Abstract

Disclosed is a method for increasing vacuum hold down pressure in an area of a vacuum transport system used in a full-width Thermal Ink Jet (TLT) printer during an envelope printing mode. By blocking off the unused side of the transport, vacuum hold down force will be diverted to the printing area, also known as the outboard side or envelope side.

ENVELOPE ENABLER (Cont'd)

.Disclosed is a method for increasing vacuum hold down pressure in an area of a vacuum transport system used in a full-width Thermal Ink Jet (TLT) printer during an envelope printing mode. By blocking off the unused side of the transport, vacuum hold down force will be diverted to the printing area, also known as the outboard side or envelope side.

Referring to the figure which illustrates the envelope printing mode, a solenoid 12 located under the inboard side 14 of marking transport 10 activates to pull a shade 16 connected by rod 18 to solenoid 12 for blocking holes 20. Blocking holes 20 shuts off the vacuum and diverts the needed vacuum pressure to outboard side 22. This action provides increased vacuum pressure to hold down an envelope (not shown) so that it can be printed and passed through a dryer (not shown) without jamming or rubbing.

Thus, the method disclosed enables envelope printing by using a blower on a split marking transport plenum and by taping off holes on the inboard side of the marking transport.
