No, but he reads every word here.The word is cold, he hasn’t posted here in an age.. There’s no money in it for him..
He’s lost to the dark side..
Yes he does visit, but only to pick juicy bits that he can use on his own channel later, on the other hand, Jose gives fantastic advise on photo printing and reproduction, but on the hardware side, his comments are all second hand and so old news..No, but he reads every word here.
The idea that Canon have left the door open on the Pro 1000 chips is all too premature, we had that said before about other Canon printers, which turned out to be wrong.but his theory is that the chip only is declared empty when the internal tank drops below a certain volume, so even if the counter is long empty, as long as you replenish the cartridges it continues without having to disable ink monitoring
I tend to agree, why anyone would want a low ink warning system installed is beyond me, because the carts hold 60ml plus of ink, and that’s a lot of printing, and it's so easy to refill these carts again.. No modifications needed.. There’s no danger to the print head..So Preciision Color's ink level warning system maybe isn't as superfluous as I thought.
I reckon this theory on sensors in the reservoir is all nonsense, the little pool of ink internally is just like a bird feeder with the up turned bottle, the carts just keep topping it off till there’s no ink left in the cart.. speculation is just that.. The world was once flat..his theory is that the internal reservoir of each color on the Pro-1000, has 2 sensors,
As far as I observed in the Maxify - and as @Artur5 proved by dissecting a printhead - the ink sensor in the Maxify serves only to protect the printhead, it raises an error then (cleared after placing a cart with sufficient ink - and a resetted chip I suppose).Not exactly, although it has some similarities. If I understood José correctly, his theory is that the internal reservoir of each color on the Pro-1000, has 2 sensors, One sensor on top marks full level (of the internal reservoir, not the cartridge) and the other sensor located at the bottom of that reservoir signals 'low'. He compares this system to the flush of a toilet.
When the level of ink in the reservoir reaches the bottom sensor, a valve connecting the cart with this reservoir is opened to admit ink from the cart, until the level in the reservoir reaches the top sensor and then the valve is closed.
If there’s not enough ink left in the cart to fill the reservoir up to the top sensor, then the printer knows that the cart. is empty.
