Epson C4100 Jam at A When printing from cold

Problem:

I'm having problems with my C4100. Usually the first page after start up or after it has been in standby for a while. The page jams and it's like the page does not go through the fuser unit (where the powder is baked to the paper)
It's easy to know if there is a jam on the way because it can be heard. The printer sounds different just before it jams. When it spins up to speed the "whining" is very different if it is going to Jam. Error code is Jam A and when I open the printer the page is leaving the photo conductor unit and does not enter the fuser unit. After I clear the page and try again the printer usually sounds normal and prints very well.
The service staff, where I bought the printer, can't find whats wrong and recommend a change of MOBO and more..that does cost but they are not sure if that fixes anything (I feel like a test subject, they try, I pay).
Has anyone experienced this kind of failure? What can be done that does not cost as much as a new printer?? I'm now up to USD 300 and the failure still exists.

Solution(s):

This is a known issue on certain AcuLaser C4100's for which Epson have released a countermeasure. The problem is related to a value in the printer firmware and only realy affects the machine when it is first switched on or has sat idle for a long time whilst powered on.

The fix requires a software tool to interogate the firmware and check a value. If this value is set to a certain figure it requires changing. The same software can change the value to rectify the issue.
