I've suddenly received an error message on an HP LaserJet Enterprise M725MFP Printer. The message displayed was saying "Communication Lost " in several languages. since then the printer was no longer usable. However, a colleague replaced the formatter and it worked again. So, I would like to know what caused it.

the communication lost error indicates that an error in connection between the formatter and the control occurred. In this case it was caused by a bad formatter (electronics do fail). It can also be caused by a bad cable that connects the two parts or by a bad control panel.
