re: filmscanners: OT: How to reset Epsons with "chipped" cartridges

[Alan Womack <arwbackup@worldnet.att.net>]

The epson status monitor does get ink levels from the printer/chip.  However, 
this is NOT stored on the computer.  The inklevel is written to the chip 
periodically.  This is proven by moving the printer to another computer or 
unplugging the printer without turning it off.  You will find the ink level 
follows the chip/cart.

It's not clear when or how often the printer reads and writes to the chip.  
After I reprogrammed it a few times with different carts I would occassioanly 
get a message that hey this isn't the same cart us it anyways?

The HP gets its ink from esitmating the use from squirts just as the epson 
dees, however if you took that cart out and put it back in, the printer will 
think it was full, just as the earlier epsons do.
