The F2-04 error code you are getting is that you are using the wrong toner.It may be form sharp,but it toner chips is different.Only the chips swapping at the toner back can help you.

CH - open cover in the paper feed area
CH blinking - Dev unit is not properly installed
For the 'CH' check the covers and make sure all covers are closed properly.
For the 'Blinking CH' take the dev. Unit open and the reinstall unit properly.
Pls rate – thank you

SOURCE: Sharp AR-285 Error Code
A U2-00 is an internal error code from the main processing board's EEPROM (the chip that stores your configuration choices, the copier's serial number, etc.) It can be a faulty EEPROM but most likely the copier took a power hit/glitch and the fault needs to be reset.
To clear the fault make sure the copier is in Copy mode, then press the 'P' key, then the 'Interrupt' key, then the Clear (C) key, then the 'Interrupt' key. This will enter the machine into simulation mode.
Now enter the number 16 and press start. The machine may also ask you to confirm your choice or you may have an 'execute' key on the LCD screen.
Once the fault has been cleared the machine should reboot. If it doesn't, press the 'CA' (clear all) button and the machine should reboot.
If the U2 code persists, you need to call a repair technician to facilitate repairs.

That is a problem with the laser.
There is a glass down in the drum/toner area that you can remove and clean .
You can also try, pressing p*c*, which is #*C* and press 14 first and follow the fault clear procedure, then 15, 16 and 17, press clear a couple of times and the machine will reset. If that does not resolve the problem, there is a motor in the laser unit that has a motor with small mirrors attached. That is the most likely part failure.
