Epson C4100 Reference Manual - Page 50

If transparencies are loaded incorrectly, the message Check Transparency appears on the LCD panel. Remove the transparencies from the MP tray and remove the jammed transparencies from the MP tray. Open and close cover A to clear the message on the LCD panel, then reload the transparencies. The printer resumes printing from the page that jammed. ❏ When using transparencies, load them in the MP tray and set the Paper Type setting to Transparency in the printer driver. ❏ When the Paper Type setting in the printer driver is set to Transparency, do not load any other type of paper except transparencies. c Caution: Sheets that have just been printed on may be hot. Envelopes The print quality of envelopes may be irregular because different parts of an envelope have different thicknesses. Print one or two envelopes to check the print quality. c Caution: Do not use window envelopes unless they are specifically designed for laser printers. The plastic on most window envelopes will melt when it comes into contact with the fuser. Note: ❏ Depending on the quality of envelopes, the printing environment, or the printing procedure, envelopes might be wrinkled. Make a trial print run before you print on a lot of envelopes. ❏ Duplex printing is not available for envelopes. 50 Paper Handling
