| Need | Recommended solution | |------|----------------------| | Use third-party toner | Buy cartridges labeled “100% HP chip guaranteed” or use a printer without Dynamic Security (older firmware). | | Remove HP Smart bloat | Install package via HP_LJ_MFP_137fnw_Basic_Driver.exe (no HP Smart). | | Block telemetry | Firewall outbound rules for *.hp.com , *.hponline.com . | | Force Win7 support | Use generic Class driver (Microsoft IPP Class Driver) – limited features but works. |

: Ensure you release and tap the Stop button quickly after the prompt appears. "Incompatible Toner" after patch

Turn the printer off, then hold the [Stop] button and the [Power] button simultaneously. When the screen says "Press Stop to download mode," release them and press [Stop] again until it says "Wait Image".
