Abstract
Cleaning of contamination in a printer, especially contamination by the use of a fixing aid, in which the contamination is determined by evaluating the register of a print of the printing machine. In the case that the register error is larger than a given amount, a cleaning run is performed. A control device is provided for evaluation of the register for determining contamination of the printer, especially by a fixing aid.
Claims4
Method for determining contamination in a printer (10), from a fixing aid, said method comprising the steps of:
- recording detecting marks (4) on a print conveyor belt (1) of a printer (10);
- detecting the detecting marks (4)
- determining a register error from the recorded detecting marks (4):
- determining contamination from a fixing aid by evaluation of the above determined register error of a print;
- and
- after reaching a certain level of register error, effecting a cleaning run of the printer (10).
3 more elements
Printer comprising:
- a device for recording detecting marks (4) on a conveyor belt (1) transported through a printer (10);
- a sensor (13) for detecting the detecting marks (4):
- a control device (20) for controlling the printer (10), said control device determining a register error of a print from the recorded detecting marks (4), and determining contamination of the printer (10) from a fixing aid by evaluation of the register error;
- and
- after reaching a certain level of register error, effecting a cleaning run of the conveyor belt (1) of the printer (10).
