Ink Cartridge errors

[sdcomputers]

I have installed 4 new Cartidges into DL430 and status indicated 100% full

for some reason three of them are now showing 50% has anyone come across this

[Minilab service]

This drylab shows information from chips on cartridges. Probably wrong information there. If cartridge is full you can change cartridge chips or reprogram them ( using external programmer ) .

[uclbph]

where to get external programmer ?
