Canon BJ-200ex - Manual (Page 47)

6. Start your print operation.
§ If you are using Windows, you must select Manual Feed using the
BJ-200ex printer driver for the printer to accept manually fed
paper.
§ After printing on thick paper or envelopes, set the paper thickness
lever (inside the printer) to the left before printing on normal paper.
§ After manually feeding a sheet of paper or an envelope, set the
paper selection lever to the back position.
Printing on Transparencies
You can stack approximately 40 transparencies in the sheet
feeder. However, this special medium may not advance
correctly under unusual environmental conditions (such as
extreme temperatures and humidity). If you have trouble
with transparencies becoming skewed or feeding multiple
sheets, do not stack them in the sheet feeder. Load them
manually as described earlier in the chapter.
Place at least one sheet of plain paper in back of a stack of
transparencies.
