Purpose of This Document: To instruct owners of Macdermid ColorSpan Wide Format Printers regarding methods to prevent updating of profiler chips so that UINK™ inks for ColorSpan may be used for refilling cartridges or bulk box dispensers or to reset chips for the same purpose.

By-Pass Method

Compatibility: For any ColorSpan printer using profiler chips which has not had firmware updated to prevent bypassing. This method does not prevent updating of printhead smart chips, only profiler chips may be affected.

Background: ColorSpan Printers utilize extensively modified versions of Hewlett Packard inkjet cartridges which are supplied with inks unique to ColorSpan printers. In addition to physical differences in the cartridges and inks, Macdermid uses specialized smart chips, which Macdermid calls “profiler chips” to curtail attempts to refill these cartridges. The cartridges can be refilled quite easily if the profiler chip is prevent from updating to an empty cartridge (or fully used chip) status. Firmware updates to more recent models may prevent the ability to use this method to prevent updates. You should verify that you can bypass your chips BEFORE purchasing any inks. It may be possible to rollback the firmware to older versions to permit bypassing.

Limitations Of Method: Successful implementation of this bypass method will allow the user to make single document prints without changes to the status count on the profiler chip. Multiple copies of the same object as a single job or multiple jobs as a single run are not possible with this method.

Procedure: This procedure is available in a *.pdf file which may be downloaded here.
