[WayneSh]

I got a vertical white dots lined on my document no matter it's white or colored pages. I own his unit for about 4 years and only printed less than 3000 pages total. please advise what can be done to fix it. 

Used generic cartridges. Performed cleaning process with the HP smart. And these did not solve the problem.

Hi @WayneSh,

Welcome to the HP Support Community. 

I'd be glad to help you! 

Step 1: Use genuine HP toner cartridges

• HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to the HP anti-counterfeit webpage (in English).
• Purchase replacement cartridges and other supplies from the HP Store or local retailers.

Step 2: Check the paper

• The quality and type of paper can affect the print job. Follow these guidelines to make sure that the paper is appropriate. If it is not, load an appropriate paper type.
• Use paper that is designed for use in HP LaserJet printers. Do not use paper that is designed only for inkjet printers.
• Do not use paper that is too rough. Smoother paper might result in better print quality.
• After loading the appropriate paper in the tray, try to print. If the issue persists, continue to the next step.

Step 3: Check the toner level

• Select your printer control panel display type, and then follow the steps to check your printer's toner level.

• note:
• The toner supply level and the percentage of toner cartridge life remaining provide estimates for planning purposes only. When the toner level is low, consider having a replacement toner cartridge available. You do not need to replace toner cartridges until the print quality becomes unacceptable.
