MX-CFX1

[1] PRODUCT OUTLINE

This inserter is an optional unit for the MX-5500N/MX-6200N/MX7000N series of digital complex machines. With the inserter installed, blank sheets or printed sheets can be inserted as covers (made of cardboard) or tabbed sheets without being subject to the printing process (and without passing through a fixing unit). When the inserter is combined with a finisher (optional) and a punch unit (optional), printed sheets can proceed to the hole punching or stapling process without being subject to the copying process (or without passing through the main unit).

B. Error detection

(1) EEPROM errors

Explanation:

1) Timeout error

The EEPROM is being programmed even after a predetermined time period (150 msec) has passed.

2) Writing error

The written data does not match the read data even when writing and reading are retried.

3) Reading error

Checking pieces of data read from three sources results in mismatch even when checking is retried.

(2) Reverse sensor adjustment error

Explanation:

1) When the DA output exceeds the upper limit

Even when the DA output is increased, the AD input value does not fall within the appropriated range.

2) When the DA output is less than the lower limit

Even when the DA output is decreased, the AD input value does not fall within the appropriated range.

A paper jam is detected if the reverse sensor is not turned OFF, which means presence of a sheet, even when the reverse motor has been driven for a predetermined amount after the reverse sensor is turned ON, which means presence of a sheet.

C. Alarm detection

Explanation:

An alarm is issued because the size of a sheet in the tray cannot be correctly detected when both the sub tray pullout detection sensor and the sub tray retraction detection sensor are turned OFF.

Indication:

Shown by a LED on the operator panel of the inserter or of the main unit as an inserter alarm.

4) Flapper Solenoid and Registration Clutch Drive Circuit (F_SOL and R_CL)

This circuit controls the flapper solenoid operation and the registration clutch engagement.

When the signal F_SOL is "H", Q2 turns on to activate the solenoid. Similarly, when the signal R_CL is "H", Q3 turns on to engage the clutch.

After the power is turned on, normally IC3-Pin8 (*RES) is "H". However, when the +5V voltage falls to 4.2V or less because of the power turned off or any trouble, IC3-Pin8 turns "L" to reset the CPU.

The clock signal from the CPU is transmitted to IC3-Pin3 (CK) at a regular interval to clear the watchdog timer embedded in IC3. How-

The flapper solenoid drive signal is the PWM signal. At the beginning of the solenoid activation, the signal is adjusted to set the solenoid at 100% duty cycle. After the plunger of the solenoid is pulled in, the signal is adjusted to set the solenoid at 70% duty cycle in

ever, if the clock signal from the CPU disappears because of a system trouble, IC3-Pin8 turns "L" to reset the CPU and stop the system operation.

The circuit transmits a reset signal to the CPU when the power is turned on or a power brownout is detected.

The circuit includes a watchdog timer intended to the CPU system operation diagnosis.

This circuit consists of the data storage EEPROM and the peripheral circuits.

IC4 is a storage memory for the adjustment settings of the reverse sensor (reflective sensor) and the paper width detection potentiometer, and passes the data to the CPU through the four-wire serial interface.

Once data is stored, the data is retained and not cleared even if the power is turned off.

IC4-Pin1 (CS) is the chip selection terminal, and stays "H" during passing data.

IC4-Pin2 (SK) is the serial clock terminal. The serial data is transmitted synchronizing with the clock signal input to the terminal

7) Inrush Current Limiting Circuit

IC4-Pin3 (DI) is the serial data input terminal. IC4-Pin4 (DO) is the serial data output terminal.

system to a certain value or less. The circuit consists of the PTC thermistor (PTH2) that limits a current and the FET (Q11) that allows a steady current flowing.

When the JAM cover open/closed detection switch is closed, the cathode voltage of ZD1 starts rising to the zener voltage according to the time constant of R55 and C46. During the rise of the cathode voltage, Q11 is off because no base current to Q10 keeps Q10 off, and then a current flows to PTH2 to charge the regeneration capacitor.

8) Operator Panel Drive Circuit

Operator P anel

After the regeneration capacitor is fully charged, and the cathode voltage of ZD1 reaches over the zener voltage according to the time constant of R55 and C46, Q11 is turned on because the base current from ZD1 to Q10 turns Q10 on. And then the current flows to Q11 instead of PTH2 to release the current limitation. The circuit consisting of PTH1 and D3 is intended to eliminate the electric charge accumulated in C46 immediately to limit an inrush current generated by momentary opening and shutting of the cover.

This circuit includes the input circuits of the switches on the operator panel and the drive circuits of the LEDs.

The circuits connected to CN15-Pin1, 2, 3 are the input circuits of the switches on the operator panel. The input signal from the switch goes "L" when the switch is on, "H" when off.

The circuits connected to CN15-Pin4,6-11 are the drive circuits of the LEDs on the operator panel. The LED lights when the signal is "H", does not light when "L".

This is the circuit of the operator panel board.

The operator panel drive board turns each of the LED1-6 on or off, and detects weather each of the PSW1-3 is on or off.

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 recommendable.

Solder composition code

(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 filer.
