Hi there,

First time poster here. I got a GR3750 recently and I'm looking to expand my color drum collection. Is there a way to know by the 11 digit part number on a color drum if it is wide or not? I'm looking to determine this myself since many ads on eBay for drums don't mention if it is wide or not, and perhaps they are all legal size. But I'm hoping people just don't realize that they are wide, so they don't specifically mention that fact.

Any help is appreciated! Thanks.
