Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Is the message on the printer itself?
If so, connecting remotely will not be needed. That is a message about the internal workings of the printer, and does not involve the computer (or its control of the printer) in the least, I am sure.
(The price for remote control for this sort of case, I cannot cite... I have no power whatever to set prices. As an Expert at JustAnswer, I provide help with technical problems.)
Are you using genuine Brother toner supplies? is a question that needs to be asked.
And, is there build-up of toner on the pickup roller? visibly, I mean.
And lastly: Is there an error code number, accompanying the error message? if so, what is the error code, please?
