Question about Canon PIXMA MP780 All-In-One InkJet Printer

How do you remove the waste ink absorber pads?

I'm getting the "waste ink near full" message. I know how to reset the counter, but I saw Darklord1's advice to MissBetty re:cleaning the pads, and I'd like to do that first. I downloaded the manual he mentioned, but I didn't find in it instructions for removing the pads. How do you get into the printer to remove them?

Thanks for your help!

    cant find the pads under the cartridge

  • LifeofRiley Jan 08, 2008

    Okay, I figured out how to get to the pads. First, take the sides and the top off the printer. Basically, follow the screws and pray when you snap it off the sides. The top comes off too, though it'll remain attached by wires in the back right corner, so plan ahead for having the top 1/2 of the machine laying upside down by the back right corner. I'd recommend resting it on a piled up blanket/pillow/rags (something you don't mind getting dirty with indelible ink).

    You can remove the spongy pads from their containers with your fingernails. There's a long, thin one dead center (6ish" by 1/4"), one to the left of that (mostly covered by a thin plastic piece which routes the ink downward and which also can come out with your fingernails), and two to the right of the long one.

    Now, how do I get to the waste ink well(s)? They're obviously full--in messing around with the printer, trying to figure out how to get inside, I tipped a bunch of ink on the table. I might have emptied them, but i'd rather make sure.

    The first time I put it back together, the printer didn't work either. For two reasons: The first was because of loose connections. Check the back right-hand corner. There are two short ribbons that unplug easily--if you can reconnect them, you might get power back. The second reason was and remains a mystery. We had everything together, the power was on, but when the ink cartridges tried to move into position, there was a terrible grinding sound. We pulled everything apart again and looked around. Saw nothing. Put it back together. Still grinding. Pulled it apart. Put it back together. Worked fine. A month later, the printer's still going strong.

    Sorry, holborn, but that really only works once or twice before you chance ruining the printer. Reseting the counter allows you to keep printing, but it doesn't get ride of the waste ink, which eventually will overflow.

Ink absorber full

If it is nearly full, you can press cancel / resume to ignore the message. Once the ink absorber is completely full it will prevent you from printing and it will need to be emptied and have the print counter reset.

This is probably something you want them to service.

E8 Waste ink absorber full, or platen waste ink absorber full WHAT MUST DO?

I am told that this will reset your counter and eliminate the full absorber warning that you are getting.

Cleaning the pads is messy, sending the printer to Canon is expensive,

I used a simular reset code for my MP470 and haven't had any problems.

1. To clean physical pads:
Open cover (as if replacing ink cartridge).
Locate waste ink pads, they are far right under cartridge slider.
Pry up waste ink pads (inky, might want to wear gloves).
Rinse pads in sink or with alcohol, dry.
Replace pads. Make sure pads are fully seated.

2. To reset waste ink counter:
Press Menu-Scan-Copy-Scan to enter service menu.
Use arrow keys to scroll to "Service menu counter access".
Press OK.
Use arrow keys to scroll to "ABS-M DOT COUNT"
Press Copy.
Use arrow keys to reset count to zero.
Press OK.
Press Stop/Reset.

Waste ink absorber is full and need to be replace unable to print

The waste ink absorber is a pair of pads at the bottom of the printer paper path (one on each side). You can order replacement pads from a service center. Alternatively, you can resuse them. First, you need to pull the old pads (have plenty of paper towels handy). This can take nearly disassembling the printer. Then rinse the pads with running water until they are clean and then let them dry, if you want to reuse them. Once dry, reinsert them and reassemble the printer.

Next you need to reset the counter for the waste ink absorber. With the printer plugged in but off. Press and hold the Stop/Reset button then press the power button. Once the Power light is lit, press the Stop/Reset button twice while holding the Power button. Release the buttons in any order and the printer is in a service mode. With the lights Green, press and release the Stop/Reset button four times (the light will go orange and green alternately and will be green at this command). Set the counter to zero. Press the Power button to save the setting. Then turn on the printer normally.

Do not reset the counter until the waste ink absorber is cleaned/replaced, you will get ink everywhere.

Please note that the printer was designed to fail about the same time that the waste ink absorber counter hits the point that locks the unit. (ie the waste absorber doesn't get full while the unit is under warranty), the printer may have additional failures soon.

I hope this helps.

Canon PIXMA MP110 waste absorber is nearly full


Thanks for using FixYa. Open the cover, move the cartridges to the centre, and then press the pad of absorbent paper towel onto the waste ink pads. You can locate the waste ink pads to the right of the cartridges. This will absorb a lot of ink in the pads and that will remove the warning after you reset the printer waste ink tank counter. You can reset your Canon Printer by following this procedure—

1) With the printer powered off but connected to a power source, press the Power button while pressing and holding the Stop/ Reset button.
2) When the Power is lit, press the Stop/Reset button two times while pressing and holding the Power button.
3) When releasing the Power button and the Stop / Reset button (regardless of order), the printer will move into a service mode. (Waiting for menu selection)
4) When the on/off lights in green, press the Stop/Reset button 4 times for waste ink counter reset.
5) Turn off the printer.( it must be turn off) then turn it on again.

I get a message saying waste ink near full

It means you need to replace the waste ink absorbers, they are pads under the print engine, around $10.00 but best done in a shop where they have access to the diagnostic mode to reset the waste ink counter.

Waste Ink Absorber is almost full message every time I print

you need to change the inks waste pads, and reset the ink waste counter in service mode.
you can just reset the ink waste counter and still use the machine but it will probably start leaking a bit of ink after a while unless you sit it on something to absorb the excess ink.
to reset the ink waste count just do a search on the web and you will find it pretty easy to do.

Waste ink absorber is full

The printer counts every single droplet ejected by the print head due to waste ink absorber capacity. When the waste ink counter rise to about 90 % the printer shows message 'Waste Ink Absorber Near Full'; in this stage we can still continue printing by pressing Resume button until waste ink absorber capacity reach 100% and 'Waste Ink Absorber is Full' appears.
To fix this problem you have to reset waste ink counter to 0%. Even though we can just reset waste ink counter without resetting waste ink counter, it strongly recommended that you replace waste ink absorber to prevent ink flooding inside the printer.
To reset waste ink counter, perform the following steps:
  • Plug in power cable
  • While pressing Resume button press and hold Power button (do nor release the buttons)
  • Release Resume button (still hold Power button)
  • Press Resume button twice in a row (still hold Power button), after that release both Resume and Power button (then the printer standing bye)
  • Press Resume button 4 times then turn off the printer
In this stage your printer has operated as usual.

Message code on cannon copier

You need to have the waste ink absorbers replaced, the cost of the absorbers should be around $20.00 and service is usually around 50.00. That is a very messy job, you must disassemble printer removed used/ waste ink pads in the bottom of machine reset ink counters and the reassemble printer.
