When calling for service, you will need to know your printer's machine (model) type and serial number. This information can be found on a label on the inside of the printer (refer to the instructions below). This label also lists the printer's part number (TLI) and config ID number (CID).
NOTE: The printer serial number is also listed on the menu settings page(s) you can print from the printer operator panel. For instructions on printing a menu settings page, click here.
