I’m changing fully serviced / new headed 7900 over to Piezography Pro and have run into a problem.
The printer was working fully, and printed cleanly in color for a couple days after service. Once all seemed stable and good, I went onto convert it to Piezo Pro.
I did an INIT FILL to Piezoflush, and all channels are printing except for VLM which is now completely blank. The other channels still have trace color, but nothing serious. I’m pausing here to get some advice. What is the appropriate, safe and expert “next step.”
In the past I’ve converted more donor level machines - so would have just run the cleaning, power cleaning and/or an INIT FILL again, but have not really run into one going completely blank before - at least not one that didn’t eventually end in head death. Definitely not on something just serviced.
I now have some suspicion about the cartridge itself as I had a similar issue with another machine I just sold. It already had 2 other bad channels, so I was not focused on the VLM issue as it seemed par for the course and life of that machine. (I have one dedicated set of Flush Cartridges, but do use them between machines.)
The cartridges were primed and VLM is just over 1/2 full with Piezoflush.
