1-2 Laser Safety Information CAUTION - Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
Classification and Labeling of Laser Product
According to the Code of Federal Regulations, laser products are classified in Classes I through IV. These classes are assigned according to the amount of laser radiation acces­sible to the operator. The PantherPro Image Recorder is certified as a Class I product. The operator is not exposed to any hazardous laser radiation during operation and mainte­nance.
The laser itself, however, is a Class IIIb laser, and emits laser radiation which is considered hazardous according to the Federal Code of Regulations, section 1040.10. This level of radiation is not accessible to the operator as long as the optics cover of the PantherPro is not removed.
The PantherPro uses a low-power, 5 milliwatts laser diode which only emits visible red light. As with any bright source of optical energy, safety precautions should be applied. One should not stare into the beam or any reflections from shiny sources.
PantherPro Image Recorder
Laser Warning Labels
Figure 1-1 represents the laser warning label. This label is located inside the PantherPro on a protective panel that encloses the laser optics, on the rear panel, and the electronics cover. (See Figure 1-2).
CAUTION - LASER RADIATION WHEN OPEN.

Operator Safety
Operator access to laser radiation is not possible during operation or operator mainte­nance. During operation the protective housing prevents access to all radiation fields. The recorder hinged supply cassette cover may safely be opened for operator maintenance. This maintenance includes removing and installing the photographic media supply and take-up cassettes.
To insure safety during maintenance, redundant interlocks shut off power to the laser diode

assembly (laser diode power up to 5 milliwatts at 670 nanometers could be accessible in the machine interior if the interlocks are defeated). The PantherPro electronics and optics covers should never be removed by the customer.
Servicing Safety
Service procedures include removal of the machine covers to replace or adjust compo­nents. The inner laser assembly and other components may be replaced in the field. The laser output and the focused beam are accessible in the interior.
The supply cassette door includes two magnetic interlock switches which are mounted and connected in series so that if the access door is lifted, both switches open to open the interlock circuit. When the interlock circuit is open, all power is dropped to the current source for the laser diode.
All service procedures will be performed with the main power shut off and with the safety interlock circuit open (no laser diode current).
When performing alignments, carefully follow the procedures documented in the technical manual. DO NOT defeat the safety interlock switches unless specified in the procedure. Also, NEVER override the safety interlock switches if the polygon/motor assembly is not spinning, as this could allow the focused beam to be emitted.

