Operational Theory
Interlock Mechanism
When the front cover assembly, fuser cover or cartridge cover is
open, a CLOSE DOOR message displays indicating the interlock
system is open.
If the front door assembly or the fuser cover are closed, the door
switch actuator 3 [A] moves in the direction of arrow [B].
When the cartridge door is closed the door switch actuator 1 [C]
rotates in the direction shown by arrow [D] and activates the door
switch [E] and laser switch [F].
If either of these doors are not closed, actuator 1 [C] will not rotate
and the switches will not turn on.
When door switch [E] is not activated, it prevents the LVPS from
supplying power to the printer.
When the laser switch [F] is not activated, the engine board will not
turn the printhead on.

Sheet Bypass Paper Feed Unit
Operation of the sheet bypass paper feed unit (multipurpose tray)
When the sheet bypass tray is closed and printing is started,
revolution of the developer/paper feed motor is transmitted to the
clutch gear and timing clutch gear of the sheet bypass paper feed
assembly.
When the bypass paper feed clutch activates, the sheet bypass
paper transfer roll is lowered and touches the paper in the tray.
When the paper transfer roll touches the paper in the paper tray, the
paper is fed into the printer by the actions of the paper transfer roll
and paper feed roll.
As paper is fed to the timing roller by the sheet bypass paper feed
roll, the paper pass sensor detects paper is present. This sensor is
located just prior to the timing roller. After the paper is detected, and
passes through the sensor, the sheet bypass clutch turns off, and
the sheet bypass paper feed and sheet bypass paper transfer roller
stop rotating. At the same time, the paper transfer roller is lifted up
by the return spring so that the paper will touch the timing roll and
wait.
Note: If the transparency paper sensor located in front of the timing
roller detects a transparency, the printer slows to the half speed
mode.
At the same time the image is transferred from the organic photo
conductor (OPC) to the transfer belt, the timing clutch turns on and
the timing roll begins rotating. Paper is then fed into the image
transfer area, registering the image on the sheet of paper.
Double feed prevention
The double feed prevention pad contacts the sheet bypass
paper feed roller at a specific pressure. Whenever multiple sheets of
paper are fed, the bottom sheet is stopped by friction of the double
feed prevention pad, which aids in preventing double feeding. Only
the top sheet of paper is fed by the paper feed roller.
The paper pass sensor checks paper fed from the sheet bypass
paper feed assembly. If the sensor does not detect paper during a
specific time, a paper jam error displays.
General Information 1-9
5016-001
Detecting paper present
A sheet of paper in the sheet bypass tray is detected by the sheet
bypass paper detect sensor. When the sheet of paper is detected,
the paper detect sensor turns off. When the sheet of paper is not
detected, the sensor turns on.

Paper Feed Unit
Operation of the paper feed unit (tray 1)
When the paper cassette (tray 1) is present in the printer, a flag
molded in the right side of the tray contacts the release lever rotating
the paper transfer roll, allowing it to contact the paper in the tray.
When a print command is sent to the printer, the paper feed clutch,
attached to the paper feed roller turns on, which turns the main
motor transmitting to the clutch gear magnet and the paper feed
gears, causing the paper feed roller and paper transfer roller to turn.
Double feed prevention
The double feed prevention pad contacts the sheet bypass paper
feed roller at a specific pressure.
Whenever multiple sheets of paper are fed, the bottom sheet is
stopped by friction of the double feed prevention pad which aids in
the prevention of double feeding. Only the top sheet of paper is fed
by the paper feed roller.
As paper is fed to the timing roller by the paper feed roll, the paper is
detected by the paper pass sensor located just ahead of the timing
roller. After the paper is detected, the paper feed clutch turns off and
the paper feed roller and paper feed transfer roller stop rotating. At
this point the paper touches the timing roller and remains. The paper
pass sensor checks the paper feed from the cassette; if paper is not
detected the printer stops and a paper jam error displays.
Detecting the paper
Paper in the casette is detected by the paper detect sensor. When
the paper is detected the sensor turns off. If paper is not detected
the sensor remains off.
Detecting paper level
The amount of paper remaining in tray 1 is detected by the paper
detect sensor. When there is enough paper in tray 1 the sensor
remains off. When the level is low, less than 50 sheets, the sensor
turns on and Load Paper tray 1 displays.
General Information 1-11
5016-001
Detecting paper size
Paper size is determined by the paper size detect plate connecting

