Apparatus for changing ink cartridges

In a printing apparatus including a stationary transport apparatus with a transport belt for flat goods, a pressing apparatus disposed opposite the transport apparatus for pressing an item of mail onto the transport belt, and a printing module, the transport belt acting in a transport region with a predetermined adhesive friction on a part of a surface of the item of mail not being printed but being close to a region to be printed, the improvement comprising:

• an apparatus for changing ink cartridges of the printing apparatus, the apparatus including a change position for the ink cartridges disposed before the transport region on a front side of the printing apparatus or above the transport region of the transport apparatus;
• deflection rollers for the transport belt, said deflection rollers having a roller carrier with a mounting plate;
• a chassis having a rear wall;
• two slide rods being fixed at the rear to said rear wall and at the front to said mounting plate;
• the printing module having a printing carriage with a guiding and sliding piece and a sliding piece sliding on said two slide rods;
• said roller carrier, said deflection rollers and the transport belt being components of the transport apparatus;
• a traverse movement device configured to move the printing module to the printing or change position, said printing position being identical to the change position;
• and
• the transport belt is a driven, wide, tensioned flat belt, and the flat belt is always guided back and forth under at least parts of the printing module.
