    [Error Code] Ricoh SP C420DN Error code SC270

    I have a new C420DN that came in DOA with error code SC270. I can't find anything on it here or elsewhere.

    But I got information, but the problem is I don't know to remove the laser where the shutter is attached.
    Is anyone have the diagram of what I need to remove?

    Just removed the electrical board unit and the back cover with 4 screws, but I don't know how to slid out the laser unit.

    thanks


    This is the information I got

    "check the laser shutter the spring may be missing or out of position

    270 LDU shutter error
    270 LDU shutter error
    [D] Sensor output does not
    change even if 1 second
    passes after the LDU
    shutter motor is on.
    Sensor defective or LDU shutter motor defective
    1. Replace the LDU shutter sensor or shutter motor.

    First thing check the shutter, sometimes they just get stuck. Second check the spring attached to the shutter. Thats my two cents good luck

    I don't have access to the part numbers at the moment, but I can almost guarantee the problem is with the shutter stuck/bound up - not the motor/sensor (but there is that small chance). The printer may have taken a jolt during shipping.
    It's very easy to remove the laser, just remove the electrical board unit (basically the back cover with 4 screws, the board is attached to it). The the laser unit can be slid out by pushing the 2 tabs (watch the harnesses, there are 2 attached to the iob on the side you may have to unplug first.). The shutter is attached to the top of the laser.

    Yeh mate, had the laser out last week. Ricoh said to take shutter off and code will never come back. Well, it did come back, everytime. Put shutter back on and all was fine for a few days. Have double checked all slides, guides and spring tension. All seem fine. Really need to find these part numbers. This bloody manual is gunna do my head in.

    P/N for motor is G1022985 and for sensor is GW020020.You can find the parts in the registration section of the manual.
    I have see the same problem twice and the problem was that the motors gear was not engaging good enough with the feelers gear(bended bracket maybe).The assembly is the same as in spc 410."

      There's a fair list for this one.

      1. LDU Shutter Error - adjust SP 9001-1 and -2
      2. LDU shutter spring fallen off
      3. Update engine firmware above 1.05:2
      4. Fuse 5 on PSU blown
      5. Refer to TSB 8 on Tessa.

      Hit it.
