Power-switch PCA
1. Remove the right cover. See Right cover on page 100.
2. Disconnect two connectors (callout 1), and then remove two screws (callout 2).
NOTE: For the HP LaserJet M2727nfs, disconnect one additional connector (callout 3).
3. Separate the power-switch PCA (callout 4) from the product.
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 product.
