Hi folks,
I just got a new Canon Pixma MX870, but it doesn't work completely, yet.
Let me start with my setup. I run Gentoo with kernel 2.6.36-gentoo-r5 on
an Intel(R) Core(TM)2 Duo CPU T9300. I use the latest sane-backends from
GIT and sane-frontends-1.0.14.
I want to run the scanner in two different configurations - via wireless
network and via usb. I'll start with the wireless setup.
First of all, it recognizes my printer - kind of. My router (EasyBox
803) resolves all ip addresses in the local network as "localhost" and
thereby confuses SANE.
# /usr/libexec/cups/backend/bjnp
network bjnp://localhost:8611 "Canon MX870 series" "Canon MX870
series localhost"
"MFG:Canon;CMD:BJL,BJRaster3,BSCCe,NCCe,IVEC,IVECPLI;SOJ:TXT01,BJNP2;MDL:MX870
series;CLS:PRINTER;DES:Canon MX870
series;VER:1.030;STA:10;FSI:04;HRI:EU;MSI:DAT,E3,HFSF;PDR:4;"
If I add the line "bjnp://192.168.2.101:8612" to /etc/sane.d/pixma.conf,
scanimage and other applications recognize my scanner and work properly.
I attached the log file corresponding to
# export SANE_DEBUG_PIXMA=3
# scanimage -T 2> scan-net.log
ADF is working, too, but I didn't get "ADF Duplex" running (Xsane scans
one page and then stops - is this supposed to work, anyways?).
Now trying USB cable, I removed the extra line from
/etc/sane.d/pixma.conf. After attaching the USB cable, I get
# dmesg -c
usb 2-2.1: new high speed USB device using ehci_hcd and address 8
usblp0: USB Bidirectional printer dev 8 if 1 alt 0 proto 2 vid
0x04A9 pid 0x1743
scsi7 : usb-storage 2-2.1:1.2
usblp1: USB Bidirectional printer dev 8 if 3 alt 0 proto 2 vid
0x04A9 pid 0x1743
scsi 7:0:0:0: Direct-Access Canon MX870 series 0103 PQ: 0
ANSI: 2
sd 7:0:0:0: Attached scsi generic sg2 type 0
sd 7:0:0:0: [sdb] Attached SCSI removable disk
I also attached the gzipped output of
# lsusb -v > lsusb.log
Now I ran
# scanimage -T 2> scan-usb.log
The scanner makes some noises, but the command returns immediately.
Xsane fails with "Error during read: Error during device I/O".
In some forum I read that unloading ehci_hcd helps. Thus I tried
# sudo rmmod ehci_hcd
# scanimage -T 2> scan-usb2.log
The scanner shows "Processing... Please wait momentarily.", but makes no
noises of activity. Since scanimage gets stuck, I terminated it with
kill -9. The "Processing..." message only disappears on unplugging the
USB connection.
Do you have any suggestions?
Best regards
Stephan Ritscher
