4340 Ink Roller Replacement (See Figure 2)

It is recommended that ink rollers be changed every three months.

1. Place the imprinter upright, with its front side towards you, and the lid open.

2. While steadying the unit, pull the ink roller shaft (A) out of the bottom of the carriage (F).

3. Remove the ink roller shaft (A) from the top of the carriage (E). The roller and its shaft are now free to be removed from the carriage.

4. Remove the ink roller (B) from the ink roller shaft (A). The arrangement of any spacers should be noted before the roller is removed (see #5).

5. In some cases, the shaft will have spacers (C, D) as well as an ink roller. Please make careful note of the number and position of any roller spacers on the shaft as you remove them. Upon re-assembly, the spacers will have to be assembled in the same positions. The number, sizes and positions of any spacers is not standard, and depends entirely on the customized application of the particular unit being worked on.

6. Place the new ink roller (B) onto the roller shaft (A), with any required spacers (C, D).

7. Insert the outside end of the roller shaft (A) into the top of the carriage (E).

8. Press the pointed end of the roller shaft (A) into the bottom of the carriage (F), until it snaps into place.

9. Ensure that the ink roller (B) rotates freely.

 

 

  

IMPRINTER DENSITY ADJUSTMENT (see Figure 4)
Model 4340

Please note: Your imprinter should have been adjusted at the factory to meet the specifications of your cards and forms. Before making any adjustments, please replace your ink roller, this may solve your problem.

Imprint density is the darkness or lightness of the characters printed. Uniformity in printing is achieved by setting the imprint deck so that all printing is equally light or dark.

NOTE: If there is a dater in the unit, make sure to back it off so that it is not imprinting at all. To achieve this, simply turn the three screws (D, E) located on the top and sides of the dater counter-clockwise.

The imprint density is adjusted using four phillips head adjusting screws (A) on the deck. Since it only takes three points to define a plane, and the deck is mounted on four points (the four screws), any adjustment will require that two screws be turned, not just one.

1. Place the unit upright with the front side towards you, the lid open and the cord plugged in.

2. Loosen the two phillips head retaining screws (F) before making any adjustments.

3. Install a metal embossed station plate (if applicable).

4. Place the embossed plastic card in the card holder (B) on the anvil. Place a piece of paper over the card and plate (if applicable).

5. Close the lid. The unit should operate and the lid should open. It is possible that the unit may jam. If this occurs, unplug the unit, operate the release lever underneath the unit to open the lid.

6. Observe the imprint on the paper.
· If the imprint is extremely dark or caused the unit to jam, the screws (A) must be adjusted approximately a half turn counter-clockwise.

· If the imprint is too light or non-existent, then the screws must be adjusted approximately a half turn clockwise.

· If the imprint is too heavy in one corner, and too light in another, the screw in the heavy corner must be adjusted counter-clockwise, and the screw in the light corner must be adjusted clockwise by the same amount.

· If the station plate imprint (if applicable) is much lighter than the card, then a plastic or metal shim (C) must be installed under the station plate. These shims are available in 0.005" and 0.012" thickness. In most cases, a 0.005" shim is required.

· After every adjustment, try rocking the deck diagonally to test that all of the screws are properly seated. This ensures reliable imprints.

7. Repeat Steps #5 & #6 until the imprint is satisfactory.

DATER IMPRINT ADJUSTMENT (if applicable)

NOTE: The imprint adjustment to the deck (card and any station plate) should be completed before adjusting the dater imprint.

1. Place the unit upright with the front side towards you, the lid open and the cord plugged in.

2. Install a station plate if the unit takes or requires one. Place the embossed card in the card holder (B), and set all the numerals on the dater to "8". The number "8" is the fullest numeral, making the imprint adjusting somewhat easier.

3. Put in a piece of paper and close the lid. The unit will operate and the lid will open.

4. Examine the imprint on the paper.

· If the dater imprint is lighter than the card & plate or is non-existent, then the two dater imprint screws (D) at both sides of the dater must be turned clockwise.

· If the dater imprint is much heavier than the card & plate, then the two dater imprint screws (D) at both sides of the dater must be turned counter-clockwise.

· If one end of the dater line is too light, then the screw on that end must be turned clockwise.

· If the one side of the dater characters (top or bottom) is heavier than the other, then the dater roll screw (E) must be turned counter-clockwise. If the side closest to the screw is lighter than the other side, then the dater roll screw (E) must be turned clockwise.

5. Repeat Steps #3 & #4 until the dater imprint is equal in density to the card (and plate, if applicable).
