To add to Jeff’s post, the instructions on battery replacement on this blog post on replacing the R3000 batteries make reference to removing the plastic chip holder, but don’t show how it’s done. It doesn’t seem to be hard, but there are a couple plastic tabs that I wouldn’t want to break.
In a recent post, Kelly stated that there isn’t much experience with these R2000 carts. That may be true, but the cartridge body is exactly the same as that on the existing R1430 / R1900 / R2880 carts, but with different chips. So you could use any of these carts from the other desktop top printers in the R2000. However rather than just exchanging the chips, you’d have to exchange both the chip and the chip holder, as the top of the holder is slightly different to accommodate the larger chip and battery.
Hence my interest in removing the holder, as it increases the availability of cartridge bodies for the R2000. In fact, when my R1900 eventually dies and I bring this new R2000 out of deep storage, I’ll be able to use the R1900 carts in use at that time in the R2000, after swapping the chips and chip holders.
