HP latex 800 printhead

Current optimizer head has a little under 500ml through it and the pin 4 black and cyan has around 5800ml. Has anyone had anything similar to this happen? No noticeable head strikes on media today previous to this happening. Print quality just immediately fell off mid roll.

Bit of a backstory here. I had an issue last month where the maintenance tray wiper ran out way before it should have and print quality got really bad. Replaced several heads before I finally figured out it was the wiper. I currently have 86% left on my maintenance tray. Im just unsure of what to do next. Thanks for any and all help in advance!

We're currently troubleshooting some horizontal banding issues and SCOURED the internet to find the true, printable HP Control Print for the 700 / 800 Series and FINALLY found it; this print is 'exclusive' to HP Service Technicians and it's what they would print to troubleshoot any issues.

The file is too large to attach, so please message me with your email address and we can transfer it to you.

It's a good starting point to hopefully identify and resolve your issue! We printed at 52" wide on the print setting with which we noticed the issue, as well as the highest resolution and passes (to eliminate the possibility of the issue resulting from lower passes/resolution). Good luck :)
