Pro-100. - Still Having Problems With Displayed Ink Levels

[turbguy]

Doing some eBay searches, it's interesting to see some are selling parted-out pro-100 printers:

Full sets of carts, factory marked "setup"

Unopened print heads in foil bags but no box

PRO-100 printers without print heads or inks..

Hmmmm...

Sadly, that's established procedure for some folks. The Setup carts are actually full cartridges but marked to differentiate if someone tries passing them off as full retail... but overall the parts are worth more than the whole printer so, once again there will be perfectly good carcasses being tossed in the tip or missold to the unwary who don't know to check for the printhead, etc...

Frustrates me no end that such practice goes on but it's economics 101...

This is to confirm that thus far, when the chips have been disabled, the following behavior will occur when reset.
The chips will report FULL when reset.
As the ink is consumed, the FULL level will be sticky and remain there for a long time and the ink level monitor will be inaccurate as far as the intermediate levels are concerned.
When the ink levels get CLOSE to being low, the ink level display will show about 80% full.
Further use will use the ink AND the printer will report a LOW condition when the optical sensor kicks in and detects that the reservoir side has no more ink.
There is broad consensus that at this point, we should reset the cartridge chip and refill it and we should perform this on ALL the others at the same time to extend waste ink pad absorber life. Doing so, will pretty much make the ink absorber pad life a non issue for the life of the printer during normal use.

So the critical optical sensor, still works and will report when the tank side is empty even after the chip has been DIMed and RESET. This fulfills the KEY role of a working chip on the printer to allow the critical optical sensor function and its warning.

In the new year, we will see whether Redsetter will be able to determine what "routine" Canon has thrown into the works to cause the non display of intermediate levels and whether this can be fixed by a resetter or whether the chip has been permanently modded by Canon.

In the meantime, we can rest easy that with Roy's insightful observation and concern, further tests show that the optical sensor will warn of a low condition and we should refill at that point.

With each new generation of printers we discover something new and hopefully we find ways around it or understand what the issue is what it means.

I didn't know the CLI-42 cartridges also came in a setup version? Maybe these cartridges with possibly different chips are needed for the setup, like other new Canon printers also need a special set of setup cartridges. Even if the capacity is the same as for the regular CLI-42 cartridges, the "setup" chips may behave differently when resat?

Setup? Where did it say "Setup" on the carts that come with the PRO-100?
I did not see anything describing them as Setup.
In fact they come filled more that we would ever be able to do so by manually refilling.

It says so on Canon USA site: http://www.usa.canon.com/cusa/consu...hoto_inkjet_printers/pixma_pro_100#BoxContent

Under the headline "What's in the box?" it says setup ink tanks. But maybe the included cartridges are regular CLI-42 cartridges?

Yes, we were initially scared by the description until we began receiving the inks on the printers and discovered otherwise. This is an EXCEPTION to the current general practice. For other printers models, setup generally means what it says today.....setup and then proceed to purchase real.

Which firmware does this occur with?

Who is the confirmation from?

Has someone DIM'ed a retail cartridge and had the ink level monitoring issue, or, has this issue only been reported with the "setup" ink cartridges? And, again, what firmware was in use?

1.02 , DIM'ed on setup.
