The continued increase in the number of checks printed on laser MICR printers has raised a concern about the MICR print quality produced by these devices and the resulting performance on the various high speed reader/sorters such as the IBM 3890®. This paper shows that with proper toner selection and fuser temperature settings, reader/sorter performance problems are minimized. Toner adhesion enhancement agents in the paper will improve fusing latitude but not dramatically.

The adhesion failures generated by the reader/sorter are very similar to those generated using tape transfer of the toned characters. Good tape transfer measurement results will effectively predict good reader/sorter performance.

In addition an attempt was made to correlate the failure modes of checks rejected by the 3890 to the readout of a conventional waveform check qualifier. The qualifier was unable to detect the same failures.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
