle checks with it, you can then reinstall the previous rejected head and hopefully it will work just like normal again.
I have successfully tried this on two of my printers after fatal errors occurred and I was unable to get the printer working again without having to replace the head immediately.
Now don’t get me wrong here if the nozzles are burned in that head they’ll still be burned out, this exercise will only restore a working head that was declared unusable by the printer and not caused by any physical abuse or damage. (Ink starvation)
Please note only try this with one of YOUR own heads that you had to replace previously and not one from an unknown source, because an old unknown print head may in fact make thing worse by causing damage to your logic board also..
