The model I have has the Photograde 8 mg stick in the first slot, and it didn't like the stick that I put into the second slot. Gur gives some pretty odd looking specs for ram for the Pro 630; 8,16,20,32, but no 24. 8 is achieved by the one factory installed simm. 16 is not achieved by adding another 8 mg stick, but by replacing the 8 with a 16. 20 requires a 4 and a 16 and 32, two 16's. I think mine is going to be happy with 8.
Next question. From time to time the printer does not fully eject a printed page, leaving it stuck a few inches in the slot and causing a wrinkled lower third of the page. What do you think might cause this, and how might it be remedied? Next question; what is the little green brush designed to brush? TIA > There are two RAM slots.
