MACHINE INFORMATION

25 April 1997 INTRODUCTION

1. INTRODUCTION

The SP3 base engine contains an interface for the SP3 multi-function
controller. The SP3 multi-function controller adds printer and/or scanner
functions.

In addition to the original copy functions of the SP3 base engine, the SP3 can
print image files received from a host computer, and supports SCSI scanning
(optional). The printer supports the PCL5E and optional PostScript printer
languages. Host printer data can be received at the standard parallel, serial,
or optional network port.

An IDE hard disk drive is standard, to provide storage for temporary print
data as well as other functions.

The controller board has 2 DRAM SIMM slots for additional RAM modules.
Up to 64 MB (32MB x 2) of memory can be installed to improve the printer
performance. The base memory is 8 MB, so there is a maximum total of 72
MB.

Overall

Information

Images can be printed at 300, 400, or 600 dpi. The engine supports a
maximum print speed of 40 pages per minute when printing at 300 dpi, which
is the same speed as copying at 400 dpi.

The hard disk is used to spool, and print input data, and store image data as
required for reverse order output or duplexing.

1.4.1 Partitioning

The hard disk partitioning is used as follows:

Permanent Partition: not used

•

Temporary Partition: used for storage of data that is not maintained

•

across power cycles. This partition contains files for the input spooler and
reverse order printing. This partition is reformatted during system
initialization following a printer reset or power cycle, or by an explicit
command received from the SP3 operation panel.
PostScript Partition: used exclusively by the PostScript option. This

•

separate partition allows PostScript to format its disk as required by the
PostScript command programs without affecting the other disk partitions.

FEATURES 25 April 1997

2. FEATURES

2.1 MULTIFUNCTION OPERATION

2.1.1 Share Mode
Overview

Share mode allows copying, printing, and scanning. If there is no printing or
scanning function being performed, the control panel shows the copier
screen and copying functions are allowed.

Entering Printer Mode

The SP3 control panel may transition to the printer screen in two different
ways.

When input from any of the external I/O ports,(parallel, serial, or network

•

interface) is processed and requires the usage of engine resources, the
printer controller requests control of the print engine.
The user may also initiate the display of the printer control panel by

•

pressing the scanner/printer button. If a copy job is in progress the job will
complete before the control panel changes to the printer screen.

Note that even if the control panel shows the copier screen the printer may
be online. The online/off-line status is indicated by the online LED. Whenever
the printer is online it is capable of receiving incoming print data.

2-10

25 April 1997 FEATURES

When the Printer/Scanner key is pushed or the SCU receives an MF
(multifunction) mode transition request from the SP3 Controller, the SP3 will
shift to MF mode and the SCU will display the MF mode screen. However, it
is impossible to shift to MF mode in the following cases.

During a copying operation
In Interrupt Copy mode
During an error condition at the engine side (SC occurrence, jam, etc.)
While setting an SP (Service Program) or UP (Utility Program) mode

Otherwise, the On Line LED blinks when the SP3 Controller is initializing, and
this LED is turned on when the SP3 Controller becomes available.

FEATURES 25 April 1997

Return to Copy Mode

When the printer screen is displayed on the control panel, the user can return
to the copier functions by pressing the Copy button. At this time, the printer
controller will finish the current job that it is working on, scanner or printer job,
and then release the engine resources. Any remaining jobs in the printer
controller pipeline will remain queued until the printer controller regains
control.

Interrupt Copying

If while printing, an interrupt copy request is made, the data flow out of the
interpreter to the video is halted at a suitable page boundary.

When the current page being printed in the engine has exited to the
appropriate output bin, the copy job can proceed. When the copy job is
finished, the interpreter will continue where it left off and finish the print job.

Host data input continues to be spooled during copying. When the interrupt
copy is complete the print job will resume printing from where it left off.

If a duplex job is in progress when an interrupt copy takes place, the pages in
the duplex bin will remain there. The interrupt copy job is not allowed to use
the duplexer.

Scanner Jobs

In order to initiate a scanning job, the control panel must already be
displaying the printer screen. The scanner soft button is pressed to request a
scanner job. When the current print job is complete, the scanner job may be
initiated from the host PC.
While the scanner mode screen is displayed the printer is off-line.

