Why does my Oki B 410dn Printer have vertical white streaks?
Vertical white streaks or faint areas on pages printed by your Oki Printer can occur if the toner is low or not distributing properly, or if the drum is worn out. Try replacing the toner cartridge first. If the problem continues, check the drum and replace it if necessary.
How to fix grey background on Oki B 410dn Printer prints?
If your Oki Printer is producing pages with a gray background, it is likely due to static electricity, often caused by dry environments, which makes toner stick to the background. Try switching to a smoother laser bond paper or using a humidifier to reduce static.
Why are pages curling excessively from my Oki B 410dn Printer?
Excessive curling of pages from your Oki Printer can be due to several factors. Ensure you are printing on the correct side of the paper by turning the paper over in the tray, noting the arrow on the paper package. Also, moisture in the paper from improper storage can cause curling; avoid storing paper in areas of high temperature and humidity and keep it in protective wrapping. High humidity in general can also contribute, so maintain a recommended operating humidity of 20-80%.
