    The Samsung Ricoh SP4100 series of

    printers are based on a Ricoh 31-36ppm,

    1200 x 600 dpi engine. All models have a

    'rst page out in less than 6.9 seconds. (Not

    7 seconds 6.9 seconds, hows that for

    being speci'c!)

    2ese are not the easiest cartridges to do,

    but if care is taken they are not too bad and

    the profits are nice! Care must be taken

    not to disturb the doctor blade as it is very

    di3cult to set back properly. 2e entire Db

    assemble can be removed though so its not

    a problem. 2ese cartridges also us a chip

    that must be replaced each cycle. 2ere is

    a HY and a LY cartridge and both have a

    different chip. To install the replacement

    chips you will need to unsolder the old

    chip and solder on the new one. The HY

    cartridges only work in the 4100N and

    4110N, the LY only in the 4100NL

    2e models in this series are:

    Ricoh Aficio SP-4100N KP (Uses HY

    cartridge and chip only!)

    Ricoh Aficio SP-4100NL (Uses LY

    cartridge and chip only!)

    Ricoh Aficio SP-4110N KP (Uses HY

    cartridge and chip only!)
