Squeaking, Grinding and/or Clicking Noises
• Squeaks (idle rolls, torque limiter), clicks (clutch, feed belt), and
intermittent grinding noises (transport drive 1st mesh, clutch) have
could be objectionable to a customer.
• To resolve the issue, do the following:
– Squeaking Noise – add dry lubricant to idle rolls
– Clicking Noise – clutch will click against its rotational stop every time it engages,
feed belt assembly will click against outer guide, both are normal
– Grinding Noise – deskew clutch can make a grinding noise if parts are out of spec
or it is damaged (replace clutch); grinding noise can also occur if the transport
drive bracket studs are damaged (replace transport drive)
