Customer Question

My Canon MP640 constantly tells me that the inner door is open and then after opening and shutting the door it only prints a portion of the page and then ejects the incomplete page and gives me the same message again. Colour photos now come out with varying levels of colour and lines of no colour. This is with all new ink cartridges installed. I have tried this with Canon Ink Cartridges and generic replacements and the result is the same. I feel like the printer needs compressed air to clean it out?

Hi there and welcome

It does appear something is stuck inside the printer that is tripping a sensor and causing this issue.

First, have you opened it and checked for any scraps of paper stuck inside of it?

Please let me know.
