When the Federal Reserve is issuing money, they are only printing cash money (coins and banknotes)?
If not, then what other types of money they are issuing?
Deposits at the Federal Reserve largely count as money, at least as far as the depositing commercial banks are concerned.
Apparently on March 1 2016, the Federal Reserve Banks' liabilities included $\$1475$ billion of Federal Reserve notes, net of F.R. Bank holdings, and $\$2530$ billion of deposits, together with $\$412$ billion of other liabilities. See the second part of table 5 of https://www.federalreserve.gov/releases/h41/current/ for more details
Coins are not issued by the Federal Reserve, but by the United States Mint
