I have an R1800. I am getting faint output from one of the carts and after several cleaning operations did not correct it, I bit the bullet and decided to do some maintenance on the printer. I followed the directions in the desktop maintenance video and cleaned the points in the print head with piezo flush and followed that by using the flush cart to clean the print head. After that I put the carts back in and ran a nozzle check and cleaning. I kept following the on screen directions and the nozzle checks were getting better. As I was doing this, I started running out of ink in a couple of carts and replaced them as I went. I then got a low ink on the magenta cart and replaced it. I had reset the replacement cart before inserting. After inserting the cart, I then got an out of ink light on the magenta cart. I reset the replacement cart again but got the same result. I powered off the printer but when re-powered I get the same out of ink indicator. I refilled the first cart, reset it but still get the out of ink light. So two full carts, successfully reset the chip but the printer still indicates out of ink.
Has anyone encountered a similar problem?
