wic.support 30 Report post Posted February 20, 2020 Chipless firmware is not available for XP-8xxx XP-610x XP-510x WF-4740 WF-28xx, cartridge numbers do not matter in this case, only firmware serie. As for WF-2865 WF-4725DWF and WF-4730DTWF, I suspect that their internal model and firmware ID is identical to those, that we have, if possible, check real model name as shown in the WICReset and post it there. 1 Share this post Link to post Share on other sites
