    HOW DO i CHANGE THE WASTE CARTRIDGE

  • hobbyist Mar 03, 2009

    Have tried Hakchir's recommendation and want clarification:



    First: Step 3 says "remove feeder". Can you provide more detail as to how? I think this is where I'm getting hung up. I can get the big cover off at step 8, but there's still a bunch of stuff (rollers, the ink cartridges, etc) between me and the waste ink pads. I can see the pads, but have no idea how to get to them. Did I miss something in step 3? All I removed was the feeder tray. Not sure what else to take out at that step and/or how to do it.



    Also, can you give more detailed instructions for how to reset the mother board by "connecting the battery poles for 10 seconds". I am fairly handy and willing to attempt challenging projects, but confess electronics are not my strength... so want to make sure I do this without frying the board.



    Thank you for your help.

    I wouldn't swear to it, but I'm inclined to think that Mr. Hakchir's
    remedy above is bogus, maybe just planted as a joke to mislead
    and frustrate other MP730 owners. I also got the "waste ink nearly full" indicator earlier today and set about to correct the problem per
    Hakchir's instructions above, only I did manage get the paper feeder removed after considerable effort. Without removing the scanner or the motherboard, the waste ink sponges are in view in the bottom of my machine, only they are walled off by the metal mounting bracket and a plastic barrier in the center of the machine. Using an exacto knife, I scored away part of the plastic barrier and prodded at the ink-soaked sponges inside with my screwdriver, and I don't see how these could possibly be washed and used again, they were so fragile. In fact, at one end they crumbled and broke apart like soggy pancakes. Aside from the fact that removing the paper feeder from the back of the machine was extraordinarily difficult and involved removing screws and
    unplugging plastic sockets and sawing away plastic brackets with surgical precision---these machines are clearly NOT designed to
    be serviced in any meaningful way but discarded so that the owner must buy a new one---the fact that Mr. Hakchir didn't describe this process in any detail, but summarized it in one very simple and misleading statement, and the fact that the ink sponges were in such terrible condition, and the fact that removing the scanner and disconnecting the motherboard will apparently do nothing to increase access to the waste ink sponges (it would actually be easier to saw the bottom of the plastic printer case open and take the sponges out from the bottom) coupled with the obvious functional obsolescence deliberately built into these machines to make sure they're disposable leads me to believe that Mr. Hakchir is probably BS-ing us. There is no way in my estimation that it could possibly be worthwhile to go to all of this trouble just to wash out 3-4 cheap sponges and use them again. If this problem has a realistic remedy short of buying a new machine, why doesn't the HP Reference Guide for these machines say a word about this particular message in its menu? My cynical view is that HP doesn't want the public to fix this problem, and would rather sell more printers (of course the real money is in the ink AFTER the machine is sold, but selling new machines is just that much better for the company). In America we used to build the best products possible, ones that were durable and meant to last but now we only build them to throw away so that new ones must be bought.
    My advice after almost three (3) hours of "mucking around" with the MP730 is to just throw it away and buy a printer that is more reliable and serviceable.

I removed the waste ink basket, they are four parts of thick sponges 2 big ones and another two small pieces in the bottom of the printer. you can clean them , dry them and intall them again it will take an hour or more.
1- you have to unscrew the back of the printer, 4 screws
2- after you remove the back on the left hand side there are two sockets installed on for the feeder and ther aother for the scanner, remove the sockets, and unscrew the ground wires
3 remove the feeder
4 to remove the scaner,
press the botton on the right hand side the printer will open, you will see it is attached with a white joint, simply remove the axe, by pushing it with a screw driver, then there are two screws on the right hand remove them, you will find the mother board. remove the wires related to the scanner,after that you can remove it by opening the scaner 180 degrees
free the joint in the right hand first
5-after removing the scanner, you have to unscrew the mother board, 4 or 5 screws, remove all the wire sockets.put it in a safe place, you have to reset it by connecting the battary poles for 10 seconds.
6 remove the metal plate 4 screws
7 remove the sockets connected to the small board .
8 look on the right hand you will see one screw under the small board you can remove it without removing it. you have two in the back and one in the left hand side remove them all
now you can remove the big part of the printer.
when you remove it you will find the waste basket and all the the waste toner. becareful with cleaning remve the sponges, clean them and dry them. clean the bottom of the printer from toner and return them .
dont forget to install all the sockets again.

good luck

WASTE INK ABSORBA FULL


Inkjet printers have a fibrous pad inside them that collects the waste ink from cleaning the print head. Over time, this pad fills up with ink and can no longer hold any more. When this occurs, the printer indicates a "waste ink tank full" error.

Replacing the waste ink absorption pads is something an authorized canon service facility can take care of for you. Once they are replaced, it'll be functional again.

How do you find the waste ink collector on a printer/scanner ?


Inkjet printers have a fibrous pad inside them that collects the waste ink from cleaning the print head. Over time, this pad fills up with ink and can no longer hold any more. When this occurs, the printer indicates a "waste ink tank full" error.

The waste ink absorption pads are inside the printer, in the very bottom. They are usually soaked with ink when full and are very messy.
