That doesn't mean the nozzles are not clogged, it also doesn't mean that you don't have weak nozzles. Doing a nozzle check before and after printing a solid block of color would help see what the issue is. A printhead with weak nozzles that has been running thick ink or struggling with ink flow for awhile will slowly weaken the nozzles in the printhead until it can no longer create the suction needed as the piezo crystals weaken. Eventually they will not be able to overcome the suction required to open the damper. This is why it works after a head clean until that initial pre-load of ink is dispensed and it starts struggling again. It's either a weak printhead, bad quality ink, poor quality aftermarket dampers, or something to do with your ink system. Could be poor sealing at the damper port and a busted printhead seal from improperly flushing the head. Hard to tell which without seriously digging into it. I learned long ago with Epson's it's best to stick to OEM dampers. Use a high quality ink, and make sure you clean any cartridge ports often, replacing them as needed if they have screens in them for the cartridges. That is an old printer, so I wouldn't be surprised if it's just tired, especially if you have used it for any amount of time with the thicker aftermarket inks.

laci Posted June 10, 2023 Author Share Posted June 10, 2023 i bought the printer second hand, with around 500 prints ( when i bought it was the capping station faulty , not sucked the ink properly so i changed it , when i bought it i run 2 nozzle check all nozzles was perfect.. and when i suck ink with syringe to damper and i do a nozzle check everything is perfect. so thats why i say my nozzles are not clogged Quote Link to comment Share on other sites More sharing options...
