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 printer 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.
øCAUTION
The RAM has a lithium battery which can explode if handled incorrectly.
Replace only with the same type of RAM. Do not recharge or burn this
battery. Used RAM's must be handled in accordance with local regulations.
øATTENTION
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.

2
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 environmentally safe
manner and in accordance with local regulations.
3. When keeping used lithium batteries (from the main processing units) in order
to dispose of them later, do not store more than 100 batteries (from the main
processing units) per sealed box. Storing larger numbers or not sealing them
apart may lead to chemical reactions and heat build-up.

1. OVERALL INFORMATION
1.1 ESSENTIAL DIFFERENCES BETWEEN C232 AND
C229 MODELS
No. Item Remarks
1Thermal Head, Thermal
Head Power Supply, MPU,
I/O Board, PSU
Some related parts are also changed.
2 Paper Table Paper table capacity is changed from 1,000
sheets (C229) to 500 sheets (C232).
3 Paper Tray Two drawer-type paper trays are added.
The maximum capacity of the paper tray unit is
2,500 sheets.
4 Paper Delivery Table The side and end plates are automatically
adjusted to the print paper size.
5 Energy Saving
(New Function) Energy saving modes cut down the energy consumption below 10 W.
Only the LED at the clear mode key stays on.
Other keys and the LCD remain standing by until
the clear mode key is touched.
6 Drum Home Position
Indicator New LEDs are added to indicate when the drum is
at home position.
Green LED: Indicates the drum is at home
position.
Red LED: Indicates that drum is not at home
position.
7 JS Sorter Connection The new JS 40 sorter can be connected.
8 Friction Pad
(Paper Table) A newly designed friction pad is used.
9 New SP modes New SP modes are added for the paper tray and
JS 40 sorter.
10 Tray Feed Start Sensor A new sensor is added to detect paper fed from
the paper trays.
11 Torque Limiter The torque limiter is added to prevent damage to
the main motor when torque from the drum or
pressure cylinder gets too high and may lock it.
12 Paper Feed Length
Adjustment The paper feed length adjustment is changed. Refer to the PAPER FEED LENGTH
ADJUSTMENT in the replacement and
adjustment section.
13 Firmware Update Method The firmware on the MPU can be upgraded using
a flash memory card.
It is not necessary to use the card interface board.
Refer to LOAD PROGRAM (SP8-20) in the
service tables section.
