I have a Canon Pixma MG5250 Printer which I have been using

Resolved Question:

I have a Canon Pixma MG5250 Printer which I have been using successfully on WiFi time. Recently I used Mackeeper to cleanup my Mac and since then an error message 300 'Unable to connect to computer' has been showing and no printing. This error code is not mentioned in the User Guide?
I have reset from the printer keypad the access code, IP address and the blue light is on signifying WiFi connection but still the error message and no printing remains.
Can you help please?

Please tell me did you find out the meaning of the error message '300.etc' It is not mentioned in the literature or on the Canon web site?

Not from any literature as it is not documented, but I have seen the error code many times problem, so have worked out how to fix it.
