A clicking or gear skipping noise followed by a 202.93 paper jam

Issue description

A clicking or skipping gear noise emanates from the back-side of the printer around transfer belt height, and proceeds with a 202.93 jam message. This error is defined as a jam at the fuser entry, or the fuser exit sensor never turns on.

  1. Replace the Waste Toner Bottle (WTB) if it is clogged. If the WTB has no issues, continue to the next step.

    Note:  The WTB has a capacity of 50,000 pages. If the WTB is clogged or backed up, this leads to numerous errors including a 202.93 paper jam.

  2. Replace the transfer belt if needed. Refer to “Transfer belt removal” instructions for more information.

  3. Turn the printer On, then print a test page and check whether the issue persists.
