Hi,

Replace toner hopper or use vacum cleaner to clean sensor inside hopper

There are two sensors you need to clean.

One that shines through the bottle neck & the other above the rubber diaphragm.

Re: taskalfa 3501 waste toner

I did a little experimenting a while back. This is from my notes:




I'm on U155/Waste Toner full/almost full


So, under U155 you can check the status of WTS1 & WTS2. The manual doesn't tell what the status should be. Not that I could find. I had to do a little experimenting.


If you look at the waste toner bottle, there are 2 windows on the neck of the bottle.


If you're looking at the neck of the bottle like it sits in the machine. there's one window on the left and another on the right.


A light shines thru the windows and if toner isn't blocking the light, the value of WTS1 & WTS2 = 0 for both. If toner is blocking the sensor the value = 1. I did this by using a small piece of black electrical tape.


But that was only for WTS1. I wasn't able to change the state of WTS2/near full. I'll keep working at it.


EDIT: My goal is to be able to manipulate the value of both sensors from 1 to 0 in order to determine if one of the sensors are bad (or broken wire/loose connection/bent pin, ect.) or the problem is with the waste toner bottle itself.


EDIT: You can also trick the sensors by putting a white pience of tape on the windows. So, I don't guess the light is shining thru the windows, it's reflecting off the windows back to the sensors. White reflects light. Black absorbs light. Right? Right.

It's been a while since I've worked on one of these but I think WTS2 reads the height of the bladder on top of the waste tank. When it bulges it presses a lever that engages or disengages WTS2.
I had a case some time ago where the waste tank would read full, get changed and be fine for a short while then read full again in short order. It turned out to be a broken gear in the drive that turns the auger in the waste tank.
FWIW I hope this helps.

Thanks for the information, KYO. That's why I couldn't activate WTS2. I would have never guessed it worked by air being compressed by the addition of toner thus causing the membrane to thrust upwards. Good stuff.
