The Printhead Burn Line

If you have been feeling berned lately it may have nothing to do with Hillary Clinton or Donald Trump and everything to do with your printheads. You may not be aware of this, but the speed of your printer is directly married to the speed or “pulse rate” of your printheads. If you are receiving frequent error messages on your printer it may be because you have a lower quality printhead.

Just as in presidential elections, if the pulse rate of your printhead is too slow to keep up with your printing needs it will drop-out or burn-out. When your printheads are functioning properly it is creating what is known as a “burn line” which are tiny dots that string together in a row to produce information.

Printing problems arise when your printer is forced to produce burn lines at a much slower speed than it requires. Consumers who are exploring alternative printheads should place two particular printhead accessories on their checklist.

Thermistor, aka Mr. Cool  

Just as putting a low grade gasoline into a Porsche will burn-out its high performance engine the same is true for your printheads. To elaborate, a printhead must reach a temperature of 90 degrees Celsius to produce a black dot on a burn line.

However, that same burn line must subsequently cool down significantly and quickly to  approximately 50 degrees Celsius to produce a white space.  This rapid acceleration and deceleration is quite taxing on any printhead. To combat the issue of printhead pulse rate overheating, certain printheads come with tiny thermistors built-on. Printheads designed with thermistors allow it to heat up and cool down properly at any pulse rate without overheating.

Unlike politics, printheads do have a running mate who can take over if they fail. Settling for printheads without the thermistor will leave your print jobs stranded on the side of the road.

Dot History always repeats itself imgres

The term “history repeats itself” is far from new, however it is quite true when discussing the second most important feature to consider when selecting a new printhead, which is dot history.

A closer look at dot history shows that dot history control is typically found on more advanced printheads. Dot history works by memorizing previous pulse rates and burn lines. Dot history will take this information and store it for the production of future burn lines. Dot history’s ability to recall prior burn lines and temperatures to create successful future burn lines while managing printhead temperature extends the life of your printhead.

Ultimately, dot history may be the most valuable step in your printhead producing the sharpest burn line on your prints. A printhead without dot history is far more likely to experience printhead burn-out, dot bleed over, and increased printer energy expenses. Dot bleed over happens when the printhead cannot reduce the temperature fast enough to cause a complete white space to print and could ruin your print jobs.

As mentioned earlier, certain printheads on the market come with thermistors to manage the temperature of the printhead. Specifically, dot history acts a warning system for the thermistor. The dot history feature essentially predicts when and where a greater increase in pulse rate (temperature) is needed to produce a black dot and alerts the thermistor to begin its cool down functions to produce a white space.

As you may imagine dot history’s ability to lessen the chances of your printheads feeling the burn gives it the upper hand in the race for votes as the best printhead candidate for financially savvy business owners.

Printhead Primary

Just as in politics, buying a new printhead always comes with the fear of getting berned. Printhead manufactures are skilled politicans when it comes to over-promising.  However, a thorough fact check of their claims shows that printheads without thermistors and dot history go up in smoke fast.