Second Paper Feed Unit (Optional Paper Trays)
Construction of the Second paper feed option
The second paper feed unit consists of two separate feed units
which are the same as the paper feed unit for tray 1, along with idler
rollers above the paper feed units and paper guides on the side of
the paper feed opening. The interconnect board assembly, drive
module and LVPS for the option is located on the right side frame.
General Information 1-13
5016-001
Operation of the Second paper feed unit
When the paper cassette (tray 1) is placed in the printer, a flag
molded to the right side of the tray, contacts the release lever which
rotates the paper transfer roll allowing it to contact the paper in the
tray.
When the command is given to start printing, the optional paper tray
stepper motor rotates, rotating the respective reduction gears. The
rotating reduction gears cause the gears attached to the paper feed
roller and paper transfer roller to start rotating. The paper feed roller
contacts the paper causing the paper to feed to the idler roller. The
one way clutch causes the idler roller to rotate feeding the paper
past the paper pass sensors located prior to the idler roller and the
timing roller. After a predetermined period of time, the paper feed
clutch is turns off and the paper feed roller and paper transfer roller
stop rotating. At this point, the paper stops at the timing roller and
pauses. If the pass thru sensors do not detect paper from the
cassette, a paper jam displays.

Intermediate Transfer Unit
Function of the intermediate transfer unit
The intermediate transfer unit consists of the transfer belt, belt
cleanser and waster toner bottle in which cleaned toner is collected.
The transfer belt is made of an electrically conductive resin. The
toner image, when placed on the organic photoconductor (OPC)
drum is transferred onto the transfer belt by an electric field. The belt
makes four turns, so that four color toner images, yellow (Y),
magenta (M), cyan (C) and black (BK) are transferred onto the belt.
The color image is formed on the transfer belt and the entire image
is transferred onto paper by the transfer roller forming the color
image on the paper.
Note: While the four color toner images are still on the transfer belt
the transfer roller, discharge roller and cleaning roller are pulled
away from the transfer belt. An optical reflector is attached on one
edge of the outer circumference of the transfer belt and is used by
the home position sensor to detect the position of the belt. After the
image is transferred to the paper, any toner remaining on the belt is
cleaned by the cleaning roller and transferred through the transport
coil into the waste toner bottle in the belt unit. When cleaning the
remaining toner, after the image has been transferred to paper, the
transfer roller, discharge roller and cleaning roller, touch the transfer
belt.
1-24 Service Manual
5016-001
The waste toner bottle is partitioned and collected toner is
transferred into respective partitions in order. When the bottle is
filled to capacity, it is detected by the waste toner bottle full sensor.
The cleaner consists of the discharge roller, cleaning roller, blade
and toner transport coil. The toner remaining on the belt is
discharged by the discharge roller, transferred to the cleaning roller,
scraped from the cleaning roller by the cleaning blade and
transported to the waste toner bottle by the transport coil.

Fuser/Paper Exit Unit
Operation of the fuser and paper exit
When the power switch is turned on the fuser lamp is turned on by
the low voltage power supply while the hot roll begins to heat.
When the hot roll reaches approximately 170 degrees C the fuser
drive motor is turns on and the backup roll, hot roll and paper exit
rollers start turning. After a specified time the fuser drive motor turns
off and the printer is ready to print.
The thermistor continuously detects the temperature of the surface
of the hot roll, turning the fuser lamp on and off keeping the surface
of the hot roll at a specified temperature.
After the last sheet of paper prints and the paper exit sensor detects
the exit of the sheet of paper, the fuser drive motor turns off and the
backup roll, hot roll and paper exit roll stop turning.
A thermostat is provided to protect the fuser unit should an unusual
rise in temperature occur in the hot roll assembly. If activated, the
thermostat shuts off power to the fuser lamp.
A cleaner unit is located on top of the hot roll. The oil roller in the
cleaner unit supplies a specified amount of oil to the hot roll
preventing an offset. The cleaning roller prevents the hot roll from
becoming dirty from a buildup of toner or paper dust.
If power is applied to the fuser unit and a cleaner unit has not been
installed, the paper exit sensor lever is detached from the paper exit
sensor and the printer proceeds to the paper jam state, preventing
the hot roll, backup roll and paper exit roller from rotating.
General Information 1-27
5016-001
Detecting New Cleaning Unit
Detecting the cleaning unit in the Fuser Assembly
A thermal fuse is attached on the contact point A in the cleaner unit.
When the cleaner unit is placed inside the fuser unit, contact A
contacts contact B. The circuit is then complete through the thermal
fuse. When primary power is applied to the printer, a current flows
through the thermal fuse detecting a new cleaner unit and the print
counter resets to ‘Zero.’
As the temperature of the hot roll and cleaning roll rise, the
temperature around the thermal fuse also rises, eventually causing
the thermal fuse to blow.
Note: The fuse will generally blow after primary power has been
applied following the printing of two or three sheets of paper. At this
time the temperatures of the blown fuse and surrounding parts are
70 degrees C and about 100 degrees respectively.
When predetermined sheets of paper are printed, a warning
displays. When additional sheets are printed, the printer stops until
the unit is replaced. When a new unit is placed, repeat the previous
step.

