A large area of expected print is missing.
Try printing on recommended media that is dry and fresh out of a ream. Paper can absorb moisture at high humidity, preventing toner from sticking to paper.
Check the cartridge toner level. Replace the cartridge if the toner level is low.
Clear the paper path of any paper debris, stables, or other obstructions.
Check that no obstructions block the laser path above the cartridge.
Check the transfer roll assembly for contamination and wear. Replace the transfer roll, if needed.
Check the left and right-hand transfer roll brackets. Replace them if damaged.
