It took at least 10 minutes for it to cycle through. Next I put the printhead back, then the ink catridges, which forced the machine to go through an intialization and alignment process. After waiting 15 seconds, I replugged the power cord into the back and waited for the error message: "printer error with printhead/catridges". While the machine was still on, I pulled out the printhead and ink cartridges (also cleaned them) then pulled out the power cord from the back of the printer while it was still on. HP Printers are notorious for not allowing a print job go through if an empty ink cartridge needs to be replaced.ĥ) What ultimately worked for me after completing the above steps was performing a HARD RESET. If you haveġ) performed a soft reset by pulling out the power cord from the back of the printer while it is still on then reconnecting after 15 seconds.Ģ) Cleaned the printed head (if it is removable, lift the lever and run the printer heads under warm running water then thoroughly dry.ģ) You may need to take a tissue of lint-free paper towel, dab some warm water on the end, and hold it over the ink release portion of the cartridge before reinserting into the printhead.Ĥ) Replace any empty cartridges.

I experienced the same problem with my HP 6500A Plus all-in-one printer and here is what eventually worked. What eventually worked for me was performing a HARD RESET as explainted in step 5 below after completing the other 4 steps first.

You don't want to get water in the flatflex connectors, so only use a small amount of water.

It's also highly unlikely I'll ever do it unless I get the printer for free and the owner doesn't want it back. I don't have one of these, so I can't repeat the procedure on a printer with a similarly mounted printhead like you have.

While my guide covers the cleaning process, it doesn't cover the required disassembly to remove the printhead on permanently installed printers. I fixed this on a removable printhead model and it printed perfectly after I cleaned the head this way. The problem is related to a clog you can't easily get rid of without physically removing the printhead and soaking it in hot water.

i suspect it is later, I will post update in future. I have a doubt whether this is actually blank ink or color ink is printing black color. However, when I print I can see black ink is getting printed. The printer still says it has not detected the black cartridge (because the LED light for black cartridge is constantly on). So after reading everyone post above, I also just applied clear masking tape on the complete contact points of the black cartridge and then inserted it.

I figured out for it to accept the Color cartridge I have to Reset the printer (instruction for HP deskjet reset is available on internet), however, it never accepted black cartridge, it always show Black cartridge Indicator LED blinking meaning it is not recognizing the refilled cartridge. In my old printer, I could refill old cartridge & keep using printer, but this new HP DESKJET 2135 never accepts refilled cartridge. I hope helps other I hv been fighting with my printer for 6 mon now
