ICON SP-250 Electronic Punch Clock — Discontinued but Still Supported

The ICON SP-250 electronic punch clock was a popular choice for businesses that wanted a simple, reliable way to record employee time without moving into software-based or networked systems. Designed as a straightforward electronic punch clock, the SP-250 allowed employees to insert a time card and produce a clear printed record for payroll verification. While the clock itself has now been discontinued, many units remain in daily operation, and replacement ribbons are still available to keep these machines working.

The appeal of the SP-250 was its simplicity. There were no badges to manage, no software to maintain, and no network connections required. Employees inserted a card, the clock printed the date and time, and the record was complete. For smaller offices, workshops, and service businesses, this approach reduced payroll errors while keeping the timekeeping process easy for both employees and supervisors.

Electronic punch clocks like the SP-250 became common because they combined the reliability of traditional punch clocks with improved print accuracy and reduced maintenance. The internal printing mechanism produced consistent, readable impressions that could be reviewed later for payroll processing or attendance tracking. As long as the ribbon was replaced periodically, the clock continued to produce clear records year after year.

Why Ribbons Still Matter

Even though the ICON SP-250 is no longer manufactured, the most common maintenance item has always been the ribbon cartridge. Over time, ribbons naturally fade, resulting in lighter prints that can make time cards difficult to read. Replacing the ribbon restores print clarity and allows existing clocks to continue operating without interruption. Replacement ribbons remain widely available because so many SP-250 units are still in service today.

Businesses maintaining an existing SP-250 often choose to continue using the system as long as it remains mechanically sound. The design was straightforward, and routine consumables such as ribbons allow these clocks to stay functional long after production has ended. Keeping a spare ribbon on hand is typically the easiest way to avoid payroll disruptions caused by faded or incomplete printing.
