Hi @Vanithalingam,

Thanks for sharing the details. 

Solution one: 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.

Solution two: 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.
• Load the paper print side down in the input tray. Many papers have printing and nonprinting sides, such as photo paper and envelopes. Usually, the smoother side is the "print side," and sometimes the non-print side has a logo of the paper manufacturer on it.
• Do not use wrinkled or curled paper. Use only clean, wrinkle-free paper.
• 
• Use the correct paper type for your project.
• For everyday text documents, plain paper with ColorLok technology works well. Paper with ColorLok technology is industry-standard paper that works well with HP ink.
• 
• For documents with dense printing, such as high contrast graphics or photos, use HP Advanced Photo Paper for best results.
• Some paper might not absorb ink as well as others. If your prints smear easily, make sure you are using a recommended paper.
• Store photo paper in its original packaging inside a resealable plastic bag. Store the paper on a flat surface in a cool, dry place. Load 10-20 sheets of photo paper only when you are ready to print, and then put the unused paper back in the packaging.
• Try using a different paper. This determines if the problem is related to the paper.
• Try to print the document again with the appropriate paper type.
• If these steps resolved the issue, you do not need to continue troubleshooting.
• If the issue persists, continue to the next solution.
