Pagewide XL4000 sold by Konica Minolta

[copyman]

Hi,

Is there anyway to change machine back to HP factory specs so it will accept HP 843 "A" inks? When the XL models are sold through Konica Minolta you have to buy and use their 843 "B" inks.

I see there are Ink chips sold from China but heard they cause problems. Has anyone tried these chips?

Would rather reset machine if possible. Perhaps firmware, etc.

Thanks in advance
