Question about Sharp Office Equipment & Supplies
You need to firmly push upwards on the door handle until it snaps upwards, then you can simply pull in straight out.
If the handle was loose, you can tighten a screw inside the handle.
To replace the handle, line-up the screw with the slot in the clip that's on the door, push in, and then slide the handle downwards.

Use some air in a can to clean by the fan and all areas that you can reach. Unplug and let cool for 10 minuets. Make sure you have it on a flat surface so the unit can breath.

I think two of the codes may be related, in that case replacing the mainboard located on the left rear side of the machine won't help.
To start L-1 is not necessarily the scanner lock. It just indicate feeding did not complete. It can be caused by a fault or misplacement of the optical group, or by a problem with the scanner position sensor.
CH is door open, and may have been incidental.
error F-5 is copy lamp lightning abnormality. When the lamp is working, this is a very unusual fault. The lamp may have low intensity or intensity too high.
This would be a difficult case to troubleshoot. The tech will probably read error codes again, then decide to change lamp or sensor, or test the lamp inverter with an oscilloscope.
Naturally it can also be the mainboard, but if it keeps returning codes related to optical group, then it is unlikely the main pcb.
This may be a difficult repair.
Better ordering parts from an authorized distributor: Sharp Authorized Parts Distributors.

Sounds like the transformer on the power board is going bad.
