Thin lines do not print  Make sure Toner Save mode is off in the control panel of the machine

or the printer driver.

 Change the print resolution.

 If you use a Windows

printer driver, choose Improve Pattern

Printing or Improve Thin Line in Settings in the Basic tab. (See

Settings Dialog in the Software User's Guide.)

Wrinkle

 Change to the recommended type of paper. (See Recommended

paper and print media on page 21.)

 Make sure that the back cover is closed properly.

 Make sure that the two gray levers inside the back cover are in the up

position. When you are using thick paper or envelopes, make sure

the gray levers are in the down position to prevent wrinkling.

 Make sure that the media type settings in the printer driver and in the

machine’s Paper Type menu matches the type of paper you are

using. (See Acceptable paper and other print media on page 21 and

Basic tab in the Software User's Guide.)

Offset image

 Make sure that the media type settings in the printer driver and in the

machine's Paper Type menu matches the type of paper you are

using. (See Acceptable paper and other print media on page 21 and

Basic tab in the Software User's Guide.)

 Make sure that the two gray levers inside the back cover are in the up

position.

 Check the machine’s environment. Conditions such as low humidity

and low temperatures may cause this print quality problem. (See

Choosing a location in the Safety and Legal Booklet.)

 Put in a new drum unit. (See Replacing the drum unit on page 76.)
