looking for the technical term for the lock system you see at big companies where the person waves a card in front of the sensor, the sensor light turns from red to green and the door unlocks. What is that called? please help me.
Most often with printers the pickup rollers become dirty (paper dust, airborne dust, etc..), they may be old and have become somewhat hardened or have developed a slight glaze on the surface. The best thing to do for them is to find a rubber roller cleaner/restorer and apply with a good lint free cloth. Usually you can find the cleaner at a electronics parts supply store, sometimes the out of the way stores are where you can find them. As a last resort you can try alcohol, but that is not that good for the rubber and sometimes doesn't clean all that well. You can also try a dampened cloth with some warm water to rub off the contamination from the rollers. Try to get all the way around the rollers. Most of them will move easily by hand, on others I can sometimes cheat the paper out switch and let the printer try to pull in paper as I hold the cleaner against the rollers. Best of luck.
You should go and see a therapist. It is probably hallucinations.
Bassetnut said most of what I wanted to say. I'd also like to point out that in addition to the benefit of seeing how the dog develops and ages as well as the quality of get he produces .. in some breeds longevity is an issue (average age of death for a Bernese in the US is 7.5 years) so.. breeding to dogs OLDER than the average age of death (AOD) AND breeding to dogs from lines who routinely produce dogs who die older than the AOD is the only way to increase longevity. I would far rather risk a smaller litter due to a less viable sperm from a dog that is 12 years old in a breed that dies at 7 than to breed to a 2 or 3 year old from a line that dies at 6 (yeah, the bad thing about the AOD is its an AVERAGE which means half the dogs die YOUNGER!!!). Of course this is all a very good reason for freezing semen for later use. And, of course, a dog should only be used if he is healthy enough to withstand the rigors of breeding.
