    [Error Code] 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.

              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
