The lathem 1600E tru-align time clock and stamp has multiple uses. As a time clock, the 1600E records employees' in and out times for payroll processing. As a job clock it can track project time for accurate costing. And as a document stamp, the 1600E can print over 200 different time, date and Comment print formats. This time clock uses lathem's patented tru-align feature that lets your employees make the perfect-punch on their time cards every time. Using the optional tru-align compatible time cards, the tru-align technology senses when the printer is aligned correctly with the proper space on the time card and then it will automatically trigger an Imprint. The bright LED light illuminates the print area for easy viewing of time card punches or document Stamping. The 1600E wirelessly synchronizes with nist atomic clock in Colorado and automatically updates the time during daylight savings. It never needs resetting so the 1600E keeps time and your print settings during power outages. Use standard time or job cards, or optional lathem e16-100 tru-align cards (sold separately). mounts easily to wall or desktop (hardware included.) since 1919, lathem time clocks have set the standard for quality, durability and accuracy.
