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

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.

Machine puts a 1/2 inch black line down the right side of paper being printed


Replacing the ink cartridges usually fixes this problem. If there are still lines, try replacing the drum(s). Most drums however are self contained in ink cartridges on higher end printers and laserjets.

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?

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
