1. Introduction

1.1 Product Introduction

Thank you very much for purchasing our thermal transfer printer.

This printer is designed with die-casting aluminum chassis and print mechanism, metal cover with large clear media view window, which ensuring to work for the extreme and heavy duty industrial environment and applications.

With a back-lit graphic LCD display, the printer status is user friendly and can be easily managed. The moveable sensor design can accept wide range of label media. All of the most frequently used bar code formats are included. Fonts and bar codes can be printed in any one of the four directions. This printer is built-in the high quality, high performance MONOTYPE IMAGING® True Type font engine and one CG Triumvirate Bold

Condensed smooth font. With flexible firmware design, users can also download True Type Fonts from a PC into the printer memory for printing labels. In addition to the scalable font, there is also a choice of five different sizes of alphanumeric bitmap fonts, OCR-A and OCR-B fonts. By integrating rich features, it is the most cost-effective and high performance printer in its class!

2.7.1 Print head Pressure Adjustment Knob

Kroy K4730 - Print head Pressure Adjustment Knob - 1

natural_image Close-up of a metallic mechanical component with three green circular switches and a red measurement line (no text or symbols visible)

Print head pressure adjustment knobs

The print head pressure adjustment knob has 5 levels of adjustment. Because the printer's media alignment is to the left side of mechanism, different media widths require different pressure to print correctly. Adjustment may required depending on media thickness and widths to obtain the best print quality. For example, if the label width is 4", adjust both print head pressure adjustment knobs to the same level. If the label is less than 2" wide, increase the left side print head pressure by rotating the adjustment knob clockwise and decrease the right side pressure by rotating the adjustment knob counter-clockwise to level 1.

2.7.2 Print Head Burn Line Adjustment Knob

Kroy K4730 - Print Head Burn Line Adjustment Knob - 1

natural_image Close-up of a mechanical testing machine with green and black components, showing paper roll and alignment lines (no text or symbols visible)

Print head burn line adjustment knobs

The print head burn line adjustment knobs are used to fine tune the print quality for

different thickness of media. Turning the knobs adjusts the print head's burn line forward or backward as it relates to the platen roller.

Caution: Incorrectly adjusting these knobs can lead to poor print quality and may cause damage to the printer. Proceed with caution.

The print head burn line default is set for general purpose printing media (plain paper and paper thickness less than 0.20mm).

Poor print quality when using paper thicker than 0.20mm may be due to the print head burn line not being at the optimized position. To improve the print quality, increase the head pressure or adjust the knobs counter-clockwise to move print head burn line toward the paper out direction then print again. Continue to adjust the burn line position and test print as necessary until the printout image is clear.

5.2 Mechanism Fine Adjustment to Avoid Ribbon Wrinkles

This printer has been fully tested before delivery. There should be no ribbon wrinkle presented on the media for general-purpose printing application. Ribbon wrinkle is related to the media thickness, print head pressure balance, ribbon film characteristics, print darkness setting...etc. In case the ribbon wrinkle happens, please follow the instructions below to adjust the printer parts.

The print head pressure adjustment knob has 5 levels of settings. Clockwise direction adjustment is to increase the print head pressure. Counter Clockwise adjustment can decrease the print head pressure.

If the wrinkle on the label starts from the lower left side to upper right side, please do following adjustment.

  1. Decrease the right side print head pressure adjustment knob setting 1 level per each adjustment then print the label again to check if wrinkle is gone.
  2. If the right side print head adjustment knob setting has been set to index 1 (the lowest pressure index), please increase the left side print head pressure.
  3. If the left side print head adjustment knob setting has been set to 5 (the highest pressure index) the wrinkle can't be avoid, please rotate the both knobs back to setting 1 then rotate the Z-axis mechanism adjustment knob clockwise for a few degrees and print again for fine tune the print head pressure distribution.
