Ricoh 1515 - дon't spin the bottle

[milenjs]

Display add toner. But the new bottle but not loading toner. The old one was half full. After few checks - the bottle does not rotate. Force in service mode add toner manually - again the bottle does not rotate. I disconnected the toner supply clutch connector from main pcb and connect to 24V DC power for test. Result - bottle is spinning. What could be the problem? Something software or main PCB damage?

Last thing I would test is the clutch via output check. If the clutch can't be enganged this way it's driver IC on the I/O board might be fried for some reason.

if i remember well in that model, there was something about toner bottle revolver unit, that pressed a switch, or a plastic lever, that broke or go out position (?) and give that message...check well, but it's been a long time.

I looked carefully - unfortunately there is no sensor for the module with the bottle.

I think this engine is too stupid so there is no actual detection for the bottle but there is indeed some mechanics that can disturb the toner-flow into the PCDU. But I don't think this is the problem if the bottle doesn't turn during the "addindg toner" display. Another common issues with the entire series is that you shouldn't swap the toner too fast -it seems the front cover must stay open at least for ~30 seconds, otherwise the engine won't even try to recover from a toner end condition.

..i remember now, give sc320

we no longer have the manual of that machine, try like this, open front and right panel with machine on, and take out the pcdu and reinsert it.
if negative, you can do this, reset the signal with sp "clear toner end", then print sp990 (if any, non-standard), and reset sp801 "engine", restart, and re-enter all the data you printed

Have you tried another PCDU or a rebuild.

But this is such an old model why waste your time.

You probably need a new toner supply unit ( the thing the toner bottle sits in). There was an issue with the mylars falling off inside and blocking toner supply.

Now i try without toner hopper and get error sc322.
I have and MP161, You will take the bottle, hopper and PCDU from him for test and try it.

Take the cover off the internal tray to expose the toner bottle. If it is NOT turning, I've seen where the toner feed mechanism spring is compressed away from the toner bottle. Press on it, it should freely move in and out pressing against the toner bottle. If this is your problem, remove the back cover, you can see the toner feed clutch and the feed shaft will be sticking out. Be gentle, add some penetrating lube and tap the shaft back towards the inside of the machine. What holds the clutch in place is the frame of the machine. Push too hard and Break it...and your machine is a "Brick".

I don't think there is a clutch on these POS entry level models. But there is a spring loaded coupling on the toner add motor. The motor is on the back of the plastic back frame and the coupling on the front. The shaft passes through the frame and eventually starts to stick to the point that the spring will no longer push it forward to engage the bottle. If you are lucky you can get the coupling off of the frame to clean it. If you break the shaft or the frame, have fun finding replacements.

Better idea, time for the 1515 to go to the scrap heap and be replaced with something new.

Re: Ricoh 1515 - дon't spin the bottle

There's a spring in the clutch that pushes the clutch shaft against the toner bottle. Sometimes it gets stuck.Capturar.JPG

Re: Ricoh 1515 - дon't spin the bottle

When i put 24V to clutch connector - the bottle is start spinning. For me - no command from main pcb to clutch. But why? Tomorrow i check with other toner hoper ad pcdu.
Machine is old, but only 350k copies, working god. Until now.

This is a bit a tricky machine to detect if the toner clutch is turning the bottle.

This is what I would do:
make sure the machine is on and started up. Enter sp mode and make a note of Vt and Vts. If the machine is calling for toner then your Vt will be higher then your Vts. open only the front door. Slide the tray (hopper unit) that holds the bottle out. Mark position of toner bottle. Wait about 30 seconds. Then slide the toner tray (hopper unit) back in.

After that the machine should go into a cycle and rotate the toner bottle. After the machine stops cycling 1 of 2 things will happen, either the toner light will go off or stay on. If it goes off enter the SP mode and go to 2-221 check your Vt and Vts. At this point your Vt should be close to your Vts. Now open the front cover and slide toner out. The bottle should have turned. If it has not replace the clutch and test again.

If the bottle has turned, you need to still monitor the machine to make sure that the machine is adding a sufficient amount of toner. Those clutch are notorious for malfunctioning when they get old. I know, I changed a toner clutch , 2 weeks ago that had gone faulty. The toner feed clutch is the same in the 1515, 161, 171, 201.

It is unlikely that the BICU board would malfunction. Change it only as a last resort.

Also... What Slimslob said is most likely the best advice... Replace the 15 year old machine with something newer.

All the best friend

Go with sp801 "engine" and reboot
