SOURCE: Kyocera KM 3050 - error C3300
Error C3300 is a CCD Automatic Gain Control issue.
It could be poor contact in the connector terminals from the SHD PWB to the CCD PWB.
It is more likely a defective exposure lamp or inverter board that powers the lamp.
Try lifting up the Document feeder so you can see the optics frame through the platen glass and turning off and then on, the main power switch to see if the green exposure lamp illuminates.
A better, but more complicated way to check the lamp is to enter the service mode and run the exposure lamp test simulation. I will outline this procedure below. BE SURE NOT TO MESS WITH OTHER THINGS IN SERVICE MODE OR YOU COULD RENDER YOUR UNIT COMPLETELY UNUSABLE.
To Enter Service Mode:
Hit the "Status" button
Hit the following sequence on the numerical keypad:
1 0 8 7 1 0 8 7
You should be in service mode.
Use U601 by typing 6 0 1 and then "Start"
U601: Turning the exposure lamps on
Description: Turns the exposure lamp on.
Purpose: To check the exposure lamp.
CCD: Main Exposure Lamp
CID: Document Processor Exposure Lamp (inside the feeder)
1. Press the start key.
2. Select the item.
3. Press the start key. The selected lamp lights.
4. To turn the exposure lamp off, press the stop key.
Press the stop key. The screen for selecting a maintenance item No. is displayed.
After checking the lamp(s) operation hit "reset" a few times to back out where you can type 0 0 1 "Start" to Exit Service Mode.

SOURCE: KYOCERA CS-1820 ERROR CODE C7990
Apologies for the late reply. This is a waste toner full problem. Pull out the process unit (in case you don't know, it's the big black unit where you fit your toner into, also the one that you need to remove to check for paper jams. Turn it around so that the side where the toner fits is furthest away from you. Now on the side closest to you, on both the left and right hand side are two small covers, each fastened with 1 screw, hidden in deep holes. Remove these screws and covers, and empty the toner inside.
Be advised that this is a very messy job. Also, after you've removed these covers and you turn the unit on its side, the toner may not fall out. in this case stick a screwdriver or something in there to loosen the toner.
When done, refit the covers, place the unit back into the machine, restart the machine, and thats it. If the code still appears, you've got toner on the waste toner full sensor, which sits just above where the waste toner part of the process unit is, inside the machine. you can take a cloth and wipe this. although this is highly unlikely, nothing in this industry surprises me anymore.
if this still fails, you could have a faulty sensor or circuit board, but again, highly unlikely
have fun (nothin like gettin your hands dirty) ;)

C-7980 - Means that the waste tonerresevoir in the process unit is full with less than 100,000 copies onthe unit.
Clean/ empty the waster toner and vac.Also clean the sensor.
You may have to change the Process unit if cleaning does not work.

Waste toner reservoir overflow problem (when the total number of copies is 100 thousand sheets or more)
• After E31 is displayed, 1,000 sheets are copied. Or waste toner exceeds 5 g.
Defective waste toner sensor or engine board (KP-5061).
Shake the process unit from side to side and turn the power switch off and then on. If the problem cannot be solved, replace the process unit. After replacing the process unit, turn the power switch off and then on. If the problem
cannot be solved, replace the waste toner sensor or the engine board (KP-5061).
I hope this is helpful,
