Chapter 1 Safety Instructions
1-1
1. To Avoid Hazards to Human Beings
1.1. DC Fan
There is a cooling fan and its ventilation window at the bottom of the PS-7000. Please avoid
touching it, as it can get extremely hot especially during or immediately after use of the machine.
Also, please be careful not to cover the ventilation window with anything such as rich fur carpet.
It can cause malfunction.
1.2. Edges
Please be careful of edges of the External Covers and Stand, when carrying the PS-7000 or servicing
it. All the External Covers and Stand are made of metal.
1.3. Power Supply
To avoid electrical shock hazards, be sure to remove the power cord before disassembling the
PS-7000 for service. An AC power is directly supplied to the primary side of the Power Supply unit.
When supplying power during service, such as to perform the DIAG program (see page 3-10), please
take extreme caution.

1-2
2. For Correct Operation of PS-7000
2.1. Shock during operation
Please avoid shock to the PS-7000 during operation. As the PS-7000 has an HDD installed, shock to
it can destroy the HDD itself as well as the data being processed.
2.2. Power operation
Please avoid turning off the power during operation of the HDD. Power-off during access to the
HDD can destroy user-downloaded data such as font data. Turn off the power after the HDD LED is
turned off.
2.3. Placement
Please install the PS-7000 on the right position. Laying it or incorrect placing of it can cause
unexpected problems.

3. Notes on Installation
3.1. Place of installation
-Avoid placing the PS-7000 on unstable surface or those that can vibrate, to prevent the machine from
falling.
-Avoid covering the ventilation window (at the bottom) with anything. Place the machine 10 cm or
more away from the wall. Insufficient ventilation can cause malfunction.
-Keep the machine away from humidity, dust, direct sun light, heat or flame, to avoid fire or electrical
shock hazards. Use the machine in the operating environment 5 to 35˚C and 20 to 80%RH without
any dew condensation.
-Keep the machine away from flammable liquids such as alcohol and thinner, to avoid fire or electrical
hazards.
3.2. Power Supply
- Do not touch the power cord with wet hands, to avoid electrical shock hazards.
-Plug in the power cord until it touches the end. Insufficient plugging can cause fire or electrical shock
hazards.
-Do not use any power cords other than that packed with the PS-7000. Use of any other power cord
can cause fire or electrical shock hazards. Do not use the packed power cord with other equipment.
-Do not modify, pull, or bend the power cord, or place the power cord under heavy materials. Current
can leak from where the power cord is scratched, and it can cause fire or electrical shock hazards.
- Avoid multiple wiring with use of Y-shaped cable. It can cause fire or electrical shock hazards.
- Do not put anything around the AC outlet so that the power supply plug can be removed immediately in
case of emergency. Delay in removing the plug can cause fire or electrical shock hazards.

3.3. Installation procedures
Please refer to the “Canon Hardware RIP PS-7000 Operator’s Manual.”
3.4. Check after installation
Perform Test Print to check if the machine is installed correctly.
(For details, please see page 3-12.)

4. Special Notes at Maintenance Service
4.1. Main Board
4.1.1. EEPROM
-When replacing the Main Board
Be sure to remove the EEPROM (IC18) from the socket of the old
Main Board and re-install it on the new one.
-When replacing the EEPROM
If customers have downloaded commercial fonts, some of them cannot be
downloaded again to a replaced new EEPROM (*1).
In those cases, a new master disk of the fonts or a new installation disk
of the fonts is required.
If no commercial fonts are downloaded, the EEPROM can be replaced for
use without any special requirement.
<Information stored in EEPROM>
- Parameters and values used by the PostScript system
- ID number (*1) used at downloading of fonts
No method is available to see, to back up or to recover those information.
*1: At the first initialization of machine, Adobe PostScript system writes to the EEPROM a value unique to each
machine, based on random numbers, as ID number. Some downloadable commercial fonts use this ID
number to protect downloading to other machines, by recording the ID number in the font installation disk at
the first downloading and by matching it with the one in the EEPROM at every downloading thereafter.

4.2. HDD
1) Replacement or format
Before replacing or formatting the HDD, please be sure to notify customers that data downloaded
by customers, such as fonts, can be lost.
2) Service part HDD
Service part HDD have already been formatted, and there is no need to format it again before use.
(For HDD formatting, please see page 4-13.)
Notes: The HDD format used in this manual is for recognition by PostScript system,
and it is completely different from that performed under Windows (DOS) or
Macintosh.
3) Master / Slave setting
If an additional HDD is installed, the jumper must be set as shown below to identify the slave
HDD from the master HDD.
4.3. Network Board
After replacement of the Network Board, network-related parameters such as IP address must be set
again. For setting the IP address, use the TCP/IP setting utility (Pnconfig) in the CD-ROM (Canon
Hardware RIP PS-7000 CD) packed with the product.
4.4. Prevention against electrostatic destruction
When disassembling the PS-7000, please place it on the conductive mat (or sheet) and put on the wrist
belts for a ground. The PCB, memory modules, and HDD used for the PS-7000 are weak to static
electricity.
