    ricoh 2238c

    2238c makes a grinding sound, and then jams, you can see the transfer unit belt cleaner rotating, and actually slowing down when the grinding starts as if something is jamming it up

    it will do this on start up , when it does it cycle before copy ready mode, and then of course will do it all the time once it tries to do copies, listening in via driver shows thats it defineltey the transfer belt unit itself jamming , what could cause it to jam

    sometimes it does go ok but most of the time jam kicks in

    There is a drive shaft that goes from rear to front. Clean and turn the bushings 180 degrees.

    Why do they call it common sense?

    If it were common, wouldn't everyone have it?

    ok i seem to have found the issue, the drive belt unit itself is getting jammed, i have cleaned and lubricated the shaft within this and adjusted the motor belt tensioner and the problem hasnt come back yet, also cleaned up all the other cogs , gave a silicon wipe for smoother running as most are plastic

    Try reducing the ITB cleaning blade pressure. (Stretch the tension spring.) I've seen the blade catch and bind up the belt.

    Don't take that toner with me!

    another way to see if it is transfer>>>Does it pass "line position setting"? Is it logging sc codes?

    i have come across this problem many times before.

    firstly remove the cleaning unit and see if it makes the same noise. if i still does then it might be toner on the gears on the back of the transfer unit. u may want to order a new cleaning unit anyway.

    check the gears on the back and see if their worn out.

    make sure your not geting toner spiling on to the gearson the back of the t unit.

    and more importantly make sure u vac out the waste toner tunnel pipes beacuse a build up of toner can cause this noise too. especially the cyan and yellow tunnel.

    replacing the belt may be a good idea too if it hasnt been changed.

    ok will do the vac again, but tell me this the gears on the cleaning unit are fine, when i remove the cleaning unit the problem is still there, u can see the transfer belt completely slow down as the jamming starts to occurr, the cogs on the fron and rear of the belt unit itself are fine, so something is intermitently getting into a stuck position, the machine went fine when i greaed up some of the rollers for a while or shafts i should say,

    any of you recommend complete strip down of the unit?

    just for your info, forgot to post the answer to problem, vacing the transfer unit cleaning all the gears and shafts corrected the problem, i am assuming after so many copies and age you get some toner spill and it needed a good clean, hopefully thats the end of it, been running for a few months now
