Printer or Copier for Printing an Endless Support Material Comprising Transversal Folds, and Method for Controlling Such a Printer or Copier

A method for controlling a printer or copier, comprising the steps of:

• with a first sensor arrangement, determining a position of a first transverse fold aligned on a position marking relative to an adjacent first margin hole of a web-shaped carrier material provided with margin holes;
• determining by use of a preset parameter of the carrier material a position of a second transverse fold present in the carrier material in proximity to a desired position before a transfer printing area;
• determining a second margin hole arranged at a preset first interval relative to said second transverse fold;
• and
• with a second sensor arrangement, monitoring an arrival of the second margin hole at the second sensor arrangement.

A printer or copier, comprising:

• a first sensor arrangement for determination of a position of a first transverse fold relative to an adjacent first margin hole of a web-shaped carrier material provided with margin holes, the first transverse fold being aligned on a position marking;
• a control unit that, with a preset parameter of the carrier material, determines a position of a second transverse fold present in proximity to a desired position before a transfer printing area in the carrier material and determines a second margin hole arranged at a preset interval relative to the second transverse fold;
• and
• a second sensor arrangement that monitors arrival of the second margin hole at the second sensor arrangement.

A method for controlling a printer or copier, comprising the steps of:

• with a sensor arrangement detecting points in time of arrival of at least two margin holes arranged at an interval in succession in a longitudinal direction of a web-shaped carrier material upon moving of the carrier material past said sensor arrangement;
• determining a real interval between the two margin holes by use of the detected points in time and a known transport speed;
• comparing the real interval with a desired interval;
• and
• determining an interval correction value.

A printer or copier, comprising:

• a sensor arrangement that detects points in time of arrival of at least two margin holes arranged at an interval in succession in an endless carrier material given moving of the carrier material past said sensor arrangement;
• a control unit that determines the interval between the two margin holes by use of the detected points in time and a transport speed, and which compares the determined interval with a desired interval;
• and
• the control unit determining an interval correction value.

A method for controlling a printer or copier, comprising the steps of:

• presetting as a parameter a separation of a position mark printed on a web-shaped carrier material in a longitudinal direction of the carrier material relative to a transverse fold present in the carrier material;
• monitoring arrival of the position mark with a sensor arrangement arranged before a transfer printing area while the carrier material is moved past the sensor arrangement;
• and
• determining a real position of the transverse fold for a position of arrival of the position mark at the sensor arrangement, and conveying the transverse fold to a desired position by consideration of the real position of the transverse fold.

A printer or copier, comprising:

• a control unit in which a position of a position mark printed on a web-shaped carrier material relative to a transverse fold present in the carrier material is determined stored as a parameter;
• a sensor arrangement which monitors arrival of the position mark upon moving of the carrier material past the sensor arrangement;
• the control unit determining a real position of the transverse fold by use of the determined position of the position mark;
• and
• the control unit controlling the printer or copier such that it conveys the transverse fold from the real position to a desired position.
