Recommendation
 Make sure that you use paper that meets our specifications. A rough surfaced
paper or thick print media can cause problems.
 Make sure that you choose the correct media type in the printer driver.
 Make sure that a torn piece of paper is not stuck inside the machine blocking the
scanner.
 The problem may disappear by itself. Print multiple pages to clear this problem,
especially if the machine has not been used for a long time.
 The drum unit may be damaged. Put in a new drum unit. See Replacing the drum
unit on page 79.
 Clean the primary corona wire in the drum unit. See Cleaning the corona wire
on page 85.
 The drum unit may be damaged. Put in a new drum unit. See Replacing the drum
unit on page 79.
 Check the machine's environment. Conditions such as high humidity and high
temperatures may cause this print quality problem.
If the problem is not solved after printing a few pages, put in a new drum unit. (See

Replacing the drum unit on page 79.)
