Hp officejet pro L7650 all in one printing problems

probably best to use a different paper brand or grade of paper. try using a different feed if possible, there is usually 2-3 different feeds on these multi stations now days. (front, top and rear)

Sounds to me that your transfer kit may need replacing if your have toner

Try using the HP Print Diagnostic Utility in Windows - HP Customer Care (United States - English),

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.

To correct that problem better uninstall and reinstall the HP solution center and after that it should locate your working printer on your network...

verify if you have ink in yellow cartridge
perhabs you should change it

Hello sir; It need to clean up paper feed roller.

Are these new cartridges? If so, take the protective plastic off of the cartridge and reinsert them:)

Turn off mirror printing:
R-Click on printer
Properties --> Printer Preferences --> Advanced -->
+Printer Features - Mirror Image: OFF

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
