   Dear All Friends

   i have a problem with 250ci (cdc 1725), gaves 7102 — 7103 — 7104
   total counter :90000
   main fw :2H7_2F00_010.007

   How are the values in U155?

   If they are nearby 20, you lost the 24V for the tonersensors.
   Did someone exchanged the toner container motor in past?
   If yet, please check the wiring above the main front pwb, at a few cases in europe, the wiring would damaged by mounting the plastic cover above the main- and sub front pwb….
   In worst case, the engine pwb is damaged totally, this happened in france.

   Mike L,

   if you are using the old FW you�ll get C7401 !!!
   It�s totally different Errorcode. Unknown Dev-Unit
   But he get Tonersensor Errors.

   Re: TaskAlfa 250Ci C7102 — C7103 — C7104 Error Codes
   

   I had a Saturn recently with a dead color developing motor. At first it was giving magenta «Add Toner» indications. With the new motor it changed to C7103, it think.

   The secondary problem was that while the color developing units were not agitating, the toner add system had been packing toner into the magenta developing unit. When it couldn’t take any more it compacted the magenta toner in the spout of the toner cartridge. Once the developing motor was turning again, it took about three days to detone the magenta developer to the point where it tried to add magenta toner, unsuccessfully.

   My solution to the secondary problem was to beat on the toner cartridge until the agitation mechanism would turn again. =^..^=

   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: TaskAlfa 250Ci C7102 — C7103 — C7104 Error Codes
   

   Hello,

   I have a problem with a C7103 on a TA 250ci.
   I got in U155 (Toner senor output) «26» instead of «+300».
   I tried the DV M in another TA300ci and there is de DV M working perfect!
   I changed also the engine pwb without result, changed the DV CMY color motor, front main/sub pcb, motor control pwb without result.
   Could it be a broken gear in the main imaging drive unit?
   This is my last option because it’s a lot of work to disamble this unit!

   Before i had also C2810. I cleaned the waste toner pipe of the ICL motor. It was stuck with toner. (I did the spring back inside)

   thx.

   The Voyager and VoyagerE series both used to shatter the color developer drive gear, but the Saturn series doesn’t seem to do that in my experience. More common is motor failures. Since there are several motors of the same type, I would remove the back to see if the color developer motor is turning. If no, I would swap around the color developing motor to see if a different motor will turn. =^..^=

   Hello blackcat,

   I’ve changed already the CMY DV motor without result…
   Monday i go back and change the DV M unit with a new one (not a used one).
   I can still print in B&W.

    Hello,

    Problem solved by swapping the green relay pwb (next to the orange relay pwb) who’s connecting the drums and dv’s.
    DV Magenta toner values again +400.
    Anyway thx to all!
