Canon Pixma MG3550 Disassembly

필요한 것

  1. Canon Pixma MG3550 Disassembly, Preliminaries: 1 단계, 이미지 1/1
    • You may wish to remove the ink cartridges if you are planning a radical disassembly, though this is not necessary for the purposes of this guide. Follow the instructions in the User Manual, and place them in a polythene bag, both to prevent them drying out and to avoid ink stains on your work surface or clothes.

    • Switch off the printer if it's on, by pressing the power button and waiting for the power light to stop flashing. Now unplug the power cable and USB lead (if connected).

    • Lift the scanner lid as far as it will go. Squeeze the finger in the centre of each hinge in order to detach it.

  2. Canon Pixma MG3550 Disassembly, Control panel cover removal: 2 단계, 이미지 1/1
    • Using a jimmy (or similar tool), release the clips around the edge of the control panel cover, then lift off the cover.

  3. Canon Pixma MG3550 Disassembly, Rear screws: 3 단계, 이미지 1/1
    • Remove 2 cross head screws from each side of the back of the printer.

  4. Canon Pixma MG3550 Disassembly, Right panel removal: 4 단계, 이미지 1/3 Canon Pixma MG3550 Disassembly, Right panel removal: 4 단계, 이미지 2/3 Canon Pixma MG3550 Disassembly, Right panel removal: 4 단계, 이미지 3/3
    • Remove 2 cross head screws from the front of the printer on the right hand side.

    • Standing the printer on its left hand side, unclip the right side panel, first along the top edge and then at the back. It should now come away completely.

  5. Canon Pixma MG3550 Disassembly, Left panel removal: 5 단계, 이미지 1/3 Canon Pixma MG3550 Disassembly, Left panel removal: 5 단계, 이미지 2/3 Canon Pixma MG3550 Disassembly, Left panel removal: 5 단계, 이미지 3/3
    • Unclip the rear of the left side panel.

    • Unclip the front of the left side panel.

    • The side panel is still retained by a hidden clip beneath a rectangular hole near the edge of the control panel. Release it by pressing down on it with a flat screwdriver blade. The left panel should now come away.

    Worth noting that the left panel appears to be secured by 3 clips at the bottom edge on the 3650 model, is it the same on this one? Slide a lifter in between the bottom panel and the lower edge of the left side panel to free and it should just lift off.

    • Remove a screw from the front left hand corner of the control panel.

    • Remove a screw from the middle of the left hand side of the control panel.

    • Remove a screw from the rear of the control panel.

    • Lift off the control panel, taking care not to strain the ribbon cable, still attached.

    • Disconnect the ribbon cable.

    How do you disconnect the ribbon cable? Just pull it?

    Hallo, Wirklich den Stecker abziehen ? Ich bekomme das nicht ab ... Hab Angst es zu zerstören

    Heiko Klittich - 답글

    Hello, Are you sure you want to unplug it? I can't get this off... Afraid of destroying it

    The ribbon is reinforced where it enters the connector so no danger of tearing it. Grip it close to the connector and pull quite hard.

    Das Band ist dort verstärkt, wo es in den Stecker eintritt, sodass keine Gefahr besteht, dass es reißt. Fassen Sie es nahe am Stecker und ziehen Sie ziemlich fest.

    You should add a photo of the disconnected cable. I have tried to pull the black connector. But it is the part attached to the motherboard

    Mathieu - 답글

    Pull the ribbon not the black connector. See also 케이블 커넥터 인식 및 분리 (I no longer have this printer so can't get extra photos. Perhaps you'd like to add one?)

  8. Canon Pixma MG3550 Disassembly, WiFi module removal: 8 단계, 이미지 1/2 Canon Pixma MG3550 Disassembly, WiFi module removal: 8 단계, 이미지 2/2
    • Disconnect the WiFi module ribbon from the main logic board,

    • Remove the screw holding the WiFi module bracket in place and remove the bracket and module together.

