The controller board contains a CPU (NEC VR4310) and an ASIC (Rocky-W). The
ASIC controls the main memory (SDRAM), engine interface, ROM interface, IEEE1284 parallel interface, and an option bus interface for the NIB. The other option bus interface can be used for upgrading firmware (using an IC card with an
IC card adapter).
There is one optional memory socket that can have either a 16MB or a 32MB SIMM module to increase RAM capacity. With the 32MB SIMM module, the RAM capacity is increased to 40MB.
The flash memory card interface allows the firmware for the controller and NIB to be updated.
The Printer Interface Board (PIF) exchanges video data and operation panel data (LCD, LED, and key data) between the FCU board and the controller board.

2.1 CONTROLLER FUNCTIONS
2.1.1 IMAGE DATA PROCESSIING
Edge smoothing and toner saving are performed by an ASIC (ROCKY W). The edge smoothing and toner saving modes can be switched on/off with the machine’s control panel or the printer driver.

Jagged edges on characters as shown in the above illustration are reduced using edge smoothing. Edge smoothing changes the laser pulse duration and position for certain pixels.
Fig. A shows the four possible pulse durations, and Fig. B shows how the laser pulse can be in one of three positions within the pixel. Fig. C shows an example of how edge smoothing is used.
2-1
CONTROLLER FUNCTIONS |
29 November, 1999 |
Toner Saving Mode
Toner saving is done by reducing the number of black dots in the printed image. An
8 x 8 matrix filter is used.
As a result, less toner is used to create the latent image on the drum and black areas print as gray.
The printer driver prevents edge smoothing and toner saving mode from being used at the same time.
2.1.2 PAPER SIZE/TYPE DETECTION AND SELECTION
The controller uses the paper sizes detected by the print engine for trays 1, 2, and
3. For the by-pass tray, the user has to specify a paper size using the Job Control menu in the Printer User Tools. Refer to section 1.1.2 for details on supported paper sizes.
Thick paper can be selected using User Tools (User Tools – Printer – Job Control Menu).
When the printer controller receives a print job, the controller prints using the paper size specified in the PJL or PCL commands and the paper type specified in the
PCL commands.

H144D601.WMF
Detailed Descriptions
The controller searches for the specified paper size and paper type, starting from Tray 1, and uses the first tray that has the specified paper size and paper type. If the selected tray is pulled out or paper runs out during printing, the controller searches for another tray with the specific paper size and paper type then if found, automatically switches to it. If the controller cannot find another paper tray with the specified paper size and paper type, printing stops and the LCD displays the message “Load Tray xx [paper size]”.
Manual Tray Select

Tray 2 (optional)
Start of Tray Search
(Tray selected by the driver)
Tray 3 (optional)
H144D602.WMF
When the printer driver specifies a tray, the selected tray becomes the first tray checked at the start of the tray search. If the selected tray does not have the size and type of paper specified by the driver, the controller searches the other trays for the same paper size and paper type.
NOTE: Tray Priority in the Job Control menu does not specify the start of the tray search, but specifies the paper size in the selected tray as the default paper size.
Tray Lock
If Tray Lock is enabled for a tray, the controller does not use the “locked” tray in the tray search process. If a tray has, for example, coloured A4 size paper for fax prints, enable tray lock for that tray so that the controller does not select the tray for printing.
2-3
CONTROLLER FUNCTIONS |
29 November, 1999 |
If the printer driver selects a “locked” tray, the controller uses the tray for printing only when the specified paper size matches the actual paper size in the tray.
By-pass Tray
The by-pass tray is not part of the automatic tray search. To print from the by-pass tray, the user has to select the by-pass tray (using either the driver or operation panel). Even if the by-pass tray is empty, the controller will not switch to another tray; the message on the LCD asks the user to add paper to the by-pass tray.
Paper Size Mismatch
When the controller could not find the specified paper size and paper type in any of the trays, the machine displays an error message.
Then the user can either load the requested paper size and paper type in a tray or select another tray, e.g., a tray that contains A4 size paper, by pressing the “Form Feed” key.
The controller will print the job if the specified paper size and paper type are detected in a tray, or if the user presses the Enter key after selecting a tray.
2.1.4 RESET OPERATIONS
Job Reset
This resets the job being processed and ignores all incoming data until a data end is received.
System Reset
This initializes the fonts and macros downloaded to the RAM. The menu settings,
NIB settings, system log data, and error codes remain unchanged. NOTE: Do not use this when the controller is receiving a print job.
Menu Reset
This resets all the menu settings to their default values, including the NIB settings.
2.1.5 ENERGY SAVER MODE
Energy Saver appears in the printer user tool menu, but the setting has no effect. To select an Energy Saver mode, use the fax user tools.
If the paper size and the dial setting is changed when the machine is in energy saver mode, the fax machine will not inform this change to the printer controller.
Then a printing error may occur. This error will then wake up the fax machine, and
2-4
29 November, 1999 |
DETAILED SECTION DESCRIPTIONS |
the new paper settings will be informed to the controller immediately, and the user can try again.
When the machine is in (or recovering from) energy saver mode, the machine always prints a white page if you print out a service report (such as the print log sheet). At the second time, the machine prints a normal page. This is because the fusing unit has not warmed up enough for printing, but the printer controller cannot wait for printing while in service mode.
When the machine is in Night Timer mode, the machine cannot print any data.
