Description of problem: When attempting to scan a document using Samsung M2875FW over a Wifi connection the time it takes from the completion of the page scan on the scanner until it is fully received by the sane-backend is much, much longer using the latest version of the sane-backend than it was before. When a multi-page document is loaded in the automatic document feeder, only the first page is scanned. After the long delay in transmission the first page's image shows up in the xsane multipage pages list but the remaining pages are all fed through the feeder without being scanned. Version-Release number of selected component (if applicable): sane-backends-1.0.27-17.fc28.x86_64, using the xerox_mfp.conf backend with the scanner defined as follows: tcp 192.168.1.253 How reproducible: Scan any single or multi-page document using xsane in multi-page or save mode. Steps to Reproduce: 1. Set up destination directory or file for scan 2. Set scan mode to color or greyscale 3. Set color quality to full color 4. Set scan resolution to 75 dpi 2. Load 8x11 document in scanner 3. Hit "Scan" button on xsane main window Actual results: Time from scan completion on the MFP to completion of the data transfer to the PC exceeds 5 seconds and sometimes reaches over 10 seconds. If there are multiple pages in the automatic document feeder, only the first page is scanned. Expected results: Time from scan completion on the MFP to completion of the data transfer to the PC takes less than 2 seconds. If there are multiple pages, all are scanned and transferred to the PC.
