Have already tried the following:
1. Use genuine HP zink paper (fresh pack)
2. Charge the printer (is at 100%)
3. Upgrade printer firmware (currently at 1.1.8, last updated 4 Nov 2019, using Android 9)
4. Clean output rollers (used the blue paper from the fresh pack to calibrate at least 10 times)
But the white line is still there.
Wasted so many packs over this and it's really frustrating.
Reset the printer using the below steps.
Make sure the printer is on.
Remove the paper cover.
Locate the Reset button.
With a paperclip or pin, press and hold the Reset button until the Charging Indicator light turns off.
The printer resets and turns off.
Replace the paper cover, and then turn on the printer.

My warranty’s over so I didn’t bother contacting the service center… But if yours is still under warranty I guess it’s worth contacting them to try!

Thanks for joining HP Community!
Could you please help me with the exact model name or the product number of the printer?
What device are you using the printer with, a Windows computer, Mac, Android or an iPhone?
Keep me posted.
Have a great day!
Hi, I have been having the same issues with my printer. Did contacting the service centre solve this? Wondering if I should do the same. Would love to know, thanks

I apologize for the confusion. Since it’s a Sprocket you do not have the option for Photocopy
Since you have already performed all the required troubleshooting, you can contact HP Support for Service Options or replacement
