My HP LJ IIIsi toner ran low a couple of days ago, so I put in what I thought was a new cartridge. When I started printing, it had smear streaks all across the page, and from top to bottom.
I looked inside, and did a little cleaning on the soft rubber roller. That seemed to help, but I couldn't get it all to go away.
1. What do I clean that roller with?
2. What's causing that roller to get inked up--a leaky toner cartridge?
Thanks for any help
