Printing system

A method of operating a printing system, the printing system comprising a printing system according to any one of the preceding claims, the method comprising:

• performing a cleaning substrate loading operation of the printing system, the cleaning substrate loading operation comprising:
• applying a first friction setting to the supplied cleaning substrate to cause the supplied cleaning substrate to remain against the conveyor belt;
• and
• activating the conveyor belt, the first friction setting allowing the supplied cleaning substrate to be advanced by the conveyor belt;
• adjusting movement of the supplied cleaning substrate relative to the conveyor belt when the cleaning substrate is located in a cleaning position;
• performing a cleaning operation of the printing system, the cleaning operation comprising:
• applying a second friction setting, different from the first friction setting, to the supplied cleaning substrate to cause movement of the supplied cleaning substrate relative to the conveyor belt to be adjusted;
• and
• activating the conveyor belt, the second friction setting allowing the supplied cleaning substrate to slide relative to the conveyor belt.

A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a processor of a print system comprising a cleaning substrate supply mechanism to supply cleaning substrate to a conveyor belt, wherein the conveyor belt is to advance a supplied cleaning substrate, cause the processor to control the printing system to:

• perform a cleaning substrate loading operation of the printing system, the cleaning substrate loading operation comprising:
• applying a first friction setting to the supplied cleaning substrate to cause the supplied cleaning substrate to remain against the conveyor belt;
• and
• activating the conveyor belt, the first friction setting allowing the supplied cleaning substrate to be advanced by the the conveyor belt;
• adjusting movement of the supplied cleaning substrate relative to the conveyor belt when the cleaning substrate is located in a cleaning position;
• perform a cleaning operation of the printing system, the cleaning operation comprising:
• applying a second friction setting, different from the first friction setting, to the supplied cleaning substrate to cause movement of the supplied cleaning substrate relative to the conveyor belt to be adjusted;
• and
• activating the conveyor belt, the second friction setting allowing the supplied cleaning substrate to slide relative to the conveyor belt.
