This does not sound like a hardware failure. Most of the time these errors are related to 1) bad or corrupted driver, 2) Mac related file (Adobe or PDF type) or 3) interference in the cabling.
We refer to 49 errors as "indigestion". If this pup is connected to a Mac based unit, check to see if there is a new driver available for it and if so, install it now.
If the unit is connected on a network, see if you can plug it into a different outlet and use a different patch cord.
Finally, check the file that is being sent, if it's a PDF or Adobe check again for a new driver.
Oh, and contrary to some who believe that your attempting to resolve this issue yourself is folly, good on you for giving it a go. You deserve a bonus.
