Question about Xerox Phaser 8400 Laser Printer
Dark streaks are an indication of "burned" or overheated ink. This will occur when the printer sets for a long period of time and nothing is printed. The problem will usually disappear after 50 pages or so, unless the printhead is damaged.
If the print remains dark, the printhead will need replaced.
(Dark print can also be caused by using Non-Xerox ink)

Inspect where the dark streaks are on the television. If the streaks occur at the same place on the top and bottom of the screen, they are due to the formatting of a movie or television show you are watching. This is normal. Also, if the streaks appear on the left and right of the screen, they are due to the show being filmed in full-screen instead of wide-screen. This also is normal.
Change the input setting so you are viewing the contents of a different device. If the dark streaks are gone, you know they are due to the device connected to it. However, if the dark streaks remains no matter what input the TV is connected to, the problem lies with the television.