Caution: Direct or indirect reflected eye contact with the laser beam may cause serious eye damage.
Warning: At no time should the unit be left unattended with the interlocks defeated.
The following safety precautions should always be observed:
1. Never operate the unit with the optics cover removed.
2. Laser safety goggles must be worn when making any adjustments to the recorder with the interlocks defeated.
3. Any adjustments that are to be made with the interlocks defeated must be made in a secure area, with only trained personnel present.
4. Do not place screwdrivers or other shiny objects in the path of the laser beam.
5. Remove all jewelry from fingers and wrists before making any alignments.
PantherPro Image Recorder
6. Remember that the laser beam is invisible and can cause permanent damage to the eyes.
1-3 Regulatory Agencies Information
The PantherPro is an approved product designed and manufactured in accordance with UL (Underwriters Laboratories) and CSA (Canadian Standards Association) standards. The product also complies with the requirements in Part 15 of FCC Rules for a Class A comput­ing device.
This equipment complies with the requirements in part 15 of FCC Rules for a Class A computing device. Operation of this equipment in a residential area may cause unaccept­able interference to radio and TV reception requiring the operator to take whatever steps are necessary to correct the interference.
The PantherPro also complies with specific European safety standards; international mod­els are shipped with a label bearing the “CE” mark. This label demonstrates compliance with IEC safety standards. The PantherPro also meets EN55022/VDE Class B emissions standards.
1-4 Electrostatic Discharge - ESD
Static electricity is, simply, electricity that is not moving. It is harmless as long as it remains static. Unfortunately, an electrical charge is unstable and is always looking for an opposite charge to unite with. When a charge moves, it becomes a current, which is often greater than a electronic circuit can handle.
The smallest static charge that can be felt is 3,000 volts; the smallest charge that can be
1-4 November 1994
PrePRESS SOLUTIONS CONFIDENTIAL
Page 10
PantherPro Image Recorder TP 8250
seen is 5,000 volts; and the smallest charge that can be heard is 10,000 volts. Some semi­conductor devices are susceptible to a static charge as little as 10 volts. Electrostatic discharge has become more and more of a hazard as microcircuit compo­nents have become smaller and more sensitive.
ESD Prevention Rules
These are the rules to be learned and followed in order to prevent ESD damage to elec­tronic printed circuit boards and assemblies.
WARNING: Make sure you are NOT grounded when working on equipment that is plugged in and ON.
1. Always use the antistatic portable field service kit when working on electronic parts of
PrePRESS Solution’s products or when handling printed circuit boards.
2. Make sure machine is plugged in a grounded outlet (and switched off) if using the ma-
chine frame as a grounding point.
3. Make sure your wrist strap and antistatic service kit are connected together and con-
nected to ground.
4. When replacing printed circuit boards, remove the old board from the machine before
removing replacement board from the antistatic bag. Then install replacement board and place old board in the antistatic bag.
5. Always transport and store electronic components in an antistatic bag.
6. Use the correct size bag, not too big or not too small.
7. Keep antistatic bags in good condition. Bags with pin holes, rips, tears, or crumpled
bags are less efficient and may provide little or no protection.
8. Do not remove components from bags just to look at them. You can usually see through
the bag to identify the part.
9. Keep spare bags on hand.
10.Always ship back field returns in an antistatic bag. Even defective components should
be stored and transported in antistatic bags so that they are not damaged further.
11.Keep static producing materials such as polyester, plastic, and Styrofoam away from elec-
tronic parts.
12.Don’t pick up boards unless you are grounded or the boards are in antistatic bags. Do
not touch edge connectors on PCB’s, or exposed circuitry. Handle IC’s, and boards by

the edges, and never place components on metal surfaces.
13.Static is present at all times, more so when the humidity is low.
14.Educate customers about static protection, especially the ones who maintain their own equipment.

The recorder components, upon input from the HSCB, generates typographic characters and graphics onto visable red sensitive paper, film or plate material.
The images are formed on the media by a laser beam output which is generated by the video data received from the image controller. The video data is received by the laser amplifier PCB, which then output the data to the laser driver PCB and onto the laser diode. The laser diode generates the visable red laser beam which is dispersed across the imag­ing area by a polygon scanner motor and optical system. The paper is moved across the imaging area by a servo leading motor.

3-2 High Speed Control Board (HSCB)
3-2.1 SCSI MUX Module Overview
The SCSI MUX contains the logic necessary to interface any combination of four RIPS and five page buffers. The SCSI MUX is implemented as five four to one input ports. Each port is designed in a modular fashion. This will allows a reduced cost for an entry level system. It also allows each channel to be added or deleted as needed by the user.
The SCSI Mux buffers contain the interface to the connecting RIPS. The buffers for each input port support SCSI -2 Single Ended Alternative. The connector used is a dual SCSI-2 connector, wired in common so that the SCSI port does not need to be the last device on the bus. The lower connector of each pair is labeled 'SCSI In' and is connected to the front end. The top connector is labeled 'SCSI Out' and is used to daisy chain other devices on the SCSI bus only when the 'SCSI In' connector is already used. SCSI bus termination is achieved through active terminators. This means that the SCSI port will sense if the port is the last on the SCSI bus or in the middle of the chain and terminate if necessary.
3-2.2 SCSI MUX Control Logic
There are four registers used by the control logic: an ID register, a select register, a revi­sion register, and an arbitrate register. Only the select register is read/write. All registers are 16 bits wide. Bits not used are not driven. Byte access is not supported.
PantherPro Image Recorder
3-2.3 SCSI MUXS
The MUXS are implemented using 160 pin gate arrays. The arrays incorporate all of the muxs for five channels and the control logic needed to select the direction of the SCSI data bus, and the signals BSY~ and SEL~.
3-2.4 SCSI MUXTest Path
Testing of the SCSI Mux channels are done by connecting a cable (loopback) from the page buffer 0 disk SCSI connector to the port to be tested.
3-3 CPU and Peripherals Module Overview
3-3.1 Microprocessor
A Motorola 68000 running at 16.67 MHz is utilized to provide processing power for the HSCB.Code is executed out of program storage. Upon request it will relinquish the bus to other bus masters.
3.3.2 Program Storage
An EPROM is provided for program storage. This is a 'by 16' part. The EPROM resides at location 0 and at location 0x200000 at powerup. Once the program code starts executing out of the 0x200000 space, the EPROM will no longer reside at location 0.

