IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals, make
sure that the power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. If any adjustment or operation check has to be made with exterior covers off or
open while the main switch is turned on, keep hands away from electrified or
mechanically driven components.
HEALTH SAFETY CONDITIONS
1. If you get ink in your eyes by accident, try to remove it with eye drops or flush
with water as first aid. If unsuccessful, get medical attention.
2. If you ingest ink by accident, induce vomiting by sticking a finger down your
throat or by giving soapy or strong salty water to drink.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The printer and its peripherals must be installed and maintained by a customer
service representative who has completed the training course on those
models.
CAUTION
The RAM board has a lithium battery which can explode if handled
incorrectly. Replace only with the same type of RAM board. Do not
recharge or burn this battery. Used RAM boards must be handled in
accordance with local regulations.
ATTENTION
La carte RAM comporte une pile au lithium qui présente un risque
d'explosion en cas de mauvaise manipulation. Remplacer la pile
uniquement par une carte RAM identique. Ne pas recharger ni brûler cette
pile. Les cartes RAM usagées doivent être éliminées conformément aux
réglementations locales.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Dispose of replaced parts in accordance with local regulations.
2. Used ink and masters should be disposed of in an envionmentally safe manner
and in accordance with local regulations.
3. When keeping used lithium batteries (from the main control boards) in order to
dispose of them later, do not store more than 100 batteries (from the main
control boards) per sealed box. Storing larger numbers or not sealing them
apart may lead to chemical reactions and heat build-up.

2.2.1 MASTER FEED MECHANISMS
A 600 dpi thermal head and a new more heat-sensitive master is used to improve
the printing quality. The new master is thinner and has a smoother surface. The
following improvements are implemented to improve master feed.
1. Three master buffer fan motors [A] are used instead of the one fan motor used
in the C223. This generates stronger suction to guide the master into the
master box [B].
[B]
[A]
[D]
[E]
[C]
C228D502.WMF
2. To ensure correct master feed, the material of the upper master feed roller [C]
has been changed to an anti-static rubber. (A sponge-like material was used
for the C223.)
The new master feed roller [C] rotates slightly faster than the platen roller [D].
This stretches the master on the thermal head (under the platen roller) and
makes sure that the master is made accurately. A torque limiter built into the
upper master feed roller gear can release the master feed force to prevent the
master from being damaged in this area.
Also, the counter roller [E] has been added to prevent the master from
wrapping around the upper master feed roller.

C228D503.WMF
3. A metal master guide plate was used between the master feed roller and
reverse roller for the C223. This was good for grounding static electricity.
However, when static electricity is grounded, the master tends to stick to the
guide plate. As a thinner master is used for the C228, the guide plate [A] is
made of a plastic material. This prevents the master from being stuck on the
guide plate surface even if static electricity is generated. Also, ribs have been
added to the new guide plate to feed the master more smoothly.
4. Four strips of mylar [B] have been added to the surface of the master guide
plates. This can prevent the master from catching on the rollers under the
master feed and reverse rollers. Other strips of mylar are used in front of the
master feed roller [C] and after the platen roller [D].
NOTE:
These mylar strips must be carefully repositioned when the rollers are
reinstalled.

The thermal head [A] is pressed against the platen roller [B] only during the master

the position of the cam [C].
The cam position is changed by the thermal head pressure release motor [D] via
gears. The thermal head pressure release sensor [E] monitors the cam position.
The sensor, which is a photointerrupter, is interrupted by the shutter mounted on
the gear [F] as the pressure release motor turns to maintain the cam position.

29 January 1998 PAPER FEED
2.3 PAPER FEED
To improve paper feed, especially for thin paper, the paper feed roller and the
separation plate have been changed.
In addition, the shapes of the two paper feed cams (the cam profiles) have been
changed in order to make the paper registration more accurate.
With the new cams, the leading edge of the paper reaches the second feed roller
faster than before. Then, the second feed roller can start feeding the paper earlier.
Thanks to this, the second feed roller can start feeding the paper at a lower
transportation speed. (The time that the paper reaches the press roller position is
still the same, but the acceleration from the second feed roller has become more
moderate.) As a result, the paper registration has become more accurate.
Since the timing for the second feed roller to start feeding the paper was
advanced, the paper detection feeler used in the C223 could not be used. A
photocoupler is used instead. For more details about this, refer to the Printing
section.
NOTE:
1) Due to the new cams, the adjustment values for second feed roller
operation are changed. For details, refer to ‘Feed Length of the Second
Feed Roller Adjustment‘ and ‘Second Feed Roller Start Timing
Adjustment‘ in the ‘Replacement and Adjustment’ section. (The ‘Feed
Length of the Paper Feed Roller Adjustment’ procedure is still the
same.)
2) The new paper feed cams cannot be used on the older models since
those models use the paper detection feeler.

