1. OVERALL MACHINE INFORMATION

1.1 INTRODUCTION

The base engine (Machine Code: A292/A293 and A294/A295) contains an
interface for the multi-function controller. The multi-function controller adds printer
functions. The printer functions can operate independently and simultaneously with
other functions in the background, and their output can be interleaved with the
copy mode output.

The printer supports PCL6 and PostScript 3. The PostScript language is an
optional function.

Print data from the host is transmitted through the standard parallel port or an
optional Network Interface Board (NIB). The parallel port supports bi-directional
Command and Status feed back communication with the base engine.

An optional IDE hard disk drive provides font download and macro download.
An additional SDRAM can be installed to boost the printer performance.
Print data is rasterized at 600 dpi in the controller.
The A294 and A295 engines can print 85 and 105 pages per minute respectively at

600 dpi. The A292 and A293 engines can print 55 and 70 pages per minu te
respectively at 600 dpi.

B335D503.WMF

CD-R/

RW

The printer controller receives print data from a PC through the parallel or network
interface port. The co-processor handles the print data but it only makes raster
image. All image processing, such as edge smoothing and toner saving, are done
in the base engine.

The print data from the PC goes to the buffer in the SDRAM DIMM and then goes
to the co-processor. The co-processor automatically selects the appropriate printer
language and creates the print data to match the selected printer language. Then,
the co-processor sends the print data to the LD unit through the IPU on the SICU
or BICU board. At the same time, the data is also sent to the hard disk for multiple
printing, as well as for backup in case of a paper jam.

2-3

IMAGE DATA PROCESSING 1 March, 2000

2.3 IMAGE DATA PROCESSING

The FCI in the LD unit is responsible for edge smoothing and toner saving
functions.

The edge smoothing and toner saving modes can be switched on or off using the
printer user tools or the printer driver.

2.3.1 EDGE SMOOTHING

A850D504.WMF

Usually, binary picture processing generates jagged edge on characters (Fig. A).
The FCI reduces the edges of characters using edge smoothing.

Whether a pixel undergoes smoothing depends on the surrounding image data.
Changing the laser pulse position for certain pixels does the smoothing.

2.3.2 TONER SAVING MODE

Toner saving is done by reducing the number of black dots printed, not by varying
the development bias. In toner saving mode, the image data is filtered through a
matrix.

As a result of passing through the filter, less toner is used to create the latent
image on the drum and black areas are printed as gray.

2-4

1 March, 2000 FEATURES

2.4 FEATURES

2.4.1 SORT

If “Collate” is turned on when a multi-set job is printed, the first set of the job is
directly printed. At the same time, the print data for the copy job is stored in the
hard disk of the base engine. The remaining sets are printed using the data in the
engine hard disk.

If the finisher is not installed, the rotate sort feature can be used. The SICU or
BICU rotates the image in the same way as the copy mode.

2.4.2 DUPLEX

Duplex printing is available with all output options such as finisher or mailbox but
not with all paper sizes (refer to the specifications section of the base engine
manual). If the selected paper size is not usable in the duplex mode, the job is
printed simplex.

Two types of duplex binding can be selected. Those are short-edge binding and
long-edge binding.

In short-edge binding, the image may be rotated when printing on the second side
of a sheet of paper. The co-processor in the printer controller does the rotation.

The co-processor corrects the page order for duplex printing as follows:

•

Larger than A4 lengthwise/8

1st page – 3rd page – 2nd page – 5th page – 4th page – 7th page – 6th page –
8th page

”x11” (in the case of 8 pages)

page

2-5

FEATURES 1 March, 2000

2.4.3 STAPLE

The staple function is only available when a finisher is installed.
The finisher has the following stapling positions:

1) Top left slant

2) Top left horizontal

3) Top left vertical

4) Top two staples

5) Left two staples

Depending on the paper orientation, the image may have to be rotated. The co­processor in the printer controller does this image rotation.

There is a limit for the number of sheets that can be stapled by the finisher. If the
number of sheets for stapling is more than the limit, the set is not stapled.

2.4.4 PUNCH

The punch function is only available when a punch unit is installed on the finisher.
There are several types of punch unit, each having different numbers of holes. The
punching position in relation to the printed image depends on the paper feeding
orientation and imaging. The punching positions are as follows:

1) Left

2) Top

2-6

1 March, 2000 FEATURES

2.4.5 JAM RECOVERY

If the jam recovery feature is on and a paper jam occurs, the controller reprints all
the pages that have not been fed out. In usual cases, all image data from the
controller is sent to the hard disk in the base engine. When a jam occurs, the
recovery data is sent from this hard disk.

2.4.6 AUTO TRAY SELECT

When “Auto Select” is selected with the printer driver, the printer searches for a
tray that contains a suitable size and paper type. The search starts from the LCT
as below.

LCT – 1st tray – 2nd tray – 3rd tray

The default setting for the tray priority is LCT. If the LCT is not installed, the default
is the 1st tray.

2.4.7 POWER ON SELF-DIAGNOSTICS

When the main power switch is turned on, the printer controller performs a self­diagnostic test. If an error is detected, an error message is displayed on the LCD of
the operation panel.

HARD DISK 1 March, 2000

2.5 HARD DISK

Two types of hard disk are used for the printer functions. One type is connected to
the printer controller (Printer HDD). Th e other is in the base engine (Engine HDD).

2.5.1 PRINTER HDD

After installing the printer HDD, it must be formatted. When the main power switch
is turned on and the printer mode key is pressed, the hard disk can be formatted.

When the Con tinue button is pressed, the hard disk is formatted and two partitions
are made. One partition is for PCL and the other is for PostScript (fonts and
macros only).

If the Cancel button is pressed, it is judged that the printer HDD is not installed. If
the Cancel button is pressed by mistake, the printer HDD ca n be formatted by
turning the main power switch off and on or entering the Service Program (SP)
mode.

2.5.2 ENGINE HDD AND CD-R/RW

The hard disk in the base engine is used for the copy, printer, and document server
modes. Therefore, the hard disk has three partitions for each mode. (Refer to HDD
Control in the base engine manual.)

Print data can be saved on the HDD (document server) and on the CD-R/RW via
the document server.
