My prints have about a 2 inch wide streak, in color or gray scale.Installed new maintenance kit. The Cleaning Page has almost a solid yellow stripe and the Light Stripes Test page has many incomplete or or missing stripes for all the colors within that two inch area (apr. area is 213 - 279 jets). Unable to clear using basic or advanced test procedures. The printer has run 61,000 pges in its lifetime. Any suggestions would be appreciated.
