This can be one of two
Print cartridge (you can do it, replace toner cartridge)
or Fuser (needs to go to doctors)
stop a print half way threw to confirm that it is print cartridge, good chance it is.

there is probably ink on the rollers. get some paper and just keep feeding it till the black marks stop. and RECYCLE the paper that you fed. DO NOT throw it out

This problem is often caused by spilled toner. Open the printer, carefully remove the cartridge, and give it a few bursts of compressed air. Often running several pages or type through will also fix this. If it persists, replace the toner cartridge.
Hope this initial info/idea helps. Let me know for any clarifications.
