A shield assembly is provided for use in combination an ink jet printer and is operative to provide a smooth planar surface for printing on a print media. The described embodiment includes a shield having first and second contact surfaces to define an opening therebetween. The opening of the shield assembly is aligned with the print head of the ink jet printer for permitting the deposition of ink through the opening. The assembly further includes a pivot mount operative to pivot the shield about a rotational axis which is substantially parallel to the feed path of the print media and orthogonal to the motion of the print head. Moreover, the assembly includes a means for pivoting the shield about the rotational axis in a first and second direction thereby causing one of the contact surfaces to engage the print media upstream of the print head when depositing ink on the print media.

A method and an apparatus for controlling the traveling direction of a piece of folded material in the feed path of a folding machine. A first roller nip is used to ingest the folded material into the front end of a turn chute. If the traveling direction is to be maintained, the folded material is allowed to move out through the rear end of the turn chute. If the traveling direction is to be reversed, a stop is used to block the rear end in order to keep the leading edge of the ingested folded material from leaving the turn chute through the rear end. At the same time, the trailing edge of the ingested folded material is caused to engage in a second roller nip located in the front end of the turn chute, in order for the second roller nip to move the folded material out of the turn chute, thereby reversing the traveling direction of the folded material.

A method and a printer for printing on a substrate with a plurality of print head assemblies, wherein each assembly includes at least one print head. The printer includes a roller assembly to move the substrate towards the print head assemblies along a feed path, which is substantially perpendicular to the width of the substrate. A movable fence is used to adjust the width of the feed path according to the width of the substrate. A linking arm is used to mechanically couple the print head assemblies with pivot action. The moveable fence is used to manually move the print head assemblies relative to each other via the linking arm in order to properly place the print head assemblies over the width of the feed path.

A printing system has fixed print heads in positions that are subject to adjustment between print jobs. The system provides a print preview display that includes a representation of the item of printing stock on which the printing is to be performed. The print preview display also includes a first printing field that is at a location in the representation that corresponds to the position of a first one of the print heads. The print preview display further includes a second printing field that is at a location in the representation that corresponds to the position of a second one of the print heads.

A mounting arrangement and/or stand for supporting a print feed mechanism relative to a printer. The mounting arrangement includes first and second support members defining first and second mating surfaces, respectively. The first support member is adapted to support the print feed mechanism and the second support member is adapted to support the first support member. Furthermore, the first and second mating surfaces define a mating interface or plane which is inclined relative to a horizontal plane. The relative position of the first and second support members is maintained by a means for coupling the first and second segments along the inclined mating plane. The coupling means is, furthermore, operative to selectively position the first support member relative to the second support member so as to separate the print feed mechanism segment from the printer by a fixed separation distance. The selected separation distance accommodates print media which varies in length while the inclined mating plane maintains the inclination angle of the print media at any selected separation distance.

An automatically settable date printing apparatus adapted particularly for use in postage meters which print an indicia on envelopes as they are fed seriatim past a rotary printing drum in the postage meter in which a plurality of print wheels print the day, month and year successively for each day. The apparatus includes a date print wheel assembly having individual print wheels for printing the unit day, the decade day, the month and the year for any given date. A drive wheel assembly includes a plurality of independent drive wheels for driving the date print wheels an appropriate amount, the drive wheel which is connected to the unit day print wheel being the sole source of input drive for the other drive wheels which rotate the other date print wheels by an appropriate amount through transfer components on the drive wheels. An actuating mechanism which is operated by the microprocessor of an electronic calendar controls the movement of the input drive wheel in such a manner that the print wheels are positioned to print the proper data for each successive date.

The present invention provides a method and apparatus for stacking mailpieces received from a mail-processing machine in consecutive order. There is a receiving conveying section positioned at a greater height than the following stacking conveying section. A stacking ramp extends from the downstream portion of the stacking conveying section. The receiving conveying section has a single continuous belt extending along the receiving conveying section in a first direction and positioned centrally along a second direction of the conveying section. The continuous belts of the stacking conveying section are positioned substantially at equal intervals extending along the first direction of the stacking conveying section and have top surfaces which extend above the stacking conveying section and which contact the mailpieces received from the mail processing machine. Additionally, included are means for driving the continuous belt at a first speed on the receiving conveying section in the first direction and for driving the belt at a second speed on the stacking conveying section in the same direction, the second speed of the plurality of belts is slower than the first speed of the continuous belt on the receiving conveying section. There is also a hold down means which positions and guides the mailpieces, positioned at the downstream portion of the receiving conveying section comprising normal force rollers that contact the receiving conveying belt to align the mailpieces at the receiving conveying section and guide the mailpieces onto the stacking conveying belt.

A method and apparatus for tabbing a piece of folded material with one or more tape feeders mounted on the apparatus. The tape feeder includes a roll of tape, a transporting mechanism for advancing the tape in order to release a fixed length section of the tape, wherein the released section partially extends below the traveling path of the folded material with the adhesive side facing the leading edge of the folded material, a V-shaped knife positioned above the traveling path and downstream from the released tape section, wherein the apparatus further comprises a moving mechanism to move the folded material further downstream so as to cause the released section of tape to contact and fold over the leading edge of the folded material. As the folded material moves further downstream, the released section of tape is separated by the V-shaped knife to form a tab. A pair of sealer rollers located further downstream are used to firmly press the tab across the leading edge of the folded material.
