Hi @Crady

 

Welcome to HP Support Forums. A really great platform for posting all your questions and finding solutions.

 

I understand that you are unable to print in Black from your OfficeJet 4622 and you have already tried cleaning the Printhead

 

I'd like to help.

 

Do you have an adequate amount of Ink left in all the cartridges?

 

Try printing a Diagnostic Page and let me know if the Black prints

  1. Load plain white U.S. letter or A4 size paper in the tray.

  2. On the control panel home screen, press the Setup icon .

  3. Press the button  next to the Down Arrow  until Reports displays next to OK.

  4. Press the button next to OK to select Reports.

  5. Press the button next to the Down Arrow  until Print Quality Report displays next to OK, and then press the button next to OK. The report prints.

    Figure : Example of the report

Try updating the Printer Firmware from Here

 

Also ensure that the black cartridge is properly seated and vented.

  1. Press the Power button to turn on the printer, if it is not already turned on. Wait until the printer is idle and silent before you continue.

  2. Locate the two slots on the left and right sides of the printer.

    Figure : Locations of the two slots

  3. Slide your fingers into the two slots, and then lift up to open the cartridge access door. The carriage moves into the access area.

  4. Press the tab on the front of the cartridge inward to release it, and then pull up on the cartridge to remove it from the slot.

  5. Locate the vent area on the top of the cartridge.

  6. If the cartridge still has the orange pull-tab attached, pull to remove it.

  7. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

  8. Image: Clean the clogged vent with a pin.

    1. Clogged vent

    2. With a straight pin, gently remove excess adhesive from the vent

    3. Unclogged vent

  9. With the nozzle and contacts facing down, slide the cartridge into its slot. Press down on the cartridge until it clicks into place.

Thanks....but......I saw this post from earlier and tried all the steps.  I really have.  All of them.  Every one.  Black ink still fails to print.  The  Print Quality Report has no black text anywhere....only the color bars.   It seems to ignorant me that there is a problem with the black print head.   Interestingly I have acquired an additional HP Officejet 4622 and have the interest, motivation and talent to remove workable print heads from one and install in the other.  Absent some other trick you may have might my approach be feasible??

Thanks for your input and advice.

Hi @Crady

 

I understand that the issue persists even after all the troubleshooting steps. This seems to be an issue with the print head. If you are comfortable replacing the Prinhead by yourself, you can, but it will void any existing warranty left on the printer

 

You can also contact our Phone Support for Service Options or Upgrade Options.

 

Step 1. Open link: www.hp.com/contacthp/
Step 2. Enter Product number or select to auto detect 
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click: HP contact options - click on Get phone number and phone number appear.

 

Thank you.

Thanks for your prompt reply.  Yes, I'm OK with voiding the warranty for my HP Officejet 4622.  It's a discontinued model  anyway and despite my several efforts I could not convince any HP support personnel to send me a schematic of the printer and instead tell me that : "It's impossible to remove the print heads."   Well, I'll show you.....

So here's how my afternoon went.   After only a little breaking of plastic  on the bad printer I discovered how to properly  and gently remove the upper case from the other, good  printer.  After only a bit of pondering and inspection I found how to remove the  bad printhead but ran into a lack of basic knowledge issue.  I did not realize that todays ribbon connectors now slide easily into a  ribbon connector fitting/housing mounted on the printer head electronics board.  Back when I did some electronics work only  a few decades ago it did not used to be that way. Oops, My bad.  I did not need a bigger hammer after all.  Bottom line:  Because of my damage to the "good" printhead I could not insert the ribbon connector which dashed my well designed plans.  Oh well,  at least you did not tell me that attempting this transplant was "impossible".   All in all it was a entertaining and relaxing project.  With all the appropriate legal disclaimers,  I can recommend that most any adult with sufficient patience and some small torx screwdriver bits could do an adequate job in replacing print heads if they know that three screws that hold the top housing are hidden behind the front display panel. A sneaky "gotcha"!   A schematic would have revealed that. Oh, be sure and look up how to replace ribbon connectors.   Thanks again for your help and advice.  I will now close this discussion.
