Canon ImageClass mf743cdw horizontal white lines on scan after firmware update

Like subject says, my scans are now showing up with uniform white horizontal lines all along the document since I updated the firmware. The problem is not on my computer driver as this happens also if I use a USB stick directly on the scanner. The device is not heavily used, and was used for scanning documents shortly before the update and this was not an issue.

 

Also, is there a Canon support phone number? Or is this forum the only kind of support offered by Canon?

Thank you
