Bug Description
I use a quite old, but still functioning HP 3330 mfp "all in one" device.
If scanning a document, it looks like the device stops sending data while the scan-head is driving back to start position. In around 75% of this cases, hp-scan script reports
error: Error in reading data. Status=9 bytes_read=nnnnnn.
an the scan aborts. For example:
Setting output format to JPEG for color/lineart mode.
warning: Defaulting to '/home/
Warming up...
Scanning...
Expecting to read 1.0 MB from scanner.
Reading data: [******
Closing device.

Sometimes I have to scan the same document 3 - 4 times until the scan goes through without an error.
This problem suddendly "appeared" some YEARS ago. But I always waiting for the next hplip version, hoping it would disappear agin. So I didn't file a bug report until now.
Ran hp-check script. See attached log.
Hi Norbert,
Can you try with following changes.
1) take a backup of models.dat file hplip/data/ models/ models. dat /usr/share/ hplip/data/ models/ models. dat_backup'
$ su -c 'cp /usr/share/
2) open models.dat file in root mode. hplip/data/ models/ models. dat' 3330]" string
$ su -c 'gedit /usr/share/
--> search for "[hp_laserjet_
--> few lines (around 10 lines) below, you will find "io-mfp-mode=3"
--> change from "io-mfp-mode=3" to "io-mfp-mode=1"
--> save and close file.
3) remove the print queue
$ hp-setup -r
4) restart the printer and try to do scan
If you are still facing scanning issue, send us "/var/log/messages" (if present) and "/var/log/ syslog" (if present) files.
Thanks & Regards,
Amarnath
