Phaser 6180MFP Multifunction Printer Service Manual 2-29
Theory of Operation
Lead Edge Registration
When a sheet is fed from Tray 1 (MPT) to the toner transfer position, the
registration of the sheet may not be correctly maintained due to misalignment
of lead edges in the tray.
To avoid this problem, the lead edge position needs to be aligned at the
Registration rollers before the sheet is fed in front of the Transfer Unit Belt, or
in front of BTR’s.
Before the Registration rollers are energized, the paper is advanced from the
tray to the rollers. This process aligns the leading edge as shown below.
By pushing the edge of the sheet coming out of Tray 1 (MPT) against the
Registration Roller that is not turning, the lead edge of the sheet is registered.
