Introduction
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conduc-
tive surface, such as aluminium 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 conduc-
tive foam, aluminium 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.
Super Capacitor or Lithium Battery Precautions
1. Exercise caution when replacing a super capacitor or Lithium battery. There could be a dan-
ger 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 manu-
facturer.
3. Super capacitor or Lithium batteries contain toxic substances and should not be opened,
crushed, or burned for disposal.
4. Dispose of used batteries according to the manufacturers instructions.
Toner Cartridge Service
Only toner cartridges supplied by Xerox should be used. Printing defects or set damage caused
by the use of non-approved print cartridges or un-licensed toner refills are not covered by the guar-
antee.
Precautions on Safe-keeping of Print Cartridge
Excessive exposure to direct light for more than a few minutes may cause damage to the car-
tridge.
Service for the Life of Print Cartridge
If the printed image is light due to the toner supply becoming low you can temporarily improve the
print quality by redistributing the toner (Shake the print cartridge), however you should replace the
print cartridge to solve the problem permanently.
