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.

    MASTER FEED 29 January 1998 2.2 MASTER FEED 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.
  • Page 16 29 January 1998 MASTER FEED 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.

  • Page 18: Paper Feed

    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.

    PAPER FEED 29 January 1998 2.3.1 PAPER FEED ROLLER 35.5 36.5 mm C228D505.WMF 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.

  • Page 20: Paper Separation Plate

    29 January 1998 PAPER FEED 2.3.2 PAPER SEPARATION PLATE 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.

    PRINTING 29 January 1998 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.

    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.
