Question 38 - 40 refer to following paragraph:

W: Hello, this is Kelly in the accounting department. (38) The ink cartridge in the printer on the fourth floor has run out. Do you think you could come to replace it today?
M: Sure. By the way, can I ask you a favor? (39) I need you to let me know what model the machine is so I can bring the correct one. Actually, I'm not in the office right now, so I can't see what it is.
W: OK. But how can I find out that information? Do I have to open the printer cover or press some function buttons?
M: No, you don't. (40) Just ask Mr. Hills in your department. He should have a complete list of all the hardware on the fourth floor.

38. What problem is the woman reporting?
