Need Help Flexiprint basic / HP latex 310 color consistency

Hello, Any help or suggestions would be helpful. Our issue is with color consistency on our HP latex 310. We are printing primarily on HP everyday satin canvas and using the HP everyday satin canvas profile with 16 pass through Flexi Print Basic. We are experiencing a day to day change in color consistency with our outputs. We have tried a variety of other profiles with the same results. We have the media set for long run consistency on the printer. I am not sure what I may be doing wrong or if the issue is with the RIP or the printer. It is very frustrating. We run color calibration often and in general the color calibration box is always marked as OK. I am attaching a few photos that illustrate our issues. All four canvas outputs are from the same ripped file in flexi. The file has already be printed and in the rip, all we are doing is resending and we get a variety is color outputs. Our printer is located in a controlled environment with an consistent average temp of 74 and an average humidity of 40. This has been an issue we have been struggling with for over a year. The time and materials have been extensive. We have replace the maintenance carriage and several of the print heads one this time. Also I am printing out of Adobe CC on a Mac and sending over our network to our PC with Flexi on it. Thank you

 

I will look through Flexi, I don't recall seeing a setting to add the bars, but I will check. Thank you.

 

I did find the setting to print CMYK bars along the left and right sides. I will run some tests today utilizing them. Thank you!

 

Thank you for the input. No one seems to have a solution, least of all HP. I am feeling like dumping it as well.

Thanks

 

When it works, it works great but when it doesn't it is a real PITA. I have spent much more time on problems than anyone should. I have a few more things to try, we will see.