3-3.3 DATA Storage
A DRAM storage system is provided for CPU data storage. This provides 2 MB of memory. The DRAM is enabled at location after the EPROM starts executing code out of its upper space. The DRAM consists of 4 1MB x 4 parts. A DRAM controller generates read, write, and refresh cycles to the DRAM. The design supports use of 4 256K x 4 parts, providing 512K of memory.
3-3.4 Nonvolatile RAM
A 2k byte NVRAM is provided. It resides on the upper 8 bits of the 68000 data bus. Its base address is 0xD00000.
3.3-5 Interrupt Controller
The interrupt controller receive interrupts from each page buffer module and from peripher­als. Page buffer modules are capable of generating 3 interrupts; one from the HODT_SIOP, one from the Disk_SIOP and one from the 3210 Compressor/Decomprocessor chip. The Disk_SIOP and the 3210 that is imaging is given priority level 5. A mask register is loaded indicating which page buffer is imaging. All other Page buffer interrupts share inter­rupt level 4. Interrupt vectors are provided for each interrupt level.
3-3.6 DUART/Timer
A 2681 DUART/Timer will be used. This will provide 2 serial channels. They are configured as DCE. The timer is programmable. Interrupts are generated when certain DUART conditions are net or when the timer expires. The DUART resides at address D10020 through D1003F.
3-3.7 Keypad Interface
An interface to a keypad is provided. This interlace provides a means to reset the hardware by monitoring a sequence of keystrokes. The keypad address resides at location D10042
3-3.8 Address DecodeNnecessary address decodes are generated for page buffer mod­ules, SCSI MUX modules, and recorder output module.
3-3.9 Strobe/Dtack Logic
I/O strobes, read and write will be generated for I/O devices. Dtack is generated for I/O devices, memory, and registers.

are enabled upon powerup.
3-3.12 Dead Man Timer
A dead man timer circuit is provided such that if not reset every 2 seconds a hardware reset will occur.
3-3.13 Clock Circuitry
Clocks are generated for the CPU, the page buffer modules and the DUART/Timer. A slow clock will be generated for the dead man timer.
3-4 Page Buffer Module Overview
Each PBM consists of two NCR 53c7000 SCSI input/output processors (SIOPs), one AHA3210 Compression Coprocessor (in future revisions), 512kb of DRAM, a disk drive and the circuitry to control the data movement among them.
3-4.1 Clock Generator
the main clock is derived from a crystal oscillator (33.34 MHz) that is at twice the frequency that the MC68000 will operate. This clock is divided in half and synchronize d to the crystal oscillator with reset. The 16.67 MHz rate is then used to run the 68000, the AHA3210's, and as a reference for the SIOP control Logic. While the SIOPs are clocked at the faster
33.34 MHz rate, internally the run at 16.67 MHz. The control logic must be aware of both rates to properly sequence the slave cycles between the 68000 and the SIOPs.
PantherPro Image Recorder
3-4.2 68000 Bus Arbitration Logic
Each PBM has two SIOPs, which can be bus masters. For a fully configured HSCB (5 PBMs present) there are a maximum of ten devices that may request to become a 68000 bus master. Since only a single device can own the bus at any one time, bus arbitration logic must be implemented to control which requesting device is driving the 68000 bus. The priority is always given to the PBM that is imaging. Any request from any input PBM is granted only if there are none pending from the output PBM. The priorities are as follows:
1. Output PBM
2. Output PBM host SIOP
3. Input PBM disk drive SIOP
4. Input PBM host SIOP
If no output PBM requests are made, the input PBMs are granted the bus in a rotating order.

