Cause: The fax resolution setting was set to a low resolution, such as Standard. If this did not solve the issue, try the next solution. Solution 2: Make sure the glass is clean Solution: If you are sending a fax from the glass, make a copy to check the quality of the printout. If the quality of the printout is poor, clean the glass. Cause: The glass of the product might have been dirty. If this did not solve the issue, try the next solution. Solution 3: Use the Lighter/Darker setting to darken the original when sending the fax Solution: Make a copy to check the quality of the printout. If the printout is too light, you can darken it by adjusting the Lighter/Darker setting when sending the fax. Cause: The Lighter/Darker setting might have been set too light. If you were sending a faded, washed out, or handwritten fax, or a document with a watermark (such as a red seal or stamp), you can change the Lighter/Darker setting to send the fax darker than the original.
