Section 1
About the EFP9800 Printer

The EFP9800 printer is a fast, quiet, reliable, and very compact multiple­function printer. It prints receipts and a journal, validates and prints checks,
and prints on a variety of single- or multiple-part slips. An additional option is
the Magnetic Ink Character Recognition (MICR) check reader with parsing
which reads account numbers on checks for easy verification.

The industry-standard RS-232C and IEEE 1284 bi-directional parallel
communication interfaces allow the EFP9800 to be connected to any host
computer. The EFP9800 provides the following emulations: Epson 370/375
printers (included in the EFP9800 ESC/POS commands), Ithaca Peripherals
Proprinter emulation, NCR 5021 printer, (Serial Interface Only) and the EF4270
printer. These emulations provide easy integration into applications written for
these printers and emulations.

3255 4073–002 1–1

About the EFP9800 Printer

Note: A Running Change acoustic noise reduction enhancement was

released for the EFP9840 and EFP9841 serial interface units. This
Running Change incorporates a new solenoid clamp assembly and a
revised controller PCBA to further reduce acoustical noise. The
change was incorporated into factory production starting at serial
number 5108 67054. All EFP9840 and EFP9841 units with serial
numbers 5108 67054 and above will have the acoustic enhancements.

The new solenoid assembly has a bumper added to the plunger to

reduce noise. This new solenoid requires a new lower case and
therefore cannot be installed in The EFP9840 and EFP9841 units
below serial number 5108 67054.

The revised PCBA incorporates a modified print head pin firing

scheme. The PCBA fires the pins in staggered pairs to reduce
acoustical noise. This new PCBA is fully backward compatible with
previous style EFP9800’s.

Maintaining and Cleaning the Printer

There is no customer maintenance required for the EFP9800 printer. However,
you may occasionally clean the cabinet as needed to remove dust and finger
marks. Use any household cleaner designed for plastics, but test it first on a
small, unseen area. The cabinet finish and materials are durable and are
resistant to cleaning solutions, lubricants, fuels, cooking oils, and ultraviolet
light.

If the receipt paper bucket is dirty, wipe it with a clean, damp cloth.

Caution

Do not spray or try to clean the printhead or the inside of the printer with any
kind of cleaner as this may damage the printhead or the electronics.

Operating the Printer

Changing Receipt Paper

Note: Use these instructions if you are printing receipts only. If you are

printing both receipts and a journal (record of transactions), or a
journal only, see “Changing Receipt/Journal Paper” later in this
section.

Note: All EFP9800 Series printers have a receipt journal take up spool

assembly factory installed that is not always required or utilized by
the client.

If the receipt take up assembly is not used, an occasional noise will

occur as the take up roller assembly rotates.

The receipt take up spool has a spring-loaded roller that allows easy

loading. However, if the receipt take up capability is not being used
the spring loaded roller shaft will spring upwards and hit the printer
top cover once per revolution.

In cases where the receipt take up assembly is not being used it can

be secured in a closed position so that it will not hit the top cover
during printing to eliminate the occasional nuisance noise.

A small piece of tape or a rubber band can be used to keep the take up

roller assembly in a closed position at all times.

Verifying Checks

Follow this procedure to verify checks on printers with the MICR check reader
option. The printer’s Magnetic Ink Character Reader (MICR) check reader reads
the magnetic ink characters on the check in order for the host computer to
verify that the check is good.

Note: Verify the check before you validate it. For more information, see

“Validating Slips and Checks” later in this section.

2–8 3255 4073–002

Operating the Printer

1. Insert the check from the front, face up, with the MICR characters to the
right, as shown.

2. Slide the check toward the back of the printer along the right side until it
covers both sensors.

The Slip In LED turns on when both sensors are covered, indicating that the
check is inserted properly. The printer reads the magnetic characters on the
check.

Note: Do not hold or keep the check from moving during the MICR

check reader transaction or the check numbers will not be
read accurately.

3. Follow any instructions from the host computer.

Once the check has been verified, the printer may then print the date,
payee, and amount on the check, depending on the host computer software.

For more information, see “Printing on Slips and Checks” on the next page.

4. Remove the check after it has been fed all the way back out.

5. Follow the instructions from the host computer to finish the transaction, if
provided.

6. To validate the check, follow the procedures in “Validating Slips and
Checks” later in this section.

3255 4073–002 2–9

Operating the Printer

Printing on Slips and Checks

There are several types of transactions for which you may print on a slip or
check. These include some credit card transactions, merchandise return forms,
electronic funds transfers and check printing (printing the date, payee, and
amount on the check).

