Hello, and Thank You for choosing JustAnswer.comMy name is ***** ***** I am reviewing your question now, please stand by for 1 or 2 minute for reply.
I am pullilng the technical manual, to check your error message.
5100 is not found in the technical manual.
So, is the 5100 message on the LCD screen on the printer itself? or is that 5100 message on the computer screen?
okay, heres what you need to do.
Take the ink cartridegs OUT of the printer, and then PUT them BACK in.
This is called RESEATING the cartridges.
Its possible one of them, isnt seated all the way, or is not seated properly.
Then see if the message clears.
