micro banding

Wrapping hose with metal tape to increase "grip" reliability! I will remember that.....

So now I'm printing again..
I do this post because I saw many issues with purge unit for i9950 and i9900, but people thinking that head is not all right (like me in beginning)
And what I read about, when some group off color dies, they bought new head and same thing, and throw printer and new head in garbage...
with lot of frustrations.

Well done @Saphire and I agree with you 100% because this is an ongoing problem with these printers and I thank you for highlighting the problem.
A nice fix with the aluminium tape…

Thank you for the aluminium tape tip and the nice photo series. Also thanks for confirming that the druckerchannel.de instruction also applies to the i9900. Well done

Congrats and thanks to attract attention to the purge unit.

I appreciate yours goods reaction on my last post. And I don't know yet is tape a good tip. For now it is ok. I always putting water in purge with some bad felling that will be soaked, but is not.
My printer still having badings like on beginig. That means that purge unit failed when I was put new head.
Now, seller was check new head and it is ok and he shipped it back
Yesterday was also come spare printer (blinking5 times orange head defect) so now have it for parts.
But what is in mine mind, whean new head come I will put it in printer that is work now. Old head, I will gamble, and put it in the that spare printer to check it.
I can loose old head, or
I can win new printer.
Btw I think that new head will overlive printer.
If don't I will buy again new head.what you think?

"5 blinks" are most likely printhead by itself.
Printer defect is rare, but I have got one motherboard (from MG5250) with Error U052 when printhead is present.
It is because some circuit failure (to be precise - temperature control circuit).
"5 blinks" may be also because of printhead EEPROM failure.

Ł.

I can tell you that 5 orange lights is always the same problem on a printer it refers to no print head installed or defective so you’ll need to get another head and then the printer will work again..

Today came a new head... and with new head there is no micro banding...
Thank for advices from beginning, you advice me to buy new head
Spare printer now is working with old head, 5 time orange is really only head problem, you have right again
So for end, I think from all this troubles from banding to purge unit I got some profits....2 working printers. I would never bought spare printer if I haven't problem with purge unit.
Now I should buy new head for spare printer . and spare printer for spare printer...
