Canon MP620 feeder problems!

[Jimbot]

My canon MP620 has recently started printing with 10 or so blank white horizontal gaps across the page. It is not low cartridge or clogged print head - the gaps are about 1mm and come in the middle of the printing. I think it is a feeder problem - the feeder moves the paper 1mm too far each time it moves the paper through. The problem happens if I am copying as well as printing from the computer, and in color and black and white. (please see attachment)

I have just resolved the B200 error problem by installing a new print head, and this new problem started straight away.

I have tried the maintenance you can do from the computer, installing up-to-date software, searching forums and google, and the canon technical support and found no solutions!

Please help!!!

If problem also happens with a print job sent from computer than it does not look like feeder problem. B200 is printhead error.
