👋Hi HP support team,

Unfortunately, I am still unable to solve the problem on my own.

I would love to receive some professional advice from the team.

Sincerely,

Most likely the cartridge that you show the picture of is defective and replacing it will resolve your problem.

Thanks repairatrooper for your advise and knowledge-sharing.

I attempted cleaning the parts and new prints seem clean.

Do you know if there is use of waste toner container/cartridge in printer model (HP LaserJet 100 color M175nw)?

If so, how would I go about accessing it?
