I may have come to the end of my refilling with my printer from today onwards. However I am not too sure if this is true. My printer (my one and only printer) was sent for repaired recently and the circuit board was completely replaced. The replaced board has different ROM version.
A bit of history:
I had 2 completed sets of OEM canon cartridges (CLI8 CMYK & PGI5BK) with all the chips having reset via resume/stop button or through the accept warranty void option. Except one problem CLI8BK chip from the later batch (purchased in early 2007) that perpetually couldn't be reset via resume/stop button or accept warranty void and a yellow chip cartridge which has yet trigger the low ink/empty. For who would like to know more history of this problematic CLI8BK chips, you may read my post #23 at this thread http://www.nifty-stuff.com/forum/viewtopic.php?id=2445&p=3
Situation Now:
Before the replacement of the circuit board, I was able to reuse the 1st set of chips & the 2nd set chips except the problem CLI8BK chip after all these cartridges had undergone low ink/empty. My printer used to be capable of detecting the 1st set of chips cartridges fine (just merely losing the ink level monitor). Now with the replacement circuit board of later ROM version, my printer is no longer recognizing these chips (not even the first sets of chips) that used to work perfectly without ink level monitor. See below picture A. This will mean I can no longer use refill anymore.

However I needed further test before drawing such conclusion. Such as getting these chips reset by someone who own a chip resetter and then experiment to use these chips after they have reach low ink/empty again. Unfortunately I can't be sure whether if this chip after having been reset by a chip resetter, will they be able to use on my machine with later circuit board ROM version after they have used and reach low ink/empty. Losing ink level monitor is okay for me but completely not recognizing this chips will not allow me to reuse them.
The only person I know of here that own the resetter is pharmacist and had already contact him for assistance. I had told him one/two weeks ago, that I wll not send the all the chips for him to reset with chip resetter after realizing that I will lost ink monitor again and will need constant reset with chip resetter. Though I was planning to send him the problematic CLI8BK chip for him to attempt to reset. Now the above problem had strucked. At this moment, I won't be able to be 100% certain whether if I am completely removed from refill with my machine unless I am able to reuse these chips that had been reset via resume/stop button or accept warranty void previously. The Euro rate which pharmacist asked for is reasonable for helping to reset. Unfortunately I am from oversea (not US or EU counterparts). So after converting Euros to my own currencies, it will mean $40++ to reset all the 10 chips and $20++ to reset 5 chips (in my own currencies). This is steep for me. And here where I am, I don't have access to compatible cartridges that comes with reset chips.
So I am battling what to do with this situation now. In the meanwhile, I guess I will lay low from this forum and all other form of experiment and testing.

Tin Ho, I don't have a defective board now. Because my first paragraphy in my first post already pointed out that I had sent my printer for repaired. They had replaced a new circuit/logic board with a later ROM version. This is as good as meaning the printer logic board has upgraded firmware.
