When printing from your printer’s internal tray, the weight of paper you can use is 60 to 90 gsm.
Using a straight-through paper path (i.e. from the manual or by pass feed and out the back of the printer) the maximum weight is increased to:
135 gsm for FS-400, FS-1500, FS-1550/+, FS-1600/+, FS-3400/+, FS-3600/+, FS-6500
163 gsm for FS-600, FS-680, FS-800, FS-1000
200 gsm for FS-1200, FS-1750, FS-1800, FS-3750, FS-3800, FS-7000/+, FS-9000
The FS-1700/+, FS-3700/+, FS-1750 and FS-3750 can have a replacement internal cassette to support heavier weight A4 paper (90-135gsm).
Using a duplex unit on a model requires paper to be within the weights shown in the table below – using lighter or heavier paper could result in serious jams.
