Adjustments and Maintenance

2.1.1 Cleaning the Printhead

NEVER use a sharp object on the Printhead; damage can result.

CAUTION

If print quality declines (symptoms can include non-compliant bar codes, print dropouts, streaks on the labels), the typical cause is debris build-up on the printhead. Furthermore, if the build-up is not removed it may lead to element failure, greatly reducing the life of the printhead.

Faulty Label:

Instead of consistent patterns, streaks in the direction of print indicate a dirty or faulty printhead.

According to the media, ribbon, and printing parameters used, different methods are recommended for cleaning the printhead. In all cases, perform the following preliminary operations before cleaning the printhead:

Preliminary Cleaning Steps:

1) Stop printing. Raise the cover, unlock the Printhead Latch and raise the Printhead Assembly.

Allow the printhead to cool.

2) Remove media and ribbon from the printer.

Proceed according to your cleaning requirements.

2.2 Media Sensor Calibration

This printer can use many different media compositions, configurations and colors. In addition to adjusting the Media Sensor and selecting the ‘ correctly and reliably, calibration is required. Depending upon the model of your printer, there are different calibration methods.

2.2.1 Calibrating Non-Display Models

In ‘Calibration’ Mode, button functions adjust the media sensor to the media being used. Calibration can be performed either automatically or manually, as detailed below.



Notes: Printer and cutter faults are disabled during this procedure, but can still occur while printing “test” labels.

Also, factory defaults can be restored; see the Operator’s Manual for details.

2.2.1.1 Automatic Calibration

Automatic Calibration lets the printer establish the optimum media sensing values.



Note: Before calibrating, be sure the media sensor is set for the media type you are calibrating and that it is

properly positioned (see the Operator’s Manual for details); also, ensure that the Printhead Assembly is latched down and that the cover is closed.

2.2.2.2 Standard Calibration

During the Standard Calibration process, the printhead assembly can be raised for visual access to the media and media sensor. In addition, displayed sensor readings can be used to indicate the best position over the media. These features are helpful when using small, position-critical TOF notches or marks. Three readings are required:

• Empty: No media in the sensor.

• Gap (or Mark): Only the backing, notch, or reflective mark in the sensor.

• Paper: The label (with the liner attached) in the sensor.

Make sure media is loaded and that the appropriate Sensor Type has been selected, then perform the Standard Calibration as follows:

Adjustments and Maintenance

2.3 Media Width Adjustment

To maintain even pressure distribution across media that is less than the width of the platen roller, the printer requires a Media Width Adjustment. Whenever using media that is less than four inches wide, proceed as follows:

1. Load media, then generate a batch of labels –

Non-Display models: Simultaneously press the

PAU S E

Display-equipped models: Select a quantity of Print Quality Labels (see the Operator’s Manual for

details).

2. While printing, loosen the Thumbscrew then move it to the left-most position. (The printing on the labels should fade, as shown in Example 1, below.)

3. Move the Thumbscrew to the right until the labels contain a complete, even image (see Example 2) and then tighten the Thumbscrew.

FEED

buttons.

Example 1 – Over adjustment:

Too much adjustment produces an image that fades across the label. To correct this, decrease the Media Width Adjustment.

Example 2 – Correct adjustment:

Proper adjustment produces a complete image, with even print contrast across the label (see note below).



Note: Under-adjustment can cause ribbon wrinkling, lateral label movement, and

excessive wear on the printhead and platen roller.

Adjustments and Maintenance

2.4 Printhead Burn Line Adjustment

The Burn Line has been adjusted at the factory for strict compliance using 6.5-mil (.0065 inch) media, ensuring print quality across a majority of media types. In extreme cases, however, if media of a different thickness or rigidity is used (for example, heavy tag stock), print quality can change. Typically, thicker media requires a slight forward adjustment, while thinner media requires a slight backward adjustment.

To adjust the Burn Line:

1. Load the printer with your media (and ribbon, if required).

2. Loosen the two Locking Screws approximately ¼ turn counter-clockwise.

3. Turn the Adjustment Screws counter-clockwise until the burn line is past the platen roller vertex, then

4. The label should look light and uneven. Now, tighten the Locking Screws just until they are ‘snug’

If you have questions, contact a qualified technician or Datamax Technical Support before proceeding.

buttons.

Display-equipped models: Select a Print Quality Label (see the Operator’s Manual for details).

(tight enough to remove any play in the printhead assembly, yet loose enough to allow the Adjustment Screws to move the printhead).

5. Turn each

Adjustment Screw clockwise about a ¼ turn (or an 1/8 turn for finer adjustments, see note below). Print another test label and examine the print quality. Repeat this step until labels are produced with an even print contrast and an acceptable print quality.



Note: When the Locking Screws are ‘snug’, turning the Adjustment Screws counter-clockwise will NOT move the

printhead outward; if you have adjusted the printhead too far inward, restart the entire procedure.

