Digital BW, The Print

I am having an overspray problem on my old 1160 printer, that is a fine
mist of black ink is being deposited outside the print area.  I remember
someone else had this problem years ago, and was wondering if it can be
fixed, or if that is the beginning of the end for this printer? Printer
is about 3 1/2 years old and has had thousands of prints through it.
