Sharp MX-M850 showing L4-55 after few copies

[TUNDE OLANIRAN]

please i need technical assistance. i am currently working on a MX-M850 copier. This machine is showing L4-55 ERROR CODE. I have checked all the fans but i cannot ascertain which fan is faulty. This error code comes up after 5-10 copies. Please what can i do? which particular fan do i need to replace?

Fan CFM_TR Check it in sim 6-2. If it happens only after a few copies, it will probably run fine in the sim, but it has a problem. Have you tried replacing it?
