Officejet V40 will not recognize black cartridge. Either says it is incorrectly installed, or that I have installed the incorrect cartridge. New HP 15 does not help. #6 reset did not work. Rebooted, cut V40 off for a while, don't know what to try next. Any thoughts? Thanks, Tom

Hello,

Your printer may need to be reset.

* Turn on your printer and re-install the old empty printer cartridges

* Wait for the printer to finish its cycle for recognizing the printer cartridge.

* Turn off your printer and unplug it from the power source.

* Clean your printer head and the electrical connections of the new printer cartridge. Be careful if you have already tried to install this prior since the ink may run.

* Plug back the printer into the power source and turn on the printer.

* After the printer has warmed up, do the normal process of installing your new printer cartridge.

If this doesn't work, it could be that the printer cartridge is faulty. Take the printer cartridge, its box and the receipt to the office supplies store or computer store where you purchased this and ask for a replacement, explaining the problem.

I hope this helps.

Hi, please find the solution of your issue on below HP website: http://h10025.www1.hp.com/ewfrf/wc/document?lc=pl&dlc=pl&cc=pl&product=14438&docname=bua02058

change the cartridge

Just replace the black cartridge with new one.

You are putting a defective or the wrong cartridge in.

Try some of these steps:

If it doesnt work then try with an original cartridge ,some printers don't like refilled or the refilled is not a good one.

I'm not sure if this will help but I aligned my cartridge's 5 times then the red exclamation point light stopped to do this hit the setup key #5 (maintenance) then hit # 2 follow instructions... to print full menu settings ..setup #1 then # 4 follow instructions

did you try changing the color cartridge too? I had problems with ink cartridges that were not HP cartridges.( not made by HP but some other co.)

you may need to do a clean heads and nozzles on that HP..try that first.
