With these newest style-refillable carts that don’t need vacuum filling, e.g. the ones I just bought for my 2880. What is the correct refilling procedure if a cartridge has (heaven forbid) been allowed to run dry, or (heaven really forbid) drained itself mysteriously, as might happen if the refilling procedure was not followed correctly? Do you think that the vent hole needs to be plugged in such circumstances? Would a vacuum fill be a good idea?
We’re supposed to let the carts sit in the printer for say 15 minutes after inserting them after refilling. Does this apply any time the carts are removed and reinserted? For example, if I move the head to the ink exchange position and remove the carts to check on the ink level, should I let them sit for 15 minutes before I press the ink button and trigger the nearly inevitable head clean? Likewise, with the cover to the cartridge area removed, it’s possible to remove and reinsert 6 of the 8 carts with the printer off - should I wait 15 minutes before turning the printer on again?
The R1900 and R2880 are essentially the same printer as I understand it. Does this mean that I could use an (unused) refillable for one printer in the other after replacing its chip with the correct one?
