Hp HP LaserJet 4

Horizontal Lines

I'm getting horizontal lines on the printouts from my HP laser jet 4. It worked fine first thing this morning, and subsequent printouts have had a series of black lines (about 1/8" thick)spaced a few inches apart going all the way up the paper. We checked the fuser and it seems to be fine.
Thank you,
