How to Switch Paper Rolls
Here we will explain how, in certain situations, paper roll 1 and paper roll 2 are switched. Refer to this
information when necessary, for example, when documents will not print as expected, etc.
If you select Roll Paper (Auto) under Paper Source in the Page Setup tab, of the two paper rolls loaded in
the lower and upper trays of the printer, the one best suited for the print job will be automatically selected.
Whether paper roll 1 or paper roll 2 will be used, is determined through a sequence of judgment based on
the 7 conditions in the table below.
At such times, the Printer settings -> Paper-related settings -> Detect paper setting mismatch in the
Printer unit's Operation panel will switch to the result of the judgment based on the process described below.
• If the Detect paper setting mismatch setting is set on Pause or Hold job
• If the Detect paper setting mismatch setting is Display warning or Do not detect
Note
