This video explains how to replace a toner

2
00:00:04,237 --> 00:00:06,009
cartridge in your laser jet printer.

3
00:00:06,044 --> 00:00:09,301
First, let's go to the back of the printer.

4
00:00:11,500 --> 00:00:13,673
Turn the printer on using the power switch

5
00:00:13,708 --> 00:00:15,314
located above the power cord.

6
00:00:15,349 --> 00:00:17,797
Go back to the front of the printer.

7
00:00:18,795 --> 00:00:22,506
You will know the printer is on by
the green power light being lit up on

8
00:00:22,541 --> 00:00:24,205
the top right side of the printer.

9
00:00:24,240 --> 00:00:26,690
Next, extend the output tray.

10
00:00:30,044 --> 00:00:34,016
Open the print cartridge door to access the old cartridge.

11
00:00:35,369 --> 00:00:38,388
Grasp the handle on the cartridge

12
00:00:38,423 --> 00:00:40,394
and then pull the cartridge up to remove it.

13
00:00:43,489 --> 00:00:46,170
Once the old cartridge is removed from the printer,

14
00:00:46,205 --> 00:00:48,390
remove the new cartridge from its packaging.

15
00:00:52,991 --> 00:00:55,806
Sometimes toner can settle inside the drum

16
00:00:55,841 --> 00:00:57,687
and cause poor print quality.

17
00:00:57,722 --> 00:01:00,047
We can prevent this issue by mixing the

18
00:01:00,082 --> 00:01:02,269
toner before installing it into the printer.

19
00:01:02,304 --> 00:01:04,908
We'll hold the cartridge from its sides.

20
00:01:04,943 --> 00:01:08,442
Rotate the entire cartridge six to eight times to fully

21
00:01:08,477 --> 00:01:10,533
distribute the toner throughout the cartridge.

22
00:01:10,568 --> 00:01:13,784
Next, pull the orange tab until all the tape

23
00:01:13,819 --> 00:01:15,187
is removed from the toner cartridge.

24
00:01:20,263 --> 00:01:22,607
Be careful not to touch the imaging drum

25
00:01:22,642 --> 00:01:24,232
on the bottom of the print cartridge as this

26
00:01:24,267 --> 00:01:26,104
can cause print quality problems.

27
00:01:27,319 --> 00:01:29,170
Once the tape is completely removed,

28
00:01:29,205 --> 00:01:31,166
you can insert the cartridge into the printer.

29
00:01:32,509 --> 00:01:34,463
Close the print cartridge door.

30
00:01:37,765 --> 00:01:40,926
Your printer is now ready for regular use.
