4.2 Loading Paper 63
4. Adjust the side paper guides to the size of 
the paper.
Important
• Make sure that the guides are positioned just lightly 
against the paper. Guides that are too tight or too 
loose can cause paper jams.
Note
• Do not fill paper above the maximum fill-line. Doing so 
can cause paper jams.
Note
• When printing from Tray 1 (Bypass tray), set the size and type of the paper on your print driver. For more 
information, refer to the online help provided for the print driver. 
• When [Bypass Mode] is set to [Panel Specified] (default: [DriverSpecified]) on the control panel, or when 
[Paper Size] is set to an option other than [Driver] (default), set the size and type of the paper loaded in 
Tray 1 (Bypass tray) before requesting a print job.
The printer prints your job only when the settings on your print driver match the settings on the control 
panel. For more information, refer to " [Bypass Mode]" (P. 103).
