Welcome to HP support community.
Is the printer coping fine?
Slow performance issue is only during faxing or for printing also?
Turn off Error Correction Mode setting
To turn change the ECM setting, open the fax menu, select Basic Fax Settings, Advanced Fax Settings, or Preferences, select Error Correction Mode, then select Off.
Let me know how it goes.
To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.
