How to repair hp 6500 printer does not print color.

For severe HP OJ 6500/6500A/7000 print quality/missing color issues, or incorrect color output, there could be an air bubble in the ink cartridge(s), an air gap between cartridge and PRINTHEAD, or a portion of the PRINTHEAD is dry (quite common), so you should first perform a CLEAN PRINTHEAD procedure from your printer control panel.
It is first suggested you print the SELF TEST or PRINT QUALITY REPORT (under TOOLS menu) to aid in identifying which color is causing the issue. Check that cartridge or cartridges to ensure they have plenty of ink inside.
NOTE: If one or more the colors were previously dry fired during printing (i.e. if you continued printing using only a few colors to one, air may have been accidently ingested into the ink lines between the cartridge(s) and PRINTHEAD. To recover from this problem, you may have to run the CLEAN PRINTHEAD procedure 2-3 times.
If a problem persists then it is suggested to review the steps outlined on the following HP 920 support pages, including printhead removal/printer cleaning and service station cleaning. It is suggested you refer to printer manufacturer instructions first as the Inkjet411 procedures are provided for general guidance purposes only. A dirty service station can cause poor image quality and/or ink cross-contamination between different colors:

If the problem still cannot be corrected, then the PRINTHEAD may be dry and may need to be flushed (i.e. with warm water as it could have dried out, but this is a function of how much you print). Remove and thoroughly flush all ink ports for 2-3 minutes...thoroughly dry printhead prior to re-installing. Retest. For complete instructions refer to video here: http://inkjet411.com/?page_id=2412
Worst case scenario the PRINTHEAD may simply be electrically damaged or at end-of-life (while Officejet 6500/6500/7000 printer PRINTHEADS are rated for an estimated 15,000 pages, the average consumer may only see up to a 10,000 printed page throughput) and may require replacement. A severe failure of the PRINTHEAD is typically accompanied by error messages such as INCOMPATIBLE PRINTHEAD, REPLACE PRINTHEAD or INK SYSTEM FAILURE. NOTE: The PRINTHEAD will eventually fail in time. For more information on the how the PRINTHEAD works, watch the video here: http://inkjet411.retailinkjet.com/?page_id=1983
To verify Printhead electrical performance, activate the Tap 41 diagnostic test, (i.e. Pen Status: Pen OK).....for printer model instructions please visit: http://inkjet411.com/?page_id=1813

On HP 6500 printers, remove screen and try heating the connection elemants with hair dryer or something similar. Nothing to hot. The led bars should restore. Here's a link on how to remove HP 6500. Do same for 6500A model, but screen is a bit different, so check out the other video for HP 6500A and 6500A plus printers:

Worst case scenario the PRINTHEAD may simply be electrically damaged or at end-of-life (typically fails between 3,000 and 5,000 printed pages) and may require replacement, usually accompanied by error messages like Incompatible Printhead or Ink Delivery/System Failure.

Try soaking printhead in the cleaning solution and it will resolve the issue. Check out the video on how to repmve printhead below. Put it in about half inch of solution which is 50% water, 40% window clening solution like windex, and some ammonia or rubbing alcohol.

In all likelihood your print head has become clogged at the black ink outlet. Be aware that printheads can BURN OUT if you keep trying to print and there's insufficient ink reaching the printhead. The ink flow is relied upon to prevent overheating of the tiny resistors at the printhead. Best bet is to remove the cartridges from the printhead and then remove the printhead and try to clean it in warm water. You will find many youtube videos on suggestions for cleaning the printheads on HP printers. Do a google search for your model. If all else fails you can order replacement printheads for the part that has failed. They are not cheap so price compare. Oftentimes they will cost nearly as much as a new printer!

Hi,

The following may work: remove all the ink supplies. Remove the printhead and soak it for about 5 minutes in 0.5" of very hot water. Gently blot the printhead on a soft damp paper towel to remove the excess water, then replace in the printer and then reinstall the ink supplies.

Hello!

Please check the "Rplacing an ink tank" part of the manual. Hope it will help you.

1. Do U use "HP Solution Center" and if yes, do u see the cartridge in "estimated ink levels" window (if U don't, try clean the chip's pins on the cartridge)? 2. The "Photo Black" is pigment ink while the "Black" is dye ink.

Hi, When using refilled print cartridges, the Estimated Ink level and the Printer Status Window may indicate that the print cartridge is out of ink. Either continue to use the print cartridge until print quality degrades, or replace the print cartridge with a new HP print cartridge.

The methods of replacing the ink cartridge of the printer follows here:
Open the printer cover
The printer ink carriage will automatically goes to center
Once the carriage is in the center, the printer was ready to replace the ink.
Pull the down slowly the ink tank off the carriage..
Remember the place where the color/black position.
Remove each tank one at a time, and replace the ink with a new one.
Close the printer cover and it now ready to printer.
