Thanks for the update Robert.
Do you have washers on the air inlet points of any of your refill carts? Does your printer's pressure pump turn on frequently after installing the refill carts?
I am not certain what you mean when you say you inserted a rod into the cart to draw ink out, and there was air in the cart- did you insert the rod into the fill hole to the body of the cart, or into the exit chamber? There should be some air in the cartridge for proper pressurization and ink flow- do you mean the air was in the exit channel or main body of the cart? From what you say, it sounds like ink easily flows from the cartridge exit channel when primed, but you say NO ink is printing from the C channel with the refill cart installed (though it prints perfectly with the Epson C cart installed). These facts show 1. the printer's C channel is working correctly and you're not dealing with a clog, and 2. something with the C refill cart is restricting flow. If there is not a good seal between the cartridge and printer, in both the exit channel for ink and air inlet point for pressurization, then ink will not flow correctly (or not at all). If your printer's pump is running more often with the refill C cart installed then with the Epson C cart, then I suspect there is not a good seal between the printer and cartridge's air inlet point, in which case a washer will help seal that connection for proper pressurization, which controls ink flow.
As I pointed out when we spoke on the phone last week, Wells is our sales manager, and sometimes tries to help customers if they have issues and call for help, but is not technical support, and does not have the experience or in-depth knowledge with our products as I do. For the best and fastest resolution of your issue, it is important that you follow our support guidelines and contact techsupport for help- this will get you back to happily printing ASAP and avoid the waste of ink that you have experienced. Wells was only trying to help, and I appreciate that, but does not know to all the questions to ask or how to interpret the facts as I do.
During our phone conversation, you said this printer was serviced about a year ago by an Epson tech, but did not know what was done, nor have you cleaned/maintained the printer since. Do you have the information as to exactly what was done last year when the service tech worked on this printer? Those details would be very helpful to know. Regular cleaning is preventive maintenance and important to ensuring the best quality output and longest life from your printer- no matter what inks are used. Epson doesn't supply information about printer maintenance because they want you to pay their service department, or just buy a new printer. We have a great deal of experience and knowledge with Epson printers, and maintain all our own machines. One of our main color production printers is about seven years old and still running strong, producing flawless prints
We may be able to help you in regards to the ink wasted in troubleshooting this problem, but first it's important to determine and resolve the cause of your problem and get you happily printing.
Please let me know so I can help.
Best regards~ Dana
