[abozakaria]

Hi i have z3200 for long time
i notice banding starts from the middle of the photo for 3cm then gone then return bigger then gone then return for the end of the print
i printed the test image from menu with no banding
so i create a test image with one site has a photo and other sides i put bands of different colors
 i noticed when banding starts it only occurs in grey strip
i changed the printhead same problem
what to do

First things I would do are, shake the ink cart .  If it’s very low replace it.

Do a head alignment on the paper you are using.

Do a paper advance calibration on that paper.

Relinearize the paper ( hp calls it calibration).

Make sure you are printing at unidirectional , highest quality,

Print out rectangles of gray after doing all this to see if it’s still there and not image dependent.

I have issues with HP Premium gloss and other gloss papers as well.

i would suggest to print some more to put some ink through the heads.  ( and once a week) ..
if it does not go away do a diagnostic print and clean the dirty heads through the menu...
If that does not help do a manual clean ( be careful)
repeat.  Something like that.

do you mean you changed the ink cartridge for a new one and printed so much that the ink in the printhead was replaced by new ink?

No
Disassemble the printhead take away all lg ink and put new lg ink then i take away all lg ink from tubes and put new ink cartridge then pull air from tubes then make a printhead clean then print banding gone

wow! Never done that before!  well done! Sounds like a very delicate difficult operation.
I once opened a printhead to discover how complicated it looked and think i could not get it back together again.
-
I guess the same result could be by buying new ink- print some LG to drain the tubes and then buy a new print head...
