Step 1: Total distributions without restriction.
Each of the 4 distinct items can go to any of 6 persons, so there are
\[
6^4 \;=\; 1296
\]
possible ways in total.
Step 2: Subtract the disallowed cases (where one person gets all 4).
There are exactly 6 ways in which one particular person receives all 4 objects. Hence
\[
\text{disallowed} = 6.
\]
Therefore, the valid count is
\[
1296 - 6 = \boxed{1290}.
