I purchased a used Epson 4900 from another screenprinter earlier this year.
I recently purchased an complete set of refillable cartridges and a gallon of UV45 Silkscreen ink from your company. At first, I only installed a few of your cartridges to replace empty or unrecognized cartridges. I had no issues with any of the initial cartridges I installed.
Yesterday I decided to replace all the remaining cartridges with your cartridges. I ran into two issues.
First one is my fault. I was installing the MK cartridge and a plastic piece broke off. I may not had it aligned properly and/or pushed too hard. A small piece of the plastic tab that seems to be for aligning the cartridge properly broke off. Can I buy the plastic tab from you?
The second issue is the LK cartridge is not working. Prior to replacing the remaining cartridges yesterday all heads printed fine on the nozzle check pattern. After installation All heads printed fine except LK. LK is totally blank. I did a manual cleaning and repeated machine cleanings. It is still totally blank. I read in the form that air can get in the head if ink is completely run dry before installing a new cartridge. That was not the case. There was till some ink in the cartridge I replaced. I also read that your Piezo flush may fix the problem. Please let me know what you think the problem may be.
If I need the Piezo flush system do I need to order the fluid and a cartridge or can I use the cartridge I have? The cartridge I have is already filled with UV45 ink. Do I need to remove the ink and replace it with the flush?
Thanks for your help.
