I believe under the aditional funcation screen, you can calibrate the touch screen. Is the screen working at all? Does it look like there is Water on it and you can not wipe it OFF. If so, the display screen is cracked and needs to be replaced.

E-100 is an error of the Laser Beam detect PCB. Either the laser unit is not working or the beam detect PCB is not detecting the beam. You can't see the beam so don't try. Since you are also getting a E-220 which is a Scan Lamp error. Most likely cause is a ribbon cable between the CCD unit and Image Processor PCB. You may need a tech to trouble shoot this problem

The path between the sub hopper and the developing
assembly is clogged with toner.
1.Check the rotation of hopper motor gear. (If rotating, false
detection by the sensor is doubted. Feed the toner to the
developing unit in service mode: CLEAR>ENGIN>TNRINST.)
2.Replace the Developing Assembly Toner Sensor (TS1).
3.Replace the Sub Hopper Toner Sensor (TS2).
4.Replace the DC Controller PCB (PCB4).
