Figure 3-1 Control panel layout with example of self test screen after a test run. 



After entering the test mode (see next section), the display will appear divided in three fields: 



- status line 

- scrolling window 

- test list 



(first line) 

(four central lines) 

(last line) 



The status line shows the status of the self-test and the result of the last test session (if any). 
The status can have the following values: 

- (none) Waiting for test selection / start. No tests executed so far. 

- Passed Last test passed; waiting for test selection / start. 

- Failed (xxx) Last test sequence failed with xxx error code; 

waiting for test selection / start. 

- Running Test sequence running. 

The elapsed time of the test session is shown on the right. It increases during test execution and it is frozen 
after the test session ends. 



If status is "Running" but the elapsed time STOPS, this means that a fatal error has happened and the test 
session must be considered FAILED. This usually happens for defective JetDirect cards.

The four central lines are used as a scrolling window to display information (revision numbers, errors, etc) 
and to inform the user on the current state of test execution. 

When the test session finishes, using the arrow keys on the right of the LCD it is possible to scroll this 
window up and down. 

Last line contains the list of available tests. The selected ones have an asterisk (*) on the left. 



3. 1 ENTERING THE TEST MODE (SHIFT + ALT + D) 

The Extended Self Test (EST) built in the product is able to detect with high level of confidence which 
hardware part is failing, providing a quick tool to troubleshoot. 

Follow these steps to ENTER TEST MODE: 

1 . Connect Control Panel and ADF, connect power cord, unlock the scanner, power on the unit. 

2. Wait until the control panel LCD is completely darkened. 

3. As soon as the LCD starts clearing (curtains open), press simultaneously the keys 
SHIFT +ALT +D 

and release them only when the curtains are completely opened. 

4. After approximately 30 second the LCD will display the EST window with keys usage directions. 
Press any key to continue. At this point the self test revision is displayed. 

5. Select tests to be executed. 

To select/deselect a test, press its number using the numeric keypad (1 to 5). 
6. 



If the ADF test is selected, load at least 7 paper sheets in the ADF. 

If the Scanner test is selected and the ADF test IS NOT selected, DO NOT load any pages in the ADF 



(The Scanner test will fail if the ADF has still pages on it. If the ADF test has been selected also, it will be executed first, and it will scan all 
pages in the ADF, so that when the Scanner test starts the ADF will be empty. If the ADF test IS NOT selected, you have to clear the ADF by 
yourself to avoid Scanner test failure) 

7. Start the test session pressing the green key. 

The execution order is from left to right. It has been set in this way to reduce waiting time in case of failure 
and to guarantee to correct sequence when testing both ADF and scanner. 



In case of failure the test STOPS, the error code is displayed and on the last line a question is 
displayed: "Running test failed. Continue? (y/n)" 



It is possible to continue the test session answering 'y' or to stop it pressing 'n'. The session will be 
considered failed anyway. 

After a completed test session (passed or failed), it is possible to change the test selections and to restart the 
testing with the green key. 

The following picture shows an example of the log displayed in the scrolling window after a full test session. 

Most useful information: 

• Each diagnostic shows its revision at the beginning of execution. 

• Firmware revisions for PC A, scanner and hard disk are shown in the related tests. 

• Hard disk model is shown. 

• Partition table is listed. For each partition, displayed information are: type, starting sector, number of 
sectors. 

• For ADF, scanner and hard disk tests, the longer ones, some progress information are displayed.

3.4.1 Control Panel Self Test Hardware Requirements 

The CP cable must be plugged into the connector of the network box and the HP 9100C must be ready (boot 
phase completed). 

[The CP could be connected also to some external source of power, such as a lab power supply. In this case, to execute the self test 
the unit needs only to be powered on (VCC +5V, GND 5V, VCC +24V, GND 24V) and its reset line should be pulled up to +5V. If 
the data lines and the interface need to be tested, a loop-back connector must be added between the scanner box and the control panel 
connector. The purpose of this connector is to connect the CPRDY line to the CPCLK line and the CP2AS line to the AS2CP line 
coming from the control panel, leaving only the power lines going from the scanner box to the control panel, in a way to provide the 
needed power source. The reset line should be pulled up. This process is not documented for the time being, ! 



