Re: C-3300 Error in KM-3050 Printer
Start with the inexpensive items on the list, like the lamp and inverter. But in the end, you’ll probably end up replacing the CCD or SHD PWB. =^..^=
If you’d like a serious answer to your request:
1) demonstrate that you’ve read the manual
2) demonstrate that you made some attempt to fix it.
3) if you’re going to ask about jams include the jam code.
4) if you’re going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: C-3300 Error in KM-3050 Printer
You need to reread what Blackcat posted. If you’re lifting the ADF and scanning from the glass the ADF isn’t involved.

Remarks
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.
Display:
CCD: Main Exposure Lamp
CID: Document Processor Exposure Lamp (inside the feeder)
Method
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.
Completion
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.

The service login works great!
Code to test the lamp is not 601 but 061.
