Unpacking And Installing - Canon NP6251 Service Manual

CHAPTER 9 INSTALLATION
II. UNPACKING AND INSTALLING
When a piece of metal is brought in from a cold to a warm area, droplets of water
tend to form on its surface. This phenomenon is known as condensation, and the use of
a copier subjected to condensation can turn out blank copies.
If you are installing a machine just brought in from a cold place, keep it without
unpacking for at least one hour so that it becomes used to the room temperature.
Caution:
A. Keep the following in mind when delivering the machine to the user by way of
stairs:
1. Draw out the fixing/feeding unit, holding tray, and copy paper from the
machine, and deliver them separately. (If an RDF is installed, remove it also.)
2. To lift the body, do not use the grips on the pick-up/delivery assembly; rather,
keep the hands at four bottom corners of the machine.
B. If the environment has a relatively high humidity, image faults can occur,
requiring you to switch on the drum heater to prevent the problem.
If the reading of 'RHUM' (inside humidity) in service mode (*1*) is 60% or more,
turn on the drum heater (right of the switch pressed).
C. Shift up the two (front) adjusters on the bottom of the machine to check to make
sure that they are released.
Take care not to lose the adjusters. (They can be shaken out while the machine
is being moved.)
D. Be sure to work in a group of three. In particular, when removing the pads, one
person should be at the rear of the machine holding one grip and one at the front
holding one grip while one removes the pads and the base plate on each side.
E. Keep the following in mind when moving the machine:
1. The grip to be used in the side (Figure) is kept on the side of the machine.
2. Check to make sure it has been inserted fully before holding it and lifting the
machine. (It can slip out if not handled with care.)
3. The machine weighs about 210 kg. Be sure to work in a group of four when
lifting it.
