HP color laserjet 3800 ユーザーズマニュアル

●

If printed colors look wrong when printed, select different colors in the software program or printer
driver.

●

If you are using a reflective overhead projector with the printed transparencies, use a standard
overhead projector instead.

If the printer is operating in excessively humid or dry conditions, verify that the printing environment is
within specifications. See the printer getting started guide for operating-environment specifications.

Make sure that all sheets are cleared from the paper path. See 

.

●

If the printer recently jammed, print two to three pages to clean the printer.

●

If the sheets do not pass through the fuser, which causes image defects on subsequent documents,
print two to three pages to clean the printer. However, if the problem persists, see 

.

Over time, toner and other particles can collect inside the printer. This buildup can cause the following
print-quality problems:

To help reduce toner buildup, always configure the media type in the tray to match the

media type that you are using. Printing on media that is a different type than the configuration
setting can cause excess toner buildup.

●

Marks at even intervals on the printed side of the page

●

Toner that smears easily

●

Toner specs on the page

●

Vertical streaks or bands on the page

To correct these types of problems, clean the printer. See 

Use the built-in print-quality-troubleshooting pages to help diagnose and solve print-quality problems.
