Mpc4500 randomly not recognizing toner

Re: Mpc4500 randomly not recognizing toner

This is what I normally do:

1. Set SP 3045 to 1 to turn off toner end detection. Toner ICON if turned on will show all toner at 100%. The toner sensor will detect when the bottle is empty.
2. If machine then runs without the problem color fading, either the chip is bad or the RFID board is bad. When the customer replaces the toner bottle with a new, never been used in any machine previously, turn SP 3045 back on and run 100 copies. If the toner empty message comes back on, the RFID board is bad. Turn SP 3045 off and order an RFID board.
3. If the color starts to fade, order a new toner pump assembly. New pumps from Ricoh include the tube that goes to the toner nozzle.

When the toner sensor on the back of the toner nozzle does not see toner coming out of the bottle.

I think we're on the same field again? You may have missed my last reply here.
At least I hope that's the case. If not tell me and I'll shut up and go away.

I think we were both typing at about the same time.

3101-01 (13,14,14,16)
Set the amount of toner remaining in the toner bottle(OEM) before the "near end" is detected.

Cut and paste directly from the MPc4500 service manual.....

---------8< insert --------------------------------------------------
Adjusts the threshold of toner near end for each color. The toner near end message appears on the LCD when the remaining toner amount reaches this threshold. When one of these SPs (SP3-101-009 to 012 or -032 to -035) reaches this threshold, toner near end is detected.
013 Near End Threshold: Bk *ENG [0 to 600 / 50 / 1 g/step]
014 Near End Threshold: M *ENG
015 Near End Threshold: C *ENG
016 Near End Threshold: Y *EN

This depends on the RFID board and toner bottle chips being functional.
