How's it going.Let me read of your question. Give me a minute.
What OS are you using?
I see, we need to do a cleanup on the printer. Is this OK?
You will usually see problems like this when the toner cartridge transfer roller is either not being cleaned properly or the roller is scratched.
You might try removing the toner cartridge from the printer (turn the power off first!!!) slide the cover open and see if the roller is scratched or you can see a line of toner still on the roller. If the roller looks fine then shake the roller a couple time and insert back into the printer.
You can also check the paper feed path to make sure there is not any deposits of toner causing you this problem.
I've attached a link to a HP document that may help you as well...
