black ink not working

HP Officejet 4620

Hello, 

 

I have done all the troubleshooting for the printer as in the page.  done the two step cleaning, hard reset, change cartridges, etc... and now just the black is not working..( on a test page, nothing in back appears) also photocopy doesn't work.. I guess I could manually clean, how do I do that on this printer? any other suggestions ? 

thanks

The troubleshooting steps in the document here may help resolve black not printing on your Officejet 4620.  

 

If the standard troubleshooting did not resolve black not printing I would suggest removing the black cartridge.  Turn it over and examine the area around the ink port.  There are four orange plastic spots, left over from the protective cap.  Make sure these are flush with the cartridge body, if not carefully trim them flush.  If the plastic nubs protrude they can prevent the cartridge from seating properly.  Before replacing the cartridge in the printer dribble a few (maybe four) drops of hot water into the ink port in the printer and two drops into the ink port on the cartridge then snap the cartridge back in position.  

 

It may also help to manually clean the printhead as described in the post here.

 

I have also seen cases where leaving the printer overnight after the cleaning cycles allows black to recover.

 

If none of the above restores black printing your printer will likely require repair or replacement.

Thank you for the suggestion.  I manually cleaned the printer. 

Unfortunately, I still get test pages without black color at all - not even a single dot-. 

 

Any idea how I can get the printer repaired?  It is clearly an issue with the dispensing of the black ink as I have done all the other tests and color printing is very nice and clean.

From a post by Sunshyn2005, to contact HP Support see the following link to create yourself a case number, then call and it may help speed up the call process:


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 on: HP contact options - click on Get phone number
 
Case number and phone number appear.

 

If your printer is not under warranty it is likely more cost-effective to replace it.
