Safety Notices

Important Safety Notices

Prevention of Physical Injury

1. Before disassembling or assembling parts of the printer and peripherals, make sure

that the printer power cord is unplugged.

2. The wall outlet should be near the printer and easily accessible.

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. The printer drives some of its components when it completes the warm-up period. Be

careful to keep hands away from the mechanical and electrical components as the

printer starts operation.

5. The inside and the metal parts of the fusing unit become extremely hot while the printer

is operating. Be careful to avoid touching those components with your bare hands.

Health Safety Conditions

Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it

may cause temporary eye discomfort. Immediately wash eyes with plenty of water. If

unsuccessful, get medical attention.

Observance of Electrical Safety Standards

The printer and its peripherals must be serviced by a customer service representative who

has completed the training course on those models.

Lithium Batteries

Incorrect replacement of lithium battery(s) on the EGB and controller board may pose risk

of explosion. Replace only with the same type or with an equivalent type recommended by

the manufacturer. Discard used batteries in accordance with the manufacturer’s

instructions.

Page 26

CÓPIA NÃO CONTROLADA

Safety and Ecological Notes for Disposal

1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when

exposed to an open flame.

2. Dispose of used toner, the maintenance unit which includes developer or the organic

photoconductor in accordance with 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.

 Use of controls, or adjustment, or performance of procedures other than

those specified in this manual may result in hazardous radiation exposure.

 Turn off the main switch before attempting any of the procedures in the Laser

Optics Housing Unit section. Laser beams can seriously damage your eyes.

 Turn off the main power switch and unplug the printer before you do the procedures

in this section. Laser beams can cause serious eye injury.

3.4.1 CAUTION DECAL LOCATIONS

The caution decal is attached as shown below

 Make sure to turn off the main power switch and disconnect the power plug from the

power outlet before you do any disassembly or adjustment of the laser unit. This

printer uses a class 3B laser beam with a wavelength of 648 to 663 nm and an

output of 9 mW. The laser can cause serious eye injury.

Color Registration Adjustment

 You must manually do the color registration adjustment after you install the new

LDU.

 When the polygon mirror motor or LDB unit is defective, only replace the defective

parts. At this time, if only the motor is changed it is not necessary to do this

adjustment procedure.

1. Print the SMC report with SP 5990 2 before you replace the LDU. Find the values for SP

2181 1, SP 2181 11, 2181 21, and 2181 31.

2. Do SP 2111 2 (Pro. Position Adj > Execute) to roughly adjust the line position after you

install the new LDU. “Result = OK” shows on the LCD if this is done correctly. If not, do it

again until you get “OK”.

3. Do SP2111 3 (Skew Adjust. > Execute) to measure the skew values for each color.

“Result = OK” shows on the LCD if this is done correctly. If not, do it again until you get

“OK”.

4. Check the skew values with SP 2181: Then write down the values. (You can also check

these if you print the SMC report again with SP 5990 2. The values will probably be

different from the values on the report that you printed in step 1.)

 SP 2181 1 for black skew

 SP 2181 11 for magenta

 SP 2181 21 for cyan

 SP 2181 31 for yellow

6. Adjust the skew adjustment cam [A] for each color with a screwdriver. You must adjust

the skew values for each color until they are all the same as the value for magenta that

you found in step 1, before you replaced the LDU.

 For example: If the new value for K (after step 4) is -300 and the old value for

magenta (in step 1) is –250, you must adjust the skew for K until it is -250.

 Turn the cam as shown in the “Cam Rotation Direction” column below to increase

the skew value.

 Turn it in the opposite direction from this to decrease the skew value.

 “Adjustment value” shows the change when you turn the cam one click.

repeat step 3.)

 If these are close to the value for magenta that you found in step 1 (within one click

in the above table), go to the next step. If not, do SP 2111 3 again until you get a

good result.

8. Do SP 2111 1 to finely adjust the line position for each color.

 Try SP 2111 2 if “Result = OK” does not show.

9. When you get “Result = OK”, this adjustment is completed.