3.4.2 CP Self Test description 

1- Make sure the HP 9100C is running (boot phase completed) 

2- Disconnect the CP cable from the rear of the HP 9100C 

3- Re-connect the CP cable to power on again the CP 

4- After the screen has become all black and the curtains open, press the keys ALT + SHIFT + 3 and keep 
them pressed until the curtains are completely opened. Then release the keys. 

The screen becomes again completely black for 4 seconds and the leds will flash. In this phase the user can 
check the LCD pixels deterioration or white spots. 

Then the screen opens again and the following message is displayed:

RAM0=80 means the battery of the clock is low and the clock stopped. 



[If a loop-back connector is provided between the CPCLK line and the CPRDY, and between CP2AS and AS2CP, also the data 

interface will be tested. 

The test will send out data and check what has just received. If the clock line is properly connected, the LCD zone drawn in the 

upper left part of the screen will start getting black and then again white, cycling from top to bottom. 

If some errors are detected in the receiving line AS2CP, the display will signal it changing some pixels in the LCD area.] 

Below the LCD area there are some 'o' . They represent the keys of the CP. 

If a key is pressed, the corresponding 'o' in the LCD will be changed to 'x' permanently.

The user should press all the keys one at a time and change all the 'o' to 'x'. 

Only the 'shift' key will return from 'x' to 'o' when released, because there are two shift keys to be tested. 

The contrast level of the LCD and accordingly the PWM value can be changed by pressing the keys: 

[ALT + A ] or [ALT + ▼ ] on the right side of the LCD. 

The backlit module can be switched on and off by pressing ALT + GO (green button) or ALT + ABORT

4 Inside the Self Test 

The two software tools referred to in this chapter are the Digital Sender Test Software (DSTS) and the 
Extended Self Test. 

The former is a Windows NT application that interfaces to the scanner through the synchronous serial port 
and that uploads and runs diagnostics. It is used only in the manufacturing environment 

The latter is a test kernel internal to the scanner that can be run without external hardware and that executes 
diagnostic programs stored in the hard disk. 



4.1 DIMM Module 

The Dual In line Memory Module (8MB currently) is mounted on the PCA and its test is performed when 
testing the whole board. Refer to the PCA testing for more information. 



4.2 PCA 

This is the main board located in the NB nearby the Power Supply. 

4.2.1 Test description 

The PCA diagnostic software (PCATST) includes tests that check some basic functionality of the ASICs and 
their connections. All life components (uP NEC VR4300, Styx, Juliet, SDRAM and Flash memory) will not 
be deeply tested, because in case of defect the whole test session could not be executed. 

The implemented tests are: 

• ASICs test 

- Styx registers test 

- Styx DMA transactions 

- Juliet registers test 

- Juliet mailboxes read/write test 

- Romeo registers test 

• On board RAM test 

• DIMM test 

• Pipeline test (Juliet-Romeo-DRAM connection) 

4.3 Hard disk drive 

4.3.1 Types of failures 

Hard disk failures belong to two classes: 

Drives not operating correctly 
Drives that cannot access all the data. 

The first kind of failure is more evident, because the disk simply doesn't respond to commands, is not ready, 
can't reset and so on. Just trying to access it is possible to detect a problem in this class. 

The second class is subtler and contains all the problems related to the disk surface or to the mechanical 
ability to reach each area of the disk itself. 



HP P/NC131 1-90009- Rev. C 18 



HP Property E£l £ 



EWLETT* 
PACKARD 



Disks are however able to recover problems of the second type when they are restricted to very limited 
areas. There are in fact some spare tracks that are used when defective ones are found. Sometimes it is also 
possible to recover failures related to the surface (ECC errors) simply writing on the area that has the 
problem. 

4.3.2 Hard disk partitioning

4.4 Jet Direct card 

This is the card removable from the rear of the HP 9100C, without opening up the Network Box. 

4.4.1 Types of failures 

JetDirect testing is composed by two main blocks: 

1- Functional test that verifies the card hardware functionality 

2- Conformity test that ensures the right model and firmware revision is being used. 



HP P/NC131 1-90009- Rev. C 19 



HP Property HESSE" 



4.4.2 JetDirect self-test 

The functional test is performed using the JetDirect self-test (BIST+extended self-test; refer to EIO 

specification). It can be executed just once after power-on and stores results in the Status Register and Error 

Register of the EIO memory space. 

