CONTENT

The new model (FC25P) is a product using the present model (FC15, FC22) as the base for the printer. This BSI is to substitute for a Service Manual by specifying the differences.

Elimination of optical system

Printer control only

[Differences]

The following table clarifies the differences in the table of contents of the Service Manual of the FC15 and the FC22.

o : Parts common to the FC25P

#1 : A separate explanation for the FC25P is added.

#2 : There is no optical system so some part of the contents have become unnecessary for the

FC25P.

x : FC25P unnecessary parts --- Letters in italic

The pages indicated by the sign #1, #2, X are appended as a separate file.

1 Charging: Places a negative charge on the sur-

face of the photoconductive drum.

Original exposure: Converts images on the original into optical signals.

Data reading: The optical image signals are read into CCD and converted into electrical signals.

4 Data writing: The electrical image signals are

changed to light signals (by laser emission) which expose the surface of the photoconductive drum.

5 Development: Negatively-charged toner is

made to adhere to the photoconductive drum, producing a visible image.

6 Transfer/separation: Transfers the visible toner

image onto paper, and separates the paper with the toner image from the photoconductive drum.

7 Fusing: Fuses the toner image to the paper by

applying heat and pressure.

8 Conductive blade cleaning : While scraping off

the residual toner from the drum, this blade also eliminates the (+) residual charge on the drum left after image transfer.

9 Discharge LED array: Eliminates the residual

(–) charge from the surface of the photoconductive drum.

(3) Data reading (scanning) Data reading is the process of illuminating the original with light and converting the reflected light into electrical signals.

CCD board

The light reflected from the original is directed to the charge coupled device (CCD) and this optical image information is converted to electrical signals (image signals), which are then sent to the image processing section via the scanner control PC board. The CCD for color processing has RGB filters provided over its surf ace, which allow the CCD to read the light amount in the respective ranges of wavelength. The image data corresponding to the respective RGB colors is then sent to the image processing section.

(4) Data writing Data writing is the process of converting the image signals light signals and exposing the drum surface with the light signal. Namely, the image signals sent from the image processing section are converted into optical signals (laser emission) by the semiconductor laser element, which are then used to expose the drum surface, thus forming an electrostatic latent image there.

plate)~The exposure lamp OFF.

~ The original size indicator initializes, then displays the original size.

• Initialization of the paper feeding system: ~ The tray of each cassette rises. ~ The guides of the ADU (automatic duplexing unit) detect their home positions, then mo ve to their

maximum-size position.

• Initialization of the laser optical system: ~ The polygonal motor rotates.

• Drum rotation: ~ Drum motors ON, transfer belt motor ON, color de veloper motor ON and b lack de veloper motor

ON.

• Toner supply control: ~ If the toner density in any developer unit is lower than specified, the toner supply mode starts.

• Image quality control: ~ Test patterns are formed on the transfer belt, and based on their reflection factors, the optimal

conditions are set.

• Others: ~ The main charger wire cleaners operate.

• Color registration control: ~ Test patterns are formed on the transfer belt and their signals are read to detect if toner is

present or not. This information is used to correct registrational deviation of each color.

January 2000 © TOSHIBA TEC 4 - 1 FC-22 GENERAL OPERATION

• A sheet of paper reaches the registration roller: ~ Aligning operation takes place.

(3) Carriage operation

• Exposure lamp ON→Shading correction

• Scan motor ON→Carriages 1 and 2 start moving forward.

(4) A fixed time after the carriage operation,

• Registration motor ON→Transports the paper to the transfer section.

• The copy counter operates.

(5)A fixed time after the registration motor has been turned ON, toner supply operation is performed in

the order of Y, M, C and K, and then the transfer roller bias is turned ON.

(6) Carriage scanning completion

• Scan motor OFF

• Exposure lamp OFF

• Registration motor OFF (after the trailing edge of the paper has passed the registration roller)

(7) Paper exit operation

• The trailing edge of the paper is detected by the exit sensor.

• The main chargers, developer bias and discharge LEDs are turned OFF.

• The drum motors, transfer belt motor , fuser motor and de veloper motors stop their oper ations. The fan motors and polygonal motor return to their standby rotations.

• “READY” is displayed and the copier goes into standby.

8.1.2 Control Panel and Display Panel for FC-25P

The display unit is comprised of touch-panel switches and ke y switches , which are used for oper ating the printer and selecting various modes, and LEDs and LCDs, which are used to display the machine status (various modes included) and messages. Normally, only messages are shown on the LCD. However, when the operator needs to be alerted, a corresponding pictorial is lit or flashed on the LCD with a message describing the associated status at the same time.

The main unit is equipped with the same control panel as that on the copier. This allows you to do the same operation as with the copier, when making v arious adjustments during installation. After the adjustment are finished, attach the control-panel cover which came pack ed. Only the service technician should install or remove the control-panel cover.
