|The ITB or Intermediate Transfer Belt is a part found inside some HP Colorlaserjet printers.
Hewlett Packard OEM# CC468-67927 is the HP Color LJ CM3530 MFP/ CP3525 Series (ITB) Intermediate Transfer Belt Service Kit (150,000 Yield).
Hewlett Packard OEM# RM1-4436 is the HP Color LJ CM1312 MFP/ CP1215/ CP151/ CP1518 Series (ITB) Intermediate Transfer Belt Assembly.
Hewlett Packard OEM# RM1-4852 is the HP Color LJ CM2320 MFP/ CP2025 Series (ITB) Intermediate Transfer Belt Assembly.
Why do some color laser printers have a transfer belt while monochrome (black only) laser printers do not?
While monochrome printers only use one laser scanner assembly, color printers often have two or more scanner assemblies.
Color printing adds complexity to the printing process because very slight misalignments known as registration errors can occur between printing each color, causing unintended color fringing, blurring, or light/dark streaking along the edges of colored regions. To permit a high registration accuracy, some color laser printers use a large rotating belt called a "transfer belt". The transfer belt passes in front of all the toner cartridges and each of the toner layers are precisely applied to the belt. The combined layers are then applied to the paper in a uniform single step.
If the transfer belt is worn out on your printer, its probably a good idea to get a new printer. These parts from HP cost around $250 to $300 for the models listed above, add to that the cost and time to replace them, and you're probably better off buying a new printer.
