All HP Cartridges in Place But One Will Not "Clean" or Print
Replaced an official HP cyan ink cartridge with another official HP cartridge. The printer status indicates it is a full cartridge, but numerous printer head cleaning "drills" leave no no cyan ink on the paper. All other HP cartridges print fine. This becomes B&W-only printer if ANY of its ink colors do not reliably leave their cartridges and reach the paper. Unbelievably, HP seems to offer no tips to correct this type of partial non-printing issue that renders the printer close to useless.
