They are attached to a white plastic carriage/platform to hold them and they also have a small raised nipple in the center of each, but NO Foam OR any other type of absorbent material.anywhere to wash clean.

The black ‘bases’ came off easily and I cleaned them up, but the white sub bases are a part of this white carriage and they don’t come off, unless you do some major dismantling.

So far, I have just unscrews the right end off my MP150 to get access to this white Carraige..

The White carriage moves only a short distance and back again; of 20mm ( like a Typewriter ) from the print area..

But underneath the White Carriage, I found two plastic ‘tubes’ attached to the underside each of the white nipples and through to deep in the back to another compartment, to a cylindrical plastic object.firmly attached / screwed to the rest of the mechanical parts.

Is this the Ink waste ‘tank’??

IF this is a waste tank, HOW dose this ‘tank’ get emptied?? I have tried to see if these tubes would come off and to see IF any ink dribbled out, but, they wouldn’t move.

OR are they electrical , for the sensors? AND leave them alone??

I did find ink everywhere, pooling in the plastic cavities of the Frame under the Cartridges and cleaned it up..

SO, I didn’t find exactly what was mentioned in the Instructions, but something completely, different.

I did try all last nite to get a copy of the Service Manual for a CANON MP 150, but NO luck.

Do I JUSTt put it back together and reprogram the Programing?

ANSWERS????? PLEASE.
