Can someone please post the weight, preferably in grams, of a full P900 cart?  Ideally non-starter, but it sounds like that doesn't matter.

Thanks Cem.  I guess it would also be useful to know the weight of an empty P900 cart.  Can someone with an empty oblige?

My thinking was that if the P900 carts really are the same as the P800 / 38xo ones, then we could impute the usable ink by weight.  I think that the 3880 carts were around 142.7 gms full and 76.2 empty, a difference of 66.5gms.  We don't know the SG of the ink, but it's unlikely to be less that 1.  The accusations of too much ink left in these carts is well known.

If the P900 carts empty weigh the same as the 3880, a big if, then that's 45.3gms of usable ink by weight.  That's a much smaller gap to the nominal volume of 50 mls than for the 3880.  (Yes, I'm assuming an SG of 1 but it's the relative difference between P900 and 3880 that I'm really interested in.)

It would be useful to get an empty P900 cart measurement to verify or vary this estimate.

I'll weigh the cartridges again when they are empty. May take a few more days. I am in the process of making trial prints and profiling prints right now.

I've found myself really disappointed with the P900, mostly around paper-feed issues.

Big Negatives I've found:
  • 13x19 Matte Paper won't reliably feed from the top paper feed. Just refuses to grab.
  • Loading nice thick paper, like Epson's cold press bright through the front-loading mechanism takes 1 min 40 seconds (I timed it) with constant supervision. You can't just set it and leave, you have to wait for the slow-slow screen to come back for the next step.
  • The new screen is nice, but really slow compared to older models.
  • The error chime is not as loud as on the P800 (I turned it up to max) this matters in our busy/loud environment.

Things I like:
  • I have noticed what feels like slightly better color than a P800 for the same prints, especially in darker tones.
  • The display showing the time-to-print is really nice (though doesn't seem terribly reliable.

But the paper feed issues are really troubling; nothing really likes to feed 13x19 paper the P800 is prone to skew  but not grabbing it at all is almost unusable for me.

I've got just one of the P900s, but 4 P800s, a P5000, a 3880 and a 7900  the P900, fresh out of box, has already been the most trouble.

Pat,
You should check out Mark Segal's excellent and thorough review over on photopxl:
https://photopxl.com/the-new-epson-sc-p900-printer-review/

If you scroll down many pages, he clarifies a number of issues about paper handling for which the Epson manual  has no useful information.

Read that just now his experience is the reverse of mine. Ha.

From the review, "My experience indicates it is very reliable." (top loader for less than .5mm)

I can't get it to reliably take paper at all that way, and the front feed, while it works fine, is 4x as as slow as the P800 was at "getting ready." I should probably make a video of how bad this feed mechanism is for me. Maybe after the holiday crunch.

Still not buying all the fuss about the 900. The ink switch, not a big deal. New ink set same thing. Maybe for the at home printer it makes sense. Just too small with very expensive ink.
The great buy is a P6000 at slightly over $2000. You can buy 700 ml carts which are about as cheap as you can buy oem inks.
Gives you 24" printing capacity plus sheets and rolls are a snap to load. I think I may get one if I can find someone to take this oh so slow Z3200 off my hands.

Took a video today of the mechanism just not grabbing a single sheet.

https://youtu.be/JraIPtUWjhw?t=37

It works if you apply a little pressure on the sheet as it's trying to grab, but that's not useable for our production environment. I'm really disappointed in it, that and the general slowness of the interface makes me sad.

--

I'm looking for something like the P5000 but with better full-bleed capabilities; the P7000 is still single-sheet feed, and that's a non-starter for us. We can use the P800 with a 5-10 sheets in the top feeder and that's great.

Man this is disappointing. One of the reasons I was wanting to buy a desktop machine was to speed up my sheet fed printing vs my P10000 ...maybe not so much.
