Explanation of the Cartridge Mismatch Error
A
42
or Toner Cartridge Region Mismatch
error indicates that the installed toner cartridge is manufactured for a different geographic region than the printer. The printer and the toner cartridge each have a certain geographical code tagged to them, much like the coding on DVD players and DVDs. Both must be coded to the same geography for them to work together. If you install a toner cartridge that does not match the region of the printer, the printer will post a Cartridge Region Mismatch
error. There are four different geographical regions:
- USA & Canada (North America)
- Europe, Middle East, & Africa
- Asia & Pacific Region (Indonesia, Australia, etc.)
- Latin America (Central & South America)
Regionalization also helps to protect users from counterfeit products and to protect authorized dealers and distributors from illegitimate dealers and brokers.
Clear or Confirm the Error Message
- Power the printer off, then power it back on after 20 seconds. Try printing again.
- If the error continues, confirm that the message posted on the printer is aToner Cartridge Region Mismatcherror.
- On theE350d,E352dnandE450dn(LCD panel)models, theCartridge Region Mismatcherror, or a42error, will be displayed on the printer screen.
- On theE250dandE250dn(LED light) models, this error will be indicated by a primary error where both the!light and the light will be on solid.

- If the error displayed is indeed aCartridge Region Mismatcherror, the printer region setting is different from the cartridge region setting. Check the region settings of the printer and the cartridge to see which one does not match the geography in which you are located. SeeCheck the Printer and Toner Cartridge Region Settingsbelow.If this error began after a brand-new toner cartridge was installed in the printer for the first time, power off the printer and reinstall the old toner cartridge. If the error goes away when you install the old cartridge, thenewtoner cartridge is the most likely cause of the error.

If the Toner Cartridge and Printer Regions Do Not Match

You may inform the dealer that the cartridge sold to you is not intended for sale in your region. If the dealer is unable to assist you, please contact customer support for further assistance.
- If you received this toner cartridge from a source other than an authorized dealer, you will need to purchase a new toner cartridge. To order supplies in the U.S., contact support at 1-800-539-6275 for information on Authorized Supplies Dealers in your area. In other countries or regions, visit the main site or contact the place where you purchased your printer.
- If the cartridge is in the correct geographic location but the printer is not, you will need to return the printer to its proper geographic location or else order toner cartridges that match the region the printer was designed to be used in. If this cannot be done or if the printer has been moved from its original geographic location, please contact customer support for further assistance.
If the Toner Cartridge and Printer Regions Match
