NOTE For the HP LaserJet 3392, disconnect one additional connector (callout 3) 3. Separate the power-switch PCA (callout 4) from the all-in-one to remove it. CAUTION PCAs are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when removing PCAs. Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part. Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the all-in-one. 1 3 2 4 Figure 5-38 Remove the power-switch PCA (HP LaserJet 3392 shown) 138 Chapter 5 Removal and replacement ENWW
