7. SUPPLY SPECIFICATIONS 7.2 Ribbon (7) Printing on Bump (Chip/Antenna) Area Embedding an RFID tag in labels creates bumps on the label surface, causing incomplete printing. Uneven printing or incomplete printing can occur easily, especially within 5 mm top and bottom, and to the left and right sides of the RFID-tag embedded area, as shown in the figure below. NOTE: The degree of poor printing quality differs depending on height of a chip/antenna used. Media feed direction RFID-tag Embedded area 5 mm Poor printing may occur in this area due to a bump. 5 mm Poor printing may occur in this area due to a bump. (8) Ambient Temperature As low temperatures cause wireless performance to deteriorate, writing data on an RFID tag may fail under such conditions. (9) Strip Issue Stripping performance in strip issue mode depends on the type of adhesive, tag, and backing paper. For some RFID supplies used, a strip issue may not be performed properly. (10) Caution for Minimum Label Pitch Length When using media, with a short label pitch length, data may be written on an RFID tag adjacent to the target RFID tag. As the location, where data is to be written, differs among RFID tag types, a check must be performed to make sure that the data is written on the target RFID tags. For details, please contact the nearest Oki Data support representative. (11) Defective RFID Supply RFID supplies may include defective RFID tags at the time of shipment from the maker. The defect rate differs depending on tag types, method of converting to supplies, etc. The RFID supply manufacturer should provide a way to identify defective tags by printing a mark on them or any other methods. Or, defective tags should be rejected in the production process. The end users must be notified on how to identify a defective tag from a good one. E7-7
