Printing multiple black vertical lines

[GabiE-Xerox]

Hi,

In this case you really need a tech. It could be from the black LPH (Led Print Head), or (worst) from the ESS PWB (main board of the machine).

Sorry to hear that... that's unfortunate (and surprising).

I personally can't think of anything else to try. But if I do think of something, I will post again.

Good Luck!

Replacing the drum cartridge did not change anything.

@ mhv... Yes, start with replacing the black drum.

@gabi... nice catch! I didn't notice that!

[GabiE-Xerox]

Yes.

Correct that a power off/on did not fix the issue. So should I try replacing the black drum cartridge?

Hi,

It could be a problem from black drum cartridge (posiible discharge as per Andy indication), because from your image there is no image interruption on color mode (on lower of the page, cyan/blue text).

That is a strange one.

I assume this happens if you print out an internal config sheet as well?

I alao assume you have powered the machine off then back on.

My first impression would be an arcing issue (high voltage related (internal) - bad drum or ground issue within the machine maybe). Try reseating the drums to see if that corrects the issue. Also look for spilled toner (can cause electrical issues in the machine if it's in certain areas).

I will do some checking around to see what I can find out. I will report back with results.

Can you post an example of the page and defect for inspection?
