There are checks to make and steps to correct any problems.
Check that the sheet is more than 329 mm 12.95 in wide (A3+). If it is that width or less, load it from the multi-sheet tray.
Guide the sheet, especially thick papers, when the printer initially feeds the sheet.
Ensure that the sheet is aligned with the reference line on the roll cover.
Do not attempt to straighten the sheet during the loading process, unless instructed to by the front-panel display.
Do not use hand-cut sheets, which may be of irregular shapes. Use only purchased sheets.
In case of any problem, follow the instructions given on the front-panel display.
If you would like to start the load process again, cancel the process on the front panel; the printer ejects the sheet from the front of the printer.