C228D505.WMF
[A]
In this model, the two rubber rollers [A] on the core roller are separated. This helps
to prevent creasing of paper that can be caused by the narrower roller assembly of
the C223. (This was likely with very thin paper.)
The material of the core roller [B] was changed from plastic to metal for better
stiffness. As a result, to balance the weight of the whole paper feed roller unit, the
number of balancing weight plates on the feed roller bracket was reduced from
three to two.
Since the weight of the paper feed roller itself has increased, the roller tends to
overrun (it keeps on feeding paper) after the roller driving force stops. To prevent
this, a spring [C] which works as a brake has been added at the end of the shaft.
NOTE:
When servicing, make sure that the core roller is between 35.5 mm and
36.5 mm from the end of the shaft.

2.3.2 PAPER SEPARATION PLATE
[D]
[C]

[B]
C228D506.WMF
If the leading edge of paper stacked on the paper table curls downwards, it tends
to be caught by the separation plate and this causes a jam. The shape of the
separation plate [A] has been changed (see the diagram) to improve paper feed in
such a case.
For the same purpose, the shape of the upper edge of the entrance plate [B]
(which holds the separation plate) has been changed as shown.
The rubber part of the separation plate [C] has been lengthened to improve paper
feed, especially for thick paper. The lengthened rubber can guide the paper
leading edge to the upper separation roller [D] surface more precisely. Because of
this, the paper edge hits the upper separation roller more gently. This prevents the
paper leading edge from being damaged at the area where the separation plate
(the rubber part) contacts the upper separation roller surface. (This was likely with
thick paper.)

2.4 PRINTING
2.4.1 OVERVIEW
Printing Pressure Cam
For better printing quality, the shape of the printing pressure cam (the cam profile)
has been changed.
The new cam applies printing pressure to the drum faster than before. The press
roller is pressed against the ink roller (the master and the drum screens are in
between) before the leading edge of the paper reaches this section.
In the C223, the press roller is pressed against the ink roller just when the paper
leading edge reaches this point. In this case, the paper leading edge is strongly
pressed against the master surface on the drum. Since the new master is thinner
and delicate, the paper leading edge tends to damage the master surface if the
same printing pressure cam is used, especially during a long printing run. (If the
master surface is damaged, ink will leak and transfer onto the paper.) The new
printing pressure cam can avoid this situation.
NOTE:
1) Because of the new printing pressure cam, the adjustment values
(angles) for printing pressure application timing and exit pawl operation
timing are changed. Refer to ‘Pressure Timing Adjustment’ and ‘Exit
Pawl Timing Adjustment’ in the ‘Replacement and Adjustment’ section.
2) The new printing pressure cam cannot be used in the older models.
Because of the new cam profile, the shift range in the backward
direction in image shifting mode has been changed from 15 mm to 10
mm. (In the forward direction, it is 20 mm as before.)
Paper Detection and Printing
In the C223, the paper detection feeler was used in order to prevent the press
roller from contacting the drum (without paper) and getting ink on it when a paper
misfeed occurred before the paper reached the press roller.
The paper detection feeler could be pressed downwards by paper since a gap
between the paper detection arm and the pressure on/off lever was created when
the widest part of the pressure cam reached the bearing on the pressure on/off
lever. With the earlier second feed roller start timing, this gap cannot be created.
Therefore, the same mechanism is not used. (The timing was changed to make
paper registration more accurate; see the Paper Feed section for details.)
NOTE:
Instead of the paper detection feeler, the registration sensor (a photocoupler) is
used. When the sensor detects the paper, the printing pressure solenoid energizes
to start applying the printing pressure. (In the C223, the printing pressure solenoid
was energized as soon as paper feed started.) The sensor is also used as a paper
jam detector.
For the details of the paper detection feeler operation, refer to the C223
Service Manual. (Section 5.2, ‘Paper Detection And Printing Pressure
On/Off Mechanism’ in the ‘Detailed Section Descriptions’ section.)
2-8
Page 22
29 January 1998 PRINTING
For more details about this mechanism, refer to the following ‘Paper Detection and
Printing Pressure On/Off Mechanism’ section.
Quality Start
The detection arm release solenoid which was used in the C223 has been
removed. Since the paper detection feeler has been removed, the detection arm
release solenoid is not necessary to start the drum stroke operation in the quality
start mode.
When the drum stroke operation starts, the printing pressure solenoid turns on.
This disengages the pressure on/off lever and starts applying the printing
pressure.

