The printer can be connected to the host via a serial or parallel cable.

3.1.3 Interface Cables

An interface cable is necessary to connect the printer to the host. The
interface between the printer and the host will be either a serial RS-232C
or parallel cable. Cable configurations for serial (RS-232C) interfaces
are shown below, (contact your reseller for part numbers and ordering
information).

3.1.2 Interface Connection

The printer can also be connected to the host with a parallel connection.

4.5.2 Auto Media Calibration Procedure

The ‘Auto Media Calibration Procedure’ allows the operator to automatically
obtain the optimum (TOF Low and TOF Delta) values for a particular media.
These values are useful for media that continues to have troubles after Media
Sensor has been manually calibrated (usually preprinted media). This operation
feeds 10 inches of media using the current Media Sensor Calibration setting and
calculates the TOF Delta and TOF Low values to be used. Upon completion the
printer will exit back to ‘Calibration Mode’ flashing the PAUSED light if
successful or the FAULT light if not successful.

Note: Before calibrating, be sure the media sensor is set for the appropriate

media type, see section 4.4.2, also be sure the printhead is latched down
and the cover is closed.

To perform the Auto Media Calibration complete the following steps:

the button until the PAUSED light turns off then release.

3. Next press the button, (the printer will now calibrate to the
media)

4. The PAUSED light will flash 5 times to indicate a successful

calibration. The FAULT light will flash 3 times to indicate an
unsuccessful calibration.

Note: If you wish to discard your changes and revert back to the previous

calibration simply turn off the printer before Step 5.

5.1 Cleaning the Printhead

Warning: Turn ‘off’ the printer and unplug the unit from the outlet

before cleaning the printhead.

1. Turn ‘off’ the printer and open the cover.

2. Push the printhead latch back toward the back of the printer and
raise the printhead carrier assembly.

3. Using a Cotton Swab dipped in isopropyl alcohol, rub the Cotton
Swab along the Printhead.

5.2 Fine Printhead Adjustment

A fine printhead adjustment set screw is located on top of the printhead
carrier assembly that can be used for adjusting print quality. This
adjustment is set at the factory and should not need further adjusting;
however, with different types and thickness of media some adjustment
may be necessary.

To adjust the printhead, turn the Set Screw until optimum print quality is
obtained, (some trial and error may be necessary). Do not over tighten
the Set Screw.

Note: It is not necessary to remove the Ribbon Handler Assembly, (if

equipped). An access hole in the assembly is provided
adjustments.

mn-4203

5.3 Ribbon Width Adjustment

The adjustable ribbon handler feature allows adjustment to the ribbon
supply hub that provides optimum tension when using different widths
of media or ribbon.

1. Turn ‘off’ the printer.

2. Hold the Hub and rotate the Ribbon Tension Adjustment Knob to
meet your media/ribbon widths based on the table below. Ensure
that the Ribbon Tension Adjustment Knob is turned fully to the
clockwise or counter-clockwise position, the knob will no longer
turn once it is in the proper position, do not force or over turn.

5.4 Media Width Adjustment

The thumbwheel on the side of the printhead carrier assembly allows the
printhead to be adjusted for various sizes of media. The numbers on the
thumbwheel serve only as a reference point and do not correspond with a
particular media width. To adjust for narrow media move the
Thumbwheel to the left (frontward), for wide media move it to the right
(rearward).

1. Load media into the printer.

2. Print a label, if it is light on the right-hand side then move the
Thumbwheel to the right (rearward), (see example below).

Light print on the right side of the
test label indicates that the
Thumbwheel should be adjusted
to the right (rearward).

Note: If the media begins tracking to the right while printing the

Thumbwheel should be adjusted to the left (forward)

cables from the back
of the printhead.

Replacement:

1. Connect the printhead cable to the new printhead.

2. Position the printhead on the printhead carrier assembly and tighten
the printhead screw.

3. Ensure that the printhead cable is not pinched and that the Printhead
is clean.

mn-4203

5.6 Darkness Adjustment

The Darkness Adjustment (located on the rear of the printer), allows the
operator to adjust the ‘print darkness’ on the printed ticket. Turning the
Darkness Adjustment clockwise will make the print darker, turning it
counterclockwise will lighten the print.

Note: Large increases the ‘Darkness Adjustment’ can shorten

printhead life. If you need to increase the ‘Darkness’ level large
amounts, try instead increasing the Heat value and/or slowing
the Print Speed through your software or DPL commands first.

5.7 Resetting to the Factory Defaults

With the printer off, press and hold the F1, F2, and F3 buttons while
turning the printer on. Continue to hold the buttons down until the
PAUSED light turns off. The printer will now be set to the 'Factory
Defaults'. See Section 4.4.1 for a listing of the factory defaults.

