Photo: Inside the MP990
Again, as a compact all-in-one, I have nothing but praise for the MP990. Just to test things out, I ran the unit over WiFi and had no trouble, even though Canon’s network utility reported only receiving a moderate signal. Top-resolution scans took roughly 10 minutes each, which is ungodly slow when you’re sitting in front of it but not unusual in this device class.
The padded white panel built into the MP990's lid snaps out to expose the unit’s single 35 mm slide and film carrier as well as the film scanner’s illumination strip. (For those curious about the pencils in my plant shown in this picture, I had to install makeshift Punji sticks to keep my cat out of the dirt.) With the MP990, you get a single carrier for both 35 mm slides and film strips.
The carrier has a tab at each end that fits into a notch in the plastic bezel around the flatbed glass. This keeps the carrier straight and aligned with the illumination bar. That black insert you see within the gray carrier frame is what holds the film strip. If you need to scan slides, the insert lifts out and you merely set the slides on the glass within any of the carrier’s four slide sections.
