PIXMA MG5650 prints some lines darker than others

[bradthetechnut]

What is your printer model number and can you upload a photo(s) of what it's doing?

Dear Brad,

Thanks for your message. The model is a Canon Pixma MG5650.

We have Scanned an example of a page as a jpg, which appears below. I can't eliminate the space between, as I tried once and it seemed to destroy the Scan. I hope this works.

Best wishes, Oliver Dickinson

Thanks for uploading image.  I take it what looks like bold print shouldn't be.

There are a few things I would try.

• Use Canon ink cartridges if not already.
• Head cleaning cycle.
• Print nozzle check.
• If nozzle print doesn't turn out, deep cleaning cycle.
• MG5600 series cleaning the print head

Thank you for these. Yes, the bits that look bold represent the problem. I have done a print nozzle check, and been told it did not need cleaning, but will investigate cleaning the print head.

Best wishes, Oliver Dickinson

Ok.  If the print head cleaning thing doesn't turn out, printer may have an electronic problem.  Though yours is not a $50 printer, I had 2 of those that developed electronic problems.

If your printer is in warranty yet, then you're in better luck.

Also, you might be able to access Canon support directly through your Canon account or 1-800-OK-CANON.  They also have a out of warranty printer replacement program that gives discount on new printer if qualified.
