"Occasionally, chips can not accurately track ink levels, in which case the chip is replaced. Again, this is not a common problem, and I have experienced very good ink level tracking with dozens of sets of carts I've used in our printers, as long as I refill carts when I reset the chip."
- I really look forward to using these again since I love your ink and what you guys are doing. I reset 8 cartridges using the reset chip provided., this then blinks red and turns red, and does not turn green with the exception of one cartridge (cyan). I did not try to reset # 3 and 4. What would you like me to do? Do I need to replace the chips?
"What channel(s) were you experiencing clogging with?"
- Different nozzles, after cleaning pairs, and printing a nozzle check, sometimes the same, sometimes different color nozzles would be clogged up. Occasionally there would be no clogged nozzles for three prints or so, after which it clogged at least one nozzle again. This would repeat itself add-infinitum until a whole channel clogged up and never came back, at which point Epson came and replaced just about everything to do with print heads, assembly etc. After which this whole process started again, same issues until I switched to Epson inks, and no clogging at all since, which could be a coincident ofcourse!
For example: in the middle of printing a large job, 15 of 40' long 30" wide rolls, every few prints or so a nozzle would be clogged. This with the correct temperature and rel. humidity of 40%. When asked the Epson tech remarked that this could not be due to dust since this was absolutely the cleanest 'print shop' he had ever visited. He also suggested Epson sent me some replacement ink since he said I had 6 full maintenance trays just from the nozzle checks and cleanings, Epson did not send replacement ink since I of-course had not used their ink while doing all this. He also switched of the auto-cleaning or repeat cleanings that the 9900 did when nozzle clogs were detected.
"Was it an entire channel or a few individual nozzles that were missing?" see above
"Did the missing nozzles come back after a few regular cleaning cycles?" see above
"Did you prime the refill cartridges before installing into your printer?" Yes. And, this initially was all setup by someone that worked closely with Jon, that trained at your workshops and that highly recommended your inks. They wrote to Jon/Wells as well, in private, after they started to have issues with the new cartridges etc.
Let me know, I would love to try and use your piezography inks as well, plus the over gloss, in fact really looking forward to this, I got over my initial disappointment and we just need to find out a way to make this work.
Thanks for your advise so far!
