had a customer faxing a 50 page document. machine says memory full after about 20 pages. also, you can put 40 documents in the doc feeder and select two copies and sort(so it will put into memory before copying starts) and it will do the same thing.we tried the same in our demo room with a configuration page. no problems. tried a document with more toner coverage and bingo, problem showed up. add a hard drive and it fixed the problem! just memory isn't enough.
