*1 Proper feeding of paper may not be possible at the maximum capacity depending on the type of paper
or environmental conditions (either very high or low temperature or humidity). In such cases, reduce the
number of paper you load at a time to less than half.
*2 We recommend that you remove the previously printed envelope from the paper output tray before
continuously printing to avoid blurs and discoloration.
*3 When loading paper in stacks, the print side may become marked as it is fed or paper may not feed
properly. In this case, load one sheet at a time.
