Before you download the giant-size archive, please note that despite the scans having detail, the person forgot to clean the scanner window of dust as well as wipe any dust or grime off the doujinshi cover. Consequently, you get detailed scans of dust/particles. Even though it would be free, I am glad there are no pubic hairs in the scans.
Scan Problems (in order of decreasing importance): (1) Level adjustment prescan should have been made to reduce scanning problems such as glare or bloom although the scanner used seems to have registration issues. A color profile could help the software with levels, but the registration issues would remain. (2) Dirty glass window on scanner should have been cleaned (3) Dust should be wiped from doujin covers (4) I never got such small scan intervals with a usb scanner unless the bus was full of traffic or the CPU bogged down. For a 5MB scan, the intervals would normally be bigger.
