Thick Paper
This section gives you various details about and recommendations concerning thick paper.
When loading thick paper of 127 
216 g/m2 (34 lb. Bond 80 lb. Cover) in paper trays or in the LCT, or of 127 256 g/m2 (34 lb. Bond 140 lb. Index) in the multi bypass tray, or of 127 300 g/m2 (34 lb. Bond 110 lb. Cover) in the Wide LCT, follow the recommendations below to prevent misfeeds and loss of image quality.
Store all paper together in the same place - a room where the temperature is 20
25°C (68 77°F) and humidity is 30 65%.When loading thick sheets, be sure to load at least 20 sheets. Also, be sure to position the side fences flush against the paper stack.
Smooth out any curls in the paper before loading it.
Jams and misfeeds can occur when printing on thick glossy sheets. To prevent such problems, be sure to fan glossy sheets thoroughly before loading them. If sheets continue to become jammed or feed in together even after they are fanned, load them one by one from the multi bypass tray.
Even if thick paper is loaded as described above, normal operations and print quality might still not be possible, depending on the paper type.
Prints might have prominent vertical creases.
Prints might be noticeably curled. Flatten out prints if they are creased or curled.
