CONTENT

We are pleased to announce the availability of our newest finisher, the MJ-1014. The MJ-1014 is very
similar to the MJ-1006, expect for minor changes. No Service Manual has been specially prepared for
the new finisher/MJ1014 and this BSI, in which the differences from the MJ1006 are shown, is to serve
as a substitute. We explain the summary of the functions as follows. Refer to the attaching file for the
details.

C. Feeding and Delivering

CHAPTER 2 FINISHER UNIT BASIC OPERATION

1. Outline

: MJ-1006/1007 ONLY

The finisher mov es copies arriving from the copier to the normal tray , or the saddle stitcher unit
(Saddle Finisher MJ-1007) according to the mode of delivery. On the trays, the copies are subjected
to job offset or stapling as instructed by the copier.

The inlet motor (M7), the feed motor (M1), and the feed motor (M8) are the stepping motors,
and the delivery motor (M2) is a DC motor. These motors are controlled by the microprocessor
(CPU) on the finisher controller PCB, and rotate either clockwise or counterclockwise.

The paper paths are equipped with the following five sensors for detection of paper (arrival,
passage):

●

Inlet sensor (PI1)

●

Delivery sensor (PI3)

●

Stapling tray sensor (PI4)

●

Buffer path paper sensor (PI14)

In addition, each delivery tray is equipped with a sensor designed to detect the presence/ab­sence of paper on it.

●

No 1 tray paper sensor (PI11)

●

No. 2 tray paper sensor (PI12)

If a copy fails to reach or move past each sensor within a specific period of time, the finisher
controller PCB identifies the condition as a jam, and stops the ongoing operation and at the same
time informs the copier of the condition.

H. Detecting the Height of the Stack on the Tray

1. Outline

The number of sheets delivered to the tray and the number of sets (stapling or job of fset opera­tions) are stored in memory by the finisher controller PCB. The height of the stack is check ed by the
height sensor (PS1). See Table 2-202 for the maximum loading capacity of each tray.

The finisher controller PCB stops operation when the conditions in Table 2-202 occur, inform­ing the host copier that the tray is full.

Note: 1. The capacity for non-staple sort mode is approximate and computed based on 80 g/m2 paper.

2. Alignment for stacks consisting of 750 sheets or more is not guaranteed.

3. The accuracy of the stack height is ±7mm.

The sheet does not move past the buffer path paper sensor when an equivalent of twice the
feeding length of the sheet has been fed after the buffer pa th paper sensor turned on.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

III. POWER SUPPLY SYSTEM

1. Outline

The finisher controller PCB is supplied with 24 VDC power when the copier is turned on.
Some of the 24 VDC po wer is used to dri v e the motors and the solenoids etc., while the rest is used
for sensors and ICs on PCBs after being turned into 5 VDC by the w ork of the regulator IC (Q14) on
the finisher controller PCB. The 24 VDC po wer is also used to feed power from the f inisher control­ler PCB to the saddle stitcher controller PCB.

Some of the 24 VDC po wer used to dri ve motors is cut off when the door switch (MS1) is made
open. The power to the saddle stitcher controller PCB, however, will not be cut off.

Figure 2-301 is a block diagram showing the power supply system.

Figure 2-301

2. Protection Functions

The 24 VDC power channel used to drive motors and solenoids is equipped with a circuit
breaker (CB1) for protection against overcurrent. The 24 V channel used to drive the feed motor 1
(M1), feed motor 2 (M8), inlet pass motor (M7), alignment motor (M3), and stapler shift motor
(M4) is equipped with a fuse, which is designed to melt in the presence of overcurrent.

Caution:

Replace the lithium battery only with the one listed in the Parts Catalog. Use of different battery may
present a risk of fire or explosion. The battery may cause a fire or present chemical burn hazard if
mistreated. Do not recharge, disassemble, or dispose of it by fire.
Keep the battery out of reach of children and discard any used batteries promptly.
