I don’t mean to pester, sorry if it appears that way. I’m curious if you’ve tried OEM carts to see if you still get the blobs?
To Jon, if he’s listening…
If the aftermarket carts are aggressively vented, is it possible to seal up some of the venting on the cart to make it less aggressive? I’m paying close attention to this thread because I, too , use the R2000 which uses the same physical carts as the R2880, another popular piezography printer.
Also, are there any physical differences between your aftermarket R2880 and R2000 carts? Could the R2880 carts be designed to work better, and all we have to do is transfer an R2000 chip?
Because the printer is alternating between air in the print head (clogs) and blobs of ink on the paper… these signs point to the clean/flush box as the source.
The easiest solution is to buy another brand of 3rd party carts and see if it solves the problem. If it does - we retire the thread. If it does not - then look at maintenance focusing on the capping station area and below it.
