First, you need to try update the latest microsoft office patch file from microsoft or you can open the MS Word, go to "HELP" menu select the update MS Word or related. Try the latest patch file first. You also can try windows update and select custom update, see their list have this problem solution or not. Second, you need to go to HP website download latest driver for LJ1020 and suitable use on Vista. Lastly, if still not solve the problem, you need this problem/issue to microsoft, ask their solutions. Kent

This a very recent model. Try replacing the toner cartridge.

Had the same problem. Changed cartridge. Still didn't work. I suggest taking out cartridge and examining inside of printer carefully. I found a piece of balloon and a hair tie (aargh!, my kids). Works now.
Just wanted to post this as one more thing to check before junking the printer or spending money on HP support.
