Why the exact model matters

Printer ranges share family names, but models within a family can use different drivers, cartridges and parts. “An HP OfficeJet” or “a Brother laser” is not enough to choose the right software or diagnose a code. The full model number is.

Where to look on any printer

  • Front or top panel: the family name and often the model are printed near the controls.
  • Label on the back or underneath: a rating label shows the model number, serial number and regulatory details.
  • Inside the front door or cartridge area: many printers repeat the label here.
  • Configuration page: printing a configuration or status page from the menu lists the model, serial number and firmware version.
  • Computer: the printer entry in your system settings usually shows the model name.

Brand-by-brand notes

  • HP: look for the model and a separate product number on the rear or inside label.
  • Canon: the model name is printed on the front; the label with the serial number is often on the back or inside.
  • Epson: the model name is on the front or top; the serial number is on the rear label.
  • Brother: model codes such as HL, DCP or MFC followed by numbers appear on the front; the serial label is usually at the back.
  • Lexmark and Xerox: office devices usually show the model on the front, and the configuration or menu settings page lists the serial number.

Include it in your repair request

Adding the model number, and the serial number if the request is about a fault, helps us check compatibility and prepare before we contact you.

General guidance only. Follow your printer’s manual and safety warnings, and unplug the printer before reaching inside.
