E-ZPass Runs Into Problem

img src="/sites/default/files/images/articles/printeditiontag_new.gif" width=120 align=right>Some state officials said the automatic toll payment devices that truckers and car drivers use in the Northeast’s E-ZPass system were faulty and more than 900,000 would be replaced.

But an official of Mark IV, the company that makes the transponders, said there was no problem with them and that the firm was merely replacing units routinely as they wore out.

Reported problems with transponders not transmitting information were caused by improper installation of toll payment electronics, said Mike Zimmerman, Mark IV’s vice president of business development.
