Single blower providing cooling and air knife
Printing apparatuses include, among other components, a media path transporting sheets of print media in a process direction. A transfer station is located at a first location of the media path, and a fusing station is located at a second location of the media path (the second location is closer to the end of the media path (in the process direction) relative to the first location). Also, a single blower is located adjacent the fusing station, and two outlets receive air from the single blower. A first outlet (of the two outlets) provides air to the transfer station to reduce the temperature of the transfer station, and a second outlet (of the two outlets) is located between the transfer station and the fusing station and directs the sheets of print media toward one side of the media path.
1. A printing apparatus comprising:
a transfer nip;
a fusing nip located adjacent said transfer nip;
a single blower located adjacent said fusing nip; and
two outlets receiving air from said single blower,
a first outlet of said two outlets providing air to said transfer nip to reduce a temperature of said transfer nip, and
a second outlet of said two outlets selectively directing only identified types of sheets of print media that are approaching said fusing nip toward one side of a media path,
said first outlet providing air to reduce said temperature of said transfer nip while said second outlet simultaneously selectively directs said sheets of print media.
2. The printing apparatus according to claim 1 , further comprising a valve located between said single blower and said second outlet.
3. The printing apparatus according to claim 2 , further comprising a processor operatively connected to said valve, said processor controlling said valve to cause said second outlet to selectively direct only said identified types of said sheets of print media toward said one side.
4. The printing apparatus according to claim 1 , said second outlet comprising an air knife.
5. The printing apparatus according to claim 1 , further comprising ducting connected to said single blower, said first outlet and said second outlet being within said ducting.
6. The printing apparatus according to claim 1 ,
said transfer nip and said fusing nip being separated by a distance that is less than a length of said sheets of print media,
said transfer nip and said fusing nip operating at different sheet feeding speeds to form a buckle in said sheets of print media, and
said second outlet directing said sheets of media in a position to properly form said buckle.
7. The printing apparatus according to claim 1 , said transfer nip being heated during printing operations, and said first outlet cooling said transfer nip to dissipate heat.
8. A printing apparatus comprising:
a transfer nip;
a fusing nip located adjacent said transfer nip;
a single blower located adjacent said fusing nip; and
two outlets receiving air from said single blower,
a first outlet of said two outlets providing air to said transfer nip to reduce a temperature of said transfer nip, and
a second outlet of said two outlets being located between said transfer nip and said fusing nip and selectively directing only identified types of sheets of print media toward one side of a media path,
said first outlet providing air to reduce said temperature of said transfer nip while said second outlet simultaneously selectively directs said sheets of print media.
9. The printing apparatus according to claim 8 , further comprising a valve located between said single blower and said second outlet.
10. The printing apparatus according to claim 9 , further comprising a processor operatively connected to said valve, said processor controlling said valve to cause said second outlet to selectively direct only said identified types of said sheets of print media toward said one side.
11. The printing apparatus according to claim 8 , said second outlet comprising an air knife.
12. The printing apparatus according to claim 8 , further comprising ducting connected to said single blower, said first outlet and said second outlet being within said ducting.
13. The printing apparatus according to claim 8 , said transfer nip and said fusing nip being separated by a distance that is less than a length of said sheets of print media,
said transfer nip and said fusing nip operating at different sheet feeding speeds to form a buckle in said sheets of print media, and
said second outlet directing said sheets of media in a position to properly form said buckle.
14. The printing apparatus according to claim 8 , said transfer nip being heated during printing operations, and said first outlet cooling said transfer nip to dissipate heat.
15. A printing apparatus comprising:
a media path transporting sheets of print media in a process direction having an end;
a transfer nip located at a first location of said media path;
a fusing nip located at a second location of said media path, said second location being closer to said end in said process direction relative to said first location;
a single blower located adjacent said fusing nip; and
two outlets receiving air from said single blower,
a first outlet of said two outlets providing air to said transfer nip to reduce a temperature of said transfer nip, and
a second outlet of said two outlets being located between said transfer nip and said fusing nip and selectively directing only identified types of said sheets of print media toward one side of said media path,
said first outlet providing air to reduce said temperature of said transfer nip while said second outlet simultaneously selectively directs said sheets of print media.
16. The printing apparatus according to claim 15 , further comprising a valve located between said single blower and said second outlet.
17. The printing apparatus according to claim 16 , further comprising a processor operatively connected to said valve, said processor controlling said valve to cause said second outlet to selectively direct only said identified types of said sheets of print media toward said one side.
18. The printing apparatus according to claim 15 , said second outlet comprising an air knife.
19. The printing apparatus according to claim 15 , further comprising ducting connected to said single blower, said first outlet and said second outlet being within said ducting.
20. The printing apparatus according to claim 15 , said transfer nip and said fusing nip being separated by a distance that is less than a length of said sheets of print media,
said transfer nip and said fusing nip operating at different sheet feeding speeds to form a buckle in said sheets of print media, and
said second outlet directing said sheets of media in a position to properly form said buckle.
