Removal and replacement strategy Considerations 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 repairing individual subassemblies or troubleshooting to the PCA component level. WARNING! 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. WARNING! parts.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal
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 cables 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 M880 scanner and document feeder assemblies). The procedures in this manual are correct for your product.

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 assemblies 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 assembly with the screws that are removed from another assembly. For a complete list of screw types and part numbers, see the Parts chapter in the product repair manual.
Service approach The products described in this manual use 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 manual.
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. HewlettPackard Company does not replacement of components on the printed circuit assembles. The replaces toner cartridges as they are depleted. Additional instructions about other 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 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 imaging drums.
5.
Remove the trays.
After performing service 1.
Reinstall the toner cartridges.
2.
Reinstall the trays.
3.
Reinstall the imaging drums.
4.
Return all paper to the trays.
5.
Plug in the power cable and turn on the product.
6.
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.
ed paper sizes and types If the product is experiencing assembly failure, use the tables in this section to that the customer is using media that meets HP specifications.

Reinstall the punch hole assembly IMPORTANT: If you are installing a replacement punch hole assembly or punch controller PCA, you must set the punch hole assembly type and adjust sensor values on the punch controller PCA. See Replace the punch hole assembly or the punch controller PCA assembly on page 702. Adjust the punch hole location Punch adjustment is required when the punch holes are misaligned. If necessary, use the procedure below to adjust the position of punched holes after reinstalling, or replacing, the punch hole assembly. Adjust the screw on the puncher assembly to correct the position of punch holes. NOTE: The rear side punch hole is in a fixed position. The adjustment is made by pivoting the middle and front side hole in relation to the fixed rear side hole until all of the holes are aligned. 1.
Identify in which direction the punched hole adjustment is required. The figure below shows the punched hole misaligned to the left. Figure 1-1052 Determine the punch hole skew

To adjust the skewed hole alignment, do the following. NOTE: This adjustment procedure only moves the front portion of the punch to move the front hole into alignment with the rear hole. a.

After adjustment is completed, print 25 test pages and make sure that the punched hole alignment remains constant. NOTE: If some pages have skewed holes while others do not, the problem is a skew in the paper and not the punch.

Replace the punch hole assembly or the punch controller PCA assembly The punch controller PCA assembly stores configuration information for the punch hole assembly. Every time the punch hole assembly or the punch controller PCA assembly is replaced, the following procedures must be performed to set the punch hole assembly type as well as adjust sensors in the assembly. Set the punch hole assembly type Two types of punch hole assemblies are available: the 2/3 punch hole assembly (part number A2W94-67901), or the 2/4 punch hole assembly (part number CZ999-67902). Refer to the part number on the replacement part to determine the type of assembly you are installing. Follow these steps to set the punch hole assembly type. 1.
Turn the product power off.
2.
Locate the switches and LEDs on the punch controller PCA. ●
SW601 (callout 1) NOTE: SW601 has four electronic switches that can be configure in the ON or OFF position. The punch controller PCA is marked ON and OFF to show the current switch position.
