How to Find Your Printer’s Model, Serial and Part Numbers

The labels and status pages that identify your printer exactly, and the details that prevent ordering the wrong part.

Why the series name is not enough

The name printed on the front of a printer usually identifies a family, not a specific machine. Models in the same family can use different cartridges, trays, fusers and firmware. The full model number, and sometimes the serial number, is what tells a supplier or technician exactly what you have.

The rating label

Most laser printers carry a rating label with the full model number, the serial number and the electrical rating (voltage and frequency). Look on the back panel, underneath, or inside the front or toner access door. If the label is hard to read, a clear photo works well.

The configuration page

Almost every laser printer can print a configuration or status report from its control panel menu. It usually lists the model, serial number, firmware version, total page count and the remaining life of each consumable. For networked printers, it also shows the IP address, which helps with connectivity questions.

Cartridge and consumable numbers

The cartridge number is printed on the cartridge label itself, and often on the supplies status page. Drums, imaging units, waste toner containers and maintenance kits have their own numbers. When a printer accepts more than one cartridge size, the number tells you which one you have now.

Part numbers on wear parts

Fusers, rollers and trays often carry a part number on a label or molded into the plastic. For voltage-specific parts such as fusers, check the voltage too: printers in the United States use 110–127 V parts, and a part built for a different voltage will not work correctly.

What to send with an enquiry

  • Full model number and, for parts, the serial number.
  • The cartridge or part number from the item you are replacing.
  • The quantity you need.
  • For repairs, the exact wording of any error message and a photo of any print defect.

With those details, our supplies enquiry or repair request can be answered without back-and-forth.
