This instruction sheet provides the details for replacing a Phaser 220e's image processor board and I/O board with a 220i image processor board and I/O board. After installing the upgrade you must return the 220e image processor board and its I/O board to Tektronix.

Static precautions

Leave the printer plugged into its power outlet. This preserves a ground path for static discharges.

Touch the printer's bare metal frame often to discharge static electricity from your body.

Handle the circuit board(s) by their edges only.

Do not lay the board(s) on a metal surface.

Make the least possible movements to avoid generating static electricity.

Avoid wearing nylon or polyester clothing; they generate static electricity.
