Epson 9900 Black not working

Hi all
I have a Epson printer 9900 with K7 inks.
The black print head is not working so I need to remap all the K7 Piezography inks in a new configuration avoiding the use of black print head.

Which one is the best solution in this case?

Another question: is it easy to linearize the new remapped configuration or is it better to ask Piezography for new curves?

I tried with this configuration but it’s not working, and it’s not clear for me how to use the right curves… any suggestion?

N_OF_GRAY_PARTS=7

GRAY_INK_1=OR
GRAY_VAL_1=100

GRAY_INK_2=C
GRAY_VAL_2=53

GRAY_INK_3=LC
GRAY_VAL_3=53

GRAY_INK_4=M
GRAY_VAL_4=12

GRAY_INK_5=LM
GRAY_VAL_5=12

GRAY_INK_6=Y
GRAY_VAL_6=5

GRAY_INK_7=LK
GRAY_VAL_7=5

GRAY_HIGHLIGHT=4
GRAY_SHADOW=8

GRAY_OVERLAP=10
GRAY_GAMMA=1
GRAY_CURVE=

Thanks,
Andrea

Dear Andrea. You need to re-map an actual Piezography curve (.quad) from the Community Edition curve-set.
