hi guys.

Anyone found out what the formatter board issues are for the 4100 l have had several of these machine which will not run through set up, switch machine on and display glows on but will not run through memory check etc so although the light is on nothing is displayed . l know it is the formatter board but l am, fed up with having to change them for what may be a small part requiring replacement. Any ideas would be appreciated.

I do not think the board is repairable. You could remove from the frame and try the baking method. Most times if no memory count it could be the firmware/memory chip or the slot. Correct slot needs to be used for the firmware.

Do the printers have jetdirect cards in them?
If so power down the printer and remove the jetdirect cards, then power up the printer.
Let us know what happens.
