Hi @Salinas05,

Welcome to the HP Support Community

I understand you are facing a print quality issue with your HP Office Jet Pro 6960  won’t print red. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Are you using genuine HP ink cartridges?
• Does the copy print out the same way? 
• What's the application you are trying to print from? 
• Have you tried printing from a different application or device? 

While you respond to that, let's print a Print Quality Diagnostic page -Post the Print Quality Diagnostic page here so we can help you further.

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
