1.4 Marking
1.4.1 Warning Label
The warning labels are affixed to the sections which may cause bodily injury.
Follow the instructions on warning labels during maintenance.
1.4.2 Warning/ Caution Marking
The following low voltage power supply, high voltage power supply 1/ sensor board and sub high voltage
power supply board involve the risk of electric shock, and especially a caution marking is put on the low
voltage power supply.
CAUTION
Low voltage power supply High voltage power supply1 Sub high voltage power supply
/Sensor board
A heatsink and a core of transformer involve the risk of electric shock. Test before touching.
Even after fuse opening, the circuit involves the risk of electric shock.
Note: If removing the cover assy upper and turning power on, be careful not to touch
the low voltage power supply, high voltage power supply 1/ sensor
board and sub high voltage power supply board. There is a possibility of electric shock.

2.PARTS REPLACEMENT
This section explains the procedures for replacement of parts, assemblies, and units in the field. Only
the disassembly procedures are explained here. For reassembly, reverse the disassembly procedure.
2.1 Precautions for Parts Replacement
(1) Before starting to replace parts, remove the AC cord and interface cable.
(a) Remove the AC cord in the following sequence:
i) Turn off (
" ") the power switch of the printer.
ii) Disconnect the AC inlet plug of the AC cord from the AC receptacle.
iii) Disconnect the AC cord and interface cable from the printer.
(b) Reconnect the printer in the following procedure.
i) Connect the AC cord and interface cable to the printer.
ii) Connect the AC inlet plug to the AC receptacle.
iii) Turn on ( l") the power switch of the printer.

ON
Reconnect
(2) Do not disassemble the printer as long as it is operating normally.
(3) Do not remove parts which do not have to be touched; try to keep the disassembly to a minimum.
(4) Use specified service tools.
(5) When disassembling, follow the laid out sequences. Parts may be damaged if these sequences are
not followed.
(6) Since screws, collars and other small parts are likely to be lost, they should temporarily be attached
to the original positions during disassembly.
(7) When handling IC's such as microprocessors, ROMs and RAMs, or circuit boards, do not wear
gloves that are likely to generate static electricity.
(8) Do not place printed circuit boards directly on the equipment or floor.

Note: When disassembling and assembling, be careful of the following.
Important:
1. When unplugging the cable , , do not add the excess force. If adding it, solder fracture
in the land of connector occurs and it causes poor connection, and then extraordinary failure
may occur due to the sensor signal defect.
2. Cover Assy When attaching the high voltage power supply 1/ sensor board, the cover assy
top should be removed or opened.

3. Adjustment
This chapter provides explanations on adjustments required when replacing parts. Adjustments are
made by changing parameter values stored in the EEPROM on the main control board. The parameters
can be set on the status monitor. This printer has three kinds of maintenance modes (menus), and it is
necessary to select one of the modes when replacing any parts.
3.1 Administrator Menu
To view Admin MENU, open the Status Monitor and select Printer Settup then click on Open Configuration.
Click on "Display" and put a check next to "Administrator Menu". A pop up will display " Do you want to
display Administrator menu?". Click on Yes. Then scroll down to the Administrator Menu.
