To reset the drum light on just about any Sharp AL series copier press the following key's in sequence and as quickly as possible (with 4 seconds for the first 4 keys)
Press "C" then the far left key (exposure mode) then the "C" key then the far left again.
So in other words C, far left, C, far left
Some model's use 2 other initial codes, so you may need to use one of these 2 alternate codes to get your display to go blank. The rest of the procedure is the same.
Alternate codes are: #, * , C, * or pound,star,C,star and also
#, Interupt, C, Interupt
If done correctly the display should go blank.
Then key in 24 as if you were going to make 24 copies.
Now press the "print" button
Now key in 7 as if you were making 7 copies
Now press the print button again.
You should now be getting flashing zero's on the display.
Turn the machine off then on again and your drum light should be gone!
You can usually reset this counter at least once to get twice the life out of your drum unit.
