Canon MX870 B200 error, how to use scan only?

[g6381646]

I have Canon MX870 which I only use it for scan.

When I'm turning the printer on at the booting process it give me B200 error and STOP to work completely.

I have to open and close cartridge door couple times at the startup to can skip the B200 error and be able to use the scanner.

I know the problem is related to cartridge or printhead or something about printing.

I only use this machine for scanning and i don't need to print at all.

How I can disable or disconnect the printing component on this machine to be able to use just the scanner?
or at least disable the printer diagnostic at the start up?

Hi g6381646,

We do not have instructions for disabling the printer diagnostic at startup or disconnecting the printing component of the printer; the printer will require servicing to resolve the error.  Please call or email us using one of the methods on the Contact Us page to obtain your servicing options.
