I have been having the same problem from my cannon l100.

If you switch off the fax machine for 30min the switch it back on again the fax will resets its self and will clear this error.

Just flip the little key cover open on the right hand side of the machine then press "Data Registration" then press "Set" then press "Set" again this will put you on time & date setting if you press "Set" a third time you can now change the settings using the arrows to step around and the numbers to change the settings. Just press "Set" when finished to save your setting & press "Stop" to exit programming mode.

E100 means that you have laser trouble, probably laser pcb is bad. Replace it.
But also check the laser shutter.
