How Can I Scan with Networked HP Multifunction Printer

Running LEAP 42.1 with KDE Desktop.
I need to get my HP Color LaserJet 2840 multifunction to scan and cannot get started. Please could somebody point me in right direction. The printer is network connected and prints OK. I have hplip installed and a device manager is available in my tray but this does not offer scan, only fax. Grateful for help please.

SOLVED. Scanner not set up correctly on this machine but once done Skanlite worked OK. Trouble is I now have lost ability to print. Will do new post.
