[SOLVED] Dots/marks on the page even after changing toner cartridge, fuser and transfer roller HP 600 M601

Example sheet

I put in a new maintenance kit and toner cartridge after first receiving this error. Not sure why it's still happening. Thanks.

Those don't look like random dots, they look like portions of letters, may be some stuck paper or label piece., or something on the rollers.

Check the fuser, probably the film is pierced/broken
