what have you done if anything?
can you post pics of the issue?
OEM or 3rd party toners?

If all the needed maintenance has been done and that happens on that model you could try:


set it to turn on the ID sensor every 30 copies.
SP2507-01 to 1 and SP2507-02 to 30

That's assuming the machine doesn't need a PM and the developer is not way past due to be replaced

Also could be the start of a failing toner supply motor (hopper) or toner pump
