Question about Printers & Copiers

1 Answer

I have a Canon MF4690 and when changing the toner cartridge, a small guide attached with two small springs came off and can not see how it reattaches. I think it could be the guide for 2 sided copies, but not sure.

Imageclass mf4690 has streaks in copies


Several possibilities: if copying using the ADF - clean the glass under the ADF feed. If a print is the same as a copy - check the toner cartridge. This type of cartridge collects heaps of junk in the waste chamber which interferes with the print when nearly empty. If neither of those - dust on the imaging scanner = refer to service dude.

The error code says "Toner is not set". Removing and reinstalling the toner cassette does not resolve the problem. Any ideas?


To clear this message: remove toner cartridge, look into the cavity and locate the contact that matches the contacts on the FX-9 toner cartridge.
It is on the left side of the machine.
This contact is probably caught in the down position or stuck behind the plastic.
You can wiggle it out by flexing the spring just below it.
This should allow it to spring back into place.
Now replace the cartridge and all should be fine.
hope it works for u
all the best !!!!

Canon MF4690 keeps displaying 'toner is not, set insert toner...'


Hello
I think it is firmware problem.I only found firmware update tool for MF 4150.I am not sure this is also for 4690 but i think i do this before for this machine and it works.So you can try it.It can also be a problem with cartridge contacts so yuu can try to check it.
Here is the link - in drivers software tab :

There are two contact on the right wall off the printer cartridge chamber area. They can get pushed in causing the printer cartridge to not read correctly. Take a small Flathead screwdriver and bend them up so the cartridge ink level can be read.

The Unit where you've put the toner cartridge could be to far from the drum. Make sure your developer unit (unit where you've put the cartridge in) is locked in place.
