Installing/De-installing Modular I/O Card

Your laser printer has a modular input/output (MIO) interface slot on the rear panel. If you have purchased Anzac's internally twinaxed version of this printer, this slot will be filled with the Anzac twinax MIO card. If you are purchasing a Anzac twinax MIO card for installation in a regular PC-type laser printer, follow these installation instructions. For more information about MIO cards, contact Anzac. When you install/de-install the Anzac card, follow these steps:

1. Turn off the printer and unplug the power cord from the wall socket.


Be sure to turn off the power to the printer before installing or removing the Anzac card. Failure to do so may result in damage to your printer or card.


2. Remove the two screws and cover plate from the printer's MIO interface slot.

3. Unpack the Anzac card and hold it on its edge.  

 


Do not touch the card surface. If static electricity collects, it may damage the card.

 

4. Insert the card until it is securely seated.

5. Secure the Anzac card with the two captive screws on the card

6. Retain the cover plate and two screws removed in step 2 in case you want to remove the Anzac card later.

Connecting the Printer to Your

IBM AS/400, System /36, or /38

If you have the twinax port installed on your printer, you may hook this printer in-line to your IBM system via twinaxial cable. A "smart" T-connector has been supplied with this printer to auto-terminate your line if this is the last device on that line or allow cable-through if there are more devices on the line. For an explanation of the lights and parts of the interface card, see "Twinax Communication Problems".


The printer must not be directly attached to the IBM system without the "smart" T-connector. If the T-connector is not used, communication problems may arise.

Since the interface selection mode has been factory set to "AUTO", simply connect the interface cable to the printer.Connect the printer to your system as follows:

1. Make sure that the printer is turned off.


Always turn off the printer when connecting and disconnecting a cable.

2. Simply attach the long end of the T-connector to the printer at the small BNC-type plug, then connect up your twinax line to the double end of the T-connector.


The small end of the BNC-type plug has a recessed half-moon with a male pin and a female half-moon socket opposite it. The printer's twinax port will have a complimentary configuration. When plugging the T-connector to the printer, make sure the male half-moon fits into the female half-moon and vice-versa.

3. Twist the BNC-type cylinder down onto interface plug to secure it. Make sure all barrel plugs are tight on system cables.

4. Set the Device Address Switch on the interface card to match your IBM system's Device Address (Switch Setting). Valid addresses are 0 through 6.

When using the twinax port through the Anzac MIO card, your laser printer's emulation must be set for an HP LaserJet emulation. Some laser printers allow several different emulations through the control panel such as Epson FX or IBM PPR besides HP LaserJet. If your emulation is set to something other than HP LaserJet, you may experience garbage characters or unexpected results.

To get the most out of your laser printer on your PC through the parallel or serial ports, you need to install the printer driver for this printer on your PC and select it through your application if possible (For example, if using Windows 3.1, go to your Program Manager and click on your Print Manager. Click on Options in the toolbar and click on Printer Setup. Click on the Installed Printers selection that most closely matches the model of the printer you are using. If there is no match, then click on Add and find the correct driver on the list and install the Windows driver disk. Contact Microsoft or the printer manufacturer if you do not have the correct driver disk. Then in your Windows application, click on Printer Setup or Print and select the newly installed Printer description.).

Twinax Communication Problems

SCS Type Printers

If your printer is having trouble communicating with your IBM AS/400, System /36, or /38, the printer's front panel display may not register an error. If an error does register or if the printer is not on-line, then corrective user intervention must be taken before the printer can communicate properly. See the following troubleshooting list to correct the error. If no error is present on the display, then the LED light(s) on the back of the printer next to the twinax connector will help diagnose the problem.

If your printer is an SCS type printer, you will have four small LED lights with the following functions:

 

(In order from top to bottom)

Printer Fault; (RED): This LED will flash continuously if the interface detects any fault at the printer which will prevent it from printing. Common faults include printer is in an off-line or deselected state on control panel, printer is out of paper, or the cover is open.

System Communication (SYNC); (GREEN): This LED will flash continuously when the printer is attached properly to an active IBM System Address. If it is not flashing, then the interface is not detecting a signal on this cable. If this LED flashes for a few seconds, disappears and returns, then recheck your device address to verify that there are no conflicts with other devices on the port. There may also be a problem with the actual cable or the T-connector.

Parity Error; (YELLOW): This LED will flash if some of the data received was garbled. Each block of data is checked for integrity when it is received from your IBM system and if there are cabling or addressing problems, this LED will flash. The printer may continue to perform because Anzac interfaces have high recovery capabilities.

