Re: Mpc4502 no toner magenta

PM count on unit? Is dev unit turning? Dev on roller? Is it calling for toner, did you change tube.

Re: Mpc4502 no toner magenta

Damaged contacts on the toner bottle detection board or the back end of the bottle. Usually caused by the user slamming the bottle in rather than sliding it in gently. Could also be a bad chip on the bottle.

+1 to this. Seen lazy guys replace the pumps and not bother to install the tube that comes with the pump, only to have the same issue shortly thereafter.

Re: Mpc4502 no toner magenta

is it called a tube or a hose???????????
I pull them out and the spring loaded piece and shoot air outside and as long as they are not torn or hard resuse them.,
I hate swapping the danm yellow one as my fat hands dont fit and getting the danm connector back on always gives me
fits..
I keep meaning to make a jig but never the free time...

Rf contact on back was completely coated. Cleaned and came to ready. Only issue is for magenta only it does not show how much is in it just shows a blank column

OK
THAT SOUNDS RIGHT.....................
and from what i am led to believe these chips use RADIO freq to be read..........
Well at least you answered all the questions brought up from other techs

Most Ricoh use a non contact RFID system for the toner chips. For some reason they decided to use a contract system with this model. Highly susceptible to contact damage.

Re: Mpc4502 no toner magenta

there is a little elbow that comes off the toner reservoir in the rear of the machine that will clog up. Replace rather than clean because it will return very quickly.

this will happen because machine is now confused somehow on which toner is installed or something . perhaps the chip gets damaged? I've seen it but machine will continue to work until btl is empty just as before

Re: Mpc4502 no toner magenta

Maybe the hose has been squeezed by the transfer unit assembly after installation. There were so many holes on the back frame of the machine that techs sometimes mess up routing the hose to.
