    Default Alps Printer/Plotter Mech NEW brass pinion gears

    In the 1980s the Alps 4-pen printer/plotter mechanism was used by almost every home computer manufacturer, for portable computer printers as well as a number of pieces of medical equipment. While they were not fast, they were compact, and did allow for 4 color printing/plotting at an affordable price.

    Over the years they all develop the same problem however, the pinion gears on the stepper motors crack. Plastic shrinks over time and a small plastic gear pressed onto a steel shaft will most likely succumb to age and split. While there have been some 3D printed gears available, they are expensive and not as strong as the original injection molded plastic gears.

    After searching for a few years now we finally found a manufacturer that could reproduce these gears in a reasonable quantity and reasonable price and out of brass which will last a lifetime. Now it is possible to fix all those old Alps mechanisms and get them printing/plotting again.

    The gears are sold in a set of 2 which is enough for 1 printer/plotter mechanism. They must be pressed into place, but you can make a simple tool to do so form a 2”/50mm C-clamp. See the link to the installation video which also shows how to make the tool to press the gears on.

    They are available on my website and also on eBay. Links below.

    What’s included
    1 set of two brass gears, 0.25M, 13 Teeth

    Pricing:
    $6 for 1 set of 2 new brass pinion gears
    $5.50 for 2+ sets
    $5 for 4+ sets

    Shipping: The gears are small and light so many of them will fit in a padded envelope. This is an estimate of the lowest cost shipping method. You can use the shipping calculator on the website to check for your specific location and choice of shipping method.

    USA: starting at $3 for First Class Mail shipping
    International: starting at $6 for First Class Mail International shipping
