HPOfficejet6950 Printer cartridge not recognised

[Paula_1]

I have a HP Officejet 6950 Printer which has been updated recently because I did not realize that the auto update feature was enabled.

Recently purchased compatible cartridges (which I have always used) and now because of the update the printer will not longer recognize compatible cartridges.

Is there any way to wind back the software update so that the printer will recognize the cartridges?

Thanks in advance for any assistance.

Reset the printer

• Reset the printer to recover from printer errors or failures.
• If your printer has a rechargeable battery, remove it.
• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.
• NOTE:HP recommends plugging the printer directly into a wall outlet.
• Turn on the printer to complete the reset.

Clean the ink cartridge and printhead electrical contacts

• Remove any debris or buildup from the contacts on the cartridges and in the carriage.
• Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.
• Remove the cartridge indicated in the error message from the carriage.
• Wipe the copper-colored contact on the cartridge with a lint-free cloth.
• 
• Place the cartridge to the side with the contact facing upwards.
• Wipe the contact inside the printhead with a lint-free cloth.
• 
• Reinsert the cartridge into its color-coded slot, and then press down on it until it snaps into place.