3-4.3 NCR 53C700 SIOP
The NCR53C700-66 is a high speed SCSI controller with a built-in SCSI SCRIPTS proces­sor to perform SCSI SCRIPTS operations with minimal intervention from the HSCBs 68000. The SIOP must be operated in 80286 mode (16 bits) to accommodate the 68000. Since the 53C700 is an Intel compatible device (Little Endian), byte swapping occurs in the hardware for any access between the 68000 and the SIOP. The data rates supported by this device are 5.0 MB/Sec in asynchronous mode and 10.0 MB/Sec in Synchronous mode. This chip contains a SCSI controller, a 32 byte FIFO, a high performance DMA controller and a 2MIP "SCRIPTS" processor that manages the data transfers to and from the HSCB local memory. There are two independent SCSI channels as part of this submodule. The first SCSI chan­nel will provide an interface to the host system via the SCSI MUX Module. This SIOP is setup to DMA the input data from the host SCSI bus to port A of the 3210. The 3210 Port A is configured for slave mode and will compress data as the SIOP writes to port A of the
3210. The SIOP interrupt signals as the predetermined block size of data has been sent to the compressor port from the host. The second SCSI channel provides an interface to the page buffer disk. The page buffer disk stores compressed data from port B of the 3210. During compression, this second SIOP will read blocks of data from a local DRAM buffer and write it back to the drive. Later, the whole compressed job is read back, decompressed, and imaged.
3-4.4 AHA 3210 Compression Coprocessor
The 3210 is used to compress the data received from the host SIOP for storage on the disk or to decompress the stored job for output to the recorder output module. Initially, the host SIOP is set up in 80286 mode. The SIOP fetches instructions from the 68000 memory by becoming a bus master of the 68000. The 3210 is set up for compres­sion with port A as a slave and port B as a master.
3-5 Recorder Output Module Overview
3-5.1 Dual Port Video Memory
A 256k x 16 Dual port Video Memory operates as a large FIFO buffer. This memory con­sists of field RAM, which contain address generation and refresh/read/write arbitration internally. It is loaded with uncompressed data from a page buffer module, and is output to the Scan Line FIFO. The Dual Port Video Memory must be reset before each image.
3-5.2 Scan Line FIFO
The Scan Line FIFO is 16 bits wide. It provides a full scan line of buffering at the highest resolution. Writes into the FIFO occur as a two-clock (minimum) cycle at the system clock rate which can stifle subsequent writes. Data from the Video FIFO is read one byte at a time or as needed to load the video shift register. The FIFO 'Retransmit' signal is used to repeat scan lines. This requires the hardware to
3-5 November 1994 PrePRESS SOLUTIONS CONFIDENTIAL
Page 25
TP8250
reset the FIFO before each scan line. Upon reset, the Dual Port Video Memory transfers one full scan line into the Scan Line FIFO, and then outputs the scan line in real time to the video shift register. If the scan line is to be repeated, the scan line is retransmitted from the Scan Line FIFO. The process is repeated for the next scan line.
3-5.3 Xcount
An Xcount register and counter contains the number of words per scan line, counting the words transferred into the Scan Line FIFO. When the full number of words is reached, transfers stop with the Scan Line FIFO holding a complete scan line. The Xcount register requires loading once per image.
3-5.4 Margin and Blanking
A programmable margin is provided by the Margin Register. For each scan line, a margin counter is loaded with the margin register contents and counted down to zero. The video is blanked, and reading from the FIFO is inhibited until the this margin is exhausted. Once reading from the FIFO commences, the real video is output till the right edge of the media is reached, and the video is again held blank.
PantherPro Image Recorder
3-5.5 Fill
A fill feature allows blank scan lines to be output without fetching of video data. This allows images to be transmitted to the Panther Pro without the corresponding 'blank' data. The fill feature supports automatic blanking at a granularity of single scan lines.
3-5.6 Video Control
Circuitry will count pixels, load the shift register, and issue reads to the Scan Line FIFO at appropriate times. This circuitry is collectively known as video control.
3-5.7 Test Pattern
Capability to substitute a hardware generated test pattern for normal video is provided. Each square of the test pattern measures 128 pixels square.
3-5.8 Serialization
Video output to the laser amplifier is a serial stream. Bytes of video from the Scan Line FIFO is serialized in a shift register and then turned into a stream of pulses before being output to the Laser Amplifier.
3-5.9 PCLK Synchronizer
A clock phase which best matchs the START pulse selects each scan line and output a new PCLK. This will minimize left edge jitter, keeping it to within a fraction of a pixel.
3-5.10 Intensity Control
A register which drives a D/A converter will set the laser intensity. This is the identical circuit used on the RCB.

