I’m wondering if there is a way to flash the firmware on a 9900? The only comment I’ve found with an online search is that it can only be done by a repair shop and is not available online as it is “too risky”.
I’m willing to give it a go as a last effort to resuscitate a 9900 with a weird issue of a channel’s nozzles printing in reverse order. I’ve been told it could be corrupt firmware, but wondering if there’s a way of re-flashing it.
Any knowledge/experience of this, @walkerblackwell?
Thanks for your help!
