Question about Sharp AL 1631 Copier
Your copy lamp is faulty or scanner drive is not moving. Check the lamp and replace if not lighting.
If its the scanner, unlock the scanner lock above the paper exit tray.

L1 or L1-00 indicates Scanner movement failure. The scanner is the part under the glass that lights up and moves back and forth. So if you lift up the feeder so you can see the glass, turn the machine off for a few seconds then back on. Watch the movement of the scanner. It should move right and inch or two then back to the left. If all goes well the copier should come to ready. Lay a piece of paper on the glass and press the print button to watch the scanner movement. If it binds up or does not scan correctly there are 2 possibilities.
1) your scanner lock is engaged and is preventing the scanner from moving. Check the clear plastic dial located under the far left upper side of the copier, near where the paper exits the machine. Make sure it is in the unlocked position.
2) Your scanner rail is dirty and dry. This rail can be seen under the glass towards the back of the copier. The scanner rides on this rail. It is very common for these to get dirty and for the grease to dry up causing the scanner to freeze up on the rail. The glass must be removed and the rail cleaned and lubricated.
Just power off then on the copier to reset.

L1:Indicates that the Main PWB sensed that the carriage did not leave home after power up or after start is pressed
You may have a bad scan motor, Fuses do blow on those.
Also check for the lamp carriage binding on something.
But as the fault states, the machine is not seeing the lamp moving forward .

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.
