Lower Fuser Pressure Roller HP LaserJet 1160 1320 RC1-3630

Rollers tend to wear out at the same rate, often before the fuser needs replacing, 

i.e.

 

Pick-up rollers wear out will give repeated paper jams

Worn separation rollers cause more than one sheet to feed at once

Transfer rollers wear, resulting in inconsistent print quality (uneven printing density, print irregularities, white or black lines, streaked lines, toner specks)
