Subject: Samsung SCX 4826 Blank Copies
Question: I am getting blank copies. I checked the fuse on the HVPS and it’s good. Does the HVPS go bad on this machine or is there some other place I should be looking?
Answer: Did you stop in the middle of the copy process to see if the image is on the drum unit? Did you make sure the transfer roller is set in home position? What about internal prints?
Question: I checked the machine. There is no image on the drum, and it looks like the transfer roller is seated properly. Thanks, but any other ideas?
Answer: Did you try another cartridge? There are so many things to try, got to try eliminating one thing at a time. If it’s not on the drum, then the transfer roller doesn’t matter yet. You’ve got to get the image on the drum first.
Question: I already tried a new cartridge. Copies are still blank.
Answer: Did you check to make sure the laser shutter is opening?
Question: I don’t see a shutter on this machine.
Answer: Sorry about that; you’re right, the newer ones don’t have that anymore, making them cheaper and cheaper. I’m getting away from the Samsungs because of that. It could be the HVT or main PCB as posted before.
Subject: Ricoh 3350 Admin Password Reset
Question: The customer lost the admin password; is there any way to reset to factory?
Answer: Log in to the copier or web interface as “supervisor” and change the password.
Question: I’ve tried everything, but no luck.
Answer: If you tried “Supervisor” and “supervisor,” case sensitive, it is either not being done right or you will have to replace the NVRAM.
Question: I’m having the same problem on the 1027. It works fine otherwise.
Answer: On my Savin 816/Aficio 161 I just logged in as supervisor, all lower case and no password. Click “Configuration” and the next page allows you to change the admin and supervisor names and password. So both can be changed. I just went through the service SP’s and saw nothing specific about resetting a forgotten password. You could try a “Memory Clear,” then “All” and see what happens. Of course all adjustments, including address book and network info will need to be inputted again.
Subject: Ricoh AF 1022 Noisy Exit Unit
Question: This is actually a Lanier 5622, but for all intents and purposes, it’s the same as an Aficio 1022. It makes a rapid “clicking” noise. I was certain it was the fuser unit but I’ve rebuilt the assembly and replaced the upper and lower bearings and it hasn’t changed. I’m hoping that someone has seen (or heard) this before. I think it might be coming from the exit assembly located right above the fuser. I’ve had it out a number of times but other than a spring loaded drive gear, it doesn’t seem that there’s much of any place the noise could be coming from. Any thoughts?
Answer: Did you put high temp grease on the upper fuser roller between the roller and bearings? That is where the noise comes from.
Answer: Is the frame holding the (gear side) heat roller cracked? If so, this permits the heat roller to migrate out of position. It may also be that spring loaded drive gear not “meshing” completely. Add outward pressure by “bending” the spring just a little.
Answer: I would check the exit rollers; once I had one out of position that was provoking noise.
Question: This is actually more like a “clattery” noise. I didn’t see anything that looks like the exit roller is out of position but will check again. The frame is not cracked as far as I could see and I know what you mean about the bearings “migrating” out of position. I used the bearings that have the snap ring around them and that is making it stay in place nicely. As for high temp grease on the roller, I guess that makes some sense. I have the lithium (white) grease. Is that what you would use? Does a clicking/clattering noise make sense on that? Thanks.
Answer: Now it is definitely the grease. If you don’t use it you will get the noise guaranteed. I use Chemplex 710 and have never had an issue with it.
Question: Wow! Thanks everyone. I’m off to solve this problem!
