HP 6500 Office jet E709a - Black printer cartridge HP 920 not working [ Edited ]

[Shell741]

My blck ink is not out, the panel shows that it's about 2/3 full. But it won't print anything black. I turned the printer off and back on, and I remmoved the ink cartridge and put it back in. I don't know what else to do.

Please read this post then provide some details.  What printer model? Are the cartridges HP or refill/reman?  If HP check the date as shown here.  Is the cartridge years beyond its warranty date?  If refill/reman see here.

The printer ink doesn't expire until 2012. The other colors work, we uninstalled and reinstalled the printer, and we bought a new black cartridge. It still doesn't work. I am lost. any suggestions? Printer model is HP 6500 Office jet E709a. Printer cratridges are HP 920.

I would suggest the following:  first check the ink cartridge vents are properly cleared as shown in Solution 2 here.  After checking the vents run up to three cleaning cycles from the toolbox or printer front panel.

If the problem is still present then soaking the printhead as described below may resolve the issue. If your printer or printhead are still in warranty I suggest you Contact HP for warranty service as the following may be considered by HP to invalidate your warranty.

Read the entire instructions and prepare the necessary materials before starting.  The entire process should be completed in less than 30 minutes as leaving the printhead and cartridges outside the printer for longer may cause issues.  Be gentle with the printhead assembly, it is fragile and can be damaged by dropping or scratching the printhead.

Get a pan and put a soft paper towel in the bottom.  Fill with 2" of very hot (not boiling) water.  If your water is "hard water" then distilled water would be best.   Remove all the ink cartridges, then remove the printhead assembly.  Instructions for removing the printhead can be found in Step 2, items 1-5 of this link. Gently put the printhead nozzles down in the water and let it soak for five minutes [not five hours, not overnight....].  Remove the printhead from the water and gently dry the electrical contacts with a lint free cloth..  A clean coffee filter works well for this.   Do not touch the nozzle area.  Put the printhead back in the printer and then reinstall the ink cartridges.  After reinstalling the printhead and the cartridges you may need to run up to three cleaning cycles from the front panel or toolbox to restore proper operation.

I have seen some reports that letting the printer sit overnight can recover issues with black ink not printing after changing a cartridge.

Edit - I have seen variations of the above that suggest some alternatives.  I would specifically suggest NOT doing the following, for the reasons specified.  Although some of these may have worked for some users, they have great chances of causing damage.

Also, check the warranty on your printer.  If it still under warranty then Contact HP for warranty service rather than do the above procedure as HP might deny warranty coverage if you soak the printhead.

• DO NOT use alcohol or other solvents.  This may damage the printhead, causing the printhead layers to seperate, requiring replacement of the printhead.
• DO NOT use a Water Pik to force water into the printhead, this can also cause printhead delamination.
• DO NOT use a hair dryer to dry off the cartridges.  This could cause the nozzles to become dried out and clogged.
• DO NOT use compressed air to blow out the cartridge.  This can cause delamination of the cartridge and/or cause air to be ingested in the printhead.

 Note: the above applies to printers with individual ink cartridges and separate removable printheads.  Example printers include the following:

• » HP Officejet 6000 Printer Series - E609
• » HP Officejet 7000 Wide Format Printer Series - E809
• » HP Officejet 6500 All-in-One series - E709
• » HP Photosmart B8500 Printer series
• » HP Photosmart D5400 Printer series
• » HP Photosmart D7500 Printer series
• » HP Photosmart Plus All-in-One - B209a
• » HP Photosmart Premium All-in-One Printer - C309g
• » HP Photosmart Premium Fax All-in-One Printer - C309a
• » HP Photosmart Premium TouchSmart Web All-in-One Printer - C309n
• » HP Photosmart Premium e-All-in-One Printer - C310a
• » HP Photosmart C6300 All-in-One series

This printhead soak method DOES NOT apply to printers that have fixed, non-removable printheads such as the following:

• » HP Photosmart 8200 Printer series
• » HP Photosmart D7100 Printer series
• » HP Photosmart D7200 Printer series
• » HP Photosmart D7300 Printer series
• » HP Photosmart D7400 Printer series
• » HP Photosmart 3100 All-in-One series
• » HP Photosmart 3200 All-in-One series
• » HP Photosmart 3300 All-in-One series
• » HP Photosmart C5100 All-in-One series
• » HP Photosmart C6100 All-in-One series
• » HP Photosmart C6200 All-in-One series
• » HP Photosmart C7100 All-in-One series
• » HP Photosmart C7200 All-in-One series

We did as you suggested, and the printer says the printhead appears to be damaged. We did see a lot of black ink come off the printhead. A lot.  And there is still a glob of black on the printhead cartridge.

[Bob_Headrick]

You can gently clean the gobs of ink with a moistened q-tip.  Do not contact the nozzle area.  Clean the contacts on the printhead and dry the assembly before reinstalling the printhead.

Hi,

we have the same problem here at UCSC (cartridges appear full, but do not print color on the paper), but a different model: HP color laserjet 2840. Can you suggest something about that problem? I guess what you suggested on the officejet 6500 does not apply to us since we have a laserjet?

Thank you,

D.B.

I just tried the hot water and dried all the components and I STILL have NO way to print anything.  All text is invisible.

H-E-L-P! This has been a great printer up to now.

Seriously in need of printing ASAP.

That is correct, the suggestions here only apply to printers that use the 564 or 920 style cartridges.  For a laserjet issue I would suggest you post a new thread with an appropriate title such as "No Color Printing in Color Laserjet 2840".  Be sure to specify the operating system and drivers being used and details about the issue:  do colored areas print blank or do they print in grayscale?
