Abstract
According to an aspect there is provided a method for conditioning a blanket in an offset printer, the method comprising during a non-printing cycle of the offset printer, applying a first voltage to an intermediate transfer member of the offset printer, wherein the intermediate transfer member comprises the blanket, and maintaining the first voltage for a first period of time.
Claims11
A method for conditioning a blanket in an offset printer, the method comprising:
- during a non-printing cycle of the offset printer, applying a first voltage to an intermediate transfer member of the offset printer, wherein the intermediate transfer member comprises the blanket;
- maintaining the first voltage for a first period of time;
- and
- during the same non-printing cycle, conditioning the blanket, wherein the conditioning comprises:
- applying a second voltage to an imaging plate, wherein the second voltage has an opposite polarity of the first voltage,
- discharging the imaging plate, and
- while maintaining application of the first voltage to the intermediate transfer member, engaging the imaging plate with the intermediate transfer member.
A controller for use in an image forming apparatus, the controller comprising:
- a processor;
- and
- a memory comprising instructions that when executed on the processor cause the image forming apparatus to:
- apply a first voltage to an intermediate transfer member of the image forming apparatus during a non-printing cycle of the image forming apparatus, wherein the intermediate transfer member comprises a blanket;
- maintain the first voltage for a first period of time;
- and
- during the same non-printing cycle, condition the blanket, wherein to condition the blanket, the image forming apparatus is to:
- apply a second voltage to an imaging plate,
- discharge the imaging plate, and
- during the first period of time, engage the imaging plate with the intermediate transfer member.
An image forming apparatus comprising:
- an intermediate transfer member, the intermediate transfer member comprising a blanket;
- an imaging plate, operable to engage the intermediate transfer member;
- a power supply operable to supply a voltage to the intermediate transfer member;
- and
- a controller to cause the power supply to:
- apply a first voltage to the intermediate transfer member for a first period of time during a non-printing cycle of the image forming apparatus
- during the same non-printing cycle, condition the blanket, wherein to condition the blanket, the controller is to:
- apply a second voltage to an imaging plate,
- discharge the imaging plate, and
- during application of the first voltage to the intermediate transfer member, engage the imaging plate with the intermediate transfer member.
A non-transitory computer readable medium comprising computer program code configured when executed on a processor to cause an offset printer to implement a method comprising:
- during a non-printing cycle of the offset printer, apply a first voltage to an intermediate transfer member of the offset printer, wherein the intermediate transfer member comprises a blanket;
- and
- maintain the first voltage for a first period of time;
- during the same non-printing cycle, condition the blanket, wherein to condition the blanket, the offset printer is to:
- apply a second voltage to an imaging plate,
- discharge the imaging plate, and
- during maintenance of the first voltage, engage the imaging plate with the intermediate transfer member.
