Generally, this involves replacing the printerÕs old image processor board with a new image processor board. In the case of the Phaser 200e and 200i, the printerÕs engine control board must also be replaced with a new engine control board included in this kit. In all cases, the unused or replaced components must be returned to Tektronix. This upgrade should only be installed by qualiÞed service personnel.

Handle the circuit board(s) by their edges only. Do not lay the board(s) on a metal surface. Avoid wearing nylon or polyester clothing; they generate static electricity. s s s s s s Copyright © 1995 by Tektronix, Inc.
