Hello all. I have been trying to convert a 9800 from OEM inks to PiezoPro. I have made a number of mistakes and also run into a number challenges, the combination of which have left me running low on ink while yet to make a single print! The latest challenge was a persistent missing nozzle in the Yellow channel which only showed up when loaded with the WarmLight. It can be difficult to spot gaps in the Yellow nozzle check, I should have looked closer before converting. I was advised that even a single missing nozzle can have an effect so I decided to swap the WarmLight (loaded in Y) with the GO (loaded in LLK) and then remap the curves, hoping that the missing nozzle would be less of an issue in the GO. But physically swapping the inks has been A LOT more wasteful then expected. Swapped carts and started printing purge files. After a while the ‘new’ inks started coming through, but even after about 60x220cm (24x86inches?) there still appeared to be ‘contamination’ from the previously loaded inks.
It seems to me that the new ink takes a lot longer to dislodge residue in the dampers than PiezoFlush?
In the end a combination of purge files and a full power clean seemed to dislodge most of residue from the dampers. Flushing out a channel and damper takes A LOT of ink. If I had to do it again I would consider ordering new dampers and changing those out as soon as the lines were fill. Feels like it would work out cheaper.
Is there anyway to confirm that a new ink has fully flushed and is printing “uncontaminated”?
Is there a way of printing a purge file or test image and then reading the print with a spectro to confirm based on numbers if the channel is printing ‘pure’?
