[Error Code] MP C4504 SC220-04 After "all clear" performed

[copier tech]

Hi all,

One of my junior techs ran an all clear on a working MPC4504 (no idea why) however now we are stuck with this error.

The Birth certificate has been "lost" so cant re-enter the cleared settings.

Not sure where to go next, new NV-Ram!?

3. Download the data of the new laser unit to the main body with SP2-110-005.

Thanks, he followed the manual as if a new laser was replaced I suggested trying forced line position no luck.

I will have a look myself.

After you finish beating the tech go and run SP2118 to zero the skew mirrors. Once thats done the copier allows you to run SP2110-5 to reload all the laser unit settings that are stored in the laser up to the copier. This step is missing from the manual as it assumes that you are fitting a new laser unit with every thing zero'd from the factory.

What did you finally end up finding to be the problem?
I am dealing with almost the exact same problem. A junior technician causing me heartaches almost everywhere he goes.
Any guidance on what you did to resolve the 220-04 code on your c4503 would be greatly appreciated.

I wish that the "All Clear" wasn't available in the normal service mode, maybe not even the special service mode. Have only had to use it once as a last-ditch effort recommended by Ricoh, but I had the birth cert. and was able to re-enter the non-defaults and all that jazz.

Without the Birth certificate, you can spend HOURS trying to get a machine back to "normal" (as a fellow tech told me, but I think they ended up swapping the machine out in the end).
Might be a really dumb question, but Did you or your tech look on the front door under the scanner support (that is stored there during setup) for the Birth Sheet? Don't know why anyone would take it out other than for the event of an all clear.

I'd try to put another machine's data even if each Ricoh has its own birth certificate

Good idea. This may get you in the ballpark and keep it from coding so fine adjustments can be made.

couldn t you just copy a working machine unto to a sd card and upload it to the
down machine and then deal with the sn mismatch via super service mode...

Re: MP C4504 SC220-04 After "all clear" performed

Did you even look at the Service Call Conditions in the service manual? SC220-04 is a yellow LD1 synchronization detection error.

The interface harness to the synchronization detection unit damaged or not connected correctly.
Synchronization detection board defective
Beam does not enter photo detector.
Abnormality around GAVD
LDB defective

1. Turn the main power OFF/ON.
2. Check for condensation on the LDB.
3. Reconnect the connectors between LDB (Synchronizing detector board) and IPU.
4. Replace the LD unit.
5. Replace the IPU
6. Replace the harness between LDB (Synchronizing detector board) and IPU.

Whiskey Tango Foxtrot are you suggesting Slim? A tech READ the friggin' manual? How CRUEL CAN YOU be?

you're a heartless MoFo! I guess that's why we agree on a lot of things! Keep up the great work!

try using a birth record form another same model it will at least get you in the ball park

If it is a hard failure of the LDB or a laser synchronization detector no amount of loading data from a birth certificate is going to correct it.
