Cause of error code 41.3 UNEXPECTED PAPER SIZE

The printer detected a media size different from what it was expecting. This is typically caused if two or more sheets stick together in the printer or if the tray is not properly adjusted.

Solution for error code 41.3 UNEXPECTED PAPER SIZE

1. Reload the tray with the correct print media size. 2. Ensure that media in the tray is loaded under the front and back retaining tabs. 3. If you are printing from tray 1, verify that the correct paper size is selected in the control panel. 4. If you are printing from tray 2, 3, or 4, verify that any paper-size adjustments (length guide, width guide, size-selector switch) on the paper tray have been made correctly. Make sure the media is under the corner tabs. 5. After performing the actions above, press GO. The page containing the error will automatically be reprinted if jam recovery is enabled. (Or, you might want to press CANCEL JOB to clear the job from the printer’s memory.) For the 4000, 4050, and 4100 series the paper feed assembly could be bad. Also the paper feed/registration sensors could be knocked out of place. On EX engine printers this error is caused by a bad PIU (paper input unit).
