PRO-10 waste ink counter reset

[palombian]

As already reported on this forum by @Manu for the PRO10-S, I was able to reset the counter of a PRO-10.

1. Connect the printer via USB (it must be the only printer on the PC).

2. Start the printer in the service mode.
i. With the printer power turned off, while pressing the Resume/Cancel button, press and hold the Power
button. (DO NOT release the buttons.)
ii. When the Power LED lights, while holding the Power button, release the
Resume/Cancel button. (DO NOT release the Power button.)
iii. While holding the Power button, press the Resume/Cancel button 5 times, and then release
both the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed,
the LEDs light alternately).

3. Start service tool 5204. You will see the printer serial number on top.

4. Place 2 pieces of A4 paper and press button EEPROM to print the actual status. On line 2 you will see D=999.9 indicating the percentage of waste ink accumulated.

5. Press button Ink Absorber Counter/Main/Set. You will receive a message a service has been executed.

6. Press button EEPROM again to print the new status. You should see D=000.0 now.

7. Close the service tool and power the printer off and on again.

Nice!

Note the DF. Before reset the DF = 00004, which means ~4 months till waste counter full at the current usage pattern. The new DF = 1000, or over 8 years. The DF should change with usage patterns, otherwise, what good it.

Why Canon includes the DF in the EEPROM report is up for conjecture. It doesn't matter to the user. It doesn't matter to the service tech who resets your counter for $$$ because they can see the waste ink counter value.

So why is it there? Maybe because they can or maybe it provides evidence of tampering.

No idea of DF, but other information seems plausible.
60 cartridges were used x 14=840ml ink for 2500 pages=0.33ml/A4 page.
Seems reasonable for graphics as been told.

Although the printhead has been changed 2 times (CH=002). Not impossible since the seller got the printer from the factory where he works and nobody had to pay this out of his pocket.

My thought - not known fact - is that once Canon could calculate waste ink volumes (D) then it was a relatively simple calculation applying "D" with respect to time to get DF (months until waste ink pads full and reset required). Canon knows the volume of ink directed to the waste ink pads for any and all function performed, whether initiated by the user or by the firmware/software. The only variable is the user. The frequency of printing and the volume of ink used per print job can be factored over a unit of time. From this Canon may calculate how many months remain till ink pads are full. If the variable of the user's printing habits change, so too can the calculation of DF. Unless Canon knows the future - either from supernatural powers or Area 51 alien technology - then it is all old school mathematical calculations.

The number of cartridges gives you an idea on how long the printer may last before needing another waste ink counter reset. Maybe you can make it to 70 cartridges before the printer halts printing and require a reset. Let us know. @The Hat will still be around. Maybe by then he'll get a raise and an office with a window.

Maybe the seller knew about the 4 months...
No kidding, he got the printer for free - with the remaining carts - since it was written off.
When he had to buy ink himself he (or his wife) realised it was too big for a home printer anyway.
He did not seem in need of money, that's the kind of people you have to buy from.

I like stories with happy endings. Great find, Palombian.

You planning to fit an external waste ink tank to it then?

This one was for spare.
Removed the printhead, flushed the purge pads, cleaned the platen and timing strip and stored it.

To make place (and keep the wife happy) I will discard my last spare 9500II. Except for the printhead, I never had a failure with these printers.
