Yellow spots on the card

Problem：Light or spotty black text, barcodes, or images

Solution:

Mostly visible on white areas. This is due to contamination on the card, most likely the card surface has been touched, and the fingers left oil residue. 

Use new cards following proper card handling recommendations:

Cards should be handled as little as possible. 

Touching the surface of the cards can contaminate them with oil and particles from your hands. 

The surface of the cards must remain clean and dust-free. Always store cards in an enclosed container. 

Ideally, use cards as soon as possible.

Improper card handling may result in:

1. Poor print quality: See a Technical Bulletin on contamination effects. 

2. Damage or accelerated wear to your printer.

Cards must be handled by their edges. We recommend taking the cards directly from the manufacturer's packaging and 

installing them directly into the printer:

Procedure:

1. Remove the wrapping from the card stack.

2. Holding the card stack by the sides, hold it vertically against a flat surface such as a desktop. 

If the stack is too thick for your hand to hold it comfortably, use about half a stack at a time.

3. Push the stack back and forth to an angle of about 45° from vertical, so as to separate all of the cards.

NOTE：Static charges and edge burrs from the card die-cutting process can render individual cards stuck together 

with significant adhesion force. These cards must be physically separated from each other before inserting into the feeder;

if not separated, feeding or printing problems may occur.

4. Restore the card to its original squared-off condition.

5. Place the cards into the printer's card feeder.
