Looking for P/N A0069104 for a Ricoh 551 (Adjusting Scanner Pin (4pcs/set))

[Guest]

This part apparently shipped with the Ricoh 551 copier but is no longer with the particular copier that I'm trying to service and so I'm wondering if anyone knows where I can obtain this Scanner Pin Set P/N P/N A0069104. It's used to calibrate the scanner. Thanks muchly if anyone can offer some advise.

Take to 4 same screwdrives.

Hi
I use 4 screwdrivers that just fit the holes.
This model was prone to scanner crashes, caused by faulty scan drive PCB (MBU). Is that what has happened here?

Thanks for the advise, I was thinking that would be a last-ditch idea. Would you know offhand what diameter and length screwdrivers I should use? I only see a diagram of what the parts look like and no specs.

From what I understand, the copier was moved and it resulted in the scanner misalignment. But there are 3 sides to every story.

Take a look at the scanner rails and there are (I think) 6 holes, these are what the pins go into.
It sounds like you need a service manual. Are you a tech?
This would be pretty obvious to a trained tech from any manufacturer.

Have the manual, that's what I'm referring to. Of course it is a no brainer to look at the copier itself but I was trying to get the right tool for the job before heading over there to save time. Well, cheers.

It really is quite easy. Page 6.22 in the manual.
You should have no problem, I use 2 crosshead drivers (about .25" dia x 9" long) and line the other holes by eye.

HI, four screw drivers will do the job, but I think your scanner is skew due to the screw that breaks off in the pully, this job can be easier if you where two tech, I personally do this alone, three hours work non stop. after you´ve ajusted it manually do the SP to ajust scanner. after eight or nine broken screws on scanners it´s a piece of cake.

If you just need to move the machine, then do so. The pins you refer to are not included with the machines at all, they must be ordered as a seperate part.

As everyone has said, just use 4 screw drivers or 4 pencils/pens, or anything that fits snugly (not tightly) into the alignment holes.

IF you had a scanner crash (infamous on this model) then chances are your scanner drive pulleys (attached to either end of the single silver shaft that spans the length of the optics cavity) have sheared off the screws that bind them to the shaft. The original screws are plain pan head screws. The updated, and hardened, screws are allen screws. They are about 1/2 inch long and drive through the gear and into the shaft.

If these have sheared and you need to you can simply rotate the shaft around and, using a shorter screw, drive into the reverse side of the shaft hole. But it's not difficult to remove the sheared off screws if you work them a bit.

In the end though you need to be sure the actual problem is solved, not the symptoms....Replace the MBU, scanner motor, and in some cases, the entire PSU. Make sure firmware is updated to the latest version, for sure.

I would like to change the discussion a little...
A modified M.C.U only prevents slams in the scanner or cables to unwind,or broken exp. lamp, mirrors etc..(This can happen when customer switches on/off the copier many times to override an SC 124,101 code).
I read many times the bulleting posted above and to my point of view it does not solve the problem for ever. Am i wrong?-Maybe..if some experience could be posted from you fellows.

I have done this many times, as imind says it is easy but time consuming. I use an electric SD as there are a sh*t load of screws.
I replace all the pully screws (3) and have never had a repeat break.
I have even had to replace the shaft in one machine. Now that is a bitch.
On rebuilds we replace the screws if they are the old style.

I've never had a recurrence of the problem if I replaced not just the MCU but the scanner motor, also. This more likely has to do with another known issue for Scanner slams and the related SC's and that is the tension of the drive belt for the scanner motor. I've had to perform the procedure about 20 times and only once had to go back....when I bugged my own machine!