Duplex Unit (Option)
One side print
The print fed by the paper feed rollers in tray 1 in the printer and in
the second paper feed unit is halted temporarily at the timing roller
for registration. The paper then passes through the transfer unit, in
which the image is formed, and is fused in the fuser assembly. When
the paper exit sensor detects paper, the drive of the automatic two
sided print unit starts, switching the gate claw to the outer side to
eject the page. The paper that is transported by the paper exit roller
in the printer is ejected into the paper exit tray by the paper exit roller
in the duplex unit.

back page is printed. The paper then passes through the fuser roller.
When the leading edge of the paper reaches the paper exit sensor in
the fuser, the upper unit motor starts rotating in the normal direction,
switching the gate claw to the inner side to receive the paper. When
the paper reaches the upper paper pass sensor, through the paper
transport roller, the rotation of the motor is switched to the
high-speed mode. At the same time, the lower unit motor begins
rotating in the normal direction in the high speed mode, transporting
the paper to the storage area in the lower unit through the rear unit.
1-30 Service Manual
5016-001
When the trailing edge of the paper passes through the reverse
sensor filler (S4], the motor rotates in the reverse direction
transporting the paper in reverse. The print is transported to the
timing roller in the printer through the rollers in the curved area, the
skew correction mechanism and the paper feed roller. The paper is
then fed through the transfer and fuser units in sync with the image
of the front page as it is transported onto the middle transfer unit.
When the leading edge of the paper reaches the paper exit sensor
[S0] in the printer, the upper unit motor starts rotating in the reverse
direction, switching the gate claw to the paper exit mode. The paper
then exits through the paper exit roller in the upper unit.
General Information 1-31

The back page of the first printed page is printed after Print Start is
pressed. The print is received in the upper unit through the above
step and then halted when it reaches the paper exit sensor [S5]
through the storage, reverse and skew correction mechanisms in the
lower unit. The second page is then fed from the selected paper tray
and its back page is printed and transported to the upper unit. The
second page stops when it reaches the upper paper pass sensor
[S2] and is held there. The first page waiting in the lower unit is fed
to the timing roller in the printer. When the timing roller rotates, the
motors in the upper and lower units rotate in high speed mode,
transferring the second page, waiting in the upper unit, to position in
the lower unit. At this time, the front page of the first page is printed
and then exits the printer. The printer then prints the front page of
the second page and finally the second page, as it is finished, exits
the printer.

Print Tests
The purpose of the diagnostic Print Tests is to verify that the printer
can print on media from each of the installed input options. Each of
the installed options is listed in the following order in the menu:
For each input source selected, the following choices are available:
Single (prints the Print Test Page once).
Continuous (continue printing the Print Test Page until Return or
Stop is pressed).
•
•
•
•
Tray 1 = Single, Tray 1 = Continuous
Tray 2 = Single, Tray 2 = Continuous (if installed)
Tray 3 = Single, Tray 3 = Continuous (if installed)
MP Feeder = Single, MP Feeder = Continuous
The contents of the Print Test Page vary depending on the media
installed in the selected input source. If a source is selected that
contains Paper, Legal, Letter and so on, a page similar to the Quick
Test Page is printed. However, the page does not contain the print
registration diamonds. If an input source is selected which contains
envelopes, an Envelope Print Test pattern is printed. This pattern
contains text only, consisting of continuous prints of each character
in the selected symbol set.
If continuous is selected, all sources printing with paper sizes print
the same page continuously until the test is stopped. If continuous is
selected for a source containing envelopes, the envelope print test
pattern prints on the first envelope and subsequent envelopes are
blank.
Note: The Print Test Page may be printed on any paper or envelope
size, however more than one sheet of some media sizes may be
required. The Print Test Page is always simplexed, regardless of
duplex settings or the presence of the duplex unit.

Handling ESD-Sensitive Parts
Many electronic products use parts that are known to be sensitive to
electrostatic discharge (ESD). To prevent damage to ESD-sensitive
parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic boards:
• Keep the ESD-sensitive part in its original shipping container
•
•
•
•
•
•
•
(a special “ESD bag”) until you are ready to install the part into
the printer.
Make the least-possible movements with your body to prevent
an increase of static electricity from clothing fibers, carpets, and
furniture.
Secure the ESD wrist strap around your wrist and connect the
wrist band to the engine ground point. This discharges any
static electricity, in your body, to the printer.
Hold the ESD-sensitive part by its edge connector shroud
(cover); do not touch the pins. If you are removing a pluggable
module, use the correct tool.
Do not place the ESD-sensitive part on the printer cover or on a
metal table, as electrical grounding may occur, which increases
the risk of damage due to the discharge path your body could
establish through the ESD-sensitive part. (Large metal objects
can be discharge paths without being grounded.)
When laying the ESD-sensitive part down, always return it to
the ESD-sensitive bag.
If possible, keep all ESD-sensitive parts in a grounded metal
cabinet (case).
Take care working with ESD-sensitive parts when cold weather
heating is used, as low humidity increases static electricity.
