Yep your printer is nearing service time. This involves changing the waste ink pads and resetting it.
you could reset the printer without changing the wate ink pads but you risk damaging it
What i do is take the pads out wash them and replace them.
the waste ink pads are the pads the cartridge rest on whan itsn in neutral position

Go to this link. Wait a few seconds for all the files to load. Select your OS in the box, then wait a few more seconds, and you will see the drivers displayed.
You will need to download and install both the driver and the MP Navigator (under the Software heading). Click on the link and follow the instructions to install.

I tried the other solutions listed here - and no luck. After cleaning the inside of the ADF, like the manual suggested - no change. How are you supposed to do that anyway? Deep cleaning the inside of the machine also has nothing to do with it.
I finally figured out why things that I copied with the ADF had lines/marks on them, but those placed directly on the platen (big glass) were fine. When you copy with the ADF, the copy is not being made from the large glass area. Rather, there is a thin glass area right next to it.
Turns out, there were a couple of smudges (goo) on that thin piece of glass which were creating long vertical lines down every sheet. Cleaned the glass - problem solved!
Gosh, I hope this helps someone else save some time, and frustration.
