cartridge problem: "K" cartridge is missing or damaged

[ftelesf]

Printer recently substituted with a new (reconditioned) one from HP Support.

Instructions are to setup the new printer with supplied cartridges. Done.

I kept setup cartridge working during two weeks.

I had a 934 XL cartridge (dismounted, it never worked because old printer was out of order).

I thought to substitute setup cartridge with 934XL to avoid its clogging.

Printer was on (still printing few minutes before) i opened it.....printing head do not move to central position!

I switched off and then on again, i repeat opening upper part.....nothing happens.

I supposed to bypass that problem (and so i did) ordering a print, then, while print head was working, i opened upper part, catched the 934 "setup H".....print head went to right running end....i couldn't mount my XL cartridge!.

Head there is and remain: i didn't find any way to make print head moving and coming in the center.

I tried to print a file from PC: nothing moves.

Clicking on printer icon, it opens a window where:

-on top (first line) after the printer name  there is a warning:  "user intervention";

-(second line)  listed the file name waiting to be printed;

-(bottom line) can read "one process on cue".

Could someone help me?

Thanks a lot.

@ftelesf,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that you are unable to replace the cartridges of your printer as the printhead does not com to the center.

This issue could be a hardware issue with the carriage.

Let's go through a few steps to resolve this issue.

And here's the step by step guide for you in the link: http://hp.care/2fOhW1u

Let me know how this works.
 

You have a good day ahead.

Link, that you kindly sent to me, wasn't useful in my situation.

My printer is like new (printed 32 pages) and i make it "out of order", doing an attempt to change black cartridge while it was printing.

It absolutely hasn't any piece of paper among its mechanisms.

I wondered how to make the manager move the print-head.

I made some trials without any success.

By a mere chance, i move a little a black gear that we can see on left, low internal, part of printer.

When i abandoned my wishes to make casual trials, i switched off the printer while it was open......

I could see the print-head MOVING!!!!

Repeating the sequence, while head was passing by the center, i pull out electricity cord from the socket: all things stop

and i could replace black ink cartridge.

My 6830 now works!!!!

Thank you Rainbow23.

@ftelesf, you are welcome.

I am happy to know that the issue has resolved as you were able to install the cartridges after disconnecting the power supply when the carriage was at the center.
