since you seem to be familiar with the laserwriters, what would most likely cause the printed to get lighter and darker along it's length? i've got one ( personal laserwriter ntr, which i think also uses the cannon engine) that's doing that i'll be fixing in a couple of months (and several other laserwriters for parts or to fix). any help would be greatly appreciated, i've tried a new toner/drum cartridge already and it makes no difference. i had fixed another problem it had and it worked great, until i took it back to my friend and it had a bumpy ride in the car (4 hour trip, bad shocks, it wasn't too clever of me...). i've checked all of the connections of course. i'm suspecting a power supply problem, possibly the high voltage power supply.
