had L6-10, replaced the laser unit, made 10 copies. bad CQ, dirty w/ some streaks. checked the process unit & looked ok but when i re-installed everything back it's giving me dark bkground on entire page. i made sure laser unit was in the same position as the old one. also rep Dr, KA1 & KC1. now it's got a new code E7-2 (LSU trouble) it pops up after the fan kicks on and the lamp does its thing. so i reajusted laser unit and reconnected all the cables again. did sim 61-1 for poligon motor and it displayed "ok". now i'm able to make copies but when 10 copies are made all at once, it stretches the image more and more on each additional copy and has fine black lines all across the page going from front to rear. could the LSU be faulty? any help would be greatly appreciated

If lazer part numbers are correct, then i'd be looking at the main board, maybe some static?,
