If your black channel can not be used - then its not difficult for you to remap the curves yourself. We charge $100 to do it for you, or I can tell you how.
Selenium Shade 1 black is our neutral universal black and you could install it and do a Piezography 2 on the printer where we reduce it to six shades of black and also a Gloss Overprint.
We first formulated Universal Black in 2005 for Roland which used it and four additional Piezography shades along with Epson C, LC, M, LM, Y, O & G to form their 12 ink Giclée printer. One black for both matte and glossy. We've changed it a few times since 2005 and we now call it Selenium Shade 1 (but it's neutral) - and its specs are a bit better than the warm version Photo Black. WN1 is opaque for film - and is warm with non-Piezography use - such as single black or with StudioPrint. Here are the 100% patches from Calibration mode in QTR:

Running Sel 1 as a Universal Black would give you a dynamite system and we have K6 curves for the 3800 / 3880. Also have them now for the 7800/7880 or 4800/4880 - even the R2880. anyone losing channels and we can usually help...
