CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE

Print controller units are extensively tested before shipping, to ensure that all applicable safety standards are
met, in order to protect the customer and customer engineer (hereafter called the CE) from the risk of injury.
However, in daily use, any electrical equipment may be subject to parts wear and eventual failure. In order to
maintain safety and reliability, the CE must perform regular safety checks.
1. Power Supply
•
Check that mains voltage is as specified. Plug the power cord into the ded-
icated wall outlet with a capacity greater than the maximum power con-
sumption.
If excessive current flows in the wall outlet, fire may result.
•
If two or more power cords can be plugged into the wall outlet, the total
load must not exceed the rating of the wall outlet.
If excessive current flows in the wall outlet, fire may result.
•
Make sure the power cord is plugged in the wall outlet securely.
Contact problems may lead to increased resistance, overheating, and
the risk of fire.
•
Check whether the power cord is damaged. Check whether the sheath is
damaged.
If the power plug, cord, or sheath is damaged, replace with a new power
cord (with plugs on both ends) specified by Konica. Using the damaged
power cord may result in fire or electric shock.
•
Check whether the power cord is not stepped on or pinched by a table and
so on.
Overheating may occur there, leading to a risk of fire.
•
Do not bundle or tie the power cord.
Overheating may occur there, leading to a risk of fire.
•
Check whether dust is collected around the power plug and wall outlet.
Using the power plug and wall outlet without removing dust may result in
fire.
•
Do not insert the power plug into the wall outlet with a wet hand.
The risk of electric shock exists.