To run the test, a handshaking session must be performed acting on some registers in the network card. A 

timeout can be managed to detect "dead" cards that don't respond. 

Duration is approximately 7 seconds. 

Main tests run by self-test are: 

• Midplane controller register test 

• DRAM test 

• EPROMCRCtest 

• Memory-to-memory copy/checksum test 

• PROM checksum test 

• FLASH station address test and, for Ethernet models 

• Frontplane registers test 

• Ethernet controller tests. 

Only fatal errors are notified from JetDirect to peripheral (PC A), thus to the display on the CP. 



4.5 Scanner engine and ADF 

4.5.1 Scanner engine test 

It verifies the ability of the engine to receive commands and checks some functionality related to electronics 
and mechanics. No optics tests are performed at all in this phase. 

The scanner diagnostic verifies: 

• Internal self- test status. 

• Interface to PCA. 

• Ability to reset and to get to home position. 

• Lamp functionality (On/Off). 

• Ability to execute commands and to reply to inquiries (SCL). 

• Image acquisitions with different settings. 

4.5.2 ADF test 

The ADF test checks the following ADF functionality: 

• Internal ADF status. 

• Cover lid sensor (must be closed). 

• Paper presence sensor. 

• Ability to feed with different settings. 

• Loading speed with the fastest scanning mode (15 pages/minute). 

The sequence of tests is as follows:

4.6 Boot phase 

Each time The HP 9100C is powered on, the boot code performs some very brief tests, the initialization of 
the hardware and then checks which execution mode is requested. There are some specific events at the 
beginning of the boot phase that can trigger the execution of manufacturing test or software upgrade. This 
feature is hidden to the customer. 

The picture below describes the boot phase of the HP 9100C, with the outlined pattern showing what 
happens with no actions at the CP during the boot phase.

6 RESTORING THE HP 91 00C AFTER INTERVENTION 
6. 1 In General 

Whenever any of the service part(s) is replaced, the EST must be launched with all test steps included, to 
verify that the unit has been correctly re-assembled. 

However, when the CP or the ADF are replaced, there is no need for the EST to be launched completely, but 
only the CP or ADF step can be performed. 

Remember that the CP has its own built-in self test which is not activated entering the EST mode, but as it is 
described in sec. 2.4. 



6.2 Special Cases 

When replacing the HDD, the JetDirect Card, the main PCA, the unit will loose some or all configuration 
parameters, and it will be no longer capable to operate in the customer's environment. It is thus necessary to 
restore those values. 

The matrix summarizes the lost functionality after any replacements:

After entering the Mandatory parameters, you can exit the configuration menu and e-mail to any internet 
address. 

For all the other functionality, please remember the customer has to re-configure them using the 
Administrative Software (JetAdmin and ABM). Please refer to the Administrative Manual for further details 
on the HP 9100C configuration. 



6.2.2 If the JetDirect Card has been replaced 

There are two possibilities: 

1- The customer uses DHCP (dynamic IP assignment). 
The card will get the new address automatically. 



No action required. 



The customer uses manual IP configuration - Action required. 

At the boot, the machine will show the configuration menu and the IP address will have to be entered. 

This is the only missing parameters needed for operating.

6.2.3 Conformity test {SHIFT + ALT + DUPLEX) 

Simply entering in this mode, it is possible to read all configuration parameters. 

It is then possible to verify that the JetDirect model is correct and its internal firmware has the approved 

revision number. 

JetDirect FW Rev must be G.07.03 or greater to work with the HP 9100C. Cards used on printers or 
other networked devices may not work because of the FW Rev. 

Information contained in the HP 9100C self test page relatively to JetDirect are (written as they appear on 
the display): 

PARAMETER EXAMPLE 

JetDirect Prd. # J1310A 

JetDirect Firmware revision G.07.03 

MAC address 0060B0438C6B 

IP address 15.156.81.90 

TCP/IP status Ready 

Gateway address 15. 156. 88. 1 1 



JetDirect Timeout 90 

JetDirect ID 3727372720sl2 

6.2.4 If the main PCA has been replaced 

The PCA loads its own FW from the HDD; in case a FW upgrade is occurred (FW2), the previous FW 

version (FW1) is still stored on the HDD until 50 jobs are performed. 