3-5.11 Facet Timer
A Facet Timer circuit times the scan line and issue various control signals whose timing is related to the scan line. Examples of such signals are: Sample/Hold, Enhance, Inhibit Bias, Speed hi/lo/ok, End of scan, etc. The decoding of these signals is fixed, and is oriented to a specific exspected polygon rotational rate.
3-5.12 End of Scan interrupt
A maskable interrupt is generated once per scan duing the inactive portion of a scan line.
3-5.13 Polygon Speed control
Polygon Speed Control consists of a 16 bit register and a 16 bit counter. On overflow, the counter is loaded from the register, creating a programmable time base. The output of this circuit is the square wave POLYCLK, which is fed to the polygon drive circuitry and resides on a separate circuit board.
3-5.14 Leading Motor Control
The Leading Motor Control consists of a paper feed register, an adder/accumulator, and a Galil GL1200 motor control IC. The adder/accumulator produces a series of pulses at a rate set by the Paper Feed register. The GL1200 converts this into postion information, compar­ing with encoder inputs. Also the GL1200 outputs velosity information. The position and velocity information are summed with the accelerator information to form the input to the motor drive. A nearly identical circuit is used on the RCB.
3-6 Paper Transport Assembly
(Refer to Figure 3-1 Paper Feed Diagram) The paper transport assembly is used to accurately feed the infrared sensitive media from
the supply cassette through the exposure window and into the take-up cassette. The paper­feed mechanism is a capstan drive roller feed device driven by a servo motor under logic control. The paper transport is capable of feeding 8", 12", or 13.3" media.
The supply cassette is a plastic box with end plates. Inside it contains two margin plates with core spindles which are adjustable for different paper widths. The maximum roll lengths that fit in the supply cassette are 246 feet for paper or film.
The media is drawn out of the supply cassette and across the tensioner & metering rollers. The External Tensioning Modual (ETM) sits on top of the metering roller to regulate accu­racy and scewing of the media transport. The backside of the media is then drawn across the imaging roller where the exposure plane is. The media is pulled by the drive and pres­sure roller, past a power cut-off knife and into a take-up cassette.The knife is a automatic power rotary knife assembled in a carriage which transverses across the paper feed. The knife can also be operated manually. (Refer to figure 3-2, Rotary Knife.)
3-7 November 1994 PrePRESS SOLUTIONS CONFIDENTIAL
Page 27
TP8250
PantherPro Image Recorder
Rotation of the knife is transmitted through an O ring which is mounted axially on the same shaft. The O ring is rotated due to frictional contact with the paper-hold-down bar. The bar is spring-loaded upwards to permit passage of the paper. It is compressed downwards by the O ring holding the paper stationary during the cutting stroke.
After the cutting operation, the knife carriage must be positioned at the extreme end of its stroke (left or right), so it is not pressing down on the hold-down bar; otherwise, paper cannot be advanced and a paper jam will occur.

