I have a Kenmore 70 series Washer that leaves a lot of lint on my dark clothes. How do I clean this?

I have a Kenmore 70 series Washer that leaves a lot of lint on my dark clothes. Model number for the washer is 110.26722690 (probably made in 1995-1996 time-frame). I see lot more lint when I do not use the dryer. I tried to open the washer to see if I can find the lint trap, but I do not see anything. Some folks say that some model have a filter while others have a self-cleaning system. Can someone help me find the filter if my model has one? Or if it is self cleaning system, how do I clean that and get rid of the lint? Thank you.
