Officejet 4620 will not print black

[BPete]

Installed new genuine cartridges, followed all cleaning, aligning etc suggestions.  Printer will not print black.  Colours appear fine.  Tried on/off etc - no black ink printing.

Using the copy option from the front panel do you see any black ink on the copy?

[BPete]

Just a couple of partial letters/lines, nothing correct.  I have tried the alignment and second stage cleaning options.  Any other suggestions?

The black ink clogged, try cleaning the printhead again.

Is the printer warranty over?

Black Cartridge not clogged.  Warranty over.  Bought a new printer.  Thx for the help even though nothing worked!!

The black inkjet on the printhead is clogged.

Since the printhead is fixed you can try soaking it from the bottom.

Youtube has many vids on cleaning a fixed HP printhead.

Are you kidding me?  I purchased HP for a reason, this is not it.  Where the hell is the real support that used to be available.  I can barely move the printer let alone soak the printheads.  Thanks for nothing.

I tried flushing out the heads with alchol with no black printing working at all still.