3-7 Optical System (Refer to figure 3-3, Optical System.) The function of the optical system is to image a series of 0.0006 inch spots in a straight line
across a 13.3 inch maximum flat field. The light for the PantherPro recorder optical system is generated by a visible laser diode
operating at 670 nanometers. The light rays originate on the laser diode, then pass through the laser diode lens contained within the diode assembly. The rays then come to a focus about 1.5 inches beyond this lens. Once past the point of focus, the ray bundle which is formed by the light rays begins to diverge.
This expanding ray bundle then passes through the first cylinder lens. The first cylinder lens causes the vertical diverging beams to re-converge while allowing the horizontal beams to continue their divergence. The function of the first cylinder lens is to focus a this horizontal line of light on the polygon facet. This controls vertical focus on the film plane.
After passing through the first cylinder lens, the bundle is redirected toward the scan lens by the beam steering mirror. The function of the beam steering mirror is only to position the beam correctly into the scan lens.
The bundle enters the scan lens and horizontal divergence is stopped and a 20mm wide horizontal collimated beam is formed. This 20mm beam then strikes the scanning facet of the polygon. It is reflected back through the scan lens at a continuously varying angle. The horizontal beam is now converging toward the image plane. The vertical beam is now expanded slightly.
The bundle next passes through the second cylinder lens. Optically this lens causes the vertically diverging beam to quickly converge to focus on the film plane. Since the horizon­tal beam is already converging due to the effects of the scan lens, the second cylinder lens is responsible for both vertical focus and polygon wobble correction.
The PantherPro optics are non-symetrical meaning the vertical and horizontal axis behave independently of each other.
The X, Y, and Z axis's are defined as follows; Z axis - The line alongn the beam center from the diode to the center of the scanline. X axis - This is the scanline sweep horizontally across the measure. Y axis - This is the beam height from top to bottom. This is the same direction as the
media transport.
The PantherPro was designed to require no field optical adjustments. All spare parts are pre-adjusted and ready to install without adjustment in the field. To ensure repeatability and consistency, all parts are aligned on the same factory fixtures.

Scan Lens
Polygon
Laser Diode / Laser Driver
Laser Diode Lens (not shown) - This lens, which is part of the laser tube, reduces the spreading of the beam by 10 times by focusing the beam to a spot 1.5" beyond the diode. This focal point is exactly at the end of the diode tube.
1st Cylindrical Lens - The 1st cylindrical lens cuts the spreading of the beam down in the vertical or Y axis. The horizontal or X axis direction is not affected by the lens and therefore the beam continues to spread horizontally. This affect focuses the beam on the Y axis on the polygon to ensure wobble correction for the polygon mirrors.

PrePRESS SOLUTIONS CONFIDENTIAL
Page 30
PantherPro Image Recorder TP8250
Beam Steering Mirror - This mirror allows for the adjustment of the beam in the Y axis. The beam must be adjusted to pass through the mask opening on the second cylindrical lens.
Scan Lens - Focuses the lens vertically to a spot on the polygon. Polygon - The polygon contains eight mirror facets which reflects the laser beam onto the
horizotal sweep of data across the media measure. Each mirror facet is one scanline. Second Cylindrical Lens - Focuses the beam to the correct spot size in the Y axis. The lens
also pulls the beam to the center in the Y axis direction which also helps to correct for polygon wobble.
Second Cylindrical Lens Mask - This mask cuts away unwanted reflections of the laser. Imaging Roller - This roller positions the media so that it is in the correct focal distance from
the laser.
3-8 Sensors and Switches
The PantherPro recorder area contains the following detectors and switches: Start of line detector
Paper out switch No cassette switch Safety interlock switches Take-up door open switch Media Jam detector
The start pulse detector pickup is mounted on the left margin area of the second cylinder lens assembly. It detects the laser beam start signal and sends it to the laser amplifier PCB.
The paper-out switch is a mechanical switch located on the media-feed assembly that senses the left edge of the paper. When paper is not detected, the switch closes, the signal is sent to the video interface PCB, and a message is displayed on the operator panel LCD screen of the controller.
The no-cassette switch is a mechanical switch located on the on the side of the take up cassette mounting area that senses the presence of the media take-up cassette. When the cassette is not detected, the switch closes and the signal is sent to the video interface PCB, and a message is displayed on the operator panel LCD screen of the controller.

TP8250
The safety interlock switches are magnetic switches mounted on each side of the main chassis by the paper feed top cover. The switches are designed to open when the door on top of the recorder unit is opened. The signal that goes through the switches is 12 volts, which is used to power the laser diode, so that, when the door is opened, the switches are open and no power is supplied to the laser diode.
The take-up door open switch is located on the take-up door. It is in series with the no cassette switch. Its function is to warn a remote front-end that the take-up door is open and the media will be fogged.
Media jam detection is performed by the servo controller IC on the RCB. The servo control­ler IC senses severe loss of phase lock, and reports it as a media jam.

