New Toner cartridge prints Black on left side of paper.

[Lyon27]

A brand new toner cartridge was install in a LaserJet Pro M15w and the left side of the paper is completely black while the text is printed well enough on the right hand side of the paper.  Is the cartridge defective?  If not, what action can be taken to address the issue?

Hi @Lyon27,

Welcome to the HP Support Community. 

I'd be glad to help you! 

I understand that you are having issues with the print quality 

Step 1: Use a genuine HP toner cartridge

• 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.
• Print another page. If using a genuine HP toner cartridge did not resolve the issue, continue to the next step.

Step 2: Check the paper

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

Step 3: Check the toner level

Open the printer software, and then check the estimated toner remaining.

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.
