If I compare 3.12.2 with 3.11.12 (previous stable update) I see that previously there were some resolutions hard-wired in the code. diff -r hplip-3.11.12/scan/sane/soapht.c hplip-3.12.2/scan/sane/soapht.c 516,525c517 < i=1; < session->resolutionList[i++] = 75; < session->resolutionList[i++] = 100; < session->resolutionList[i++] = 150; < session->resolutionList[i++] = 200; < session->resolutionList[i++] = 300; < session->resolutionList[i++] = 600; < //session->resolutionList[i++] = 1200; < session->resolutionList[0] = i-1; /* length of word_list */ < soapht_control_option(session, SOAP_OPTION_SCAN_RESOLUTION, SANE_ACTION_SET_AUTO, NULL, NULL); /* set default option */ --- > soapht_control_option(session, SOAP_OPTION_SCAN_RESOLUTION, SANE_ACTION_SET_AUTO, NULL, NULL); /* set default option */ It's possible that your problem (SANE returning empty list of scan resolutions for your printer) was always there but the above mentioned change uncovered it. As I have no idea where to start digging in the SANE driver I think it would be better to report this upstream. --- Additional comment from jpopelka on 2012-05-16 11:33:50 EDT --- Reported upstream as https://bugs.launchpad.net/hplip/+bug/1000299 Sam, you'll probably need to supply some more info when asked. --- Additional comment from jpopelka on 2012-05-17 06:20:37 EDT --- So, we have a soapht.c source from upstream. It's actually a 3.12.4 version with one small tweak on top of it. I built 3.12.4 without [1] and with [2] this "tweak" and need you to test both of them. First download all the .rpm files from [1] into separate directory, go into that directory and update hplip with su -c 'yum --nogpgcheck localupdate *.rpm' Close hp-systray if running. Then run 'hp-scan' or 'xsane' to do scanning. Then do the same with [2]. [1] http://koji.fedoraproject.org/koji/taskinfo?taskID=4083198 [2] http://koji.fedoraproject.org/koji/taskinfo?taskID=4083221 --- Additional comment from mail on 2012-05-17 09:35:36 EDT --- Same problem with both; the output looks identical, just formatted a bit differently. I haven't done a diff, and I didn't restart the machine or cups or anything between the updates, but I followed the procedure exactly as you said.

Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Are you able to visit the IP address for the printer using a web browser? If so, could you attach what this page says?: http://my-printer-ip-addr/Scan/ScanCaps (you might have to "Save Page As..." to save the XML file)
*** Bug 821707 has been marked as a duplicate of this bug. ***
Sorry, that should be on port 8080 I think, like this: http://my-printer-ip-addr:8080/Scan/ScanCaps
Oh, my mistake. In fact, it is not possible to debug this problem because HPLIP requires a proprietary HP plugin for that printer model. As a result it is not possible to see how it works or why it might be going wrong. Sorry.
Hi, issue is still not fixed, can one take a look at least for model HP LaserJet CM1415fn or is this also impossible? /usr/share/hplip/scan.py Issue must be caused by: valid_res = device.getOptionObj('resolution').constraint which results currently in hp-scan[20673]: debug: Device supported resolutions [] ngrep shows that resolution is still transferred somehow: <PlatenOpticalResolution><Width>1200</Width><Height>1200</Height> Here is the full ngrep of the communication of hplip until it fails: T client -> printer POST / HTTP/1.1..Host: http:0..User-Agent: gSOAP/2.7..Content-Type: application/soap+xml; charset=utf-8..Transfer-Encod ing: chunked..Connection: close.... ## T client -> printer 19E..<?xml version="1.0" encoding="UTF-8"?>.<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:x sd="http://www.w3.org/2001/XMLSchema" xmlns:wscn="http://tempuri.org/wscn.xsd"><SOAP-ENV:Body><wscn:GetScannerElements> </wscn:GetScannerElements></SOAP-ENV:Body></SOAP-ENV:Envelope>..0....

As noted, this printer requires a proprietary plugin from HP. As we do not/cannot examine the source code for this, there is no possibility of debugging it. The only way to fix it is to get HP to do so, unfortunately.

Thank you for your hint, this pushes me to investigate the plugin status....