Section 7 Diagnostics
7-1 Overview
The PantherPro contains ROM resident diagnostics and disk resident diagnostics that can be accessed both onsite and remotely through the debug port. Most of these diagnostics can also be accessed through the keypad.
7-2 PROM Resident Diagnostics
The PROM resident diagnostics consists of three sections;
PROM Monitor - Provides interface to the diagnostics,manages non volatile param
eters, sniffs system configuration, interfaces to utilitiesand boots the main application or other disk based programs. level 1 Diagnostics - Power-up HSCB tests (memory, timers, uarts...) level 2 Diagnostics - PBM/SCSI tests
7-2.1 Level 1 Power-up Test Sequence and Definition
The level1 diagnostics are tests designed to test the hardware that makes up the CPU section of the HSCB. These diagnostics are used to verify the minimum hardware required to have a functioning CPU. Once this hardware has passed the level1 tests the level2 diagnostics may be executed. Beolow is an example of the sucessful completion of level 1 diagnostics.

7-2.2 PROM Monitor
The PROM Monitor provides interface to the diagnostics, manages non volatile parameters, sniffs system configuration, interfaces to utilities and boots the main application or other disk based programs.
After the level 1 test pass, the system will prompt the user to type <CNTRL> U to enter the PROM Monitor. The Monitor prompt is "]". Typing an "H" at the prompt will display the help screen. Most of the available options are either for engineering development or for factory use only. The page buffer programs and level 2 diagnostics are for field use. The help screen is as follows;
A - Autoload from SCSI AI num - Set autoloader target ID to num AS - Autoload from Sun B - breakpoint C - continue D - Diagnostics options Menu DU - Dump 68000 Register Set FD - Display file directory FE [file]- Execute file if given else ‘main_app’ FL [file]- Load file if given else ‘main_app’ FR file - Remove file G [addr] - go H - print this help message N - single step R - reset system and reboot power-on tests RES - reset and restart the monitor V - enable one interrupt X - Debug Flag Editor
PantherPro Image Recorder
Typing a "D" will display the Diagnostics Options Menu (Level 2). Typing "FD" displays the available programs on the Page Buffer Disks. Typing "FE [hscb_diag or ropmdiag] will run the selected diagnostic.
7-2.3 Level 2 Diagnostics
The level2 diagnostics are made up of page buffer module and SCSI tests. These tests will be performed on all installed page buffer modules during power up if the level 2 diagnostics are enabled. During the interactive mode, selected or all diagnostics can be performed on individual page buffer modules. These tests can also be configured to test all installed page buffer modules in this mode.
Typing "D" at the Monitor prompt will display the following menu;

Section 8 Reference/Adjustments
DANGER - Invisible laser radiation when the top cover is open and interlock de­feated. Avoid direct exposure to beam.
CAUTION - Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
NOTE - Maintain all Anti-Static procedures while performing removal/replacement procedures on pc boards.
8-1 Jumpers, LED’s, and Switches Reference
The following details the switch settings, LED’s, and jumpers found on the PC boards.
High Speed Control Board
LED's:
LOCK - Indicates that the polygon driver has locked the polygon speed. This should always be lit when the polygon is spun up.
LO/OK/HI - These three indicate polygon speed is lo, ok, or hi. They are updated every scan line. When the polygon is spun up, OK should be lit.
STOK - Start pulses that are generated when the laser sweeps across the SOL sensor is found by the laser amp PCB either in normal imaging or when switch 3 (PGEN) is closed.
VMWR - Indicates video writes into the dual ported video memory to the scan line FIFO. This LED is not brightly lit.
VMRD - Indicates video reads from the dual port video memory to the scan line FIFO. This LED is not brightly lit.
VID - Indicates actual video data. This LED is lit during the exposed parts of an image (laser on). Note the sample / hold and enhance video activity light is lit dimly during an all white image.