The EFP9800 can print on slips and forms up to five-parts thick (the receipt is
included as one or two of the parts depending if it is one-ply or two-ply). For
more information on the types of slips and forms you can use, see “Ordering
Paper and Supplies” in section 1.

Note: Do not use this procedure for validation or check verification. See

“Verifying Checks” on the previous page, and “Validating Slips and
Checks” on the next page.

1. Insert the slip/check from the front, placing it on the slip table first, with
the side to be printed face up.

2. See the illustration for an example of how to insert a check. Use the same
procedure for any type of slip.

You may also insert the slip/check from the side. In this case, insert the

slip/check at an angle with the side to be printed facing you, and then rotate
it until it is vertical. See the illustration.

3. Slide the slip/check to the right until it lines up against the wall.

Replacing the Printhead

The impact printhead is extremely reliable. However, it may need to be changed
depending on the use of the printer. Printhead replacement is required if it is
tearing or fraying the ribbon, or if some dots print lighter than others. Call a
service representative for printhead replacement.

Adjusting the Paper Low Sensor

Before adjusting the paper low sensor, make sure the power is off. Place the
printer on a level surface or adjust it while mounted on the host computer. Do
not apply pressure to the top of the printer while making adjustments.

3255 4073–002 2–15

Operating the Printer

Procedure

The paper low sensor lights the paper low/out LED when the paper roll is
almost empty.

You can raise or lower the paper low sensor assembly to change the amount of
paper left on the roll when the sensor lights the paper low/out LED. Raise the
assembly by turning the screw counterclockwise to signal paper low earlier
(more paper left on the roll). Lower the assembly by turning the screw
clockwise to signal paper low later (less paper left on the roll).

You need a Phillips head screwdriver to make this adjustment.

1. Open the rear cover.

2. Turn the screw on the paper low assembly to raise or lower the sensor,
changing the amount of paper that will be left on the roll when the sensor
activates the paper status LED.

3. See the table for more information.

4. Close the cover.

Section 3
Diagnostics and Print Tests

The following diagnostic tests are available for the EFP9800:

• Level 0 Diagnostics: Performed during the startup cycle and each time the

printer is reset.

• Level 1 Diagnostics: Performed using DIP switches or the Paper Feed

button.

• Diagnostic Print Tests.

Level 0 Diagnostics

The printer automatically performs Level 0 diagnostics each time it is turned on.
Level 0 diagnostics include the following:

• All motors and solenoids are turned off.

• Microprocessor timing is checked.

• Firmware ROM is tested.

• On board and external RAM are checked.

• If this test succeeds, the green Online LED flashes once.

• If this test fails, Level 0 diagnostics stop. The printer becomes inactive: the

printhead does not home, the red Paper Status and the green Slip In LED’s
turn on, and the printer is unable to communicate with the host computer.

• Printhead is homed. If this action fails, a fault condition occurs.

• Status of all sensors is checked and status bytes are updated.

If this is the first time that the printer is turned on, or if a new NVRAM has been
installed, the default values for the printer functions and tests are loaded into
NVRAM during Level 0 diagnostics. To change the printer functions and tests,
use Level 1 diagnostics. For more information, see “Level 1 Diagnostics” on the
next page.

3255 4073–002 3–1

Diagnostics and Print Tests

If both the red Paper Status and the green Slip In LED’s are steadily illuminated,
it is an indication that the NVRAM has failed.

When the last step of the Level 0 diagnostics is complete, the Paper Feed button
is enabled and the printer is ready for normal operation.

If the printer does not complete Level 0 diagnostics, the LED’s flash to indicate
the problem. See “Getting Service” in section 4.

Level 1 Diagnostics

Level 1 diagnostics are selected using the DIP switches or the Paper Feed
button. During Level 1 diagnostics, the printer is not communicating with the
host computer. The diagnostics are described in this order:

• Switch Entry Mode

• Internal Switch Pack Values in NVRAM

• Flash Download Mode

• Data Scope Mode

• Verifying Read of MICR Characters

• Checking MICR Noise Level

• Selecting the Font for the MICR Check Reader

• Diagnostic Print Tests

Information About DIP Switch Settings

To run Level 1 diagnostics, use the DIP switches to change settings. See the
following illustration for the location of the switches on the EFP9800 printer.
Keep these points in mind when using the DIP switches:

To turn a DIP switch on, push it down. To turn a DIP switch off, push it up.
The settings can only be changed when the printer is about to enter Level 1

diagnostics. Switch 1 must be set to On, and switch 2 set to Off.
The default options are set at the factory and are stored in non-volatile memory

or NVRAM (also called EEROM). After the settings have been changed and
stored in NVRAM, the DIP switches must be set back to the normal settings for
the printer to operate. For a list of normal settings, see “Setting Switches” in
section 5.

