HP Pro6970 will not print cyan

[Effer]

my HP pro 6970 printer wont print cyan. i have tried everything that has been suggested before like resetting, changing cartridges, cleaning printheads.

i did notice that someone said they cleaned the cyan print head with some printhead cleaning fluid.

can anyone tell me how to do this before i throw the printer away.

Hi @Effer,

Welcome to the HP Support Community

I understand you are facing an issue with your Print quality HP OfficeJet 6970 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove the USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle
