hovuongchau 0 Report post Posted June 16, 2020 Previously I used 3 epson wf-7110 with chipless key. At first the machine ran very well. But after a period of use, the error "close ink cartridge cover". Accompanied by error 0x69, the printer cannot work. I switched to using 2 epson wf-7710 with chipless key. At first the machine ran very well. But after a period of use, the error "close ink cartridge cover". Accompanied by the error "034503", the printer cannot work. I don't know what to do, so I should ask the Admin for help. And I am very grateful. Share this post Link to post Share on other sites
wic.support 31 Report post Posted June 16, 2020 Both 0x69 and 34503 means: ink system clutch operation contact point detection error. i.e. printer unable to detect that cartrige cover is closed, we never had complaints like this before, let alone from the two unrelated models. I think the problem is with the setup of the CISS system or cartridges. Try to remove everything from the printhead, close the cover and check if you still see this error when it is empty.

hovuongchau 0 Report post Posted June 16, 2020 Many thanks admin's answer. Since I bought the chipless key I have printed a lot. No errors from ciss, I checked. I think Epson has done something to restrict users from printing a lot. I don't complain here. That share because error 0x69 and 34503 is very common and almost impossible to fix.

neozmaster 0 Report post Posted August 5, 2021 This error appears due to a breakdown of the pumping system mounts. Share this post Link to post Share on other sites
shouldberetired 0 Report post Posted September 30, 2021 Are you referring to the Printhead capping assembly? Some manufacturers call it the service station. Share this post Link to post Share on other sites
