Operating System: Microsoft Windows 10 (64-bit)

I think I posted this originally in the wrong area. We are a small museum. We received our new HP Color Laserjet Pro MFP 4301 fdw printer this morning. We got everything installed properly and then I set out to test various functions. When I copied 2 side to 2 side two wide black bars appeared on page two. Apparently, this is a known issue that was discussed in a thread I can no longer find. Apparently, there are separate scanners that are used when duplexing. I'm very disappointed with this situation. The unit works fine, other than this huge problem. How do I deal with this issue?

The second scanner is mounted on the lid of the ADF,  If you lift the lid as if you were going to copy from the flat glass, the left side of the lid is where the second scanner is.  We have sold a lot of these units and have not had this complaint so I am not sure how wide spread it is. Make sure that upper glass is clean and there is no debris. In some cases, a factory reset will clear issues if it is not caused by debris on the glass.

Barring that, specs for this unit state onsite warranty. Create a case and get a tech dispatched
