Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sure the problem must be frustrating. I am sorry to think that it is, and I hope I can provide advice to solve it.
That problem sounds severe, and I am looking up data on the error code you have provided. I will post again in several minutes or so.
Please tell me a few things in addition to what you have already explained:
1. how old is your Lexmark printer?
2. what is the full text of the printhead message, please?
3. does the printer have a touch screen, or is it a model without a touch screen ?
The toner being completely out could affect things, yes.
Could you tell me the error message's text (after trying replacing or replenishing the toner) ?
