L4-03 is a lock of the fusing motor. It's likely you need to have the fuser rebuilt. You can try resetting the error by turning off the main power switch (located behind the front door under a little plastic cover) and back on. It's likely the error will come back. There's a cleaning screen on the lower fuser roller which gets gummed up with toner and sticks to the lower fuser roller causing it to seize and the motor not to be able to turn causing the L4-03.

Sharp does offer a linux driver, look for a cups driver.. Sharp offers drivers for mac, linux, hp output servers, as/400, windows etc... of course this varies on model number...

Some part/ unit (developer, drum, imaging unit, fuser) or something else is
not installed properly or is not plugged into the machine. Check all
assemblies that can be removed from the copier, and make sure they are
installed and plugged in properly.
The 'ch' code will automatically reset when the fault is found.

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
