INTRODUCTION

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 minute respectively at 600 dpi.

1. Printer Controller

The printer controller handles the following functions:

•Printer host interface

•Printing functions

•Interface and control of controller options (Hard disk, PostScript kit, Network interface board and SDRAM)

2.Hard Disk (option)

This stores additional soft fonts and macros (both PCL and PostScript fonts).

B335D500.WMF

The above block diagram shows the major components of the printer controller.

The main features of the controller are as follows.

1. CPU

A Motorola Power PC 740 processor is used. A 66-MHz oscillator is used as the clock source for both this CPU and the coprocessor.

The processor has a bus clock of 66 MHz and an internal clock of 266 MHz.

2. Co-processor (Peerless QP1910)

This performs the following functions:

•ROM control

•I/O control

•DRAM control

•Printer video interface

•Printer communication interface

•IEEE 1284 compliant bi-directional parallel port interface

•Interrupt control

2) Flash ROM DIMM (4 MB for the PostScript option)

This ROM DIMM includes the PostScript code and PostScript font data.

3) SDRAM DIMM (32 MB and an option slot)

This SDRAM DIMM provides page memory and work area.

4. NVRAM (8 KB)

The NVRAM contains the system parameters, printer settings, job record data, and error record data.

5. Network Interface Board Interface

This controls the optional network interface board provided to support the network operations.

6. Hard Disk Drive Interface (Enhanced IDE: 6 GB)

The HDD interface is provided to support storage of fonts and macros downloaded from a PC.

B335D503.WMF

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.

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.

Detailed Descriptions

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/81/2”x11” (in the case of 8 pages)

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

8th page

• A4 lengthwise/81/2”x11” or smaller (in the case of 14 pages)

1st page – 3rd page – 5th page – 2nd page – 7th page – 4th page – 9th page –

6th page – 11th page – 8th page – 13th page – 10th page – 12th page – 14th page

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
