Abstract

A technique is described whereby high speed printers, as used to process documents from a computer, are equipped with an automatic sheet/envelope feeder mechanism so as to feed single cut sheets of paper or envelopes into the printer. After printing the single sheet or envelope, the mechanism will automatically feed sheet/envelopes back out of the printer and into a stacker tray. The technique is unique in that the automatic sheet envelope feed mechanism is interchangeable with continuous forms tractor assemblies and requires no electrical connections to be made during the interchange. Furthermore, the automatic sheet/envelope feeder mechanism, described herein, combines the feeding, aligning and positioning of the sheet/envelope into one unique mechanism.

Automatic Sheet/Envelope Feeder Mechanism for High Speed Printers

A technique is described whereby high speed printers, as used to process documents from a computer, are equipped with an automatic sheet/envelope feeder mechanism so as to feed single cut sheets of paper or envelopes into the printer. After printing the single sheet or envelope, the mechanism will automatically feed sheet/envelopes back out of the printer and into a stacker tray. The technique is unique in that the automatic sheet envelope feed mechanism is interchangeable with continuous forms tractor assemblies and requires no electrical connections to be made during the interchange. Furthermore, the automatic sheet/envelope feeder mechanism, described herein, combines the feeding, aligning and positioning of the sheet/envelope into one unique mechanism. A separate mechanism is used for sheets and a separate mechanism is used for envelopes, both of which can be attached to a feed module. The mechanisms comprise three major components as follows: 1.A feed module which snaps into place within the high speed printer in place of the continuous forms feeder module. 2.A sheet paper stacker/hopper snaps into place at the top end of the feed module and extends out onto the top cover of the printer. It has both a paper input tray for handling the paper before printing and a paper output pocket for handling the paper after printing. This sheet paper stacker/hopper is capable of holding up to 100 sheets of letter-size paper. 3.An envelope stacker/hopper is used in place of the sheet paper stacker/hopper and also snaps into place at the top end of the feed module, with the main body thereof resting on the top cover of the printer. The envelope stacker/hopper is capable of holding up to 50 envelopes. The feeder module is capable of incorporating either the sheet paper stacker/hopper or th envelope stacker/hopper. The feeder module has the capability of feeding either sheets or envelopes, depending on whether the she...
