IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. The wall outlet should be near the copier and easily accessible.
2. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main switch is turned off.
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.
4. If the hot roller temperature is low when the main switch is turned on, the
copier starts process control self check automatically. Keep hands away
from the mechanical and the electrical components to avoid any injury.
5. If the start key is pressed before the copier completes the warm-up period
(Start key starts blinking red and green alternatively), keep hands away
from the mechanical and the electrical components as the copier starts
making copies as soon as the warm-up period is completed.
6. The inside and the metal parts of the fusing unit become extremely hot
while the copier is operating. Be careful to avoid touching those
components with your bare hands.
HEALTH SAFETY CONDITIONS
1. Never operate the copier without the ozone filters installed.
2. Always replace the ozone filters with the specified ones at the specified
intervals.
3. Toner and developer are non-toxic, but if you get either of them in your
eyes by accident, it may cause temporary eye discomfort. Try to remove
with eye drops or flush with water as first aid. If unsuccessful, get medical
attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course
on those models.
2. The RAM board on the main control board has a lithium battery which can
explode if replaced incorrectly. Replace the battery only with an identical
one. The manufacturer recommends replacing the entire RAM board. Do
not recharge or burn this battery. Used batteries must be handled in
accordance with local regulations.

SM i A172/A199
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate the toner bottle or the used toner. Toner dust may ignite
suddenly when exposed to open flame.
2. Dispose of used toner, developer, and organic photoconductor according
to local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in order to dispose of them later, do
not put more than 100 batteries per sealed box. Storing larger numbers or
not sealing them apart may lead to chemical reactions and heat build-up.
LASER SAFETY
The Center for Devices and Radiological Health (CDRH) prohibits the repair
of laser-based optical units in the field. The optical housing unit can only be
repaired in a factory or at a location with the requisite equipment. The laser
subsystem is replaceable in the field by a qualified Customer Engineer. The
laser chassis is not repairable in the field. Customer engineers are therefore
directed to return all chassis and laser subsystems to the factory or service
depot when replacement of the optical subsystem is required.
DANGER
Use of controls, or adjustment, or performance of procedures other
than those specified in this manual may result in hazardous radiation
exposure.
WARNING FOR LASER UNIT
DANGER:Turn off the main switch before at tempting any of the
procedures in the Laser Unit section. Laser beams can
seriously damage your eyes.
CAUTION MARKING:
A172/A199 ii SM
INTRODUCTION
The A172/A199 copier (product name: LILY) is based on the A109 copier
(DFC-ALPHA), the base copier.
This documentation gathers the A172/A199 differing points from the base
copier that service personnel will need to maintain this copier. Therefore, this
documentation should be treated as an insert to the base copier’s service
manual, although it has a separate binder. It should always be utilized along
with the base copier’s service manual.
NOTE:Please refer to page 1-9 for machine code/model number
information.
