ReadFram 0 Report post Posted August 24, 2020 Hi Admin. I have a WF-C5790 and WF-7710, both of which are new, but when I boot up it says 031006, check on the software, the printhead fuse error is reported, but I use the nozzle through another machine to run normally. I don't know if it's Mian or what part Admin, ask for your help. Share this post Link to post Share on other sites
wic.support 30 Report post Posted August 24, 2020 What do you mean by this: "Check on the software, the printhead fuse error is reported, but I use the nozzle through another machine to run normally." Does this printer work under some circumstances? Please, explain with more details. 1 Share this post Link to post Share on other sites
ReadFram 0 Report post Posted September 12, 2020 Thanks for your reply. I have 2 of these devices which are new but when I boot up, I report 031006. I think there is a Main error, but I don't know if I have a fix for this case. Share this post Link to post Share on other sites
wic.support 30 Report post Posted September 12, 2020 So you have print fuse error and printer is not able to print, right? In this case you need to replace printhead. Share this post Link to post Share on other sites
