It's Very Simple

Just Enter in Service Mode of your printer and clean absorbers count.
To enter in SERVICE MODE
1) Power off Printer
2) Push and hold "Resume" button and then push and hold "Power" button
3) Hold the Power button, then release and 2 times press Resume button
4) Led indicators must change
5) Release all buttons
6) Then printer in Service Mode
(If something wrong, repeat 1-6)

To clean absorber counter,
7) Press "Resume" Button 4 Times and after press Power button. It's all! Your absorber count is EMPTY!

In SERVISE MODE you can do several useful things:
To print Service Nozzles test, press "Resume" 1 time and press Power
To print EEPROM data, press Resume 2 times and press Power.

DO NOT press Resume 3 times and POWER. It will reset some EEPROM data settings

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.

During installation , use sharp ar205 developer and sharp ar021 toner cartridge. This shows you did not use developer or used the wrong ones, good luck.
