Wem, Try soaking the print head in a shallow dish/plate of hot distilled water to remove any dried out ink. You may need to repeat the process a few times to fully unclog the print head.

This methods is for almost all kind Canon printer.
My method is :

1. Unassemble the Printer , Has locking Tabs & 1 Screw.
2. Remove the Mechanism.
3. Remove the Power supply & the connector
4. Place the Base in a sink & remove the Pads
5. Wash the Base in Running Water .then Dry thoroughly.
6. Sqeeze wash the 2 pads in running warm water.until no Ink runs out.
7. Sqeeze dry all the excess water from the Pads & leave to Dry overnite.
8. Reassemble the printer & Run through the Reset as in Wes's Post.

BJC-3000 :
Here is the reset process. You need to carefully follow the steps for it to work. Not to defend Canon but without the waste ink counter you will at some point end up with ink leaking from the printer.
Waste Error Reset :
Step 1:
Start with POWER OFF. Hold down the RESUME button. Press and hold the POWER button. The indicator should light GREEN unblinking.
Step 2: Without releasing the POWER button, release RESUME, then double-click (press and release twice) RESUME. Finally release POWER. Each click of RESUME should cause the indicator to change (first to
ORANGE, then back to GREEN). If the reset is going to work, upon release of the POWER button, the GREEN will blink while the printer goes through its irritating noisy start-up routine of making all the moving parts whirr and grumble (though not, I insist, beep!) and then settle down to unblinking green (I have never achieved this happy status).
Step 3: Press the resume button either three times (according to Wes) or six times (according to Mark's Pidgin it would take 3 double-clicks to get 3 orange lights - hey, I'm just a mathematician trying to make sense of it all!)
Step 4: Press POWER OFF to set data. Apparently this both stores the reset and powers off the printer. When you power on again all should be well!
there were no beeps and 3 resumes worked in step3

THE ERROR CODE INDICATED IS NOT THE WASTE INK TANK!!!!!

The waste ink tank error message is indicated by 6 ALTERNATE flashes of Green/Orange. ie green, orange, green, orange, green, orange, green, orange, green, orange, green, orange.
The error message described in the original post is a printhead problem. It was described as flashing 6 orange and one green. ie green, orange, orange, orange, orange, orange, orange The BC-33e printheads are consumables and need to be replaced after a few years.
The waste ink amount is based on dot counting. It will indicate that it is full after a certain amount of printing has been done. This is generally after 10's of thousands of pages have been through the printer and as such is only rarely triggered by your average user. I would say that most people that supposedly have this "waste ink tank full" error, just need to replace the printhead, and have been resetting the eeprom needlessly. This would explain why a lot of people still have no joy even after reseting the eeprom.
It is shame that one persons inaccurate and inflammatory post has steered so many people in the wrong direction. And you wonder why the engineers don't want that info in the public domain.
