Enderfratze 0 Report post Posted May 7, 2021 Hello i purchased, installed and activated the chipless firmware (https://www.2manuals.com/product_info.php?cPath=107&products_id=1848) for my wf-7720 dtwf. after the update i cannot see text on the printer's menu and stuff, just the symbols... In addition the print results are just bad. Do you guys know what the problem is? I have a CISS system installed but it is not the problem. cleaned the printhead twice now and let all air out of the system. This is clearly not the problem Thanks in advance :) Share this post Link to post Share on other sites

Enderfratze 0 Report post Posted May 17, 2021 Unfortunately i cannot upload the image of the print quality.. But i can describe: There is no blue used. I think this might be an issue due to activation? I mean that in the Firmware there is some code that stops the printer from printing blue Share this post Link to post Share on other sites

Enderfratze 0 Report post Posted May 18, 2021 I did this. When i went back to official firmware the text was missing as well... And then i tried to change it back to your firmware but the problem keeps existing. Share this post Link to post Share on other sites
Enderfratze 0 Report post Posted May 18, 2021 Can this be an error due to activation failure? That in the firmware there is stopped that one color ink flows when its not activated to avoid copies? Share this post Link to post Share on other sites
Enderfratze 0 Report post Posted May 18, 2021 And i already cleaned the printhead twice and let all air out of system. Yesterday i cleaned the channel for the blue ink in the nozzle and it is open. Therefore it has to be in the firmware Share this post Link to post Share on other sites
wic.support 30 Report post Posted May 20, 2021 Good day. Chipless firmware does not have any code that stops ink flow at all, do you have the same problem with blue when using official firmware? Share this post Link to post Share on other sites
