Allo can I know what oil

On the screen there is likely an oil can showing, it is a warning. If you touch it with your finger it will display the warning. If it is there it will come up as a "P-XX"

Trouble type	Abnormally low toner density detected yellow TCR sensor
Trouble code	C2555
Rank	B
Detection timing	When sampling data is determined in TC ratio calculation control, TCR sensor output is higher than a predetermined value for a predetermined number of times in a row even though there is toner in the sub hopper.
Trouble isolation	-
Relevant electrical parts	• Developing unit/Y,M,C,K • Toner cartridge/Y,M,C,K • Toner near empty switch/Y (RS4) • Toner near empty switch/M (RS5) • Toner near empty switch/C (RS6) • Toner near empty switch/K (RS7) • Toner cartridge motor/YM (M6) • Toner cartridge motor/CK (M7) • Toner supply motor/YM (M8) • Toner supply motor/CK (M9) • Front side relay board (FREYB) • Printer control board (PRCB)

(2) Procedure

Step	Action	Control signal	Location of electrical components
1	Perform image troubleshooting procedure if image density is low.	-	-
2	Reinstall developing unit	-	-
3	Reinstall toner cartridge	-	-
4	Check the connector between developing unit-FREYB CN4, CN6, CN8, CN10 for proper connection and correct as necessary.	-	-
5	Check the connector between FREYB CN1, CN2-PRCB CN4, CN5 for proper connection and correct as necessary.	-	-
6	M6, M7 operation check	PRCB CN13-12 to 15 (M6) PRCB CN13-16 to 19 (M7)	J-21
7	M8, M9 operation check	PRCB CN12-9 to 12 (M8) PRCB CN12-13 to 16 (M9)	J-10
8	If the toner empty sensor and its surroundings inside the sub hopper are dirtied with toner, clean them.	-	-
9	Change developing unit	--	-
10	Change FREYB	-	-
11	PRCB ICP3,4 conduction check	-	-
12	Change PRCB	-	-
