Patent ID: 7065308

Claim:
A method of maintaining a rotational velocity of an imaging drum during engagement with a transfer roll in an image producing device comprising: forming a nip to transfer an image from said imaging drum to media when said imaging drum is in engagement with the transfer roll; maintaining a substantially constant imaging drum rotational velocity mode during engagement with the transfer roll; sensing a lead edge of portion of said media prior to entering the nip; activating torque assist to increase the velocity of said transfer roll when said media is in said nip for a defined period; resuming said substantially constant imaging drum rotational velocity mode while a second portion of said media is in the nip; and sensing the trailing of said media prior enter the nip; activating torque assist to decrease the velocity of said transfer roll when said media is in said nip for a second defined period; and resuming said substantially constant imaging drum rotational velocity mode after said media has left the nip.
