HP Color LaserJet MFP M477fdn All-In-One Laser Printer Copier FAX CF377a

Works but leaves a trace/shadows after clearing out a paper jam. I purchased new ink to test it and after doing a self clean the machine got a paper jam and now when printing leaves mark traces on copy(see pics) I’m not sure if that is going to go away after usage for a while or you will need to open it up to clean it and fix the issue.

Printer looks in good shape but will need to be cleaned. Unit was obtained in a electronics auction lot and it could have something else wrong that I did not detect so it’s sold as is. Please view the pictures and let me know if you have any questions. Thank you
