Printprism: I have bought it to test its capabilities and quality of the rgb profiles

Yes, I know. But space on my desk is limited ! By the way, I bought PrintPrism and made profiles with the XP-970 and the result is excellent. Specifications of XP-970 et ET-8500 scanners are exactly the same on Epson website: I am pretty sure they use the same hardware.

OK good to know. So you use the ET-8550 scan engine of the PrintPrism to generate the profile. Maybe Mike Chaney would be pleased that the XP-970 scanner has the same results because it uses the same scanning engine.

That is strange: I tried to use my Epson WF-7840 scanner if it would give a good profile (officially not supported) and to my astonishment the profiles are almost the same:

I tried the WF-7840 printer as scanner and using the ET-8550 scanning engine in PrintPrism:

Beneath softproofing with a PrintPrism generated profile: left with my Epson WF-7840 (not supported) and right with the supported ET-8550....They look similar to me.....

Now the 3D plot on iccview.de:

test.icc is the profile made with the officially not-supported WF-7840 scanner:

This is very surprising to me....Could it be the WF-7840 is using the same scanning hardware als the officially supported ET-8550 ???

Yes, exactly. There is no scanner restriction. I choose Printprism ET-8500/8550 option and when the Scan2 window open, I choose XP-970 scanner. Problem is I cannot compare my results with those of an approved scanner. I just can tell that the results with XP-970 are good. I do not know if they are as good as possible unless I buy a Canon Lide 300 or an Epson V39II. So maybe it is too early to tell Mike Chaney to put the XP-970 on his list of approved scanners.

I am sure that there is not that much different scanner hardwares around ! Business is business. If one hardware fits all, it is all benfit for the company !

However, looking at the spec Of the WF-7840 scanner on the Epson website, it not execaly the same specs: (2400dpi max instead of 4800). But it does not mean that the hardware is different.