To read which FW is running, enter the Self Test Page by hitting (SHIFT + ALT + DUPLEX), then scroll to 

the last row: 

Running Image #: 1 

The PCA stores the current image #. A new PCA always stores image #1. If the unit has been upgraded, the 
old PCA might store image #2. It might be necessary to switch the new PCA to the image #2 to avoid old 
FW usage. 

To swap FW image: 

1- Shutdown the machine 

2- Turn it off 

3- Turn it on 

4- While the curtains start opening on the display, hit (SHIFT + ALT + Fl) 
(Fl is the leftmost soft key below the LCD display; there are four soft keys) 

5- Release the keys when curtains are fully opened 

The FW image has now swapped. This means if FW1 was running now FW2 is, or vice versa. 

If there is no way to know in advance which image is the newest one, after mounting the new PCA you can 
compare the two FW version by doing the following: 

1- After boot, when the machine is ready, enter the Self Test Page ( SHIFT + ALT + DUPLEX). 

2- Read the FW date and version (very first two rows) 

3- Perform the FW image swap, go through step 1-2 and compare. Use the newest one.

7 DEMONSTRATION 

After completion of the HW intervention and Restore of parameters / functionality, it must be shown to the 
customer that the unit is working, from the pure Hardware perspective. 

Here below, in order of simplicity, the most immediate ways to demo are listed. Then the following 
paragraphs explain in details how to set up the demo and the required tools, when needed.

See related paragraph 



7. 1 Check Jobs 

Provided that the unit is configured to send to any possible destination, right after sending the document it is 
possible to check the job status. 

I - 1 lit the Infor mation Q key 

2- Select Efflll (leftmost Soft key, (JJ) 

3- Verify that the document has been sent 

This function is always available. 



7.2 Send via E-Mail 

Provided that the customer has the compatible environment, when the mandatory minimum configuration 
steps have been performed, the post office IP address has been already configured in the HP 9100C. 

It is then enough to position any document in the ADF and select the e-mail soft-key. Then, after typing the 
correct and most convenient internet e-mail address, the document can be sent. It is possible to follow the 
process right after sending the document with the Q key (see par. 6.1 ). 

If the post office was already used by the HP 9100C before intervention, it is almost impossible that the 
sending fails. 



If the HP 9100C was not used to send messages to the post office before intervention, it is possible that 
post office permissions do not allow "new" IP addresses to connect. In this case the post office 
administrator must include the HP 9100C's IP address in the list recognized addresses for the post 
office. 



7.3 Send Via JetSend 

JetSend is a communication protocol which highly simplifies communication between networked devices. 
The HP 9100C is JetSend enabled; the functionality can be turned on/off entering the configuration screen 
(SHIFT+ALT+GREEN).

If the customer has a JetSend enabled printer, it is enough to select the JetSend soft-key on the CP, then 
enter the IP address of the printer and send a page. 



7.4 Send to PC 

This procedure requires that the customer has already installed the client SW and has defined at least one 

user. 

Normally, the customer would know how to operate. In cases where the HDD has been replaced and no back 

up procedure was followed by the customer prior to intervention, he has to create users again with the 

Address Book Manager (ABM, see User/ Admin Guides). 

If the customer is not familiar with the Send to PC function, nor has ever installed the related SW, it is 
strongly suggested to use one of the other two methods, or call the HP CCC to go trough an Assisted 
Installation of the client SW. 



7.5 Send via LAN FAX 

The LAN FAX feature can only be configured using the administrator's SW, JetAdmin. Only if the customer 
was already using this feature, after restoring the machine it is possible to simply select a FAX destination, 

| (See par 5.2).

8 Error codes 



8. 1 Error Management 

A global error list contains all the error codes that the set of diagnostic programs can produce. Each 
hardware component or subassembly has an error code range wide enough to keep all the possible error 
situations related to it. 

The error codes are in the format XYY, where X is the error prefix (one digit) related to the component and 
YY is the numeric code that describes the error for that component. 

Error prefixes are: 

DSTS related errors (not considered as failures) 

1 PCA errors 

2 HDD errors 

3 JetDirect errors 

4 Scanner / ADF errors 

5 Test process errors (considered as failures because potentially caused by the UUT)
