    Kyocera KM 4050i Error Code c3300 — No Scan Lamp

    >On intialization the scanner moves freely back and forth-OK.
    >On initialization the Scanner LAMP does NOT turn on.
    >I also checked scanner motor ops in service mode-OK.
    >Checked scanner lamp ops U061-Dead.
    >Chacked DP Read U073-Dead.
    >Cleaned and reseated all connectors-Still Dead.

    I am wondering if the SCANNER INVERTER or SCAN LAMP are a common problem with these.
    only 189,000 clicks

    I was thinking scanner lamp assy or inverter PCB, am wondering what others have run into

    Thanks,
    Mike

    It’s not impossible, but I’ve never seen a bad exposure lamp or inverter on the Falcon III series machine. I’ve got machines over 1.5M prints.

    The things you can do for free include pinning out the ribbon cable, and re-loading the firmware. Cost-wise, I would start with the lamp & inverter. It could also be the ribbon cable to light source 1 or the engine PWB, but I’d save those for the next round of parts replacement.

    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.

    Thank you Blackcat… I am about to go over there and do just that. My lamp and inverter PCB have arrived. I will post results.

    RESOLVED

    It was the lamp inverter PCB. What a PITA to get to.

    i have one time seen it be the lamp itself. sounds like a very uncommon problem though. luckily i had a parts machine to get it up and running the same day. customer called in with the code, sorry i dont remember what the code is now

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.
