Warning:  Read the following before handling electronic parts.
Handling ESD-sensitive parts 
Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent 
damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as 
turning off power before removing logic cards:
•Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until you are ready to 
install the part into the MFP.
•Make the least-possible movements with your body to prevent an increase of static electricity from clothing 
fibers, carpets, and furniture.
•Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This discharges 
any static electricity in your body to the MFP.
•Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If you are removing 
a pluggable module, use the correct tool.
•Do not place the ESD-sensitive part on the MFP cover or on a metal table; if you need to put down the 
ESD-sensitive part for any reason, first put it into its special bag.
•Machine covers and metal tables are electrical grounds. They increase the risk of damage, because they 
make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be 
discharge paths without being grounded.)
•Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install machine covers 
when you are not working on the machine, and do not put unprotected ESD-sensitive parts on a table.
•If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case).
•Be extra careful in working with ESD-sensitive parts when cold-weather heating is used because low 
humidity increases static electricity.
Model information used in the parts catalog.
If the printhead, controller board, or cables are being replaced, check the serial number label on the rear of the 
machine for the serial number and machine type/model number. Match the serial number  on the label up to the 
serial number range referenced in the parts catalog for the part being replaced. Also match the machine type/
model with the machine type model that is referenced in the parts catalog for the part being replaced. There is 
also a label inside the front door of the machine.,
Note:  When replacing the controller, printhead, power supplies, and cables, make a note of the printer serial 
number before ordering the replacement parts. Machines with a serial number greater than serial number 
5920000 use different part numbers for the parts mentioned above. Machine type
