Hello josegerez,
I have copied an article from the DocuColor 2240 Knowledge Base that explains how to setup the Multi Purpose Tray (Tray 5) for Auto Size Detect. Auto Size Detect will not work with certain features or paper sizes, but most standard paper sizes and types will work. All of the restrictions are listed in the Knowledge Base article below. Please let me know if this does not resolve the issue.
Solution : Auto Size Detect for Tray 5 (Bypass Tray)
Certain standard paper sizes can be automatically detected in Tray 5 by selecting Auto Size Detect on the Tray 5 programming screen.
1.On the Basic Copying tab, under the Paper Supply column, select [More...].
2.Select [Tray 5]. The Tray 5 screen will be displayed.
3.Select [Auto Size Detect].
4.Use the up or down arrow buttons to select the appropriate paper type. Select Plain, Bond, Recycled, Transparency, and Lightweight to Extra Heavyweight paper.
5.Select [Save].
6.Select [Start] to make copies or [Save] to select additional features.
The following paper sizes can be used with the Auto Size Detect feature:
•US / Canada: 140 mm x 216 mm (5.5 x 8.5 inch) long edge feed (LEF) / short edge feed (SEF), 210 mm x 254 mm (8 x 10 inch) LEF, 216 mm x 279 mm (8.5 x 11 inch) LEF / SEF, 216 mm x 330 mm (8.5 x 13 inch) SEF, 216 mm x 355 mm (8.5 x 14 inch) SEF, 279 mm x 432 mm (11 x 17 inch) SEF.
