The Universal paper size is a user‑defined setting that lets you print on paper sizes that are not preset in the printer menus.
Notes:
- The smallest supported Universal size is 70
x
127
mm
(2.76
x
5
inches) for one‑sided printing and 105
x
148
mm
(4.13
x
5.83
inches) for two‑sided (duplex) printing.
- The largest supported Universal size is 216
x 356
mm
(8.5
x
14
inches) for one‑sided and two‑sided printing.
- When printing on paper less than 210
mm (8.3
inches) wide, the printer may print at a reduced speed after a period of time to ensure the best print performance.
- If you regularly print large jobs on narrow paper, then you may use the MS710 Series printer models, which print batches of 10 or more pages of narrow paper at a faster speed. For more information on the MS710 Series printer models, contact your Lexmark sales representative.