3–2 3255 4073–002

Diagnostics and Print Tests

After changing the DIP switch settings, cycle the printer by pressing the Reset
button off and then on again. The green Online LED flashes when the printer
cycles.

Caution

If you are changing the switch settings for a function or test, be sure you
choose the correct settings to avoid accidentally changing the settings for
another function or test. If you do accidentally change the settings, use the
switch settings shown in the tables throughout this section to change those
settings back, or return to the normal settings. For a list of normal settings,
see “Setting Switches” in section 5. If you need assistance, contact a service
representative. For more information, see “Getting Service” in section 4.

Switch Entry Mode

Use Switch Entry mode to set the printer emulation or the internal switch pack
values in NVRAM.

Note: For an alternate method to set the emulation and switch settings, see

“Section 10: Flash Download Commands.”

The EFP9800 printer can emulate the following printers and emulations:

• Epson ESC/POS (370/5) printer

Note: This emulation is included in the EFP9800 ESC/POS

commands.

• Ithaca Peripherals Proprinter emulation

• NCR 5021 printer (EFP984x Serial Interface Units Only)

• EF4270 printer

Note: The EFP9800 FLASHADMIN software utility can also be used for

emulation and internal DIP switch configuration. This utility is
included in the EPF9800-SW1 style package.

The EFP9800 printer has one set of DIP switches, while some of the emulated
printers have two or more sets. You can enter values for the extra switch packs
into “internal switch packs” stored in NVRAM.

Note: Secure the roller assembly in a closed position to eliminate the

nuisance noise from occurring when the take-up assembly is not
being used.

All procedures completed in Switch Entry mode include two steps:

• First, tell the printer what you want to do—either choose an emulation or

choose an internal switch pack value. (For example, choose the Ithaca
Peripherals Proprinter emulation or internal switch pack 2.)

• Second, enter the value for the operation—either the specific printer

emulation or the values for the internal switch pack.

Both steps are completed by setting the DIP switches. During the first step, the
Slip In LED is on. During the second step, the Slip In LED is off.

Once you’ve finished setting options in Switch Entry mode, turn off the printer
and set the DIP switches back to the settings for the appropriate
communication protocol. The options you set in Switch Entry mode are stored
in “internal switch packs” in NVRAM until you change them.

Flash Download Mode

This section describes the protocol used to download firmware to the printer
from an application through the communication connector. Requests are
provided to query the state of the firmware and to check the CRC of a given
flash sector. All downloading must be done with 8 bit communications.

Note: An alternate method of putting the printer into flash download mode

is to send the Put the Printer in Flash Download Mode command (1B
5B 7D) during normal operation. See “Section 10: Flash Download
Commands” for more information.

Caution

The DIP switches are set at the factory to predetermined settings. Change the
settings carefully to avoid changing other functions. Run the Diagnostic Print
Tests to see what emulation the printer is set for. For more information, see
“Diagnostic Print Tests” later in this section.

Note: The EFP9800 FLASHLOAD software utility can also be used for

downloading firmware to the unit. This utility is included in the
EFP9800-SW1 style package.

Before putting the printer into the flash download mode, install the program
that implements the download protocol onto the host computer (or any IBM­compatible computer that can be connected to the printer for diagnostic
purposes). This program is available from Unisys. Contact your Unisys sales
representative for more information.

1. Turn the printer off.

2. Turn the printer to the back to access the DIP switches and write down the
current switch settings.

3. To put the printer into flash download mode, set the DIP switches to the
appropriate settings for the interface you are using.

Data Scope Mode

Data scope mode is used to check communication between the printer and the
host computer. When in data scope mode, the printer is configured for normal
operations and receives all communication from the host computer. Instead of
performing the commands however, the printer prints them in hexadecimal
format on the receipt in the order they are received. For example, “1” prints as
hexadecimal 31, “A” prints as hexadecimal 41, and so on.

