HP DesignJet T790
 
 My T790 show following message :
 
-The HP Ink Cartridge has expired. (all of ink cartridge)
- The HP Printhead has expired
 
First time the following message being detected, i replace all of the ink cartridge  and printhead with new ones. and then printhead aligment and processing being succesfull for test roll and print (might be override processing).
 
Afterall ,the printhead show no error,the message has dissapear.its look like condition being normal but the cartridge still notify its has been expired. 
I check the cartridge detail and the information say 
 
-status : expired
- waranty/expiration  : 2020/2/27 (in waranty)  
 
i was setup the prints date and time into current time but still no working at all.
