OVERVIEW 30 July, 2001 6.1.5 PRINTING PROCESS 2, 6 1 3 5 8 10 4 9 7 G060D151.WMF This machine uses four PCUs, four development units, and four laser beams for color printing. Each PCU consists of a drum, charge roller, cleaning brush, and blade. From the left, the PCU stations are black, yellow, cyan, and magenta. A transfer belt feeds paper past the PCUs, and the toner image on each drum is transferred to the paper.
PAGE 190
OVERVIEW 1) Drum charge: The charge roller gives the drum a negative charge 2) Laser exposure: The laser beam from the laser diode (LD) goes through the lens and mirrors and reaches the drum. Turning the laser beam on and off, and creates a latent image on the drum. 3) Development: The development roller carries negatively charged toner to the latent image on the drum surface. This machine uses four independent development units (one for each color).

PROCESS CONTROL 30 July, 2001 6.2 PROCESS CONTROL 6.2.1 OVERVIEW This machine provides the following two forms of process control: • Potential control • Toner supply control The process control facilities of this machine have the following features: • Two ID (image density) sensors (front and rear). Only the front ID sensor is used for process control. The front and rear ID sensors are used for line positioning and other adjustments. • TD (toner density) sensor. 6.2.
PAGE 192
30 July, 2001 PROCESS CONTROL Process Control Self Check This machine carries out potential control using a procedure called the process control self check. There are seven types of process control self check, categorized according to their execution times. 1. Forced This is done when SP3-126-1 is used. 2. Initial This starts automatically when the power is turned on, but only if the fusing unit pressure roller temperature is less than 60°C. 3.

PAGE 194
30 July, 2001 PROCESS CONTROL Step 2: ID Sensor Solid Pattern Generation 12 mm 15 mm G060D154.WMF The machine agitates the developer for between 15 and 60 seconds until the fluctuation in TD sensor output becomes less than 0.3V, and then makes a 10grade pattern (12 mm x 15 mm) on the transfer belt for each toner color. Each grade of the pattern is a solid color, and is made by changing the development bias and charge roller voltage.
PAGE 195
PROCESS CONTROL 30 July, 2001 • If it is set to 0, the LD power is fixed at the value of SP2-103-1, to -27. • If it is set to 1, LD power is selected using the same memory table as mentioned above. • If it is set to 2, LD power is determined by ID sensor highlight pattern generation (steps 6 to 8 later in this procedure).
PAGE 196
30 July, 2001 PROCESS CONTROL Step 8: VL (LD Power) Selection The machine determines the relationship between the amount of toner on the transfer belt and the laser power for each of the 10 grades. The machine now selects the laser power to get the target M/A. After that, the machine cleans the transfer belt by applying a positive dc charge to the cleaning roller for three rotations of the belt. It does not use the cleaning blade. M/A Target M/A L LD Power Detailed Descriptions G060D003.

PROCESS CONTROL 30 July, 2001 6.2.4 TONER SUPPLY CONTROL Overview Toner supply control uses the following to determine the amount of toner to be supplied. This is done before every development for each color. • Density of the toner in the developer (as detected by the TD sensor) - VREF, VT • Pixel count The image density is kept constant by adjusting the density of toner in the development unit, while accommodating to changes in the development conditions through the potential control mechanism.
PAGE 198
30 July, 2001 PROCESS CONTROL 6.2.5 TONER NEAR END/TONER END DETECTION Introduction The machine is always checking for a toner near end condition. Toner Near End Detection When the following condition is detected for a toner color during a print job, the machine automatically stops the print job and performs toner end recovery. If the result of toner end recovery does not meet the condition described in Toner End Recovery below, the machine flags a “toner near end condition”. • VREF + 0.
PAGE 199
PROCESS CONTROL 30 July, 2001 6.2.6 DEVELOPER INITIALIZATION When the machine detects that a new development unit has been installed, it initializes the developer. To do this, the machine agitates the developer for about 90 seconds, and adjusts VCNT (control voltage for TD sensor) so that VT (TD sensor output) becomes 3.0 ± 0.1 volts. The machine stores this VT as VREF. VCNT is corrected for the current humidity every print job.

DEVELOPMENT 30 July, 2001 6.5.6 TONER SUPPLY MECHANISM [D] [E] [A] [C] [F] [B] G060D313.WMF Overview An air transport system agitates the toner in the toner cartridges [A]. Toner is transported from the toner cartridge to the development unit [B] by the toner attraction pump [C] (each cartridge has a separate pump). This provides a more stable way to transport a fine powder than previous methods.
PAGE 220
30 July, 2001 DEVELOPMENT Toner Transport [B] [C] [D] [E] [A] G060D314.WMF Each toner attraction pump has the following mechanism. The toner supply clutch drives the rotor, which draws the toner in from the cartridge and passes it to the development unit. Each time the clutch comes on to supply toner, it turns on for 0.7 s and off for 1.3 s. The number of times that the clutch turns on depends on the amount of toner to be supplied, which depends on the results of toner supply control.