Enter Data Scope Mode

Caution

The DIP switches are set at the factory to predetermined settings. Change the
settings carefully to avoid changing other functions. Run the Diagnostic Print
Tests to see if the Data Scope mode is on or off. For more information, see

Verifying Read of MICR Characters

This test reads the characters on a check and prints a hexadecimal dump of the
characters on the receipt. It is also referred to as the MICR Read and Print Loop
test. This is a continuous test.

Note: The MICR check reader feature has been factory adjusted for a

normal operating environment with a host computer. However,
additional devices, such as CRT monitors or large metal surfaces
near the printer, can affect the printer’s magnetic field, causing
intermittent reading errors when the MICR check reader is in
operation.

This condition can be easily diagnosed by checking the noise level of the MICR
check reader. See the next section, “Checking MICR Noise Level” for more
information.

Caution

The DIP switches are set at the factory to predetermined settings. Change the
settings carefully to avoid changing other functions.

5. Insert the check into the printer from the front, face up, with the MICR
characters to the right.

See “Verifying Checks” in “Section 2: Operating the Printer” for more

information about inserting checks to be read by the MICR check reader.

Note: Do not hold or keep the check from moving during the MICR check

reader transaction or the check numbers will not be read accurately.

6. Slide the check toward the back of the printer along the right side until it
covers both sensors.

The green Slip In LED turns on continuously when both sensors are

covered, indicating that the check is inserted properly. The printer reads
the magnetic characters on the check and feeds the check back out.

The printer prints the decoded data on the receipt, and then prepares the

printer to receive another check to continue the test.

7. To stop the test, wait until the printer completes a cycle and is waiting until
a new check is inserted.

8. Turn the printer off and reset the DIP switches to what they were when you
started.

For normal operation settings, see “Switch Settings” in section 5.

Checking MICR Noise Level

This test checks the extraneous signals picked up by the MICR check reader
and prints a reading indicating the relative level of the noise. If the noise level is
printed as a letter lower than F (A-E), then the MICR check reader will generally
read the MICR characters without problems. However, if the letter printed is the
letter F or above, there may be problems when reading the MICR characters,
and you may need to call a service representative.

Note: The MICR check reader feature has been factory adjusted for a

normal operating environment with a host computer. However,
additional devices, such as CRT monitors or large metal surfaces
near the printer, can affect the printer’s magnetic field, causing
intermittent reading errors when the MICR check reader is in
operation.

When Something Goes Wrong

The EFP9800 printer is a simple, generally trouble-free printer, but from time to
time minor problems may occur. For example, the power supply may be
interrupted or the paper may jam.

For some problems, the printer communicates the information to the host
computer and relies on the application to indicate the problem.

You’ll be able to fix most problems easily. For some problems, you will need to
contact a Unisys-authorized service representative. Any time a problem persists,
contact a service representative.

• Printer does not cycle or stop when required.

• Illegible characters or light print.

• Paper does not feed.

• Platen does not open or close.

• Printer does not communicate

• MICR check reader not reading characters on checks

Note: The MICR check reader feature has been factory adjusted for a

normal operating environment with a host computer. However,
additional devices, such as CRT monitors or large metal surfaces
near the printer, can affect the printer’s magnetic field, causing
intermittent reading errors when the MICR check reader is in
operation.

This condition can be easily diagnosed by checking the noise level of the MICR
check reader. See “Checking MICR Noise Level” in section 3 for more
information.

Getting Service

For serious problems, such as the printer not printing or not communicating
with the host computer, contact a Unisys-authorized service representative to
arrange a service call.

Section 5
Communication

In order for a receipt or slip to be printed, a program must be in place that
translates the data from the host computer into a language the printer can
understand. This program must tell the printer exactly how to print each
character. This section describes how to create such a program or modify an
existing one.

Interfaces

In order for the printer to communicate with the host computer, a
communication link must be set up. The EFP9800 supports the following
industry standard interfaces:

• RS-232C interface

• 1EEE 1284 parallel interface

Sending Commands

Once the communication link is established, commands can be sent to the
printer. This section describes how to send commands to the printer using DOS
and BASIC. This section does not take into account the necessary protocol— it
is meant as a general introduction to how the printer functions.

Using DOS to Send Commands

One way of getting commands to the printer is to send them directly from DOS.
For example, the command:

COPY CON: COM1:

means that the hexadecimal code corresponding to any key that is pressed is
sent to the RS-232C communication port COM1 when the COPY mode is exited.
If the printer is connected to COM1 and the communications modes match,
then the data will go to the printer.

3255 4073–002 5–1

Communication

Exit the COPY mode by typing:

CTRL Z

[Enter]

Once the computer knows to direct data from any print command to the proper
port, commands can be sent from any software program.

