Possible causes for quality problems with laser printers

Posted on 20. February 2015 by robert

A poor quality, grazing on expression of laser printers can have several causes:

  1. The toner is (almost) empty.
    Then there are stripes, you are not black like other: bright stripes. This is the most common cause of quality problems.
    Solution: In this case, it often helps, the toner cartridge out of the printer to take and something to shake, distribute the remaining toner evenly over the whole width.

Posted on 1. December 2010 by robert

As with version TeamDrive 2.3.116 has introduced a restriction in the free version of the client to use its own WebDAV server, I have made myself on the search for alternatives. First, I DeltaCopy installed - but that can not deal with special characters in file names correctly even with path lengths longer than about. 256 Sign process.

Stun server configure in Pidgin

Posted on 8. November 2010 by falko

In the current version of Pidgin 2.7.5 can be in the settings (Menu / Werzeuge / Einstellungen / Netzwerk) Enter a STUN Server. A STUN server is used to, that a computer (or. In this case, Pidgin) can find, on which public IP address (and what UDP port) He can be reached, when it is itself a local IP, p.E.. has the power 192.168.xy. This is important for file transfers, where between two chat partners usually a direct connection is established.
Unfortunately, the designation “STUN-Server” Pidgin in the settings not quite right. Because Pidgin is realistic to expect there not to specify the STUN server, but the specification of a domain, within it then looks for a STUN server.
An example to illustrate:
The STUN server of the provider “Sipgate” has address stun.sipgate.net.
Now I would have expected, that you just must enter this address in pidgin, if you want to use the STUN server from sipgate. – Not at all!
In this case, try Pidgin by DNS for a STUN server and asks for:
SRV _stun._udp.stun.sipgate.net
Pidgin is looking for a server that is (SRV) in the domain stun.sipgate.net for the STUN protocol, reached by the UDP is. There is none. But under the domain sipgate.de he would find. And actually – when sipgate.de enters into the Pidgin settings, asks for Pidgin SRV _stun._udp.sipgate.de and receives a response SRV stun.sipgate.net , then uses the pidgin.
