Hi Yes you can try clean.

Ok it got to be the heads blockage
There is fluid cleaner for this but I can never find any in the shops the only ones I seen is when they sell them in Tesco but they come in with the ink refill bottles so I just use worm water by it self on a cloth and dabbing on the heads to clean them, it will not harm the heads but not to much water.

Some heads are on the inks them self but some have them inside the printer so I not know your printer so if the heads are inside you need to get them out you may find that some heads will just clip out put some need to be unscrewed so you got to know how they come out so be careful and not push to hard on them, if the heads are on the ink then it is a easy job to clean them,
It worth a try it worked for me more than ones.

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on Helping.

My HP Officejet Pro L7650 printer says "Cannot


Hi

Firstly you should check if there is any covering on the ink nozzles
Did you try to allign the print catridges after you changed the same.
Take out the catridges and clean it with a piece of cloth again put it back and check
if still it doesn't work
If you have done it perform a semi full reset:-
Unplug the power cable at the back of the printer
Press and hold down the (#) and the (6) key together pplug in back the power cable
Leave the keys it should say on the screen semi-nvm reset if it doesn't says so its not done properly .. try to do it once again after that it should align the catridges automatically
This should solve your problem if not try with a different catridge

I am unable to print on my HP Officejet Pro 8500. i have recently replaced the 940 black cartridge and since then have been unable to print. i notice there are print cartridges in the main body as well...


you can check the ink level from following steps Method one: Check the ink levels from the idle screen on the color graphics display Look for four icons at the bottom of the color graphics display. The icons represent the ink level remaining in each of the four color ink cartridges: black, yellow, light cyan (blue), and light magenta (pink). A larger and more accurate view of the ink levels can be displayed from the Setup menu. If an ink cartridge containing non-HP ink is being used, a question mark displays instead of the ink drop in the icon for that cartridge. The HP All-in-One cannot detect the amount of ink remaining in ink cartridges that contain non-HP ink. Figure 1: Non-HP ink iconc00841629.jpg NOTE: HP cannot guarantee the quality or reliability of non-HP ink. Printer service or repairs required as a result of printer failure or damage attributable to the use of non-HP ink will not be covered under warranty. If a hollow ink drop icon displays, the ink cartridge represented by that color icon has very little ink remaining and will need to be changed soon. You might be able to continue printing for a short period of time with ink remaining in the print head assembly. Replace the ink cartridge when the Replace Soon warning message displays on the color graphics display. Figure 2: Low ink level iconc00841630.jpg When the Empty Ink message appears on the color graphics display, the indicated ink cartridge is out of ink. Replace the indicated ink cartridge. Method two: Check ink levels from the Windows computer The estimated amount of ink remaining in the ink cartridges can be checked from the computer. See the on-screen HP Director Help for information on checking the ink levels from the Printer
  1. Open the printer Toolbox. To do so, do one of the following:
    • Open HP Solution Center, click the Settings menu, then point to Print Settings , then click Printer Toolbox .
    • Right-click the HP Digital Imaging Monitor in the tray, then point to your printer model name, and click Display Printer Toolbox .
    The Toolbox opens.
  2. Click the Estimated Ink Level tab. The estimated ink level gauges display.
Method three: Check ink levels from the Setup menu
  1. Press Setup on the printer control panel.
  2. Scroll down and select Display Ink Gauge . The Ink Gauge status from the Tools menu will only display on the color graphics display.

If the ink level is low and the cartridge is new please contact the dealer from whom you got the cartridge and if it shows that the ink level is good enough please comment so that i can give you another step to perform

HP Officejet Pro L7650 Print head problem


The reason why the printer refuses to print if you get low on one or more colors is that the system runs off negative pressure through the ink lines to the print head. If you were able to continue printing with an empty cartridge you could get air in the respective ink line, disrupt the negative pressure, make it so that that color will no longer print, and require you to get the printer serviced to fix the problem. I own a Cartridge World ink refilling store and I feel this is a good machine (compared to some of the others out there). The only down side with this type of machine is the print heads expiring or getting clogged as you are experiencing. The reason the black is clogged and not the other colors is that the black ink is pigment based and the colors are dye based. The pigment based inks do tend to clog print heads over time. You can try to rehydrate the print head with warm distilled water. if you can't get it working to your satisfaction you can buy a new black/yellow print head for $72. With this type of printer you should print at least one black and white and one color document per week to keep the print heads fresh. If they sit too long without ink flowing through them then they can get clogged and print poorly. I hope this helps belay some of the resentment you hold towards your printer.

Won't accept non-HP cartridge


You ask "Is this a common problem with non-HP cartridges? " It is a possiblity.
Where did you purchase the cartridges from?
This error might be caused by defective printhead or sensors

Are you removing the 2 protective caps from the cartridges?

Read this HP page:

My HP Officejet Pro L7650 prints yellow instead of black


Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
