What to do if my Oki C9650hdn Printer has vertical white lines on the printed page?
- JJames PottsSep 2, 2025
Vertical white lines on your Oki Printer prints can be caused by a dirty LED head, in that case wipe the LED head with a LED lens cleaner or with a soft cloth. Another cause can be low toner, so replace the toner cartridge. Also, foreign materials may be present in the image drum, so replace the image drum cartridge. Finally, the light-shielding film of the image drum cartridge may be dirty; wipe the film with a LED lens cleaner or with a soft cloth.
