Removal and replacement strategy
Cautions during removal and replacement
This chapter describes the removal and replacement of field-replaceable units (FRUs) only.
Replacing FRUs is generally the reverse of removal. Notes are included to provide directions for difficult
or critical replacement procedures.
HP does not support repairing individual subassemblies or troubleshooting to the PCA component level.
Never operate or service the product with the protective cover removed from the laser scanner
assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
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.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation.
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 self-tapping screw-hole
becomes stripped, repair the screw-hole or replace the affected assembly.
TIP: For clarity, some figures in this chapter show assemblies removed that are not required to be
removed to service the product (for example, the scanner and document feeder assemblies). The
procedures in this manual are correct for your product.
2 Chapter 1 Removal and replacement ENWW
Required tools
●#2 Phillips screwdriver with a magnetic tip and a 152-mm (6-in) shaft length
NOTE: For the best fit, use a JIS #2 Phillips screwdriver for the stapler/stacker.
●Small, flat-blade screwdriver
●Needle-nose pliers
●ESD strap (if one is available)
●Penlight
CAUTION: Always use a Phillips screwdriver (callout 1). Do not use a Pozidriv screwdriver
(callout 2) or any motorized screwdriver. These can damage screws or screw threads.
Figure 1-1 Screwdrivers
Types of screws
WARNING! 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 screw types and part numbers, see the Parts chapter.
Service approach
The HP LaserJet Enterprise 700 color MFP M775 uses a field repair strategy. Defective parts are
diagnosed and replaced at the Field Replaceable Unit (FRU) assembly level. Repair normally begins by
using the product internal diagnostics and the following two-step process:
1. Isolate the problem to the major system (for example, the network or server, or the product).
2. Troubleshoot the problem by using the procedures in the troubleshooting chapter.
After you locate a faulty part, the product can usually be repaired at the assembly level by replacing
FRUs. Some mechanical assemblies might need to be repaired at the subassembly level. Hewlett-
Packard Company does not support replacement of components on the printed circuit assembles.
ENWW Removal and replacement strategy 3
The user replaces toner cartridges as they are depleted. Additional instructions about other user-
replaceable parts are provided in this section.
The product tracks the amount of use on the customer-replaceable supplies by keeping a page count.
The product prompts the user to replace certain items when a supply is depleted or a specific number of
pages has been printed.
Swapping toner cartridges between products might cause a misrepresentation of supply life values and
is not recommended.
Before performing service
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 and damage to the
product can result.
The power must be on for certain functional checks during troubleshooting.
However, the power supply should be disconnected during parts removal.
1. Remove all paper.
2. Place the product on an ESD mat (if available). If an ESD workstation or mat is not available,
ground yourself by touching the sheet-metal chassis
before
touching an ESD-sensitive part.
3. Remove the toner cartridges.
4. Remove the toner collection unit (TCU)
5. Remove the trays.
After performing service
1. Reinstall the toner cartridges.
2. Reinstall the trays.
3. Return all paper to the trays.
4. Plug in the power cable and turn on the product.
5. Perform print-quality tests by printing from a host computer, the scanner glass, and the document
feeder.
Parts removal order
If multiple components must be removed to gain access to an assembly, the first step of the removal
procedure lists all of the components that must be removed to gain access to that assembly. Use these
lists to determine which parts must be removed before removing other parts.

Control-panel assembly
1. Tilt the control panel up.
Figure 1-2 Remove the control-panel assembly (1 of 4)
2. Remove the antistatic covers to reveal the thumbscrews.

Install the main drive assembly
NOTE: Installing a replacement assembly: follow the instructions in this section.
Reinstalling the original assembly: some of these instructions in this section do not apply (for
example, removing some the shipping tape). Do not rotate the gears when handling the assembly. If
the gears are rotated—and become out of phase—it will be difficult to install the assembly on the
product.
1. Do one of the following:
●Installing a replacement assembly: Do not remove the orange spacers and spacer-
shipping tape (callout 1) installed on the replacement main drive assembly. Remove the
remaining shipping tape (callout 2).
CAUTION: A gear (callout 3) on the back of the assembly is not captive when the shipping
tape is removed. Do not lose the gear when handling the assembly with the shipping tape
removed.
When removing tape, make sure that the entire strip is removed. Check the back of the
assembly to verify that the entire strip of tape is removed.
●Installing the original assembly: Do not remove the orange spacers (callout 1) installed
when the main drive assembly was removed.
CAUTION: A gear (callout 3) on the back of the assembly is not captive. Do not lose the
gear when handling the assembly.

How to use the parts lists and diagrams
The figures in this chapter show the major subassemblies in the product and their component parts. A
parts list table follows each exploded view assembly diagram. Each table lists the item number, the
associated part number, and the description of each part. If a part is not listed in the table, then it is not
a field replacement unit (FRU).
328 Chapter 2 Parts and diagrams ENWW
CAUTION: Be sure to order the correct part. When looking for part numbers for electrical
components, pay careful attention to the voltage that is listed in the description column. Doing so will
ensure that the part number selected is for the correct model.
NOTE: In this manual, the abbreviation “PCA” stands for “printed circuit-board assembly.”
Components described as a PCA might consist of a single circuit board or a circuit board plus other
parts, such as cables and sensors.
