NAD PRINTER CONTROLLER

(Codes: A850)

30 October 1998 INTRODUCTION

1. OVERALL MACHINE INFORMATION

1.1 INTRODUCTION

The NAD base engine contains an interface for the NAD multi-function controller.
The NAD multi-functi on contr ol ler adds fax and/or printer functions. Pri nt er and fax
functions can operate independently and simultaneously with other functions in the
background, and their output will be interleaved with the copy mode output.

The printer supports the PCL6, and PostScript level 3. PostScript language support
is an optional function.

Host printer data can be received via the standard parallel port or the optional
Network Interface Board (NIB). The parallel port supports bi-directional Command
and Status feed back communication with the host machines.

An optional IDE hard disk drive provides font download, macro download, and
other functions.

Additional DRAM SIMMs can be installed to boost the printer performance.
Images can be rasterized at 300, 400, or 600 dpi in the controller but printed at 400

or 600 dpi. For 300 dpi printing, the 300 dpi data from the controller is simulated in
the base engine by printing the same pixel twice and the same line twice at 600
dpi.

The NAD30S and NAD30 engines can print 35 pages per minute at both 400 and
600 dpi. On the other hand, the NAD40 engine can print 45 pages per minute at
both 400 and 600 dpi.

A850D503.WMF

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

The image data from a PC goes to the buffer in the resident RAM. Then, it goes to
the co-processor. The co-processor selects the printer language automatically,
then the co-processor generates the print data to match the selected printer
language. After generating the print data, the co-processor sends it to the LD unit
through the IPU on the BICU board. At that time, the data is also sent to the hard
disk for multiple printing and sorting, as well as backup in case of paper jams.

2-3

IMAGE DATA PROCESSING 30 October 1998

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 tool or the printer driver.

2.3.1 EDGE SMOOTHING

A850D504.WMF

Usually, binary picture processing generates jagged edge on characters as shown
in the above left illustration. The FCI reduces the edges of characters using edge
smoothing.

Whether or not the object pixel undergoes smoothing depends on the surrounding
image data. Smoothing for the object pixel is done by changing the laser pulse
position.

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 print as gray.

2-4

30 October 1998 FEATURES

2.4 FEATURES

2.4.1 SORTING

If “Collate” is turned on and a multicopy job is printed, the first copy of the job will
be printed directly. At the same time, the image data for the copy job is stored in
the hard disk of the main machine. When the main machine prints the next copy,
the next copy will be printed from the hard disk.

If the finisher is not installed, the rotate sort feature can be used. The image is
rotated by the MSU, in the same way as image rotation for the copier.

2.4.2 DUPLEX PRINTING

Duplex printing is available with all output bin options but not all paper sizes (refer
to the specifications section of the copier manual). If a job specifies duplex but the
paper size to be used is not usable in the duplex unit, the job will be printed
simplex.

Duplex printing is available in two binding methods: Short-edge binding and Long­edge binding.

In short-edge binding, when printing the second side of a page, the image may
require rotation. The image is rotated by the co-processor in the printer controller.

The co-processor corrects the image printing order for duplexing as follows.

•

Larger than A4 lengthwise/LT lengthwise (example 8 pages)

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

2-5

FEATURES 30 October 1998

2.4.3 STAPLING

Stapling is only available when the 3000-sheet finisher or 1000-sheet finisher is
installed.

The finishers have the following stapling positions.

1) Upper left, diagonal

2) Upper right, diagonal

3) Left, two staples

4) Top, two staples

5) Right, two staples

6) Upper left, horizontal

7) Upper right, horizontal

8) Upper left, vertical

9) Upper right, vertical

NOTE:

Depending on the paper orientation, the image may have to be rotated. This image
rotation is done by the co-processor in the printer controller.

There is a limit for the number of sheets which can be stapled by each finisher. If a
job that specifies stapling ha s more than this number of sheets, it will not be
stapled.

With the 1000-sheet finisher, only stapling positions 1) and 2) are available.

2.4.4 PUNCHING

Punching is only available when the punch unit is installed with the 3000-sheet
finisher. The number of holes depends on the type of punching unit. The punching
unit has only one available position, so the relationship between the punching
position and the printed image depends on the paper feeding orientation and
imaging. The punching positions are defined as follows.

1) Left

2) Top

3) Right

2-6

30 October 1998 FEATURES

2.4.5 JAM RECOVERY

If the jam recovery feature is on and a paper jam occurs, the controller will reprint
all pages for which a feed-out indication has not been received from the main
machine. In usual cases, all image data from the controller will be sent to the hard
disk on the main machine, When a jam occurs, the recovery data will be sent from
the hard disk on the main machine.

2.4.6 AUTO TRAY SELECT

When “Auto Select” is selected with the printer driver, th e printer searches for a
tray that contains the specified size of normal plain paper. The search starts from
the LCT, and when a tray that contains the specified size of paper is found, the
printer starts printing and feeds paper from that tray. The search sequence is as
follows.

LCT – 1st tray – 2nd tray – 3rd tray – 4th tray – LCT

Detailed

Descriptions

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

2.4.7 POWER ON SELF DIAGNOSTICS

When the controller is turne d on, it performs a self diagnostic sequence of tests
automatically. If any errors were de tected, an error message will be displayed on
the operation panel.

HARD DISK 30 October 1998

2.5 HARD DISK

Two hard disks are used for the printer functions. One is connected to the printer
controller (Printer HDD). The o ther is in the main machine (Engine HDD).

2.5.1 PRINTER HDD

When the main power switch is turned on after the printer HDD is installed, the
machine asks you to format the hard disk.

If you press the “Yes” button, the machine formats the hard disk. At this time, two
partitions will be made on the ha rd disk. One is for PCL and the other is for
PostScript (fonts and macros only).

If you press the “Ignore” button, the machine determines that there is no optional
printer hard disk.

2.5.2 ENGINE HDD

The hard disk in the main machine is used for both copy and printer functions.
Therefore, the hard disk has three partitions: for copier, printer, and archive files
(one of the copier features). The sizes of the partitions depends on the setting of
“User Tools – 1. System – No.23, Memory Priority”, as shown below.

2.7 PAPER OVERFLOW DETECTION

2.7.1 STANDARD OUTPUT TRAY

[B]

[A]

A850D507.WMF

The standard output tray can stack about 500 sheets. There is a paper limit sensor
[A] to prevent paper overflow.

When the t r ay is full, the paper stack pushes up the feeler [B] then the paper limit
sensor is activated. When the sensor stays activated for a certain time, the
machine determines that the standard tray is full. The machine stops the print job
until the paper limit sensor is deactivated.

2.7.2 BRIDGE UNIT

[A]

A850D508.WMF

The bridge unit has a paper sensor [A] to detect paper on the bridge unit. This is
monitored to ensure that the bridge unit does not contain more than 250 sheets. If
a print job of more than 250 sheets is executed, the machine will print u p to 250
pages, then the print job is stopped. Once the output stack is removed, the printing
job automatically continues.
