  5. Dell c1760nw Clean main mechanics cleaning and making it work, Continued: Remove TopCase: 5 단계, 이미지 1/1
    • Carefully lift the cover (Attention: cable connection to the display is hanging there) and rack it to the back of the printer (move it back and forth to unhook the locking nipple): unplug the display connector (yellow lines) from the I/O board, unroute the cable and remove the cover.

  6. Dell c1760nw Clean main mechanics cleaning and making it work, Remove left housing part: 6 단계, 이미지 1/1
    • Place the printer on the right side and remove the left side panel (there are 2 lugs under the printer)

  7. Dell c1760nw Clean main mechanics cleaning and making it work, Next: Remove the left housing part: 7 단계, 이미지 1/1

    • I/O card is secured with 4 screws, loosen all 4.

    • There is another screw on the USB port: Loosen it

  11. Dell c1760nw Clean main mechanics cleaning and making it work, Remove the fan: 11 단계, 이미지 1/1
    • The fan is secured to this plate with a screw (red arrow): Loosen the screw and unlock the locking device on the other side of the fan.

    • Remove the fan, disconnect the cables and plugs on the upper control board (no photo).

  12. Dell c1760nw Clean main mechanics cleaning and making it work, Unroute wiring harnesses: 12 단계, 이미지 1/1

    • Loosen 4 screws

    • Pull the main gearbox carefully and straight off the printer. (Caution: loose gears!)

    • Last photo: This is what the dismantled main gearbox looks like: The completely muddy (color & grease) drive gear is the black (below)

  15. Dell c1760nw Clean main mechanics cleaning and making it work, C) Remove board with color control: 15 단계, 이미지 1/1
    • Carefully pull the upper flexible cable out of the base

    • 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.

  17. Dell c1760nw Clean main mechanics cleaning and making it work, Washing the gearwheels ...: 17 단계, 이미지 1/3 Dell c1760nw Clean main mechanics cleaning and making it work, Washing the gearwheels ...: 17 단계, 이미지 2/3 Dell c1760nw Clean main mechanics cleaning and making it work, Washing the gearwheels ...: 17 단계, 이미지 3/3
    • 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!

  18. Dell c1760nw Clean main mechanics cleaning and making it work, First success: 18 단계, 이미지 1/2 Dell c1760nw Clean main mechanics cleaning and making it work, First success: 18 단계, 이미지 2/2
    • 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.

  19. Dell c1760nw Clean main mechanics cleaning and making it work, Second success: 19 단계, 이미지 1/2 Dell c1760nw Clean main mechanics cleaning and making it work, Second success: 19 단계, 이미지 2/2
    • And once again: before and after

  20. Dell c1760nw Clean main mechanics cleaning and making it work, Clean the chassis: 20 단계, 이미지 1/2 Dell c1760nw Clean main mechanics cleaning and making it work, Clean the chassis: 20 단계, 이미지 2/2
    • 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.

  21. Dell c1760nw Clean main mechanics cleaning and making it work, After assembly: 21 단계, 이미지 1/2 Dell c1760nw Clean main mechanics cleaning and making it work, After assembly: 21 단계, 이미지 2/2
    • 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!

결론

Congratulations, you did it!