Using BASIC to Send Commands

In BASIC, printer commands are sent as a string of characters preceded by the
PRINT command. For example,

PRINT#1, CHR$(&H0A)

(where #1 is the file number of a communication line opened by the OPEN

“COM1:”

sends the hexadecimal number 0A to the printer, which causes the printer to
print the contents of its print buffer. Previously sent commands tell the printer
exactly how this data should appear on the paper. For example,

command. For more information, see your BASIC documentation.)

PRINT#1, CHR$(&H1b)+CHR$(&H21)+CHR$(&H021); “ABC”;
CHR$(&H0A)

sends the hexadecimal numbers 12 41 42 43 0A to the printer. This causes the
printer to set itself to double-wide mode, load the print buffer with “ABC” (41 42

43), and finally, to print (0A). The communication link the BASIC program
sends must be matched to that of the printer.

RS-232C Interface

The following sections explain the interface protocols and connectors for the
RS-232C interface. For information on the parallel interface and connectors, see
“Parallel Interface” later in this section.

RS-232C Interface Protocols

The RS-232C interface has a protocol associated with it that the host computer
must understand and adhere to.

Only when the interface parameters are matched and the proper protocol is
used will the host computer and the printer be able to communicate.

The RS-232C interface uses either XON/XOFF or DTR/DSR protocol.

5–2 3255 4073–002

Communication

• For XON/XOFF, a particular character is sent back and forth between the

host computer and the printer to regulate the communication.

• For DTR/DSR, changes in the DTR/DSR signal coordinate the information

flow.

The RS-232C version of the EFP9800 offers the standard options which are
selected with the DIP switches. For more information on these settings, see
“Setting Switches” later in this section.

XON/XOFF Protocol

The XON/XOFF characters coordinate the information transfer between the
printer and the host computer. The printer sends an XON character when it is
ready to receive data and it sends an XOFF character when it cannot accept any
more data. The software on the host computer must monitor the
communication link as shown in the following flowchart in order to send data
at appropriate times.

3255 4073–002 5–3

Communication

DTR/DSR Protocol

The DTR signal is used to control data transmission to the printer. It is driven
low when the printer is ready to receive data and driven high when it cannot
accept any more data. Data is transmitted from the printer after it confirms that
the DSR signal is low.

RS-232C Interface Connectors

This section describes the pin settings for the RS-232C connectors and interface
parameters. The RS-232C parameters are selected by setting the DIP switches
on the PC board. For more information, see “Setting Switches” later in this
section. The RS-232C parameters must match those of the host computer.

RS-232C Communication Connector Pin Assignments

The following illustrations show the RS-232C communication connector and pin
assignments. The connector is a 9-pin male D-shell connector and is located at
the rear of the printer.

Parallel Interface

The parallel interface is an industry standard IEEE 1284 bi-directional interface.
It communicates in the following modes: compatibility, nibble, and byte.

The following sections explain the interface protocols and connectors for the
parallel interface. For information on the RS-232C interface protocols and
connectors, see “RS-232C Interface” earlier in this section.

Parallel Interface Connectors

This section describes the pin settings for the parallel connectors and interface
parameters. The parallel parameters are selected by setting the DIP switches on
the PC board. For more information, see “Setting Switches” later in this section.
The parallel parameters must match those of the host computer.

Parallel Communication Connector Pin Assignments

The following illustrations show the parallel communication connector and pin
assignments. The connector is designated as a IEEE 1284-A receptacle and is
commonly know as a D-subminiature 25 pin connector. It is located at the rear
of the printer.

Setting Switches

The DIP switches are located at the rear of the printer as shown in the
illustration. They are used to set the communication parameters as outlined in
the table. These parameters must match those of the host computer in order for
the host computer and the printer to communicate.

Note: The switches are also used for setting other functions and tests. Be

careful not to accidentally change the settings for the other functions.
For more information, see “Level 1 Diagnostics” in section 3.

Use a straightened paper clip or other pointed object to set the switches.

1. Turn the printer to the back to access the DIP switches.

2. Set the switches to the settings you want, using the options in the tables
below.
There is one table for RS-232C interface settings and one for parallel
interface settings.

Caution

Do not set switch 1 to On. Setting switch 1 to On puts the printer in Level 1
diagnostics (setup mode) where other functions and tests can be changed. Set
switch 1 to Off when setting switches for the interface settings. This puts the
printer in the Online mode so it can communicate with the host computer.
