Press P-interrupt-C-interrupt and enter test command 14 and Execute to clear your error. Let your machine reboot. If it comes back you have a problem with your fuser. Most likely it's dirt or toner caked on your tempature sensors and they need to be scraped off.

Unplug the Machine, remove the board you installed, re-seat the board,
make sure everything is connected, turn machine back on..

This is what the Manual says:
IMC PWB communication trouble (Timeout)
Check the connectors of the IMC PWB
and MCU PWB.
Check the grounding of the copier.

If you need further help let me know..

Hi there,

Network scanner tool (or NST) comes bundled with the Sharpdesk application. It can be loaded as a standalone but it is bundled software. If you have dealer access to Sharp's website you could download the software from there.
If this is a client of yours you should be selling them another copy of the software as it is no fault of your own that they misplaced the CD plus its extra revenue.
I would love to help you otherwise, but this is copyrighted software.
