Tech: printer feed jams?

For the past 1.5 years I’ve had a Brother HL-2040 laser printer. Running a home-based business, so typically the paper tray is filled with a stack of FedEx shipping labels interleaved with plain white paper: print a FedEx shipping label, then print a shipment record sheet on plain paper, and presto, the printer is ready for the next shipment. Worked great. Whenever I needed to print an ordinary document, I’d throw several sheets of plain paper in the tray, print, and all went well; printer never jammed.

Recently we upgraded to a Brother MFC-7440N, a wireless networked multifunction machine. The feed works fine with the shipping label/whitepaper alternating stack I described previously. But if I stick several sheets of plain white paper in the tray to print a document, this printer will reliably pick up a couple of sheets at once by the time it gets to page 3 or 4 of the document. This wouldn’t be so bad, except there’s almost always an offset of a few inches between the two sheets, so the print ends up partly on each page.

So what gives? I’m buying the cheapest paper I can from OfficeStapleDepotMax, but it seemed to feed fine in the old printer. Should I be looking for more expensive paper? Might this solve my problem?

Thanks…
