RESPECTED USTAAD JEE- AT FIRST PLEASE START THE FAULT FINDING FROM TRAY
OPEN/CLOSE CIRCUIT.CHECK THE ALL VOLTAGE OF TRAY OPEN/CLOSE MOTOR CONTROL IC.
IF ALL VOLTAGES ARE OK THEN CHEK THE PULSE FOR MOTOR CONTROL IC FROM MAIN OR
SYSTEM CONTROL IC. CHEK THE ALL PARTS FOR HEAT UP.SEE ALL ELECTROLYTIC CAPCITORS
ALSO. CHECK THE ALL JACKS FROM MECHANISM TO BOARD & ALL SWITCHES IN MECHANISM.
CLEAN THE MOTORS WITH PETROL (WITHOUT MOBIL OIL) & CHECK THE MOTORS WITH ELIMINATOR
AFTER DISCONNECT FROM CIRCUIT. CHECK IF ANY SUPPLY VOLTAGE DROPPED.
