Need Help Dx5 printhead is printing black band

[cs-creatives]

Hi,

My Dx5 printhead is printing black band.

I changed motherboard, headboard, head, cable head, long cable flat, optical fiber

it's always the same thing I do not know what to do.

head flat cables
try to disconect and conect better change them right now, maybe already the head blown out if you can’t see colors any more

don’t turn on the printer before verfifying the head flat cables

before disconect flat cables disconect printer from outlet and discharge capacitors (turning on the printer with no conection)

I can't really tell from your photos, but it looks as if your material is buckled pretty bad.
