1. Precautions

Follow these safety, ESD, and servicing precautions to prevent personal injury and equipment damage.

1-1 Safety Precautions

1.Be sure that all built-in protective devices are in place. Restore any missing protective shields.

2.Make sure there are no cabinet openings through which peopleparticularly childrenmight insert fingers or objects and contact dangerous voltages.

3.When re-installing chassis and assemblies, be sure to restore all protective devices, including control knobs and compartment covers.

4.Design Alteration Warning:

Never alter or add to the mechanical or electrical design of this equipment, such as auxiliary connectors, etc. Such alterations and modifications will void the manufacturer's warranty.

5.Components, parts, and wiring that appear to have overheated or are otherwise damaged should be replaced with parts which meet the original specifications. Always determine the cause of damage or overheating, and correct any potential hazards.

6.Observe the original lead dress, especially near sharp edges, AC, and high voltage power supplies. Always inspect for pinched, out-of- place, or frayed wiring. Do not change the spacing between components and the printed circuit board.

7.Product Safety Notice:

Some electrical and mechanical parts have special safety-related characteristics which might not be obvious from visual inspection. These safety features and the protection they provide could be lost if a replacement component differs from the original. This holds true, even though the replacement may be rated for higher voltage, wattage, etc.

Components critical for safety are indicated in

the parts list with symbols . Use only replacement components that have the same ratings, especially for flame resistance and dielectric specifications. A replacement part that does not have the same safety characteristics as the original may create shock, fire, or other safety hazards.

Precautions

1-2 ESD Precautions

Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called "Electrostatically Sensitive (ES) Devices", or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor "chip" components.

The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.

CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

1.Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test.

2.After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.

3.Use only a grounded tip soldering iron to solder or desolder ESDs.

4.Use only an "anti-static" solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges sufficient to damage ESDs.

5.Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.

6.Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conductive material.

7.Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.

8.Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.

9.Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting one's foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.

1-3 Lithium Battery Precautions

1.Exercise caution when replacing a Lithium battery. There could be a danger of explosion and subsequent operator injury and/or equipment damage if incorrectly installed.

2.Be sure to replace the battery with the same or equivalent type recommended by the manufacturer.

3.Lithium batteries contain toxic substances and should not be opened, crushed, or burned for disposal.

Installation

CONFIGURE

Your SF6000 Series MFP can print, scan, and fax. It appears to your Windows computer as three separate peripherals: a Printer, Scanner, and a Fax Modem. These three peripherals appear to be three separate ports on the cable that attaches the SF6000 Series MFP to your computer. These three SF6000 Series MFP ports are configured automatically during installation. The cable is also configured automatically to attach to your computer's LPT1 during installation. However, you can change the Cable, Print or Fax configuration by pressing the Configure button.

Cable Port: This is the computer port to which you connect the SF6000 Series MFP cable. It is configured automatically to LPT1 during installation. LPT1 is also configured automatically to use IRQ (7) and DMA (channel 3) in Windows 3.x. You can connect the SF6000 Series MFP cable to another LPT port on your computer. You can also change the IRQ and DMA assignments for the LPT port in Windows 3.x. Please consult your computer hardware documentation for the appropriate IRQ and DMA assignments. You must restart Windows after you make changes to the Cable Port LPT, IRQ, or DMA configuration. The new assignments will become effective when Windows restarts.

Print Port: This port is pre-configured to LPT3 in Windows 3.x or LPT4 in Windows 95. You print Windows documents on the SF6000 Series MFP by connecting the SF6000 Series MFP printer driver to this Print Port. You only need to change the configuration of the Print Port if the LPT3 or LPT4 assignments are in conflict with your PC hardware or software. You can select another configuration of the Print Port between LPT2 and LPT9. When you change the Print Port configuration you will also need to open the Windows Printer Control and reconnect the SF6000 Series MFP printer driver of the new LPT assignment. You must restart Windows after you make changes to the Print Port configuration. The new assignment will become effective when Windows restarts.

Scan Port: This port is pre-configured to COM9 in Windows 3.x and Windows 95. Your SF6000 Series MFP Scanner software is automatically configured to connect to COM9. This assignment is fixed.
