Fuser Types
There are many Fuser Types identified by a unique Fuser Type code (see the section in this guide called
How to Determine the Correct Fuser Part Number). It is critical that the correct fuser is identified and
replaced in the machine. It is important to note that Hot Roll and Belt Fusers ARE NOT interchangeable.
If a customer chooses a Hot Roll printer type, they cannot convert it to a Belt Fuser machine and vice
versa.
The different fusers are based on the following variables:
 Printer Model
 Voltage (100V, 110-120V, 220-240V)
 Media Size (A4 vs. Letter – applies to Belt Fusers only)
 Hot Roll or Belt
 Return Program or Regular
The Belt Fusers come in both A4 and Letter sizes to prevent damage to the fuser. Although either fuser
can print on both Letter and A4, running large amounts of the alternate size media can damage the fuser.
The printer will recognize if A4 is printed on a Letter fuser (and vice versa) and try to compensate to
minimize the risk of damage. The behavior is as follows:
