Repair Information

This chapter explains how to make adjustments to the printer and 
how to remove defective parts.

Note:  Read the following before handling electronic 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 boards:

Keep the ESD-sensitive part in its original shipping container (a special 
“ESD bag”) until you are ready to install the part into the machine.

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 machine.

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 machine 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.
