My sharp ar5520 gives error after changing the sensor F2

SOURCE: My Sharp AR-287 Copier is showing F2 error

there Should be 2 additional numbers. F2-??

SOURCE: I have a Sharp AR-507. Error F2-00. How to fix?

It could also be the sponge roller in the toner hopper. The old ones started to deteriorate after a while so sharp modified them.

SOURCE: SHARP ARM 207 ERROR F2 04

Incorrect toner cartridge or has been refilled and gone past its life.
Replace toner

SOURCE: when i power on, it

H4 error is heat roller low temperature, try pressing the "#" key then "Interrupt" key then "C" key then "Interrupt" key to get into simulation mode and enter 14 and press start the follow instructions on screen (should be press ok). This will reset the code and restart the machine. When the machine restarts if the error was a not mechanical the machine should go. If not you have one of two most likely problems; you need to reset the thermal cut-out on top of the fuser unit or the fuser lamp is blown.

Hi,
always "L" code followed by number 1,2,3,4. so if you have L1, L2 or L3 your problem in the optical unit try to remove the copy glass and check the scanner movement by hand. and if the code L4 that mean you have driving machine problem some time this problem cause by toner cartridge so check it .
