Hello, I’m Nathan, and I’ll be assisting you today.

Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.

Unfortunately this symptom indicates a hardware problem,

specifically, it is the result of a bad printhead or the logic board that controls it. If you've replaced the head once already, that would point to the logic board having failed, though these printheads are all old stock and often bad right out of the box too.

The head is a "wear item" that fails with age/use. As this is a 2009 model printer, it is well past its 3 year service life, so this type of failure is not surprising.

There is one step you can take here, to clean and reset the system, but it is very unlikely to help. 99.9% of the time, this does come down to a hardware fault. These lexmarks are widely regarded as the worst printers ever made, they were very poorly designed and built and have very high failure rates. They were so bad that lexmark nearly went bankrupt supporting all the warranty claims, and stopped making inkjets entirely shortly after this model.

While it can be fixed, it is not worthwhile to do so. You would have to, at a minimum, replace the printhead again, which costs about $90, A logic board would run you $200-250. For $80-100 you can replace the entire machine with a brand new model, with current technology and a fresh warranty, which makes more sense than buying the new part for an older printer. I would also seek to return that newly purchased printhead, that alone will pay for a new machine.

Depending how you'd like to proceed, I can advise on the cleaning/reset steps if you wish to try, help with finding parts, finding a local repair shop, or recommending replacement options for you. Just let me know.

Best regards, ***** ***** for the news,
