In another thread, Walker mentioned that the next batch of R2000 carts will be ARC. ARC carts make some sense for the R3000, but they’d be a pain for the R2000.
In the R3000, you need to regularly remove the carts to agitate them, and in doing so it was possible to accidentally short the two little reset pins on the chip, causing the ink level to be reset. If you didn’t notice this and top up the cart, then there’s a strong risk that you’d run out of ink, which causes a world of pain in an ink lines and damper printer. Moreover, the carts are larger so there is more time between the auto-resets, and most importantly, the auto-reset [I]doesn’t[/I] trigger a head clean in this style of printer.
None of this applies in the R2000. You don’t need to remove and agitate the carts, as the head moving back and forward does this, if you print at least once a week. Auto-resetting a chip [I]does[/I] trigger a head clean, so you’re endlessly auto-resetting and refilling and getting an endless series of staggered head cleans.
I understand the problems that the little batteries cause, but the R2000 is the one printer where they make sense. IJM just needs to better educate customers, perhaps even including a set of batteries with the carts.
[This is all written on the assumption that there wouldn’t be a chip resetter for R2000 ARC chips, like there is for the R1430, R1900, R2880.)
