* Paper feed section roller life
The life of roller used in paper feed section of each option is
different. (See the table below.) When a certain paper feed unit
is used greater than usual, its life may be expired before the
maintenance timing.
Actually, however, different sizes of paper are used with different paper feed trays, and it is quite rare that the roller replacement must be made before the maintenance timing.
IF a certain paper size is used more than normal, set feed
trays for that paper size and explain the frequency of maintenance to the client.
When servicing, check the use frequency of each paper feed
tray, and replace the rollers as needed.
When cleaning the roller, it is advisable to use a wet cloth with
a small quantity of water.
The amount of friction applied to the rollers increases from pick
up to paper feed to paper separation.

When paper is placed on the tray, the 1st paper set sensor in the
tray actuates and switches on the 1st tray lift motor. The pick-up
roller unit drops and the top of the stack in the tray pushes up the
pick-up roller unit until its actuator actuates the 1st bottom plate
position sensor [A] and switches the motor 1st tray lift motor off.
The 1st pick-up roller HP sensor [B] controls the operation of the
1st pick-up motor [C]. The 1st pick-up motor is off when the actuator is up and there is no paper in the tray. This is the pick-up roller
home position. When the actuator de-actuates the sensor after the
tray lifts, this switches on the 1st pick-up roller motor. At the end of
the job, the actuator descends with the bottom plate and switches
the motor off.
The pick-up roller [D] picks up the sheet, and the feed belt [E] feeds
the sheet to the paper feed roller [F]. The separation roller [G]
reverses if more than one sheet is fed.
This is a standard FFR device
The paper feed sensor [H] detects the timing of the feed and signals a jam if the paper does not arrive or if the paper stops.
As sheets feed from the top of the stack:
• The pick-up roller unit descends until the actuator on the pick-up
roller unit drops out of the 1st bottom plate position sensor [A].
This activates the 1st tray lift motor.
MX-CFX2 DETAILS 4 – 1
• The 1st tray lift motor switches on to raise the stack until the
actuator enters the pick-up roller unit position sensor again and
switches the lift motor off.
• This cycle repeats until the end of the job or until paper runs out.

When feed starts with a full tray, the actuator [A] on the rotating
shaft of the bottom plate lift arm [B] is at the 1st tray lower limit sensor [C].
As paper feeds and the stack grows smaller, the lift arm rises and
the actuator descends until the actuator reaches the 1st tray upper
limit sensor [D]. At this time the operation panel signals near-end
for the 1st tray.
When the last sheet feeds, the paper feed sensor, a photosensor
(not shown) signals that paper has run out.

The side fences (1) and (2) can be adjusted to standard and nonstandard paper sizes.
When the side fences are moved to match the paper width, a feeler
[A] slides along the wiring patterns on the paper width switch terminal plate [B].
The combination of the following two factors determines the paper
size:
• The position where the feeler activates the terminal
• The status of the paper length sensor [C] (ON or OFF).
The paper end sensor [D] de-activates when the last sheet is fed
and reports that the paper tray is empty.
The paper size is detected by six sensors whose combined readings are used to detect the following paper sizes.

LEAD-FREE SOLDER
The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.
The alphabet following the LF mark shows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread.
Never use conventional lead solder thread, which may cause a breakdown or an accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommended.

(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after completion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine file.
