weird problem on sp8200dn

**Gift** · 05-06-2011, 06:30 PM

The machine does also log quite a lot SC355 id-sensor errors - usually caused by light image density. The SMC scans are showing a light area that might interfear with the ID sensor. That shouldn't lead to paper jams but you never know if a heavy appearance of this ID sensor codes may lead to irritate other functions.

I'd probably go for fixing the image quality first to avoid SC355 - if the PM parts reached the 160k yield (or having more than 120k) I would do a PM. Otherwise clean the mag roller, vac out the pcu and printer area, check the transfer unit. You may need to perform "manual toner supply" via SP for 10 seconds, check the quality and perform another td-sensor init then.

There are also quite a lot "at power on" jams logged in the jam counter. Does the printer have a finisher installed? In this case you might also check the cover switches in the bridge unit - they tend to make improper contacts that may lead to irritate the machine. Another possible issues are the printer safety/door switches.

As suggested by Gift, sounds like a door switch is bouncing open, Ricohs are notorious for this as they are the slide type. If the printer has a bridge, replace the cover switches as there were bulletins on that subject.

Ricoh released an engine firmware for avoiding door-switch issues for most MFP/Printer a few month ago - they simply increased the timing treshold for the "door open" recognition to workaround the faulty switches. THis has been implemented to the SP8200 firmware as well but that must not mean that we don't have to care about these switches of course.

Re: weird problem on sp8200dn

After a while without having trouble about this issue last week the customer called us. Same weird problem.
We changed all the switches and also the logic board of the SR3030.
We have two of these machines (one is working fine, same type of print jobs), we swapped SR3030 and problem shifted to the other machine.

I looked for a new firmware 1.19 (RG179008k) about printer that talks about this problem, but i am not sure because the other printer is not updated to 1.19.

What can we look at?

We do regular PM on these machines (we do not change PM Kits, only needed parts), we use original toner and dev and we clean mag roller as needed (without this, would be a great machine).

Please need help, even on 15th august in sicily!

There are a lot of Jams in the Finisher exit Sensor, make sure that it is clean (use canned Air from the exit Side), also make sure, that the Sponge Rollers (B830-3503) are in good Condition.
Last, but not least, did you upgrade the Finisher Software as well? if not, do so.

Thanks for your help,
exit sensor was checked and cleaned, il will look for sponge rollers, but I can't find any new FW for SR3030.
Latest is dated 2008. We don't have Tessa Access. we can only look into Italian Ricoh's portal.
Is there any new firmware into tessa tech site?

Thanks.

Re: weird problem on sp8200dn

sounds like something is arcing, causing the machine to get lost in space, or so to speak.

Re: weird problem on sp8200dn

I looked at your smc report, i am wondering if after you pm'd the machine did the light area on the copies go away, and did you reset the sc/jam counter. There seemed to be a lot of sensor detection at the registration and tray 1, I was wondering if you replaced the feed tires in tray one area at last pm. Most of the machines that give me registration sensor/ tray issues usually is a feed roller replacement especially if they print a lot. Also if the faded area did not go away, make sure to clean the slit glass near the tonor bottle area as that can cause faded area if its dusty or has toner build up. I would make sure your not suffering issues within the machine to narrow it down to just the finisher exit, could be mylar guides causing paper to get stuck, i had bad mylars on a staple tray once which never caused an issue until they make booklets that were more then 10 pages thick the bad mylar caused the thicker stack of paper to get caught and jam the machine.

Re: weird problem on sp8200dn

Take a good look at the Junction Gate(s), it is actually two individual gates that attach to each other. The upper proof tray junction gate and the lower stapler junction gate. I have seen the plastic crack where the two attach to each other. Check right in the front where they attach to each other. Examine closely and actuate the gate and watch the action. I can see on your smc there are mainly staple jobs..... lots of pressure on the junction gates that are known to be weak. part # B7002505 , B7002500

I show latest finisher firmware to be B8045552M 12/15/2010 ( You have B8045552H )

Here is G179 current firmware listing as of August 2011. 8200dn_firmware.pdf

I agree with new sponge rollers also being a good fix with the miles you put on the unit. Constant jam code 195 (199 out of 280 total jams) steers to exit sensor so I assume this has already been addressed.

The printout sure looks like a dirty laser shield to me....... (constant SC-355 = id sensor)

SMC's are quite old. We PM almost 3 times a month the machine. ASAP I will produce new SMC's
All quality issues are well covered. A little problem may be caused by the type of prints that are very low on toner density (it's a text page produced an old MS-DOS Server).
Nowadays we are in holiday, next week we will check about your helps.

Thanks for the firmware revision, is a good help. I am still waiting for tessa access

I will provide feedback as soon I can try.

Thanks
