Upon startup (Sharp AL-800) I keep getting an E-7 Error Code. Just prior to this problem I was attempting to change the exposure adjustment setting and may have pushed too many buttons (or the wrong ones). How can I reset my printer to factory settings. Help will be most appreciated Thank you, ESB

Exposure lamp error.

The H4 code indicates the fuser may have blown the thermistor. It also could be a false error code. Try this series to clear the error and if it returns, then you'll know for sure the fuser is the culprit. To reset press the following buttons:

1. Press this sequence: CLR-Exposure-CLR-Exposure
2. The display will go blank
3. enter "14", press "PRNT"
4. Press "CLR" several times to exit.

Give that a try and good luck.

You can reset this indicator by pressing these keys in sequence:
Press "C" then press "Exposure Mode" then "C" again then "Exposure Mode" again.
Note that the Exposure Mode key is the far left key on the panel.
One you press these 4 keys in sequence the display should go blank. Then key in 24 as if to make 24 copies. Then press Print (Green Button)
Then key in 7 as if to make 7 copies.
Press print again. You should now get flashing 000.
Turn machine off then back on and the light should be gone.
Here it is in a short version:
C, far left, C, far left, 24, print, 7, print,
then power off and back on.

H3 is a heater/fuser problem. Try to reset it by SIM 14. Press Clear , auto exposure, Clear and auto exposure and press copy key. check if H3 has been reset and LED is back to "00".

You should have on the right side of the display panel a "C" key and on the far left side your "light" exposure key.

Press c-exposure-c-exposure the scree should go blank. using your key pad make the display show 24 then press your copy key. then make it show 7 the press your copy key. Press the C or CA key until the copier resets. The light should have gone off.

if it is printing an all black page, the charging corona sounds like it is broken. try replacing the drum unit.