8-1November 1994
Page 67
TP8250
POLY ERR - Indicates a polygon error condition. This happens only during imaging (page enable on); the LED is kept on until the start of the next image. This error is caused by loss of lock or by loss of speed OK, however briefly, during an image.
FIFO MT - Indicates a FIFO empty error condition. This happens only during imaging (page enable on); the LED is kept on until the start of the next image. This error is caused when a video read from the scan line FIFO is attempted and the FIFO is already empty.
WCB Switches:
Switch 1 & 2 - They are used for factory diagnostic testing. They should be in the OFF position.
Switch 4 - Quad switch sw4 is comprised of 4 switches, switch 1 through 4, left to right. These switches should be left in the open position for normal operation.
Switch 1 - PGEN - Sets page enable, allowing start pulses to be found. Provided the polygon speed is OK, the laser will do the normal functions of sample / hold and enhance, finding start pulses. If the light path is interrupted (SOL blocked) the en hance laser power is kept on for about 93% of the time, searching in vain for a start pulse. This provides a simple means of checking or adjusting the enhance laser power level.
PantherPro Image Recorder
Switch 2 - SHOLD - Forces Sample/ Hold on for laser calibration. This switch closes the sample / hold loop by forcing video ' 1's' pixels and sample / hold on, continuously. This provides a simple means of checking or adjusting the 'imaging' laser power level.
Switch 3 - POLYSW - Spins up Polygon independent of software, uses purely hardware generated signals.
Switch 4 - POLYTYPE - Tells software the polygon type (on=Lincoln, off=Copal). Not imple­mented at this time.
Jumpers:
Front-end Connect Jumpers JP1 - FES0 Connect Ground - Install jumper if SCSI port/cable connected to J10 does not
have a ground on Pin 40. JP2 - FES0 Connect Ground - Install jumper if SCSI port/cable connected to J11 does not
have a ground on pin 15. JP3 - FES1 Connect Ground - Install jumper if SCSI port/cableconnected to J8 does not

ground connected on pin 40. JP8 - FES3 Connect Ground - Install jumper if SCSI port/cable connected to J5 does not
have a ground connected on pin 15.
WCB EPROM Jumpers:
JP9 - 10 EPROM Address Jumpers - Default etch connects pin 1 and 2 together. This jumper will not change. JP9 connects address bit 18 to EPROM and JP10 connects bit 19 to EPROM.
WCB LCD Jumpers:
JP33 - LCD Inverter Power - Default etch pins 1 and 2. 1 and 2 provide +5Vdc to LCD inverter.
JP34 - LCD frame Ground Connection - Default etch provides logic ground to LCD Frame ground.
JP35 - LCD Character Size - Default etch pins 2 and 3. 1 and 2 provides 6 by 8 character size, and pins 2 and 3 provides 8 by 8 character size.
Page buffer Module Jumpers:
JP11 - JP26 On HSCB (Page Buffer Module 0) are connected by default in etch to bypass the 3210 compression chip.
JP27 - JP32 On HSCB (Page Buffer Module 0) 1 and 2 jumped to bypass the 3210 com­pression chip.
JP110 - JP125 On Page Buffer Modules (1 - 4) are connected by default in etch to bypass the 3210 compression chip.

Section 9 Parts Listing
explanatory
General
This illustrated Parts Catalog has been prepared to assist in identification of parts which may require replacement as a result of wear, damage or loss.
Parts Groups
A group shows a main physical sub­assembly. Each group comprises an itemized illustration and a list of the parts shown in the illustration.
Key
Every part or assembly listed has a key number which corresponds to the illus­tration. The key number for an assembly will appear in the illustration in a circle close to the appropriate parts.
A suffix (A to Z, with the exception of I and O) may be added to the key num­ber, where necessary, for the following reasons:
1. The key indicates parts which are
identical as far as installation and function are concerned, but which differ in part number, e.g. motors for different voltages (also relays, sole­noids, etc.)
Part Number
The full part number must always be used when ordering parts.
Description
This column includes the name of the parts and possibly one or more of the following:
1. up to machine no. xxxx This part is only used in machines up to the stated serial number
2. from machine no. xxxx This part can only be used in ma­chines with quoted serial number or a higher one.
All parts which require permanent rivet­ing, welding, or assembly in jigs or fixtures will be furnished assembled.
When the description is indented it is an indication of the assembly level of the part.
Quantity
The column quantity (Qty) shows the quantity of each part as included in the next larger assembly.
2. For non-interchangeable parts, the new style part is identified by a new line with the old key number (with suffix), followed by the new part number, description, and quantity.
