Step 9

              Remove I / O card

Loosen all connectors (pull plugs carefully out of sockets)
Pull both flexible cables out of sockets. Caution: the wider flexible cable has a base with lock. Lift it carefully with a fingernail, this releases the flexible cable and allows it to be easily pulled out of the socket.
I/O card is secured with 4 screws, loosen all 4.
There is another screw on the USB port: Loosen it

Step 16

              Remove the color control gear

Next, we remove the color control gear (black, large plastic bracket with 15 meshing gears (5 screws have to be loosened).
CAUTION when removing the bracket so that the gears do not fall out!
2nd photo: removed condition and THE central problem: The paint particles have combined to form a sticky mass with the gear grease.

Step 17

              Washing the gearwheels ...

Washing the gearwheels.
A toothbrush with plenty of hand soap brings good success here!
Attention: Every gear wheel has its position! Do not mix them up!
Attention: Dry all parts (brackets, gears) very well! “Knocking” the ingredients on paper towels helps!

Step 18

              First success

The “before / after” evidence ;-)
I used low-viscosity grease to grease the axles and the teeth. Finally, add a splash of Balistol to the grease on the axles.

              Second success

And once again: before and after

Step 20

              Clean the chassis

Now the chassis should be cleaned (only for the good feeling! and because of the care…)
Moist all-purpose wipes" in a resealable plastic cover are ideal for cleaning.

Step 21

              After assembly

The assembly is done in reverse order… Until the printer only needs the right and front housing part plus the paper flap.
If the error message 007-371 appears again at the first attempt of the printout, this is nothing unusual. The paint mixing drive usually still needs a “boost”.
Turn the printer off and on again a short time later. Now you help the gear a little bit on the jumps: for this you put on a screwdriver as shown in picture 1, hold it with a little pressure so that you can get the gear wheel touched with it a little in motion when it is released by the small relay.
This usually does not happen by itself during the first printing process (although the spring in the gearbox, which you probably noticed earlier, should actually trigger this momentum). So, put on the screwdriver like this and send a print job.
In picture 2 you can see a better close-up to attach the screwdriver exactly.
If everything works, then reassemble everything else and: DONE!
