IPF650 first 2618, now white lines.

[fornerm]

Hello folks,
I have a question about an IPF 650, error 2618 came up, now the print head has been replaced, works again, but there are still stripes on the prints,
I have attached a test image, I was told that was before, so exclude the print head , on the nozzle test print they are all in the same place, nut print in Service Mode is different,
see appendix. Who can give a tip?
Yes I know, troubleshooting image says ribbon cable, main board, etc...
Maybe it's possible without investing even more money?
Thanks to all....

The real head situation in nozzle check is done from service mode.
The "nozzle check" from user mode "masks" some of the issues.

Judging from your nozzle check - Your head needs replacement.

If you recently replaced the head and still have this situation - you need to check operation of purge unit.
Replace the white caps that the head sits into and also the purge - ability to suck ink.

That is all to it

Peace...

Hello, thank you for your answer,I renewed the white caps when I changed the print head.I'm suspicious that all the missing parts are in the same place, according to the nozzle test.thanks in advance