C228D507.WMF
When the paper is detected by the paper registration sensor [A], the printing
pressure solenoid [B] is energized. The stopper arm [C] then disengages the
pressure on/off lever [D]. The pressure on/off lever, which is connected to the end
of the press roller arm [E], starts moving when the printing pressure cam [F] starts
moving; the cam moves bearing [G], which is on the lever. The press roller is
pressed against the ink roller.
The printing pressure solenoid is de-energized when the printing pressure sensor
is activated; this is soon after it is energized. The stopper arm [C] returns and is
pressed against the pressure on/off lever, due to tension from a spring. (The
stopper arm just rides on the edge of the pressure on/off lever at this time.) To
finish applying the printing pressure, the bearing [G] on the pressure on/off lever is
pushed by the printing pressure cam and the lever turns clockwise, until it is
engaged by the stopper arm.
If the next sheet of paper is detected by the registration sensor within a certain
period, the printing pressure solenoid is again energized to disengage the pressure
on/off lever. The printing pressure for the next sheet of paper starts being applied.
If the registration sensor is not activated, the machine detects a paper misfeed
condition (Location B Misfeed). In this case, the printing pressure solenoid stays
de-energized and the printing pressure is not applied. This can prevent the press
roller contacting the drum (without paper) and getting ink on it because of the
paper misfeed.
NOTE:
In the C223, Location B Misfeed was detected when the printing pressure
sensor was not activated within a certain period.

Descriptions
The light reflected from the original goes to the CCD, which converts the light
signal into an analog electrical signal. The analog signal is sent to the A/D
conversion PCB, where it is changed to 6-bit digital data. The 6-bit data is changed
to 1-bit data in the image processing PCB and it goes to the thermal head. The
thermal head drive circuit is built into the image processing PCB.
The 6-bit to 1-bit conversion procedure depends on the image settings on the
operation panel.

4) SP Mode No. 87 — Memory Print
Normally, in platen mode (when no originals are placed in the ADF), the machine
stops when the 1st print job is finished even if the tape marker is installed, so that
the next original can be placed. The next printing job starts when the Print Start
key is pressed.
If "1" is selected in this mode, after the 1st print job is finished, the tape marker
feeds a strip of tape and the next print job starts immediately afterwards.
5) SP Mode No. 88 — Auto Memory/ Class
In Memory/Class mode, the machine normally stops when the first print job is
finished if the tape marker is not installed.
If "1" is selected in this mode, the machine stops for a while (this interval is the
same as when the tape marker is operating). Then it continues with the next print
(or master making) job.
6) SP Mode 92 — Thermal Paper Mode
You can use this mode to test the thermal head.
Place some thermal printer in the plotter face down and change this SP Mode to 1.
Place an original on the exposure glass and press the Master Making key. The
machine starts printing on the thermal paper without doing the master clamp
process.
You can also enable SP Mode 90 and press the Master Making key to test the
thermal head without placing an original on the exposure glass.
7) SP Mode 93 — Erase Area Check
This checks the erased area for shadow erase (Center and Edge Margin Erasing).
If you make a master and print an image with this mode, the machine makes a
background pattern on the area to be erased.

C228R500.WMF
Purpose:
Adjustment Standard:
There are two steps.
1) The output voltage for the thermal head from the power supply unit must be
22.5 volts (r 0.5).
2) The output from the DC/DC converter board is different from one thermal
head to another. Refer to the voltage value (X) on the thermal head decal.
The output should be between "X-0.1" and "X" volts.
NOTE:
1. Turn off the main switch and remove the paper exit cover plate (4 screws).
2. Disconnect connector CN503 of the power supply unit.
3. Turn on the main switch, and access the SP mode and select output check
mode (SP131) No. 41.
4. Press the Print Start key to apply thermal head voltage continuously (60
seconds).
To maintain the quality of masters and to extend the life
of the thermal head.
This adjustment is always required when the thermal head or power supply
unit is replaced.
