registration issue 105

[davidj7]

Hi
I am having a registartion issue on 105 , a wierd one.
I am printing multiple copies of an original book. Its all in A4 front and back .

Now the issue is the 1st set of 30 -50 pages comes okay .The second set onwards the registration starts to shift . So much as an inch and a half. I cant explain whey the first set is okay and the second sets onwards causes issue.

I replaced the registration assy , Dc board, MFC, the clutches in the back connected tp registartion , duplex assy , pick up assy , all the rollers and clutches connected to tray 1, tray 3 pickup and in the path.

Any suggestions.

is this a lead edge shift or side to side shift/



what tray location is paper feed from

MECHANICAL: Confirm that all recommended durable parts have been replaced and the machine is clean and adjusted to specification. Varied cross feed registration may be the result of the paper source (cassette/paper deck) having play in the side guides. As the paper stack is pushed in and pulled out, the side guide may get farther out of position resulting in increased variance, confirm the deck or cassette side guides are tight and not bowed.

The registration guide may become bowed while pulling the transport off the rails if the guide is depressed too hard when removing. Pull the transport all the way out and using a feeler gauge, check to make sure the entrance guide to the transport has the same gap in the front, middle and rear. Adjust bowing of guide if needed.



ELECTRICAL: Corrupt settings in service mode may cause the lead edge to vary. Perform a DCON clear in service mode.
Input door specs for service mode>ADJUST from P-PRINT or door label. Overwrite values even when the correct value is listed.
Reset out of service mode.
Power down on control panel and then power off machine using switch on the right side.
Power up machine and check values under service mode >DISPLAYS>VERSION to confirm the correct value is displayed. Test for registration issue and confirm it has been resolved.

its a lead edge to trail edge shift . i am using only A4 .not A4 R.

For Mechanical
I have replaced all parts with that from a working machine , even if remotely connected with paper path or registartion I have replaced it .

Electrical:
I have done an All Ram clear in factory mode. Secondly replaced the PCB's from that of a working machine still no change. Not even a centimeter change .

Sounds like problem in registration area, try a registration clutch, clean and lube the green spring pressure friction brakes on the front and rear of the registration roller. I know they were designed to run clean, but I lube them just the same.

hi mrfixit its been some time since we crossed paths.

I changed the whole registration assy with that from a working machine .So its not a hardware part well atleast not a registration assy issue....

[davidj7]

Hi David,

The only explanation I have for something changing the lead edge margin is problems in the registration area, I cannot see this problem being related to software, since it changes during the run. Hence, my mention of the clutch and the friction brakes. I suppose the registration roller itself could be to blame as well.

Just a thought>
what if this printer is not constantly reading A4 during the run/ could explain varying lead edge issue

guys the issue has been resolved . I cannot point to an exact solution . I replaced the clutches . cleaned the registration assy thoroughly . adjusted the values to default . etc and viola !!!.

thats for all the help

Hi David,

Glad you have it resolved,, I thought it would be the registration! I have seen the clutch slip, the brakes apply too much pressure, and the assembly binding because it was bound up.

Have a good weekend!

week end!!!! whats that . ha . well when the govt contract work comes there is no week end no holiday nothing . my machines run 24/7 for a week to a month depending on the volume. I always try to keep 5 machines running from the total 8.
