I have a power problem on three hp deskjet 1220c printers standing in the workshop, they go on but seconds later trips out again, all of them have new power supplies in???

They obviously have a excessive draw that is taxing the supply.

Disconnect the drum heater and see if they will stay up. You could have a short in the heater.

Sorry been working on too many lasers.

Make sure the head drive assemblies are not jammed and are free to move. If you can disconnect the drive motor for the heads and see if this changes things.

You will need to locate the excessive draw. Look for pinched wires. Dark components on the circuit boards.

Good Luck Lee
