GX4020 Auto Duplex Printing Paper Jam

When auto duplex printing, a sheet will randomly be ejected from the printer instead of being pulled back in after drying. The printer interprets this as a paper jam. It generally happens once while printing a multipage duplex document.

Hi,

You can try cleaning the ADF by using the steps HERE. If the cleaning do not resolve the issue, I recommend reaching out to Canon support for real time support with this issue. You will need to register your Canon gear HERE to access additional support options.

We look forward to hearing from you.

Paper does not pass through the ADF when printing.
The printer is new and does not yet have 200 sheets through it.