Power (GREEN): This LED stays on continuously if the interface is receiving power from the printer. If this is not lit, check that the printer is turned on, the AC power cord is secure, and the wall plug or surge protector is supplying proper voltage.

Twinax Communication Problems

IPDS Type Printers

If your printer is an IPDS type printer, then you will have a single LED with the following functions:

Green Flashing: Interface has power and is ready to receive data (printer has SYNC). If the LED is flashing constantly, then it is communicating properly with the IBM system. If the (IPDS) flash is slow or intermittent, then there may be a line problem. Try another cable and/or port.

Green Solid: Interface has power and is ready to receive data but is not communicating with the IBM system. Verify your device address and try another cable and/or port.

Red Flashing: Interface has power and is communicating properly with the IBM system (SYNC), but is not ready to receive data. Common faults include printer is in an off-line or deselected state on control panel, printer is out of paper, or the cover is open.

Red Solid: Interface has power, but is neither communicating with the system nor ready to receive data. Common faults causing the light to turn red include printer is in an off-line or deselected state on control panel, printer is out of paper, or the cover is open. Common faults causing the light to be solid include bad cabling or incorrect device address.

No Light: Interface does not have power -- check that the printer is turned on, the AC power cord is secure, and the wall plug or surge protector is supplying proper voltage.

Device Address Seven Test

To enter the Device 7 test, turn the printer off, change the device switch on the "backpanel" to address 7, and turn the printer on again. The Device 7 test should be used when installing printers for the first time to verify that all connections are intact following the shipping process. Successful completion of a Device 7 test indicates that the MIO interface is receiving power, and that the board is communicating with the rest of the printer. It DOES NOT mean that the printer is receiving data from the computer system(s).


In more recent Hewlett-Packard printer revisions, the Address 7 Self-Test does not work on powerup. To obtain the Address 7 Test information, follow the directions in the next section describing steps to put the printer in Voyuer Mode, which will yield the same results.

A successful Device 7 self test printout indicates the following:

Firmware Revision Number And Checksum.

The firmware revision number identifies the type of code running the MIO board. The checksum identifies this code based on numeric characteristics. As a current standard, the code has been write protected, otherwise the printer's checksum would change whenever the printer is used.

Config Bytes

The configuration byte settings are used to make changes to the printer's setup. Due to the constant changes in functionality, access to these configuration bytes is generally limited to Programming Support.

Page Count And Line Count

This option is enabled or disabled based on whether or not the MIO's firmware has been write-protected.

The System Emulation

This is the emulation which the minicomputer system uses to identify the printer. The system emulation commonly used is 3812/5219.

Virtual Printer Type And Protocol

This identifies the printer language used by the printer engine. The commonly used printer type is the HP LaserJet which uses PCL protocol. Advanced programmers using Anzac Advanced Printer Functions may want to access such protocols in order to utilize special printer functions.

The Character Set

A description of the printer character set required by the Firmware Revision.

Available Fonts According To GFID

Fonts listed according to their GFID numbers vary according to the amount stored inside the printer. Repetition of font styles is common and often intentional, because many fonts have more than one GFID number assigned.

VOYEUR MODE

The MIO includes a self diagnostic tool called Voyeur mode. It is similar to the Hex Dump utility provided by many printers. However, Voyeur mode allows the user to analyze the data being sent to the printer from the host system, rather than the data that has been converted by the MIO board. Voyeur Mode prints the exact IBM system commands being used, as well as their Hexadecimal equivalents.

Retrieving a Voyeur Mode Test can be the first step in diagnosing a problem unit. If possible, obtaining a Voyeur along with an equivalent Hex Dump test will provide Programming Support the clues to determine whether a problem is hardware or firmware related. Whereas entering Hex Dump mode is a different process from printer to printer, Voyeur Dump Mode's activation process is common across the Pinnacle line and requires the following steps:

  1. Power the printer off, wait a few seconds, then power back on.
  2. Increment the Device Address switch from the original address, pause for a few seconds on "7" (which is an invalid address on your IBM system), then continue past "0" back to the original device address. For example, if your current address is "3", push the button under the window so that the number changes ("4", "5," "6," "7," pause, then continue on, "8," "9," "0," "1," "2," "3," stop).
  3. The system operator must now send the problem file or print job which needs to be analyzed to the printer as you would normally submit the job for printing.
  4. The printer will begin printing out the job that was sent in a special format which identifies all page formatting codes and data.

To exit Voyeur mode, make sure the device switch setting is still set to its original value. Turn the printer off, wait a few seconds, then power on.

For further documentation, refer to the Anzac/Apollo "Good Book of Twinax."