6. Tighten the Locking Screws. Print a final Test label to verify the adjustment.

2-19

Adjustments and Maintenance

2.5 Printhead Pressure Adjustment

To accommodate a variety of media types, the pressure applied by the printhead assembly is adjustable. This pressure is factory set to work with most media types, so this adjustment should only be performed after attempting to improve print quality through the use of the (1) heat and/or (2) print speed. When adjusting, use only the minimum pressure necessary for better imaging. To adjust:

1. Load at least 4-inch (102 mm) wide media and ribbon.

2. Ensure the Media Width Adjustment is disengaged (its left-most position); see Section 2.3.

3. Print a test label.

Non-Display models: Simultaneously press the

PAU S E

Display-equipped models: Select a Print Quality Label (see the Operator’s Manual for details).

4. Turn the Printhead Pressure Adjustment Screws counterclockwise to increase the applied pressure or clockwise to decrease the pressure. Make equal

adjustments to each screw to achieve even print

contrast across the media.

FEED

buttons.



Notes: 1) When using narrow media it is sometimes necessary to increase the pressure on the inner (closest

to centerplate) Printhead Pressure Adjustment Screw to prevent ribbon smudging.

2) Excessive pressure can reduce the service life of the printhead and platen roller.

3) Unequal pressure may cause ribbon and label tracking problems.

2-20

Adjustments and Maintenance

2.6 Ribbon Alignment

Correct ribbon alignment ensures smooth, taut ribbon flow during the print process. When irregular voids extend diagonally through the printed images on thermal transfer-equipped models, the cause may be due to ribbon overlapping (wrinkling). Begin troubleshooting by checking the Media Width Adjustment (Section 2.3), Printhead Pressure Adjustment (Section 2.5), and the Printhead Burn Line Adjustment (Section 2.4). Also examine the Platen Roller for signs of wear, debris build-up and excessive side-toside play. If all of these adjustments and components are in good order, then proceed with the Ribbon Alignment as follows:

1. Load 4-inch (102 mm) or wider media. Load a matching ribbon, but do not secure the leader to the Ribbon Take-up Hub. Instead, allow the media and ribbon to feed together from the printer.

2. Ensure the Media Width Adjustment is disengaged (its left-most position); see Section 2.3.

3. Press the FEED Button several times to normalize the tracking of the ribbon and media. (Continued excessive side-to-side [lateral] movement of the labels must be corrected before proceeding - typical causes include uneven printhead pressure, a worn platen roller, or worn platen bearings.)

4. Observe the ribbon for rippling and bagging as it travels down from the Ribbon Supply Hub and under the Printhead Assembly. If the travel is smooth, proceed to Step 5; otherwise, loosen the Ribbon Idler Screw then, while repeatedly pressing the FEED Key, slowly turn the Ribbon Idler Cam until the ribbon is dispensed smoothly from the Ribbon Supply Hub to the Printhead Assembly. Carefully tighten the Ribbon Idler Screw and feed several more labels to verify adjustment, repeat if necessary.

5. Attach the ribbon to the Ribbon Take-Up Hub then proceed according to printer type –

Non-Display models: Simultaneously press the

PAU S E

FEED

buttons.

Display-equipped models: Select a quantity of Quick Ribbon Test labels (see the Operator’s Manual

for details).

6. Begin printing. Observe the ribbon for rippling and bagging as it travels up from the Printhead Assembly to the Ribbon Take-Up Hub. If the travel is smooth and the printed labels show no evidence of ribbon wrinkling, proceed to Step 7; otherwise, slightly loosen the Ribbon Shield Adjustment Screws. Move either side of the Ribbon Shield ‘in’ or ‘out’ to smooth the ribbon and remove any wrinkle-related voids from the printed labels. Carefully tighten the Ribbon Shield Adjustment Screws. Print several labels. Verify the adjustment and repeat if necessary.

7. Install operating media and ribbon. Set the Media Width Adjustment, as needed (see Section 2.3). Send your label format to the printer from the host. Examine the printed labels; readjust the Ribbon Shield slightly, if needed.

2-22

Adjustments and Maintenance

2.7 Darkness Adjustment

The Darkness Adjustment allows compensation for changes that may occur in print contrast following a printhead replacement. Depending upon the printer model, this adjustment is accomplished as follows:

Non-Display models:

Turning the Darkness Adjustment in a clockwise direction will darken the print, while a counterclockwise adjustment will lighten the print. Following a printhead replacement, compare a label printed with the old printhead to one printed with the new printhead. If the darkest portions of the label are different, turn the Darkness Adjustment until the labels match.

Display-equipped models:

Using the Menu System, go to Print Control / Custom Adjustments / Darkness (see the Operator’s Manual for details).



Note: Large increases in the ‘Darkness Adjustment’ can shorten printhead life. If you need to increase the

darkness of the printed labels, try increasing the Heat value and/or slow the Print Speed using your software program or via DPL commands; see the Operator’s Manual for details.
