The “Paper Mismatch” or “Paper Size Mismatch” error can occur when the paper, envelopes or other media loaded in the printer tray or feeder is a different size than the paper selected in the printer settings and is a safeguard programed into your printer to prevent ink or toner from being wasted.
Some printer models have an option that allows you to ignore the error and continue printing regardless of the mismatch. If you choose to ignore the error, the margins on your printout might not be proportional to the edges of the paper.
Step 1: Adjust the paper size setting
Check the paper size setting to make sure it matches the paper you want to print.
1. In the program you want to print from, click File, and then click Print.
2. Make sure your printer is in the Name or Printers drop-down list box, and then click Properties, Printer Properties or Preferences, depending on the program options.
3. Click the Paper/Quality tab.
4. Click Advanced, if necessary, and then click Paper Size.
5. Select the paper size that matches the size and type of paper loaded in the printer tray, and then click OK. If there are no matching paper sizes, select the size from the list that is closest to the size of the paper loaded in the tray.
6. Click OK, and then try to print.
If the error message persists, continue to the next step.
Step 2: Check the paper source setting
Remove and reload the paper in the input trays, and then check the paper source setting.
1. Remove all the paper from all the printer input trays.
2. Reload the paper, and then adjust the paper width guides so they gently rest against the edge of the paper stack.
3. In the program you want to print from, click File, and then click Print.
4. Make sure your printer is in the Name or Printers drop-down list box, and then click Properties, Printer Properties or Preferences, depending on the program options.
5. Click the Paper/Quality tab, and then click Paper Source to select the correct tray.
6. Click OK, and then try to print.
If the error message persists, continue to the next step.
Step 3: Reset the printer
Reset the printer to clear any hardware issues or error states.
1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Unplug the power cord from the wall outlet.
3. Wait a minimum of 60 seconds.
4. Plug the power cord back into the wall outlet.
5. Reconnect the power cord to the rear of the printer.
