What is that fine white line on my ID card?

The Fine White Line

We often receive calls from clients whose printed ID cards include a fine white line. This line always appears in the same place on the card and does not vary (though one may not notice it if there is not a text, image, or background color in that area). This symptom indicates one of 3 problems with the printer’s printhead:

  1. A piece of dust, dirt or debris is stuck to the printhead;
  2. The printhead has physical damage (such as a scratch or a nick);
  3. The printhead has had one or more imaging pixels burn-out. This usually results from an electrical surge or lighting strike.



A user can solve the first problem by manually cleaning the printhead with IPA alcohol wipes or swabs. (Find them here!)

The latter 2 problems are more common and require replacement of the printhead. Prior to purchasing a replacement, first check with your authorized dealer to see if the printhead is still under warranty. Virtually all top printer manufacturers’ warranties offer to replace a damaged printhead for a defined period of time following purchase of a new printer.

A word of caution: Please review your own printer’s warranty for any coverage requirements or restrictions. Many of these warranties require performing required cleanings on-schedule (usually about every 1,000 cards, but check your printer’s user manual for the exact number). Additionally, many warranties exclude damage caused by misuse, or use of sub-standard materials (i.e., cheap cards or non-brand ribbons).

Fargo DTC500 Printer Prints with White Pixel Lines Across the ID Card

It is common for our technical staff to hear a customer call and wonder why there is a white clear line across the ID cards that they are printing with their ID card printer. Following are pictures of two types of white lines on printed ID cards.

printhead damage

The white line in the above picture across the card is wide and is caused by physical damage to the printhead.

Printhead Problem

The light thin straight line across the card is normally caused by a bad pixel in the printhead. Although a line this thin can be caused by a damaged printhead, it is usually due to a burned out pixel.

To correct either of these problems, the printhead assembly needs to be replaced. For information about Fargo printer printhead replacements with the Fargo DTC550 or other Fargo printer models, contact our ID card experts at 888-485-4696.

Fargo DTC550 Printer Head Pressure Adjustment

Head Pressure Adjustment

The following procedures provided from technical support personel are offered to balance the printhead pressure on the DTC-550 series printers. You may need to balance the printhead when the edges of the top or bottom of the the plastic ID card print too light.

Warning! Remove all jewelry, rings, watches, bracelets etc. from your wrists and hands before beginning work with the printhead. The printing edge is extremely fragile and is easily damaged. It is strongly advised that you work in a static protected area.

Loosen but, do not remove, the two peel off bar hold down screws. DO NOT let the peel-off bar come into contact with the printing edge as it may result in damage that can seriously affect print quality.

To balance the printhead pressure, either lower the end of the printhead that is printing light or raise the opposite end of the printhead. Typically, the printhead is assembled with the print edge at its lowest point making it necessary to raise the end of the print edge that is opposite the light edge. Usually about 1/64 of an inch is sufficient. Raising or lowering the print edge too much will result in a light edge on the opposite side of the card.

After loosening the two peel off bar hold down screws, only loosen the printhead mounting screw on the end of the printhead that you wish to raise or lower. DO NOT loosen the other printhead mounting screw.

Using a small pocket sized screwdriver, carefully pry the head of the loosened printhead mounting screw to raise or lower that end of the printhead.
