Ignore scan count. It is not the number of times a table has been scanned.
As for the high logical reads:
Large table
No indexes
Non-optimal execution plan
Poorly written query
Poor table design
Pick any one, or more.
With no context, no query, no execution plan, no tables, there's no way anyone here can do anything other than guess blindly.
