INTRODUCTION
This manual explains only the features of the N850 (C224 model) that are
different compared with the VT2000 series (C211, C212 and C213 models).
So, please refer to the VT2000 series service manual for the sections which
are not described in this manual.
The N850 (C224 model) has been designed based on the N865 (C216
model), and some descriptions are the same as the N865 service manual.

ESSENTIAL DIFFERENCES BETWEEN C211/C212/C213
AND C224 MODELS
To ensure drum connection, a drum lock lever has been
added inside the front door. To remove the drum from the
machine, the drum release lever must be pulled up to
disconnect the drum connector. (Same as the C216
model.)
The location of the ink detection board has been changed
from the upper side to the right side of the drum shaft. The
ink type switch (SW901), which was not used (always set
at oil type), has been removed. (Same as the C216 model.)
To supply ink to the ink roller evenly, the second ink supply
hole (count from the front side) of the drum shaft is
covered with a strip of tape.
(Same as the C216 model.)
To ensure paper separation from the drum, the exit pawl
air pump system is standardized. (Same as the C216
model.) (The pump system can optionally be installed in
models of the C211 series.)
The main board and the image processing board have
been combined into one board.
The thermal head drive board has been removed. The
function of the board has been moved to the main board.
The thermal head voltage is directly applied from the
power supply unit. The main board applies the signal to the
PSU to supply thermal head voltage only during the master
making process. (Same as the C216 model.)
The paper table drive motor has been changed from an ac
motor to a dc motor.
The air knife motor has been changed from an ac motor to
a dc motor.
The pressure plate position switch and the full master
detecting switch have been eliminated.
Three photo-interrupters, upper and lower pressure plate
sensors and full master box sensor are used instead.

motor and pressure plate motor. Due to this modification,
the master box capacity has been increased.
A user can select from 2 to 9 rotations of the drum while
one sheet of paper is fed.
If "Economy mode" is selected on the operation panel, a
lower thermal head energy is applied when a master is
made. As a result, the image will be lighter than normal
and ink consumption will be less.
"Secret mode" can be selected by changing DIP SW103-6.
If this mode is selected, the Print key is disabled after
turning the main switch off and on. (Only the "Master
making key" is available.)

Descriptions
C224D500.img
A dc motor [A] installed in the rear of the machine drives the master eject
rollers [B] through a timing belt [C] and gears [D] to eject used masters. The
master is transported between the upper and lower master eject rollers to be
ejected to the master eject box.

[I]
[C]
[B]
[E]
C224D501.img
After the used master is transported to the master eject box, the master is
compressed by the pressure plate.
The pressure plate is driven by an independent dc motor. The pressure plate
motor [A] drive is transmitted to the gear [B] through gears, and the pin [C]
moves link [D] down until the lower pressure plate sensor [E] is actuated.
Spring [F] pulls down on the pressure plate [G] and the ejected master in the
master eject box is compressed. Then the pressure plate motor stays off until
the master making process is finished. Then the pressure plate motor starts
again to return the pressure plate to the upper position. The motor stops
when the upper pressure plate sensor [H] is actuated.
The machine detects that the master box is full if the full master box sensor [I]
is not actuated when the pressure plate goes down.

2.1 OVERALL
The CCD [A] which corresponds to a 300 dpi pixel density is used for the
C224 model.
Light reflected from the original goes to the CCD through a lens.
The CCD changes the light into an analog electrical signal which is changed
to 4-bit digital data in the A/D conversion PCB. The main control PCB
changes the 4-bit data into 1-bit data to drive the thermal head.

• Width 256 mm
• Number of thermal head elements 3072 dots
• Density of thermal head elements 300 dpi
(2) Thermal Head Control
The PSU applies thermal head voltage which is adjusted in the factory to
match individual thermal head characteristics. The main control PCB
controls the thermal head to reproduce the image on the master.

C224D503.wmf
The thermal head energy is controlled by changing the pulse width.
The pulse is controlled by the ENL signal from the main board corresponding
to ENLTRIG from the image processing board.
C224D504.wmf
Thermal head voltage is applied from the PSU only during the master making
process. This is controlled by the VHDON signal (CN105-14) from the main
board.

When the drum release lever [A] in front of the machine is raised, the
connector [B] is pushed away from the drum by the bracket [C] through the
link [D], and is thus disconnected. The connector moves only horizontally due
to the guidance of the shafts [E]. The bracket [C] also pushes the drum lock
lever [F] to release the drum lock allowing the drum to be removed.
While the drum is out of home position, the drum lock solenoid [G] is
energized and the stopper [H] locks the link [D] so that it will not be pulled.
The solenoid is de-energized when the drum stops at the home position
(when the 1st drum home position sensor is actuated).

4.4 THERMAL HEAD TEST
The purpose of this mode is to distinguish whether the cause of the image
problem is located before or after image processing.
Output image: The normal output of this test pattern image mode is one
of the dither matrix patterns as illustrated below.
Master processing length:
Main scan (Horizontal) direction: Full width of the thermal head
Sub-scan (Vertical) direction: Same as the vertical size of
the original set on the original

[Example] Problem: Vertical white lines appear on the print.
Possible Cause 1 If the same problem appears on the output
image from the thermal head in test pattern
image mode, the cause should be in area
B, as shown above.
Possible Cause 2 If the output image from the thermal head is
correct in test pattern mode but the output

NOTE: 1. The VT-M master can be installed in the C224 model, however, a
weak image (sometimes blank) will appear.
This is because the VT-ΙΙ-M master is more sensitive than the
VT-M master.
2. The modified master clamper (P/N C2074948) must be installed.
3. The drum can be installed. However, the maximum image area is
