Most jams occur due to a paper path blockage or a worn roller
The first step in image troubleshooting is to examine the toner cartridge. The toner cartridge contains the drum and developing rollers. If either of these components becomes damaged, it will result in an image problem. Inspect the drum for marks or debris.
The most common problems are scratches or lines around the drum (Figure D). These lines will transfer to the image. If the complaint is a solid or partial line on the image, inspect the drum for a matching set of lines. Replace the toner cartridge if the drum appears damaged or if you suspect the drum to be the cause of the image problem. If you replace the toner cartridge and the lines remain, then there's a good chance that the problem is with the drum.
The fuser can also be the source of image deterioration. Scratches or damaged areas of the fuser can result in missing or smudged areas on the printout. Remove the fuser, and examine it closely for damage or deterioration
recommended intervals for replacing the fuser, typically around 150,000 printed pages.
If the image appears blurred or distorted and you have ruled out the toner cartridge and fuser, check the transfer roller and laser-scanning assembly. A worn transfer roller can cause a "faded" image symptom. The transfer roller cannot be cleaned; it must be replaced. Also, dirt or debris on a lens or mirror of the laser-scanning assembly can distort the beam and cause image problems.

Bluetooth 2.0 transmission speed is
2.1 Mbit/s
Bluetooth 3.0 transmission speed is
802.11
802.11g — applies to wireless LANs and is used for transmission over short distances at up to 54-Mbps in the 2.4 GHz bands.
802.11n — 802.11n builds upon previous 802.11 standards by adding multiple-input multiple-output (MIMO). The additional transmitter and receiver antennas allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity through coding schemes like Alamouti coding. The real speed would be 100 Mbit/s (even 250 Mbit/s in PHY level), and so up to 4-5 times faster than 802.11g.
