I am having issues with a single 4900 replacement MK cartridge causing the entire right bank of cartridges being reported as faulty. The error displayed is “Ink Cartridge Error : Replace Ink Cartridge(s)”
[li]I tried replacing the chips with battery based replacement chips on all right side ink cartridges and that did not work.[/li][li]I tried using different replace cartridges filled with Flush and that did not work, would seem those chips/batteries might be bad also.[/li][/ul]
I am able to temporarily resolve the problem by inserting just the Epson OEM MK cartridge, then all the ink cartridges on the right side are recognized and work. I then replace the Epson OEM MK back with the MK replacement cart and the printer works fine until it enters sleep mode. On power up the same error occurs with all the right side cartridges showing error and need replacing.
