HL-2170W Laserjet Reset Drum

5.0 out of 5 starsBefore you buy.... Simply reset the drum counter

October 24, 2013

Verified Purchase

I love my Brother HL-2170W printer and always get Brother brand toner for it. After using several toner cartridges, I started to get "replace the drum" messages but I ignored them because the print quality was fine. Then finally the 'Replace Drum' light came on and the printer refused to print at all. I ordered this Brother brand drum, and when I got it I saw in the instructions that I needed to reset the drum counter after installing the drum. (Keep the power on and the front door open. Hold down the ON button until all four lights light up, then release the button and close the door.)

Just for kicks, I put the old drum back into the printer and reset the drum counter. Sure enough, the printer is now all set, printing just fine. Someday, when the print quality suffers due to streaking, etc., I'll actually open up the new drum that I have just purchased and install it. In the meantime, I'll keep resetting the drum counter.

I wish I'd tried resetting the drum counter before I ordered this. But it's good to have it on hand, just in case.

Grep with SubString

Refer: https://stackoverflow.com/questions/38270261/how-to-extract-a-string-from-between-two-patterns-in-bash

Looking for parameter between -Dappdynamics.agent.nodeName= and closing space

$ ps aux | grep -i appdynamics | grep -oP '(?<= -Dappdynamics.agent.nodeName=)[^ ]+'

$ grep -oP '(?<= -Dappdynamics.agent.nodeName=)[^ ]+' input.txt

-o tells grep to only output the matching part(s) of each line.

-P activates support for PCREs (Perl-compatible regular expressions), which support look-behind assertions such as (?<= inet:), which allow a sub-expression (inet:, in this case) to participate in matching, without being captured (returned) as part of the matched string. [^ ]+ then simply captures everything after inet: up to the first space char. (character set [^ ] matches any char. that is not (^) a space, and + matches this set 1 or more times).

Disable Autoplay in Firefox

Type about:config into the URL bar, and confirm you'll be careful by clicking the I'll be careful, I promise button. 2. Search for the string labeled media.autoplay and double-click it to flip its status to off. Opera and Chrome have an extension that prevents videos from playing automatically.
