    Thanks for that, I did in fact find the sponge you were refering two. Afraid it did not solve problem, as the orange light then started to flash 5 time, which indicated that the print head was either not aligned or there was dirt on it. I took print head off, found nothing obviously wrong with the head, re-installed it and still had the same amber lights flashing. Had problems before with guosting on printing jpg's and was unable to solve problems, which again I believe is print head orientated. Had heard of guys removing print head and boiling it for 30 minutes in water to overcome problem. Have changed printer now for the IP4500. Hopefully this one will last longer than previous. Thanks for your imput and will continue to monitor your site for other useful tips.

Try following reset procedure:

1. Turn off printer.
2. retaining button Resume/Cancel press button POWER - indicator it will catch fire by green color.
3. let go button Resume/Cancel, continuing to retain POWER.
4. press button Resume/Cancel of 2 times, retaining POWER, after which let go all buttons.
5. when indicator will be lit BY GREEN - press button Resume/Cancel of 4 times!!!
6. turn off printer by button POWER.

If reset does not work, you have to take apart the printer and empty the ink tank located at the back bottom right corner of your printer, replacing the sponge inside.

Here is an alternative procedure

1) With the printer power turned off, while pressing the Resume/Cancelbutton, press and hold the Power button. (DO NOT release the buttons.The LED lights in
green to indicate that a function is selectable.)
2) While holding the Power button, release the Resume/Cancel button. (DO NOT release the Power button.)
3)While holding the Power button, press the Resume/Cancel button 2 times,and then release both the Power and Resume/Cancel buttons. (Each timethe
Resume/Cancel button is pressed, the LED lights alternately in orange and green, starting with orange.)
4) When the LED lights in green, press the Resume/Cancel button 4 times (Each time
the Resume/Cancel button is pressed, the LED lights alternately in orange and green, starting with orange.)
5)After the function (menu) is selected, press the Power button. The LEDlights in green, and the selected function is performed. (When theoperation completes,
the printer returns to the menu selection mode automatically.)

My Canon BJC 6000 Printer is beeping 10 times and cartridges will not move from left to right?

Probably not worth messing with this, since I saw a canon MP250 in Wal-mart for $32., yesterday.

The actual "waste tank full" error is 10 beeps + 6 flashes of the power light.

Waste tank is full:

"waste ink tank" is actually a "felt" like material under a white polystrene foam like material. To get to it, you have to remove the case of the printer and it is at the very bottom beneath the printer paper rollers and electronics.


If your waste tank is full, it wont be white but will be black+other colours and will have the appearance of being soaked with waste ink.


Washed the felt pad by soaking and rinsing in lots of cold water and dried it with a hot air drier and reused it. But it is a very messy process.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

Waste tank near full

The waste ink take is actually just a felt pad that sits under the printer mechanism inside the case and absorbs the ink from your cleanings

Try this:
1 Power off printer
2 Hold RESUME button then press and hold POWER. (The beeper MAY sound once, or may not depending on your model.)
3 Hold POWER and Release RESUME.
4 Press RESUME twice then release both POWER and RESUME buttons.
5 When the indicator lights steady, press RESUME 4 times (for the S900, 3 times for the 8200 apparently).
6 Press power to set data.
7 Print away!

Let me know if that didnt solve your problem

Waste ink tank near full

Go about half way down this page and it shows you how to fix this problem.

It will require you to open up the printer to access the "waste tank" which is actually a thick felt pad.

Reset the ink waste tank code, and now pixma ip4000 won't turn on

Try removing the printhead and power up, if it works you need a new printhead. Many times when the printhead goes bad the machine won't power up.

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.

Waste Ink Absorber full - Canon Pixma

Reporting solution by daweed:
This is true with many Canon Ink Jet Printers: Eventually, you'll get an error message "Waste Ink Tank Almost Full, Contact Your Canon Repair Center". Canon is totally sly about this, and is actually a pretty ridiculous design flaw that they should be ashamed of- planned obsolescence. Anyway, don't let this problem discourage buying an otherwise fantastic Canon printer.
This problem will also be indicated by flashing orange lights on your printer. Different flashes for different models.
LOOK IN YOUR PRINTER MANUAL TO KNOW WHAT NUMBER OF FLASHES INDICATE. In any case, your computer printer software will also tell you exactly what is going on.
You need to do this after you get the WASTE TANK ALMOST FULL message and the printer continues to work, but BEFORE the WASTE TANK FULL message and the printer completely stops. I think. ;-)
Here's the fix:
The waste ink take is actually just a felt pad that sits under the printer mechanism inside the case and absorbs the ink from your cleanings. From what I gather, its both a time consuming and expensive proposition to take to Canon to fix. And they won't tell people how to do it themselves. Well, I WILL. And this works.
Remember of course, you've got to cycle the cleaning process a huge amount of times to get this to occur.
But when it does, there is a fix-it-yourself solution that is both safe and effective for the printer, and free. You have to be slightly mechanical to do this. If you get this message and you've never used a screwdriver and are all thumbs, well, Canon gotcha. But give it a shot even then, or give it to someone halfway coordinated to do this for you.
You may RESET the printer code first if you like or do it after you clean the pad
In some cases you may need to REMOVE THE PRINT HEAD FIRST or the reset code will not work. This was true of the S900 and i960 so, remove the print head first before doing this reset.
This is the correct code for the S and I (like i960) series of printers. (M series below this)
1) Power off printer
2) Hold RESUME button then press and hold POWER. (The beeper MAY sound once, or may not depending on your model.)
3) Hold POWER and Release RESUME.
4) Press RESUME twice then release both POWER and RESUME buttons.
5) When the indicator lights steady, press RESUME 4 times (for the S900, 3 times for the 8200 apparently).
6) Press power to set data.
7) Print away!
For other codes for other printers and more info go here to this big forum (but try the above first) Fix Your Own Printer Generally many of Canon's models use exactly this same code, the i models use the same code, all the s models use the same code.
I did this and it works fine! No more error messages and so..."

Sounds like every other inkjet, they store the waste ink from cleaning cycles into a ink asorba box (felt pads). The machine estimates when these pads will be potentionally full and shuts down so no one ends up with ink pouring out of their printer on to their desks.

SO TAKE IT TO HAVE THE WASTE INK BOX REPLACED AND THE COUNTER RESET, or replace with new cause a brand new mechanism with gen ink, fresh pads, year warranty, is a most times a more economical option.
