SAFETY WARNINGS
[1] Modifications Not Authorized by
Konica Minolta
Konica Minolta equipment is renowned for their high
reliability. This reliability is achieved through high-quality
design and a solid service network.
Unauthorized modifications involve a high risk of degrading performance and safety. Such modifications are therefore strictly prohibited. The points listed below are not
exhaustive, but they illustrate the reasoning behind this
policy.
PROHIBITED ACTIONS :
(1) Using extension cables or a different power cord
than specified by Konica Minolta.
(2) Using other fuses than specified by Konica
Minolta. Safety will not be assured, leading to a
risk of fire and injury.
(3) Disabling fuses or bridging fuse terminals with
wire, metal clips, solder or similar. (This applies
also to thermal fuses.)
(4) Removing air filters (except for replacement).
(5) Disabling relay functions (such as wedging pa-
per between relay contacts, etc.).
(6) Disabling safety functions (interlocks, safety cir-
cuits, etc.). Safety will not be assured, leading to
a risk of fire and injury.
(7) Performing actions to equipment not described
in the instruction manual or the service hand-
book.
(8) Using parts other than specified by Konica
Minolta.
[2] Checkpoints When Performing On-
site Service
Konica Minolta equipment is extensively tested before
shipping, to ensure that all applicable safety standards
are met, in order to protect the customer and customer
engineer from the risk of injury. However, in daily use, any
electrical equipment may be subject to parts wear and
eventual failure. In order to maintain safety and reliability,
the customer engineer must perform regular safety checks.
(3) Be sure to disconnect the power cord of the
equipment from the AC outlet.
Simply turning off the power switch is not sufficient, because paper feed units or other electrical equipment may be powered also when the
power switch is turned off.
(4) Proceed with special care when performing op-
eration checks or adjustment while the unit is
powered. When carrying out operation checks or
adjustment while external covers are removed,
the risk of electrical shock exists when touching
parts which carry high voltage or electrical charge.
The risk of injury exists when touching moving
parts such as gears or chains.
2. Safety Checkpoints
The following list is not exhaustive, but it includes actions
which must be carried out at every on-site service.
CAUTION:
(1) Check external covers and the frame for sharp
edges, burrs, or nicks.
(2) Check external covers and hinges for loosening
or damage.
(3) Check wiring for squeezing or damage.
(4) Check power cord for insulation problems (con-
ductor must not be exposed).
(5) Check power cord and cable ties etc. for loosen-
ing from frame.
WARNING:
(1) Verify that the equipment is properly grounded. If
a problem is detected, establish a proper ground
connection.
(2) Connecting the ground lead to an improper point
such as listed below results in a risk of explosion
and electric shock.
Unsuitable ground points:
- Gas pipe
- Lightning rod
- Telephone line ground
- Plastic water pipe or water pipe or faucet that
has not been approved by authorities for
grounding use
1. Advance Preparation for Safety Checks
CAUTION:
(1) Wear clothing that facilitates work and is de-
signed for safety.
(2) Carry out all procedures carefully to prevent in-
jury.
3. Description of Safety Checks
CAUTION:
(1) Before performing safety check work, read all
relevant documentation (service handbook, technical notices, etc.) and proceed according to the
prescribed procedure, using only the prescribed
tools. Do not carry out any adjustments not
described in the documentation.
Page 8
(2) If the power cord is damaged, replace it only with
the specified power cord. If the power cord insulation has been damaged and there are exposed
sections, short- circuits and overheating may
occur, leading to a serious fire risk.
(3) Do not route the power cord so that it can be
stepped on or pinched. Otherwise overheating
may occur, leading to a serious fire risk.
(4) When disconnecting any cables, always grasp
the connector and not the cable (especially in the
case of AC and high-voltage leads).
(5) Carefully remove all toner remnants from electri-
cal parts, electrodes, etc.
(6) Make sure that wiring cannot come into contact
with sharp edges, burrs, or other pointed parts.
(7) Double-check to make sure that all screws, com-
ponents, wiring, connectors, etc. that were removed for safety check maintenance have been
reinstalled in the original location. (Pay special
attention to forgotten connectors, pinched cables,
forgotten screws, etc.)
(8) When installation and preventive maintenance,
verify that the power cord has been securely
plugged into the AC outlet. Contact problems
may lead to increased resistance, overheating,
and the risk of fire.
WARNING:
Before disassembling or adjusting the equipment, make sure that the power cord has been
disconnected.
[4] Measures to Take in Case of an
Accident
(1) If an accident has occurred, the distributor who has
been notified first must immediately take emergency
measures to provide relief to affected persons and to
prevent further damage.
(2) If a report of a serious accident has been received
from a customer, an on-site evaluation must be
carried out quickly and Konica Minolta must be
notified.
(3) To determine the cause of the accident, conditions
and materials must be recorded through direct onsite checks, in accordance with instructions issued
by Konica Minolta.
(4) For reports and measures concerning accidents,
consult your superior, and follow the regulations set
in "Standards for the Control Program for Measures
Against Electrical Equipment Accidents".
[5] Conclusion
(1) Safety of users and customer engineers depends
highly on accurate maintenance and administration.
Therefore, safety can be maintained by the appropriate by the proper daily service work conducted by the
customer engineer.
(2) When performing service, equipment on the site
must be tested for safety. The customer engineer
must verify the safety of parts and ensure appropriate management of the equipment.
[3]
Handling of Materials for Servicing
CAUTION: Alcohol-based and acetone- based
cleaners are highly flammable and
must be handled with care. When
using these materials for cleaning
parts, observe the following precau-
tions.
(1) Disconnect the power cord from the AC outlet.
(2) Use only a small amount of cleaner at a time and
take care not to spill any liquid. If this happens,
immediately wipe it off.
(3) Perform cleaning only in an environment where
sufficient ventilation is assured. Breathing large
quantities of organic solvents can lead to discomfort.
(4) Do not replace the cover or turn the unit on before
any solvent remnants on the cleaned parts have
fully evaporated.

