Thanks for the additional information, this is very important for me to help you get past this issue and back to happily printing. I am unsure why you say you aren't getting any kind of support from us, because I am certainly trying to help you, but as I'm not at your printer, I must rely on the information you provide in order to understand what's going on to determine the cause and solution for your problem. When you posted this thread, you had the option to be notified immediately via email whenever any posts were made to your thread, but if you didn't select this option, you would have to manually check the forum for updates to your thread. I leave the office at 5pm, and you posted after I left yesterday, but I am responding to your message as soon as I got into the office this morning.
If you have read your printer manual, ever spoke with Epson support, read about recommended conditions for use and storage of other inks and papers, you would realize that humidity is a HUGE factor in the function of your printer, inks and paper. But- if you ran your cartridge empty, then this has nothing to do with humidity.
If the cartridge was totally empty when you removed it to refill, then yes- you likely have air in the line, and this is what stopped that channel from printing. A cartridge can run dry before the chip indicated it needs to be replaced if the cartridge isn't completely filled when the chip is reset to full, or if the chip is reset without refilling the cartridge.
It is clearly stated in our cartridge instructions that the exit chamber must be at least 1/2 filled with ink for proper function, and if an exit chamber is less than 1/2 filled, you must refill the cartridge using the vacuum method to refill the exit chamber.
I believe you will have much better results and fewer frustrations if you read the information that comes with your products- printer, inks, cartridges, paper, etc...
If the cartridge was run dry, and air was sucked into the ink line, then installing any new cartridge (refill or Epson) will not magically make the VLM start to print again- no matter what cartridge you install, you will need to purge the air and refill the line with ink to resume printing. To do this, you will either need to do an Initial Fill cycle using the Adjustment Program, or download QuadTone RIP and follow our instructions for printing with the VLM channel to refill the line with ink to resume printing.
You can find our instructions for flushing an individual channel using QTR's Calibration Mode, here: http://www.inkjetmall.com/tech/content.php?144-Print-Ink-Separation-Image-thru-QTR-Calibration-Mode (you will want to follow the second procedure near the bottom of this page).
I hope this helps. Please let me know if you have further questions, how things go, or if there's anything else I can help you with.
Best regards~ Dana
