Issue
Vertical black streaks appear on the output.
Cause and Solution
This section describes how to handle if the streaks appear on the printouts.
Are you using appropriate paper?
- Check usable paper, and replace with appropriate paper.
- If using the appropriate paper still does not solve the problem, change one of the <Special Printing Mode Z>, <Special Printing Mode C>, and <Special Printing Mode D> settings.
- To print from a computer, change the setting for [Special Print Adjustment] in the printer driver.
[Mode 1] has the least effect while [Mode 4] has the most effect. Try each in order starting with [Mode 1]. Increasing the effect makes the print density lighter. Outlines may also be blurred or images may appear somewhat grainy.
Did you just replace the toner cartridge? Have you not used the printer for a long period of time?
- Change the setting for <Special Printing Mode B>.
