Removal and replacement strategy

This chapter discusses the removal and replacement of field-replaceable units (FRUs) only. Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to provide directions for difficult or critical replacement procedures. HP does not support repairing individual subassemblies or problem solving at the component level. Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its original location during reassembly. Incorrectly routed or loose wire harnesses can interfere with other internal components and can become damaged or broken. Frayed or pinched harness wires can be difficult to locate. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides.

General cautions during removal and replacement

WARNING!Turn the product off, wait 5 seconds, and then remove the power cord before attempting to service the product. If this warning is not followed, severe injury can result, as well as damage to the product. The power must be on for certain functional checks during problem solving. However, the power supply should be disconnected during parts removal. The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts. CAUTION:Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do not straighten folds in the FFCs. You must make sure that all FFCs are fully seated in their connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA. Avoid pulling directly on wires to disconnect wire-harness connectors. Pull on the plastic body of a connector if possible to avoid damaging the connector wires. NOTE:To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a screw hole becomes stripped, repair the screw hole or replace the affected assembly.

Electrostatic discharge

CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when removing product parts. 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. 38Chapter 5 Removal and replacementENWW Page 61

Required tools

#2 Phillips screwdriver with a magnetic tip and a 152 mm (6.0 inch) shaft length ● Short #2 Phillips screwdriver with a magnetic tip and a 76 mm (3.0 inch) shaft length ● Small flat-blade screwdriver ● Needle-nose pliers ● ESD mat (if available; see the preceding ESD caution) ● Penlight (optional) ● CAUTION:Always use a Phillips screwdriver (callout 1). Do not use a pozidrive screwdriver (callout 2) or any motorized screwdriver. These can damage screws or screw threads. Figure 5-1 Phillips and pozidrive screwdriver comparison

Cleaning supplies

The scanner glass and ADF must be cleaned with appropriate supplies. When cleaning the scanner glass, see When cleaning the ADF, see

Screws and fasteners

Make sure that components are replaced with the correct screw type. Using the incorrect screw (for example, substituting a long screw for the correct shorter screw) can cause damage to the product or interfere with product operation. Do not intermix screws that are removed from one component with the screws that are removed from another component. For a complete list of screws and fasteners, see
