Sharp AR-5127, the error code U2-40

The heating element or the thermal fuse in the fuser unit has failed. Try pressing clear,interupt, 0, interupt, 1,4, the blue copy button to reset it.

This means that the cartridge's sensor is miscommunicating with the copier memory thus the code U2 -40. You should clean the inner sensor connector and the toner sensor of the spilled toner by low blower. Perform this code ;# , interrupt , C, Interrupt keys in that order and press 16 then Print key and the code will be cleared.

all action bloked code: L6-10
please healp me

ERROR CODE U2-4 COULD BE RELATED TO THE MEMORY BATTERY BEING DEAD ON TEH MAIN BOSRD IF IT IS AN OLD MACHINE SO YOU COULD CHECK THSI OR REPLACE AND TRY WITH NEW

Sharp Fuser
H2-0 Fusing unit temperature error
H4-0 The fusing unit doesn't heat up.
***ALWAYS DISCONNECT POWER WHEN WORKING ON MACHINE***
You have to reset fuser errors with simulation 14. Push P * C * then 14 then Start (the button you use to make copies) and it should reset the code. If not then replace the fuser.
SM 5-1 should turn the lamp on. If lamp blinks on and off it is the thermistor, if it does not it is the lamp, but check the contacts on the lamp/fuser -- they have been known to erode.
Also check thermal fuse, if defective replace.

Unplug the Machine, remove the board you installed, re-seat the board,
make sure everything is connected, turn machine back on..

This is what the Manual says:
IMC PWB communication trouble (Timeout)
Check the connectors of the IMC PWB
and MCU PWB.
Check the grounding of the copier.
