hi everybody!

found an abandoned HP Laserjet 1020 in the dumpster. got it home, cleaned it and fitted the toner cartridge. it installed fine, prints fine, except the mess all over the paper (see pic).

now I haven't had to do with printers in at least a decade, but I seem to remember it's something with the thing inside the toner cartrdidge, so replacing the cartrdige should fix it.

can someone confirm this, as I can't really afford to waste money if it's something inside the printer. thank you!

It could be a number of things. There are several rollers the page goes through when printing (including the drum it self). They each have a different diameter. You see that repeating horizontal line/zone across the page? That is telling you which roller it is. In service manuals it would tell you the circumference of each roller so you could narrow down your troubleshooting. See if you can get the service manual and if HP still publishes these numbers for your printer.
