What are some ways to verbs a laser printer?

I own tried roller cleaning sheets and they made it worse. It is leaving black streaks adjectives over pages.

Answer:
Black streaks may be cause by :

1. Dirty toner cartridge. You can usually check this by removing the videotape and pushing back the cover to do a optical inspection. DO NOT touch the toner cartridge roller.

2. Dirty verbs roller - if you know where this is, you can look at it.

3. Dirty fuser - if you know where on earth this is, you can remove it and do a visul of the roller. BE CAREFUL - FUSERS GET HOT.

4. Just plain ol' dirty printer. Pull out the toner cartridge and look inside the printer. You may see some toner residue that can be cleaned beside paper towels.

sounds similar to you might have dropped toner within it, take out the rag trays, toner cartridges and get the vacuum. dont in actual fact touch the printer with the vacuum attachment.. hoover.
Try a different toner videotape. It could be that the image roller inside of the toner tape is damaged.

Go to www.hp.com and enter your model followed by the keywords "Print defects" surrounded by a search box.

Also be aware of the charging roller which is a foam covered roller. You cannot touch this roller. If you draw from oil from your hand on this roller you may have to replace it. It lies newly underneath the toner cartridge.

Worst suitcase, you may have to replace the fuser if it is worn out.
