Abstract
A laser printing system for multi-color and verso printing is formed of a plurality of units arranged in series which are simultaneously operated. A recording medium emerging from a paper exit region of a preceding unit is supplied to a paper entry region of the following unit. A switchable deflection means for the paper web is disposed in at least one of or between the units. The individual units can thus be constructed of individual fixing modules and printer modules which can be combined with one another. At least one fixing module follows a plurality of printer modules.
Claims21
A non-mechanical printer or copier system, comprising:
- a first preceding and a second succeeding printer or copier unit;
- the first and second units each having a developing station means at which a toner image is developed and applied to a tape-shaped recording medium at a transfer station;
- at least one of the first and second units having a solvent vapor fixing station means associated therewith for fixing the image;
- the first and second units being connected in series and simultaneously operated and wherein means are provided such that the recording medium emerging from a medium exit region of the preceding first unit is supplied to a medium entry region of the succeeding second unit;
- and
- means for selectively changing the system from verso printing to multicolor printing and vice-versa.
A printing system, comprising:
- a preceding printer unit and a succeeding printer unit;
- the preceding and succeeding units each having a developing station means at which a toner image is developed and applied to a paper tape-like sheet at a transfer station;
- at least one of the first and second units having a cold fixing station means associated therewith for fixing the image without direct heating of the sheet;
- the first and second units being connected in series and simultaneously operated;
- means being provided such that the paper sheet emerging from a paper exit region of the prededing unit is supplied to a paper entry region of the succeeding unit;
- and
- deflection means associated with the paper entry region of the succeeding unit for changing a direction of paper travel for either multicolor or verso printing.
A printer system comprising:
- first and second printer modules, each module containing a developing station means at which a toner image is developed and applied to a tape-shaped recording medium at a transfer station therein;
- a fixing module comprising a solvent vapor fixing station means for fixing the image on the tape-shaped recording medium;
- the second module being connected to follow the second module;
- the fixing module being connected to follow the second printer module;
- and
- means being provided for selectively feeding the tape-shaped recording medium form the first printer module to the second printer module for multicolor printing or for verso printing.
