00:00:00,040 --> 00:00:06,680
it seems like not that long ago that handing in a freshly printed essay from

2
00:00:03,959 --> 00:00:12,480
your shiny new inkjet printer made you the coolest kid in class at least in

3
00:00:09,960 --> 00:00:17,240
your own mind anyway but nowadays printers that could have cost you a

4
00:00:14,440 --> 00:00:22,160
pretty penny in the mid 1990s are handed out like candy with new pc purchases and

5
00:00:20,039 --> 00:00:25,240
it's never been easier to afford something that will inexplicably stop

6
00:00:24,000 --> 00:00:30,679
working at 2: a.m. the night before your turn paper is due so how exactly do

7
00:00:28,320 --> 00:00:35,399
printers work and what makes them well some of them so

8
00:00:32,800 --> 00:00:39,879
unreliable now you probably already know that the two main types of printers for

9
00:00:37,120 --> 00:00:43,239
Home and Office use are inkjet and Laser unless of course you've still got one of

10
00:00:41,640 --> 00:00:46,640
those old dot matrix printers from the 80s cuz you get a kick out of tearing

11
00:00:45,160 --> 00:00:50,960
off those little strips on the edge of the paper and both of them have

12
00:00:48,719 --> 00:00:55,600
advantages and disadvantages which we actually briefly covered in this video

13
00:00:53,600 --> 00:01:02,800
but let's have a look at them in a little bit more depth first up we've got

14
00:00:59,359 --> 00:01:06,000
laser printers which use you guessed it

15
00:01:02,800 --> 00:01:08,880
a freaking laser beam to create prints

16
00:01:06,000 --> 00:01:14,040
Laser Printers also contain a rotating cylinder coated with a photosensitive

17
00:01:11,439 --> 00:01:18,920
electrically charged material and a series of mirrors when you send a

18
00:01:16,520 --> 00:01:24,439
document to a laser printer the laser light is reflected by the mirrors onto

19
00:01:21,960 --> 00:01:29,280
the cylinder which neutralizes the electrical charge in specific areas

20
00:01:27,680 --> 00:01:34,159
thanks to the rotation of both the cylinder and the the mirrors as well as

21
00:01:31,640 --> 00:01:39,360
the laser turning on and off at precisely the correct moments the areas

22
00:01:36,960 --> 00:01:44,280
hit by the laser correspond to the actual print and when toner particles

23
00:01:41,920 --> 00:01:49,600
hit the cylinder they only stick to the areas exposed to the laser light because

24
00:01:47,159 --> 00:01:54,640
the toner itself has an electrical charge too cool right then a sheet of

25
00:01:52,560 --> 00:01:59,880
paper is pressed against the cylinder and the toner is transferred through to

26
00:01:56,960 --> 00:02:04,799
the paper using heat which fuses the T owner to it which is why Pages fresh out

27
00:02:02,399 --> 00:02:09,840
of a laser printer are always so nice and cuddly warm due to the Precision of

28
00:02:07,560 --> 00:02:16,400
the laser these kinds of printers are great for producing crisp clear text the

29
00:02:13,760 --> 00:02:21,560
other major player the inkjet printer is very very different like the name says

30
00:02:19,519 --> 00:02:26,879
this sort of printer uses Liquid Ink instead of solid toner particles in

31
00:02:24,319 --> 00:02:32,400
consumer models ink inside of those expensive cartridges is heated with an

32
00:02:29,480 --> 00:02:37,959
electric charge causing a small amount to vaporize and form a bubble on the

33
00:02:34,959 --> 00:02:41,000
nozzle the bubble then collapses and the

34
00:02:37,959 --> 00:02:43,200
pressure difference pulls a droplet of

35
00:02:41,000 --> 00:02:47,840
ink out of the cartridge and onto the paper because their internal workings

36
00:02:45,599 --> 00:02:52,840
are simpler than Laser Printers they tend to be significantly cheaper and

37
00:02:50,480 --> 00:02:57,519
although they can't print as quickly they give much better print quality for

38
00:02:55,200 --> 00:03:02,800
photos making them the go-to choice if you like to print your own snapshots at

39
00:02:59,879 --> 00:03:07,599
at home unfortunately though many inkjet owners have been disappointed by their

40
00:03:04,760 --> 00:03:11,159
printer's reliability so then why is it that they seem to give people such a

41
00:03:09,120 --> 00:03:15,120
hard time well part of it is because printers have so many small moving parts

42
00:03:13,480 --> 00:03:19,760
that can break or wear out not to mention the small nozzles that can clog

43
00:03:17,440 --> 00:03:24,560
easily but perhaps a bigger part of the reason is the business model of inkjet

44
00:03:22,280 --> 00:03:30,200
manufacturers the printers themselves are frequently sold at a loss so ink

45
00:03:27,640 --> 00:03:35,360
refills can cost more than the actual printers themselves also many cartridges

46
00:03:33,519 --> 00:03:40,480
contain smart chips that report that they're empty even if there is still

47
00:03:37,760 --> 00:03:43,879
leftover ink but fortunately there are workarounds for this you can find online

48
00:03:42,439 --> 00:03:47,680
and we're even starting to see Alternatives appear on the market such

49
00:03:45,840 --> 00:03:52,879
as epson's new system that uses permanent high-capacity ink tanks

50
00:03:50,720 --> 00:03:57,360
instead of pricey cartridges which will hopefully usher in the day when we no

51
00:03:55,159 --> 00:04:03,120
longer need to sell vital organs just to afford some vacation photo printting

52
00:04:00,519 --> 00:04:09,000
speaking of things with small moving parts that need to be repaired iix it

53
00:04:06,400 --> 00:04:14,000
ifixit.com is the world's free online repair manual they've got step-by-step

repair guides and Q&A with their massive

55
00:04:14,000 --> 00:04:22,079
Community I mean we're talking they've got 15,000 plus repair guides for

56
00:04:18,560 --> 00:04:24,479

computers etc it's all wiky based and therefore always up to date you know

58
00:04:26,400 --> 00:04:33,600
hopefully as long as the community is on the ball which actually they do a pretty

59
00:04:30,520 --> 00:04:36,199
darn good job of and ifixit.com is

00:04:41,840 --> 00:04:46,720
a wide variety of tools for repairing

63
00:04:45,080 --> 00:04:49,759
all that aformentioned stuff with lifetime warranties on the tools by the

64
00:04:48,320 --> 00:04:55,800
way they got everything like their prot Tech tool kit which we use all the time

65
00:04:53,520 --> 00:04:59,280
with all these little hardto find bits and all these little adapters little

66
00:04:57,440 --> 00:05:02,720
