Possible to Reinstall Epson R300 Cartridge

[Alan Smithee]

This is a basic question.
Once a new ink cartridge has been put in the printer, can it be removed
while mostly full and replaced with another cartridge? Can the first
cartridge be later reinstalled? Does the chip have a memory for how much ink
was in the cartridge? thanks.

Yes the cartridge may be removed at anytime, whether full or empty. The chip
will hold the information as to how much ink was used (theoretically though
quite often not actually, as the chip uses an estimate).
The cartridge may also be replaced with another cartridge and then later
replaced with the original one that was taken out.

What is also possible is to reprogram the chip with a chip resetter.
Folks do it often when they refill their cartridges (for those who do).

Thanks Jan. What I'm doing is a little "custom" mod. I'm putting a black
chip on a yellow cartridge (two yellows and no black! CcMmYY). The just put
all new carts in and I didn't want to lose two or three carts during the
experiment. thx again.

The answer to all of your questions is yes.

The printer cannot actually determine how much ink is in the cartridge,
it is estimated based upon your usage habits (estimated amount of use of
each color, as well as cleaning cycles). This amount is written to the
chip each time the printer is shut down.

Some people buy an ink chip resetter and refill their cartridges when
the run low, and reprogram the chip to read full.

I see Jan got to this before me, so our answers are pretty much identical.

Sounds like a rather "brilliant" idea... or at least a brilliantly
yellow one.
