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 the 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.
