Max paper weight on LaserJet 4 Plus?

Does anyone know what is the maximum weight of paper (grams per square
meter - as opposed to total weight) that can be used on a LaserJet 4
Plus?

I routinely feed Hammermill 8 1/2" x 11" card stock rated at 54 lb into my
LaserJet 5M, which has the same basic print engine as the LJ4+. However, I
have only used the manual feed from the front, not the tray. Makes nice
posters and business cards.

I do not know how to convert 54 lb into grams/sq m ... Ben Myers
