NOTE: This procedure is to make sure that the paper feed timing is correct.
Do not change any SP mode settings when troubleshooting a paper
feed problem.
When the registration clutch, paper feed clutches, duplex feed clutch,
paper feed, or duplex feed rollers are replaced, check the paper feed
timing. Adjust if necessary.
Adjustment Standard: 12 ± 2 mm
1. Access SP mode and go to page 9 of 9 SP Adjustment (Paper Feed
Timing Adjustment).
2. Make a line [A] 20 mm [B] from the leading edge on the original [C] as
shown and make 3 copies of the original from the paper feed stations
(1st, 2nd, 3rd, duplex, by-pass, or LCT) that need to be checked.
3. Measure the distance [D] of line [E] from the leading edge of the 3 copies.
Average them.
