code f5 for sharp al2030

There should be a sub code for the E7. Depending on the sub code is what the error exactly is.

Finally tracked down an error code list showing the errors were associated with the CCD and scanner

E7 is a few different things. Are there two more numbers flashing after the E7 appears?

F5 has to do with the copy lamp.

It should be looked at by a technician. It needs to be looked at for the E7 issues.

Could you be more specific? e7-03 is trouble in your laser unit, e7-04 is dirt on your inside white strip which helps your copy lamp find the home position, and e7-05 is trouble with your copy lens.