40

mn-4203

5.8 Downloading Firmware and Fonts

The Printer stores the printer’s Boot Loader, Operating Program, and Font
firmware in flash memory located on the main PCB. This allows an operator to
update the printer’s firmware through the printer’s parallel port. These updates
will include bug fixes and/or new features. The following procedure can be used
to update the Boot Loader, Operating Program, and Font firmware by
substituting the correct filenames.

Updating Instructions:

1. Identifying the New Firmware - Firmware program updates and new
features are available from our web site. Simply download the desired
version on to your computer’s hard drive or a floppy disk.

2. Placing Printer into Download Mode – Press and hold the Pause and
Cancel buttons simultaneously while powering up the printer. All three
indicators on the printer should be on.

3. Downloading – The printer is now ready to accept new printer firmware.
Using the DOS copy command enter:

copy filename.dlf lpt1/b

After the download starts the Paused and Fault lights will turn off. Once the
download is complete the printer will turn on the Paused light (indicating a
successful download) or the Fault light (indicating an unsuccessful download).
If the download fails (i.e. Fault light on) simply send the file again, if the
download continues to fail here are some possible causes:

1. Invalid or corrupted file being downloaded.

Make sure the file you are downloading to the printer is correct and
applicable for your printer model.

2. Communications errors.

Check the cable connections on the host computer and the printer. Be sure
to use a quality-shielded cable.

3. The Printer could not successfully write to or erase the flash memory.

Flash chips or main PCB defective. Try again and if problem persists call
for service.

Unacceptable print quality:

• Dirty printhead. Clean the printhead, (see Chapter 5).

• The printhead temperature is too high. Use the software

control to adjust the Heat Setting, Print Speed, or adjust the
darkness adjustment located on the back of the printer.

• The incorrect ribbon/paper combination is being used, check
the ribbon type being used.

The Printer does not print or prints several labels at once:

• The labels are incorrectly loaded, see the loading
instructions on the inside cover of the printer, or Chapter 3.

• Faulty Printhead, replace, (see Chapter 5) or call for service.

• The media is not calibrated, (see Chapter 4)

• The media sensor or media sensor circuitry may be

defective, call for service.

The ribbon does not advance

(The printer advances paper but ribbon does not advance).

• The ribbon is installed incorrectly. Open the printhead and
make sure that the ink side faces the paper. With most
ribbon this can be verified by rubbing paper against the
ribbon, the ink should smudge the paper. With label stock
use the sticky side of a label, the ink will stick to the label.

• A bad ribbon/paper combination is resulting in an
insufficient amount of friction between paper and ribbon.
Ensure that the correct type of ribbon is being used.

mn-4203

43

Skips every other label

(Print quality is good but skips every other label).

• The label is formatted too close to the top edge of the form.
Leave white space equal to 8-dot rows at the top of the label,
approximately .02" (.5mm).

• The media is not calibrated, (see Chapter 4)

• The media sensor or media sensor circuitry may be

defective, call for service.

Unable to print in rotation 4

• The characters are formatted outside the dimensions of the
label. Check that the row/column values provide enough
room for the height of the characters or bar code to be
printed.

Prints light on the right side of the label

• The media width adjustment thumbwheel is set for a
narrower media width than the actual media being used,
(see Chapter 5).

• The printhead is not properly aligned, call for service.

• The printhead is not locked down.

Printer fails to turn on

• A fuse may be blown, call for service.

• Faulty AC cord, replace

• A bad power switch may exist on the printer, call for

service.

• A faulty AC wall outlet.

44

mn-4203

Label advances 1-2 inches before a fault indication

• The ribbon is installed incorrectly. Make sure that the dull
side (side with ink) is facing the paper.

• A bad ribbon/paper combination is resulting in an
insufficient amount of friction between paper and ribbon.

Label advances 16 inches before a fault indication

Tracking Problems

Ensure that the correct type of ribbon is being used.

• The media is not loaded properly, see Chapter 5. When
loading media be certain that the media hub and media guide
is against the media and that gaps or marks in the labels are
in line with the media sensor.

• The media sensor or media sensor circuitry may be
defective, call for service.

• The media is not loaded properly, see Chapter 5. When
loading media be certain that the media hub and media guide
is against the media.

• The media width adjustment thumbwheel is not set properly,

Embedded Fonts and Barcodes

All character fonts and barcodes available with the printer are described
in this section. Each font and barcode has a name associated with it for
use in programming. Human-readable fonts have numeric names while
barcode fonts have alpha names.

Fonts

Fonts 0 through 8 use the slash zero (Ø) conventions for distinguishing
between the zero and the alphabetic O. The slash can be removed with
the label-formatting command Z. These fonts are non-proportional
(monospaced); all of the characters take up the same amount of space
when printed.

The Triumvirate font number 9 is a proportional font; each character will
take up a different amount of space when printed.
