Below are the F2 errors and causes for Sharp AR-M160

"F2-31" Image density sensor fault
"F2-32" Drum mark sensor fault
"F2-33" Grid voltage correction problem
"F2-35" Grid voltage correction problem
"F2-37" Drum mark sensor fault

Cause : CRUM chip defect OR Improper developing unit
Check and remedy : As you have already replaced the tonner, we can suggest Replace the CRUM chip,Replace the developing unit

when you install developer you must enter code 25-2 and wait for about 3 minutes to turn motor and DV unit and copier will scence ATC sensor ,then turn off and 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.

there Should be 2 additional numbers. F2-??

WHEN F2 FLASHES JUST PRESS START KEY U WILL RECEIVE A SUB CODE.IF SUB CODE IS 02 THIS IS TONER SUPPLY PROBLEM IF 04 THIS IS DATA PROBLEM LIKE AS IDENTIFICATION PROBLEM MODEL ERROR TYPE ERROR.BYMIAN AKHLAQ

Hi i think the problem code for f2 problem is to enter this code pressing * interrupt CA interrupt then the light will go of then you enter 80 then press copy and 1 copy.
