Choose paper weight according to print coverage, duplex use, handling frequency, mailing limits, and the desired feel of the finished document. Lighter stock helps control bulk in longer reports, while heavier stock can feel more substantial and reduce show-through. The chosen weight also affects how many sheets can be punched at once and which spine size will be needed after binding. Do not use the machine’s stated sheet capacity without accounting for heavier paper, covers, tabs, or coated inserts. Test the actual printer and punch with a representative stack. This confirms feeding, toner quality, hole cleanliness, and finished thickness before a larger paper order is placed.
