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, in addition to damage to the
product. The power must be on for certain functional checks during troubleshooting. However, disconnect
the power supply during parts removal.
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 might 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 pre-folds in the FFCs. You must fully seat all FFCs in their connectors. Failure to fully seat an FFC
into a connector can cause a short circuit in a PCA.
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 photos in this chapter show components removed that would not be removed to
service the product. If necessary, remove the components listed at the beginning of a procedure before
proceeding to service the product.
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, or use an ESD
strap. If an ESD workstation, mat, or strap 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.
Required tools
●
#2 Phillips screwdriver with a magnetic tip and a 152-mm (6-inch) shaft length
●
Small flat-blade screwdriver
●
Needle-nose pliers
●
ESD mat or ESD strap (if one is available)
●
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.

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 by using the
screws that are removed from another component.
NOTE: The screw illustrations in the following table are for reference only. Screws might vary in size and
appearance from those shown in this table.

Remove all paper from the product.
●
Turn off the power using the power switch.
●
Unplug the power cable and interface cable or cables.
●
Place the product on an ESD workstation or mat, or use an ESD strap (if one is available). If an ESD
workstation, mat, or strap is not available, ground yourself by touching the sheet-metal chassis
touching an ESD-sensitive part.
●
Remove the print cartridge.
After performing service
●
Plug in the power cable.
●
Reinstall the print cartridge.
●
Load paper in the product.
Post-service test
before
Perform the following test to verify that the repair or replacement was successful.
Print-quality test
1. Verify that you have completed the necessary reassembly steps.
2. Make sure that the tray contains clean, unmarked paper.
3. Attach the power cord and interface cable or interface cables, and then turn on the product.
4. Verify that the expected startup sounds occur.
5. Print a configuration page, and then verify that the expected printing sounds occur.
6. Print a demo page, and then verify that the print quality is as expected.
7. Send a print job from the host computer, and then verify that the output meets expectations.
8. Clean the outside of the product with a damp cloth.
Copy quality test
1. Verify that you have completed the necessary reassembly steps.
2. Perform steps 1-8 in test 1 to check basic print quality.
3. Place the configuration page in the document feeder.
4. Print a copy job, and then verify the results.
5. Clean the outside of the product by using a damp cloth.
