I Have a Sharp Imager AR-M208N copier, I lost the account number and I 'd like to reset it to manufacturer default setting. please, can you help me ?

SOURCE: Lost key operator code for Sharp Copier AR-M207.

The default is 00000

Simulation 22 - 07 will display the Key operator code.

Perform the following procedure to enter the simulation mode.
"#" key -> “*“ (star) key -> "C" key -> “*“ (star) key (do this in quick sequence order, the display should change, then enter below)

Main code {22} ->
(Green Copy Button) Start key ->
Sub code {07} ->
(Green Copy Button)Start key

Press the "CA" button to go back to Copy mode.

Hallow, this is a problem with the exposure lamp on the document glass which is not working or if it is lighting, it is not sensing the white mark on the cover which is above it.
Remedy
Please check if the cover that locks the glass is well screwed or present.
Check if the copy lamp is lighting and replace with a working one.
Check if its cable is not disconnected on its power board located beneath it.
Replace the main board of the machine.
Nb use that sequence to solve your problem and good luck.
