Introduction
CMS:
The CMS (Customer Maintenance Support) is a system that supports the customer who conducts
a parts replacement operation by himself without getting an technical assistance from the customer engineer, to minimize the downtime (shutdown period of the machine operation) of the
machine of the customer.
Notices to the customer who employs the CMS:
When you want to employ the CMS, be sure to follow the instructions given by the customer engineer.
And also, when you conduct a part replacement operation, be sure to read each replacement
instruction and follow the specific instructions given in it.
For your safety while in the replacement operation, be sure to keep this CMS Instructions for
Replacement safely, and also be careful not to get it lost.
Should it get lost, contact our service representative.

Operations before replacing any part:
CAUTION
When conducting a part replacement operation, be sure to get guid-
ance from the customer engineer. And also, read the CMS Replace-
ment Instructions carefully before conducting a part replacement
operation by following the prescribed procedure and using tools also
prescribed. Be sure not to conduct any operations other than those
described in the CMS Replacement Instructions. When the pre-
scribed procedure and tools are not employed, this may cause
damage to the copier or you may get injured.
Before starting operations, be sure to unplug the power cords of the
copier main body and the optional equipment from the power outlet.
When the power cord is plugged into the power outlet, some electri-
cal components may be energized even if the power switch is
turned off. So, be careful not to get an electric shock.
The temperature gets high in the vicinity of the fusing unit. Be careful
not to come into contact with it, or you may get burned.
CMS part replacement operation:
WARNING
Do not allow any metal parts such as clips, staples and screws to fall
into the inside or opening of the copier.
They may cause a short circuit to the internal parts of the copier,
thus leading up to a risk of an electric shock or fire.
Check the wiring harness for squeezing and any other damage.
Current may leak, thus leading up to a risk of an electric shock or
fire.

For your safe operation (continued)
Power plug:
WARNING
• Be sure to avoid plugging or unplugging the power cord with a
wet hand. You may get an electric shock.
• Be sure to plug the power cord securely into the power outlet.
Otherwise, a fire may result, or you may get an electric shock.
CAUTION
• When unplugging the power cord from the power outlet, be care-
ful not to pull the power cord. Otherwise, a fire may result with the
power cord damaged, or you may get an electric shock.
When any abnormal condition is found:
WARNING
• When the copier gets hot abnormally, or when it gives out smoke,
a foul smell or abnormal noise, turn off the power switch at once.
And then be sure to unplug the power cord from the power outlet
and contact our service technician.
• When the copier is let fall or when the cover is damaged, turn off
the power switch at once. And then, be sure to unplug the power
cord from the power outlet and contact our service technician.
Using the copier as it is may lead up to a fire, or you may get an
electric shock.
CAUTION
• Some internal parts of the copier develops a high temperature,
and you may get a burn when you come into contact with one of
these parts. When checking the internal parts while in a part
replacement operation, be careful not come into contact with a
section like these (around the fusing unit) with a symbol indicating
"High Temperature" provided.

NOTE
• The method for replacing the pick-up roller assembly/separation roller assembly is the same for

• After completion of the installation, rotate the pick-up roller in the direction of the paper feed
(counterclockwise as seen from the front) to check to see if the paper feed roller, the belt and the
coupling section rotate smoothly. The rotation of the pick-up roller is restricted only to the direc-
tion of the paper feed (counterclockwise as seen from the front) and be absolutely sure not to turn
it clockwise.
• Be sure to take note that the direction of the pick-up roller assembly is different for the main body
and the PF-701.

NOTE
• The removing/reinstalling methods of the pick-up roller unit and the separation roller unit are the
same for all of the trays /3, /4 and /5. The explanation here is made of the examples of the tray /3.
• After completion of installation, be sure to rotate the pick-up roller in the paper feed direction
(clockwise as seen from the front side) to check to see if the paper feed roller and the belt rotate
smoothly. The rotation is restricted only to the paper feed direction (clockwise as seen from the
front side) and be careful not to rotate it counterclockwise.
• Be careful that the pick-up roller unit and the separation roller unit are different in the direction for
the main body and the PF-701.

• For a separation roller unit, there are two
types and their use is decided according to
the type of trays. The type (1) is used for the
trays /3 and /5 and the type (2) that has more
gears is used for the tray /4.