    • Note that this screw is different from all the others.

    I seem to have a later version (board is D67 not D38) and the wifi module is to the right of the logic board, not on top, so doesn't need disconnecting to get the scanner off.

  9. Canon Pixma MG3550 Disassembly, Scanner unit disconnection: 9 단계, 이미지 1/1
    • Disconnect a wide ribbon cable from the top of the logic board.

    • Disconnect a narrow folded ribbon from the bottom left hand corner.

    • (The connector with 2 red wires on the left hand side of the logic board does not need to be disconnected.)

    Unroll the two red wires from the hook.

    • Remove the screw at the top left of the glass pane

    • Remove the screw at the bottom left of the glass pane

    • Then gently lift the 2 tabs of the screws you just removed, and slide the whole glass pane by about 1/4inch (5 mm) to the left

    • (Note: Avoid any dust inside the scanner unit.)

    • You can stop here if you're not interested in the printer part, or put back the glass pane and go on.

    • Remove a screw from the well that housed the WiFi module.

    • Remove the screw from the front left of the device.

    • Remove a screw from the front right hand side.

    • Release a catch on the rear left hand side of the device (as seen from the rear) and lift the scanner unit off.

    • You will now be able to see the print mechanism much more easily and proceed with any further disassembly that might be needed.

    Note: if you want to further disasemble the scanner unit, don’t try to pry it open by force like I just did :-/.

    Instead, gently slide the upper glass pane from right to about 5 mm and it should come loose.

    Please then make sure not to let any dust in of course.

Very good description. I need to empty my ink collection tank/tray. Once I have removed the scanner assembly as you describe, will I then gain access to theis container? Thanks.

John Stuart - 답글

See link to YouTube video below. You need long tweezers and be careful when replacing the pads as they can drop into the mechanism easily .. which is why I found this tutorial on how to dismantle the printer!

Habe schön zerlegt, werde sicher zusammenbauen, wollte aber noch wissen warum das Papier im rechten Drittelbereich zerrissen wird.

Muß noch versuchen den Papiereinzug zu putzen bzw. den Fehler zu beheben.

thank you very much! you saved my workday! i am a girl and i really appreciate so simple manual. i wish every manual was so simple! :)))

PATRICIA - 답글

Well done Patricia! You never need to apologise or anything of the sort for being a girl - girls are often better at this sort of thing as they tend to be more careful whereas boys sometimes rush on in a slapdash manner as if it were a race! Just believe in yourself and don’t be afraid to make mistakes - that’s how you learn - and you’ll soon be an ace fixer!

Philip Le Riche -

Well done explanation. You saved my printer from trash. Unresolved head alignment (tried everything) by opening the printer and perfectly clean the plastic band behind heads (it’s a pace counter in reality), as well as the plastic circle on the side opposite to head rest . were really dirty and giving false positioning to the head. Now works smoothly and precisely as new. Many thanks !

Alberto Lampis - 답글

Thank you! Worked well also with the MG3650S, where you don’t need to do step 8, as the WiFi controller is in the middle-right of the main board.

Hi, my paper feeder lost all their plastic bands.

But the lower space is too hollow to let me fix it. Is it possible to further disassembly to reach that part?

Or can you think of any workaround to fix that?

Thanks

My MG2260 is unable to find paper in the tray, is there a simple fix

mjpenhey - 답글

Hello everyone and thanks for the very useful guide. My Mg3650 has a paper loading problem, that is, sometimes it is unable to take it, other times it takes it a little crookedly and the paper gets stuck inside the printer... I noticed that the trolley with the two rubberized wheels which is used for pulling the paper in, it doesn't put enough pressure on the paper because I think it has a broken spring... before opening the printer following the guide, can anyone tell me if it is possible to replace or repair the spring? Maybe it's just unhooked but I'll only know when I open it. I'm wondering if any of you have had the same experience. Thank you!
