Question about Konica Minolta Magicolor 4690MF Multifunction Laser Printer

1 Answer

Vertical streaks but only on first 2-3 pages

My Konica Minolta Magicolor 4690MF is exhibiting a very strange problem. Whenever I start to print something on the first 2-3 pages I get 2 or even 3 very ugly vertical bands - streaking with a mix of colors. The streaks are less visible on page 2 compared to page 1, on page 3 they are barely visible. Starting with page 4 the printout is perfect. I can print a 100 page document and except for those first 2-3 pages everything looks great. However if 30 minutes later I print another document the same problem occurs again (first few pages are dirty). Any suggestions as to what could be causing this?

You need to clean the printer. See your manual for instructions. It is probably dust on the laser lens

pleas check transfer belt, and drum unit, probably these lines are caused by drum unit and you have to change it. also you can clean laser glass, what is under the drum unit. if both look fine you can also look at the fusing rollers.

Check the sensor for tray #2. Another remove the tray #2 check for broken acturator and or broken tabs that go into the machine to indicate the printer draw two is closed. Lift the printer off tray two use just one and bypass does that work eliminates the circuit board of the machine.
