Try printing on recommended media that is dry and fresh out of a ream.

Try printing with a different cartridge. Replace the cartridge if necessary.
Check the transfer roll assembly for contamination or wear. Wipe toner and paper dust from the area under the transfer roll. Replace the transfer roll if needed.
Check the charge roll assembly by removing the cartridge and lowering the front door halfway. Two small rolls will drop from the top of the printer. If lines on the charge roll correspond to lines on printed pages, replace the charge roll assembly.
