Question about Canon imageCLASS D320 All-In-One Laser Printer
This is caused by a rotating part that is contaminated, most likely the drum that transfers the toner to paper.
A new drum or drum cartridge is probably needed.
There is a very remote chance that the high voltage that charges the drum is being modulated but I have seen this once in decades of service.
