HP ENVY Photo 7858 printing quality issue

[NotaHappy]

1 out of 20 pages prints ok, the rest have lines and are missing sections. I have reset the printer, cleaned it... and changed the ink.... this is a new printer... probably printed 100 pages total since buying it, and it's never worked properly... maybe only in the begining the first month or so.

I have tried everything and the printing is just getting worse. I have lost all hope in this printer... is it possible that this was a defected printer? There is literally no reason why this printer should not be working. We have literally used it less than 10-15 times printing standard things.

I suggest you do a Hard Reset on the printer

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

I'm trying to set up this brand-new printer and can't get through the initialization process.  After shooting out @30 mostly blank pages, the printer tells me to load plain paper.  I've gone through the reloading process about 5 times and I am totally frustrated.  How do I get past this point?
