Photocartridge and colour cartridge

[anon_private]

Thanks for the responses.

Few general questions.

For a stubborn blockage could one run warm water from the tap over the printhead, or could this damage the circuitry?

People have said that after refilling one should never put anthing over the printhead. Yet if I but a cartridge it always has some tape ove the printhead?

Regarding dilution. Someone mentioned that cartridge flush is the best solvent to use, and that some ink vendors recommend this to create photoinks.

As a matter of interest, different companies produce inks for the same printers. Is there really much diffence between them. I understand that some are pigment and some dyes. Comapring like with like.

Thanks again for the info

Bests wishes
