===== troubleshooting =====

==== scanimage: open of device brother4:net1;dev0 failed: Invalid argument ====

Restart your printer. No, seriously, turn it off and on again.

==== doesn't print under Fedora with SELinux enabled ====
One possible error in ''dmesg'' can be ''lp: driver loaded but no devices found''. Fix with:

<code bash>restorecon -RFv /usr/lib/cups/filter/*
setsebool -P cups_execmem 1</code>

==== clean printer drum ====
If the [[https://support.brother.com/g/b/faqendbranchprintable.aspx?c=de&lang=de&prod=dcp9022cdw_eu&faqid=faq00002256_017&printable=true|printer is smearing ink all over the print]], the printer drum might have a stain on it.

Settings -> All Settings -> Print Reports -> Drum Dot Print

The Drum Dot Print is divided into eight sections, where you can check the location of the stain.
Remove the cartridge you want to clean, remove the toner. Place the drum on the Drum Dot Print and turn the gear on the side of the drum until you can see the stain. Remove the stain carefully with a dry cotton swab.
