    [Misc] MX-M623N Web Roller not rotating

    Recently I've come in contact with a MX-M623N, which I'm not as familiar with as other sharps. First of all the Machine had a FK3 maintenance code - which is to change the web rollers. (We just got this machine on contract from another company)

    I went to the site and began installing the maintenance kit that consisted of upper and lower web rollers. As I was doing so I noticed the webs were nearly brand new, there was an obvious stop and start thing happening creating a build up of crusty toner a few inches between each other. I continued to unravel the web roller and noticed at one point it was working properly. I then assumed he put it in wrong or something, and installed the web roller kit. Once I was finished I cleared the maintenance code and tried to test it. The code wouldn't clear even after a few tries.

    So basically the same thing is happening.

    There is a motor that drives the lower web roller, does this constitute a bad motor? not sure what to think.

    Sounds like the web was put in incorrectly by a tech from the previous company. Pretty sure there is a one way gear on that web unit that was probably put in backwards.

        Not sure with this model but on others, if the web empty sensor is activated, the web will stop turning and the machine will display a maintenance code.

        Make sure the web is installed properly especially if you have the empty sensor present.

          There is a tech bulletin that just came out that adds a spring to the web unit to prevent it from getting this code. The sensor flag will wind up on the wrong side of the web and give the FK3 message.

          Good luck.