1. Operation
a. Automatic sheet feeding (online)
(1) When the main body's START button turns ON,
M201/M202 (tray up/down/U/L) are driven in forward, which lifts the Up/down plate/U/L until
PS204/PS209 (tray upper limit/U/L) are activated.
(2) Concurrently, while M203 (PI conveyance) is
driven at low speed, SD201/SD202 (sheet feed/
U/L) and MC201/MC202 (conveyance/U/L)
come ON and sheets are fed into the FNS
stacker.
(3) When the last sheet on the Up/down plate/U/L is
fed and PS203/PS208 (sheet setting/U/L) come
OFF, the no-sheet-signal is sent to the main
body, causing the first feed of main body to stop.
After that, when PS202/PS207 (no sheet/U/L)
come OFF, M201/M202 (tray up/down/U/L) are
driven in reverse, which lowers the Up/down
plate/U/L until PS205/PS210 (tray lower limit/U/
L) are activated.

(2) Concurrently, while M203 (PI conveyance) is
driven at low speed, SD202 (sheet feed/L) and
MC202 (conveyance/L) come ON and all sheets
set in the Up/down plate/L fed into the FNS
stacker.
(3) The FNS carries out the required finishing pro-
cesses (stapling, three-folding, etc.).
(4) PS207 (no sheet/L) comes OFF, M202 (tray up/
down/L) is driven in reverse, which lowers the
sheet tray until PS210 (tray lower limit/L) is activated.

speed to high-speed. At this time, as MC203
(registration) turns OFF, the sheet is pressed
against the conveyance rollers /U/L to form a
loop. MC203 turns ON when a specified time has
passed since PS201/PS206 turned ON, and the
drive force of M203 is transmitted to the conveyance rollers /U/L. This causes the sheet whose
bend is corrected by loop formation to be conveyed into FNS.
When the sheet turns PS206 OFF, MC203 turns
OFF after a specified time. With the same timing,
MC203 changes its rotating speed to low-speed
and comes into feeding operation for the next
sheet.