2-12

25 April 1997 FEATURES

2.1.2 Printer Only Mode

In this mode, only printing is allowed. If the user presses the copy or interrupt
copy key, an error beep will sound. Scanning functionality is not available.

2.1.3 Scanner Only Mode

In this mode, only scanning is allowed. If the copy or interrupt copy button is
pressed, an error beep will sound. During scanner only mode, the printer is
offline.

2.1.4 Printer Priority Mode

This mode works the same as multifunction mode except that interrupt
copying is not allowed.

Descriptions

2-13

FEATURES 25 April 1997

2.2 PCL5E PRINTING

The SP3 controller provides PCL5E compatibility conforming to the PCL5
Technical Reference Manual.

The ROM resident font data contains PCL5E font data, consisting of 45
scaleable typefaces in 14 typeface families (35 Intellifont format and 10
TrueType format fonts). In addition, 6 bit mapped typefaces in the Line
Printer typeface family are available. The bitmapped fonts are created for 300
dpi, and scaled for 600 dpi as necessary.

The Transparent Font Manager (TFM) is compatible with HP downloadable
and scaleable soft-font formats.

2.3 POSTSCRIPT PRINTING

The SP3 controller supports Adobe PostScript Level II, as defined in the
PostScript Language Reference Manual and the PostScript Language
Reference Manual Supplement for Version 2015.

Downloading of PostScript Type 1 fonts is supported. PostScript includes a
rasterizer for TrueType fonts which allow TrueType fonts to be downloaded
as soft fonts. No resident TrueType fonts are supported. (Note: PostScript
TrueType fonts and PCL5E TrueType fonts are accessible by the respective
personalities).

2-14

25 April 1997 FEATURES

2.4 SCANNER OPERATION

Memory Requirements

The host PC determines the amount of free memory available for scanning at
any time. The amount of free memory sets a limit on the maximum number of
pixels which may be imaged. Since the entire image is scanned into memory
before any data is sent to the host, there must be enough available memory
to contain the entire image. For example, an 8
contains 8.5 x 11 x 400 x 400 = 14,960,000 pixels. In black and white mode,
8 pixels are stored per byte, requiring 14,960,000/8 = 1,870,000 bytes of free
memory. In grayscale mode, one pixel is stored per byte, thus 8 times as
much free memory is required.

The amount of free memory available for scanning depends on the printer
mode. The maximum amount of memory is available for scanning when the
printer is in the scanning only mode. In all other modes, memory is shared
with the printer languages. The amount of free memory will vary greatly when
memory is shared as memory is allocated and deal located for fonts and the
internal working storage requirements of the active languages.

function mode or printer priority mode at a job boundary. Scanning is initiated
by an operation at the control panel. Once the scanner session has been
initiated at the control panel, everything is driven from the SCSI host via SCSI
commands.

Ending a Scanner Session

Upon completion of a scanner operation, the user terminates scanner mode
using the control panel. If the SP3 controller is in multifunction mode or
printer priority mode, and no SCSI commands are received within a time-out
period, SCSI mode will be exited automatically.

A649D502.wmf

The SP3 controller supports "auto-switching" between all active inputs.
At any instant in time, there is a current active port, and all of the other ports

are in a blocked condition. When the current active port stops receiving data
from a host computer, the port time-out becomes active.

If more data is not received from the host for the user specified port time-out,
the machine monitors all ports, and any port with data can become active on
a "first come first serve" basis.

Each port can have a different port time-out values, selectable by the user.

2.6 AUTOMATIC PRINTER LANGUAGE SWITCHING

The SP3 controller can change the page description language (PCL or
PostScript) for the print job automatically, if the personality setting is "Auto".

2.6.1 Printer Language S witching Methods

The following methods are shown in order of priority in which the SP3
controller performs printer language switching.

1. Using the particular PJL ENTER command

2. Using intelligent personality selection

3. Default for the system (PCL)

2.6.2 PJL Entry Commands

PJL functions as a job control language where commands are inserted in the
print stream. One of its capabilities is to provide explicit selection of a
particular personality.

2.6.3 Intelligent Personality Selection

When performing intelligent personality selection, the SP3 controller may
scan up to 512 bytes of the printer-stream data to make its decision. If the
SP3 controller cannot decide after scanning 512 bytes, then it resorts to the
next highest priority selection method available.
