2. Z-FOLDING UNIT PAPER PATH

A. PAPER PATH WITH NO FOLDING

The feed rollers [1] feed the paper from the main machine into the Z-folding unit.

If Z-folding was not used for the job, the sheet feeds above the closed junction gate [2].

The upper exit sensor [3] detects the leading and trailing edge of the unfolded sheet.

The upper exit rollers [4] feed the unfolded sheet out of the Z-folding unit and into the finisher.

B. PAPER PATH WITH Z-FOLDING

The feed rollers [1] feed the paper from the main machine into the Z-folding unit.

The junction gate solenoid energizes and opens the junction gate [2]. The junction gate sends the sheet down into the Z-folding paper path.

The upper and lower stopper motors move the upper stopper [3] and lower stopper [4] to the positions for the paper size that was used for the job.

The feed sensor [5] detects the leading edge and trailing edge of the sheet. The pinch idle roller solenoid (upper) pulls the pinch idle roller [6] away from the pinch feed roller [7] and the paper can fall between the pinch rollers.

The anti-static brush [8] removes static electricity from the sheet.

When the fold timing sensor [9] detects the trailing edge of the sheet, it energizes the pinch idle roller solenoid (lower). This pushes the pinch idle roller [6] against the opposite pinch feed roller [7].

The lower stopper [10] stops the sheet and buckles it slightly toward the nip [11] of the 1st and 2nd fold rollers.

The pinch feed roller [1] turns and feeds the sheet down against the lower stopper [2]

At the correct time, the fold roller motor switches on and turns the:

• 1st fold roller [3]

• 2nd fold roller [4]

• 3rd fold roller [5]

The sheet continues to buckle until it feeds into the nip [6] of the 1st and 2nd fold rollers. These two rollers fold the sheet.

The leading edge sensor [7] detects the leading edge of the sheet:

• When the leading edge goes by while the paper feeds down (to the lower stopper).

• When the leading edge goes by again while the paper feeds up into the nip of the 1st and 2nd fold rollers.

If the leading edge sensor does not detect the leading edge at the correct time, this sensor signals a jam.

At the correct time, the pinch idle roller [8] is pulled away from the pinch feed roller [9] by the pinch idle roller solenoid (upper).

[10]

[2]

The 1st fold roller [1] and 2nd fold roller [2] continue to turn. This feeds the edge of the 1st fold up until it hits the upper stopper [3].

The sheet lifts the feeler of the upper stopper path sensor [4]. This sensor:

• Detects when the sheet comes to the upper stopper path.

• Detects when the sheet goes out of the upper stopper path.

The upper stopper sensor detects a jam if it does not detect that the sheet comes and goes at the correct times.

When the sheet feeds between the 1st and 2nd fold rollers, this pushes the first fold against the upper stopper. The sheet buckles down into the gap between the 2nd fold roller [5] and 3rd fold roller [6]. The second fold is made when the sheet feeds between the 2nd and 3rd feed rollers.

The 2nd and 3rd fold rollers [1] continue to turn and feed the sheet

down.

The feeler of the upper stopper path sensor [2] falls and the sensor detects that the sheet is gone. The fold rollers feed the folded sheet to the lower exit rollers [3].

The lower exit sensor [4] detects the leading edge and trailing edge of the sheet. If the trailing edge is not detected during the correct time interval, the sensor detects a jam.

The grip rollers [5] feed the folded sheet to the four pairs of vertical feed rollers [6].

The upper exit sensor [7] detects the leading edge and trailing edge of each folded sheet. If the leading and trailing edge are not detected during the correct time interval, this sensor detects a jam.

The upper exit rollers [8] feed the folded sheet into the finisher.

At the correct time:

• The upper stopper motor lifts the upper stopper [9] until the upper stopper sensor [10] detects that the upper stopper is at its home position. This stops the motor.

• The lower stopper motor lowers the lower stopper [11] until the lower stopper sensor [12] detects that the lower stopper is at its home position. This stops the motor.

Mounted below the upper stopper. 1) When the feeler of the upper stopper path sensor detects the paper when the crease of the first fold stops at the upper stopper, it delays long enough so the 1st/2nd feed rollers can continue to rotate and buckle the trailing edge of the paper below at the nip of the 2nd/3rd feed rollers, then the sensor switches off the 1st/ 2nd feed rollers and switches on the 2nd/3rd feed roller pair. The 2nd/3rd feed rollers pull the buckle into the nip and create the 2nd crease. 2) Detects the paper when it leaves the upper stopper path and signals an error if the paper does not leave at the prescribed time.

Junction Gate Solenoid

Pinch Idle Roller Solenoid (Lower)

Pinch Idle Roller Solenoid (Upper)

Opens and closes the junction gate solenoid. When not energized, the junction gate remains closed and paper passes over the back of the closed junction gate and through the Z-folding unit. When energized it opens the junction gate which guides paper down and into the paper path of the Z-folding unit. Attached to the pinch idle roller, this solenoid pushes the pinch idle roller and closes the gap between the pinch idle/pinch feed rollers when the fold timing sensor at the above the pinch idle roller detects the trailing edge of the sheet so the rollers can pinch and stop the paper in the paper path.

Attached to the pinch idle roller, this solenoid pulls the pinch idle roller away from the pinch feed roller when the feed sensor at the top of the Z-fold paper path detects the leading edge of the sheet so the paper can drop between these opposing rollers.

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.

Example:

(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.

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 file.
